### Guix Introduction
This PR enables building bitcoin in Guix containers. [Guix](https://www.gnu.org/software/guix/manual/en/html_node/Features.html) is a transactional package manager much like Nix, but unlike Nix, it has more of a focus on [bootstrappability](https://www.gnu.org/software/guix/manual/en/html_node/Bootstrapping.html) and [reproducibility](https://www.gnu.org/software/guix/blog/tags/reproducible-builds/) which are attractive for security-sensitive projects like bitcoin.
### Guix Build Walkthrough

<summary>Old instructions no. 1</summary>
In this PR, we define a Guix [manifest](https://www.gnu.org/software/guix/manual/en/html_node/Invoking-guix-package.html#profile_002dmanifest) in `contrib/guix/manifest.scm`, which declares what packages we want in our environment.
We can then invoke
```
guix environment --manifest=contrib/guix/manifest.scm --container --pure --no-grafts --no-substitutes
```
To have Guix:
1. Build an environment containing the packages we defined in our `contrib/guix/manifest.scm` manifest from the Guix bootstrap binaries (see [bootstrappability](https://www.gnu.org/software/guix/manual/en/html_node/Bootstrapping.html) for more details).
2. Start a container with that environment that has no network access, and no access to the host's filesystem except to the `pwd` that it was started in.
3. Drop you into a shell in that container.
> Note: if you don't want to wait hours for Guix to build the entire world from scratch, you can eliminate the `--no-substitutes` option to have Guix download from available binary sources. Note that this convenience doesn't necessarily compromise your security, as you can check that a package was built correctly after the fact using `guix build --check <packagename>`
Therefore, we can perform a build of bitcoin much like in Gitian by invoking the following:
```
make -C depends -j"$(nproc)" download && \
cat contrib/guix/build.sh | guix environment --manifest=contrib/guix/manifest.scm --container --pure --no-grafts --no-substitutes
```
We don't include `make -C depends -j"$(nproc)" download` inside `contrib/guix/build.sh` because `contrib/guix/build.sh` is run inside the container, which has no network access (which is a good thing).
</details>
### Rationale
I believe that this represents a substantial improvement for the "supply chain security" of bitcoin because:
1. We no longer have to rely on Ubuntu for our build environment for our releases ([oh the horror](https://github.com/bitcoin/bitcoin/blob/72bd4ab867e3be0d8410403d9641c08288d343e3/contrib/gitian-descriptors/gitian-linux.yml#L10)), because Guix builds everything about the container, we can perform this on almost any Linux distro/system.
2. It is now much easier to determine what trusted binaries are in our supply chain, and even make a nice visualization! (see [bootstrappability](https://www.gnu.org/software/guix/manual/en/html_node/Bootstrapping.html)).
3. There is active effort among Guix folks to minimize the number of trusted binaries even further. OriansJ's [stage0](https://github.com/oriansj/stage0), and janneke's [Mes](https://www.gnu.org/software/mes/) all aim to achieve [reduced binary boostrap](http://joyofsource.com/reduced-binary-seed-bootstrap.html) for Guix. In fact, I believe if OriansJ gets his way, we will end up some day with only a single trusted binary: hex0 (a ~500 byte self-hosting hex assembler).
### Steps to Completion
- [x] Successfully build bitcoin inside the Guix environment
- [x] Make `check-symbols` pass
- [x] Do the above but without nasty hacks
- [x] Solve some of the more innocuous hacks
- [ ] Make it cross-compile (HELP WANTED HERE)
- [x] Linux
- [x] x86_64-linux-gnu
- [x] i686-linux-gnu
- [x] aarch64-linux-gnu
- [x] arm-linux-gnueabihf
- [x] riscv64-linux-gnu
- [ ] OS X
- [ ] x86_64-apple-darwin14
- [ ] Windows
- [ ] x86_64-w64-mingw32
- [ ] Maybe make importer for depends syntax
- [ ] Document build process for future releases
- [ ] Extra: Pin the revision of Guix that we build with with Guix [inferiors](https://www.gnu.org/software/guix/manual/en/html_node/Inferiors.html)

As of now, the command described above to perform a build of bitcoin a lot like Gitian works, but fails at the `check-symbols` stage. This is because a few dynamic libraries are linked in that shouldn't be.
Here's what `ldd src/bitcoind` looks like when built in a Guix container:
```
linux-vdso.so.1 (0x00007ffcc2d90000)
libdl.so.2 => /gnu/store/h90vnqw0nwd0hhm1l5dgxsdrigddfmq4-glibc-2.28/lib/libdl.so.2 (0x00007fb7eda09000)

libpthread.so.0 => /gnu/store/h90vnqw0nwd0hhm1l5dgxsdrigddfmq4-glibc-2.28/lib/libpthread.so.0 (0x00007fb7ed85b000)
libm.so.6 => /gnu/store/h90vnqw0nwd0hhm1l5dgxsdrigddfmq4-glibc-2.28/lib/libm.so.6 (0x00007fb7ed6da000)
libgcc_s.so.1 => /gnu/store/4sqps8dczv3g7rwbdibfz6rf5jlk7w90-gcc-5.5.0-lib/lib/libgcc_s.so.1 (0x00007fb7ed6bf000)
libc.so.6 => /gnu/store/h90vnqw0nwd0hhm1l5dgxsdrigddfmq4-glibc-2.28/lib/libc.so.6 (0x00007fb7ed506000)
/gnu/store/h90vnqw0nwd0hhm1l5dgxsdrigddfmq4-glibc-2.28/lib/ld-linux-x86-64.so.2 => /usr/lib64/ld-linux-x86-64.so.2 (0x00007fb7ee3a0000)
```
And here's what it looks in one of our releases:
```
linux-vdso.so.1 (0x00007ffff52cd000)
libpthread.so.0 => /usr/lib/libpthread.so.0 (0x00007f87726b4000)

libgcc_s.so.1 => /usr/lib/libgcc_s.so.1 (0x00007f877250b000)
libc.so.6 => /usr/lib/libc.so.6 (0x00007f8772347000)
/lib64/ld-linux-x86-64.so.2 => /usr/lib64/ld-linux-x86-64.so.2 (0x00007f8773392000)
```
~~I suspect it is because my script does not apply the gitian-input patches [described in the release process](https://github.com/bitcoin/bitcoin/blob/master/doc/release-process.md#fetch-and-create-inputs-first-time-or-when-dependency-versions-change) but there is no description as to how these patches are applied.~~ It might also be something else entirely.
Edit: It is something else. It appears that the gitian inputs are only used by [`gitian-win-signer.yml`](https://github.com/bitcoin/bitcoin/blob/d6e700e40f861ddd6743f4d13f0d6f6bc19093c2/contrib/gitian-descriptors/gitian-win-signer.yml#L14)

### How to Help
1. Install Guix on your distro either [from source](https://www.gnu.org/software/guix/manual/en/html_node/Requirements.html) or perform a [binary installation](https://www.gnu.org/software/guix/manual/en/html_node/Binary-Installation.html#Binary-Installation)

In fact, I believe if OriansJ gets his way, we will end up some day with only a single trusted binary: hex0 (a ~500 byte self-hosting hex assembler).

As of now, the command described above to perform a build of bitcoin a lot like Gitian works, but fails at the `check-symbols` stage. This is because a few dynamic libraries are linked in that shouldn't be.
Here's what `ldd src/bitcoind` looks like when built in a Guix container:
```
linux-vdso.so.1 (0x00007ffcc2d90000)

And here's what it looks in one of our releases:

~~I suspect it is because my script does not apply the gitian-input patches [described in the release process](https://github.com/bitcoin/bitcoin/blob/master/doc/release-process.md#fetch-and-create-inputs-first-time-or-when-dependency-versions-change) but there is no description as to how these patches are applied.~~ It might also be something else entirely.
Edit: It is something else. It appears that the gitian inputs are only used by [`gitian-win-signer.yml`](https://github.com/bitcoin/bitcoin/blob/d6e700e40f861ddd6743f4d13f0d6f6bc19093c2/contrib/gitian-descriptors/gitian-win-signer.yml#L14)

### Guix Introduction
This PR enables building bitcoin in Guix containers. [Guix](https://www.gnu.org/software/guix/manual/en/html_node/Features.html) is a transactional package manager much like Nix, but unlike Nix, it has more of a focus on [bootstrappability](https://www.gnu.org/software/guix/manual/en/html_node/Bootstrapping.html) and [reproducibility](https://www.gnu.org/software/guix/blog/tags/reproducible-builds/) which are attractive for security-sensitive projects like bitcoin.
### Guix Build Walkthrough
Please read the `README.md`.

<summary>Old instructions no. 1</summary>
In this PR, we define a Guix [manifest](https://www.gnu.org/software/guix/manual/en/html_node/Invoking-guix-package.html#profile_002dmanifest) in `contrib/guix/manifest.scm`, which declares what packages we want in our environment.
We can then invoke
```
guix environment --manifest=contrib/guix/manifest.scm --container --pure --no-grafts --no-substitutes
```
To have Guix:
1. Build an environment containing the packages we defined in our `contrib/guix/manifest.scm` manifest from the Guix bootstrap binaries (see [bootstrappability](https://www.gnu.org/software/guix/manual/en/html_node/Bootstrapping.html) for more details).
2. Start a container with that environment that has no network access, and no access to the host's filesystem except to the `pwd` that it was started in.
3. Drop you into a shell in that container.
> Note: if you don't want to wait hours for Guix to build the entire world from scratch, you can eliminate the `--no-substitutes` option to have Guix download from available binary sources. Note that this convenience doesn't necessarily compromise your security, as you can check that a package was built correctly after the fact using `guix build --check <packagename>`
Therefore, we can perform a build of bitcoin much like in Gitian by invoking the following:
```
make -C depends -j"$(nproc)" download && \
cat contrib/guix/build.sh | guix environment --manifest=contrib/guix/manifest.scm --container --pure --no-grafts --no-substitutes
```
We don't include `make -C depends -j"$(nproc)" download` inside `contrib/guix/build.sh` because `contrib/guix/build.sh` is run inside the container, which has no network access (which is a good thing).
</details>
### Rationale
I believe that this represents a substantial improvement for the "supply chain security" of bitcoin because:
1. We no longer have to rely on Ubuntu for our build environment for our releases ([oh the horror](https://github.com/bitcoin/bitcoin/blob/72bd4ab867e3be0d8410403d9641c08288d343e3/contrib/gitian-descriptors/gitian-linux.yml#L10)), because Guix builds everything about the container, we can perform this on almost any Linux distro/system.
2. It is now much easier to determine what trusted binaries are in our supply chain, and even make a nice visualization! (see [bootstrappability](https://www.gnu.org/software/guix/manual/en/html_node/Bootstrapping.html)).
3. There is active effort among Guix folks to minimize the number of trusted binaries even further.

### Guix Introduction
This PR enables building bitcoin in Guix containers. [Guix](https://www.gnu.org/software/guix/manual/en/html_node/Features.html) is a transactional package manager much like Nix, but unlike Nix, it has more of a focus on [bootstrappability](https://www.gnu.org/software/guix/manual/en/html_node/Bootstrapping.html) and [reproducibility](https://www.gnu.org/software/guix/blog/tags/reproducible-builds/) which are attractive for security-sensitive projects like bitcoin.
### Guix Build Walkthrough
Please read the `README.md`.

<details>
<summary>Old instructions no. 1</summary>
In this PR, we define a Guix [manifest](https://www.gnu.org/software/guix/manual/en/html_node/Invoking-guix-package.html#profile_002dmanifest) in `contrib/guix/manifest.scm`, which declares what packages we want in our environment.
We can then invoke
```
guix environment --manifest=contrib/guix/manifest.scm --container --pure --no-grafts --no-substitutes
```
To have Guix:
1. Build an environment containing the packages we defined in our `contrib/guix/manifest.scm` manifest from the Guix bootstrap binaries (see [bootstrappability](https://www.gnu.org/software/guix/manual/en/html_node/Bootstrapping.html) for more details).
2. Start a container with that environment that has no network access, and no access to the host's filesystem except to the `pwd` that it was started in.
3. Drop you into a shell in that container.
> Note: if you don't want to wait hours for Guix to build the entire world from scratch, you can eliminate the `--no-substitutes` option to have Guix download from available binary sources. Note that this convenience doesn't necessarily compromise your security, as you can check that a package was built correctly after the fact using `guix build --check <packagename>`
Therefore, we can perform a build of bitcoin much like in Gitian by invoking the following:
```
make -C depends -j"$(nproc)" download && \
cat contrib/guix/build.sh | guix environment --manifest=contrib/guix/manifest.scm --container --pure --no-grafts --no-substitutes
```
We don't include `make -C depends -j"$(nproc)" download` inside `contrib/guix/build.sh` because `contrib/guix/build.sh` is run inside the container, which has no network access (which is a good thing).
</details>
### Rationale
I believe that this represents a substantial improvement for the "supply chain security" of bitcoin because:
1. We no longer have to rely on Ubuntu for our build environment for our releases ([oh the horror](https://github.com/bitcoin/bitcoin/blob/72bd4ab867e3be0d8410403d9641c08288d343e3/contrib/gitian-descriptors/gitian-linux.yml#L10)), because Guix builds everything about the container, we can perform this on almost any Linux distro/system.
2. It is now much easier to determine what trusted binaries are in our supply chain, and even make a nice visualization! (see [bootstrappability](https://www.gnu.org/software/guix/manual/en/html_node/Bootstrapping.html)).
3. There is active effort among Guix folks to minimize the number of trusted binaries even further. OriansJ's [stage0](https://github.com/oriansj/stage0), and janneke's [Mes](https://www.gnu.org/software/mes/) all aim to achieve [reduced binary boostrap](http://joyofsource.com/reduced-binary-seed-bootstrap.html) for Guix. In fact, I believe if OriansJ gets his way, we will end up some day with only a single trusted binary: hex0 (a ~500 byte self-hosting hex assembler).
### Steps to Completion
- [x] Successfully build bitcoin inside the Guix environment
- [x] Make `check-symbols` pass
- [x] Do the above but without nasty hacks
- [x] Solve some of the more innocuous hacks
- [ ] Make it cross-compile (HELP WANTED HERE)
- [x] Linux
- [x] x86_64-linux-gnu
- [x] i686-linux-gnu
- [x] aarch64-linux-gnu
- [x] arm-linux-gnueabihf
- [x] riscv64-linux-gnu
- [ ] OS X
- [ ] x86_64-apple-darwin14
- [ ] Windows
- [ ] x86_64-w64-mingw32
- [ ] Maybe make importer for depends syntax
- [ ] Document build process for future releases
- [ ] Extra: Pin the revision of Guix that we build with with Guix [inferiors](https://www.gnu.org/software/guix/manual/en/html_node/Inferiors.html)

As of now, the command described above to perform a build of bitcoin a lot like Gitian works, but fails at the `check-symbols` stage. This is because a few dynamic libraries are linked in that shouldn't be.
Here's what `ldd src/bitcoind` looks like when built in a Guix container:

### Guix Introduction
This PR enables building bitcoin in Guix containers. [Guix](https://www.gnu.org/software/guix/manual/en/html_node/Features.html) is a transactional package manager much like Nix, but unlike Nix, it has more of a focus on [bootstrappability](https://www.gnu.org/software/guix/manual/en/html_node/Bootstrapping.html) and [reproducibility](https://www.gnu.org/software/guix/blog/tags/reproducible-builds/) which are attractive for security-sensitive projects like bitcoin.

In this PR, we define a Guix [manifest](https://www.gnu.org/software/guix/manual/en/html_node/Invoking-guix-package.html#profile_002dmanifest) in `contrib/guix/manifest.scm`, which declares what packages we want in our environment.
We can then invoke
```
guix environment --manifest=contrib/guix/manifest.scm --container --pure --no-grafts --no-substitutes
```
To have Guix:
1. Build an environment containing the packages we defined in our `contrib/guix/manifest.scm` manifest from the Guix bootstrap binaries (see [bootstrappability](https://www.gnu.org/software/guix/manual/en/html_node/Bootstrapping.html) for more details).
2. Start a container with that environment that has no network access, and no access to the host's filesystem except to the `pwd` that it was started in.
3. Drop you into a shell in that container.
> Note: if you don't want to wait hours for Guix to build the entire world from scratch, you can eliminate the `--no-substitutes` option to have Guix download from available binary sources. Note that this convenience doesn't necessarily compromise your security, as you can check that a package was built correctly after the fact using `guix build --check <packagename>`
Therefore, we can perform a build of bitcoin much like in Gitian by invoking the following:
```
make -C depends -j"$(nproc)" download && \
cat contrib/guix/build.sh | guix environment --manifest=contrib/guix/manifest.scm --container --pure --no-grafts --no-substitutes
```
We don't include `make -C depends -j"$(nproc)" download` inside `contrib/guix/build.sh` because `contrib/guix/build.sh` is run inside the container, which has no network access (which is a good thing).
</details>
### Rationale
I believe that this represents a substantial improvement for the "supply chain security" of bitcoin because:
1. We no longer have to rely on Ubuntu for our build environment for our releases ([oh the horror](https://github.com/bitcoin/bitcoin/blob/72bd4ab867e3be0d8410403d9641c08288d343e3/contrib/gitian-descriptors/gitian-linux.yml#L10)), because Guix builds everything about the container, we can perform this on almost any Linux distro/system.
2. It is now much easier to determine what trusted binaries are in our supply chain, and even make a nice visualization! (see [bootstrappability](https://www.gnu.org/software/guix/manual/en/html_node/Bootstrapping.html)).
3. There is active effort among Guix folks to minimize the number of trusted binaries even further. OriansJ's [stage0](https://github.com/oriansj/stage0), and janneke's [Mes](https://www.gnu.org/software/mes/) all aim to achieve [reduced binary boostrap](http://joyofsource.com/reduced-binary-seed-bootstrap.html) for Guix. In fact, I believe if OriansJ gets his way, we will end up some day with only a single trusted binary: hex0 (a ~500 byte self-hosting hex assembler).
### Steps to Completion
- [x] Successfully build bitcoin inside the Guix environment

- [x] Do the above but without nasty hacks

As of now, the command described above to perform a build of bitcoin a lot like Gitian works, but fails at the `check-symbols` stage. This is because a few dynamic libraries are linked in that shouldn't be.
Here's what `ldd src/bitcoind` looks like when built in a Guix container:
```
linux-vdso.so.1 (0x00007ffcc2d90000)
libdl.so.2 => /gnu/store/h90vnqw0nwd0hhm1l5dgxsdrigddfmq4-glibc-2.28/lib/libdl.so.2 (0x00007fb7eda09000)

```
And here's what it looks in one of our releases:
```

```
~~I suspect it is because my script does not apply the gitian-input patches [described in the release process](https://github.com/bitcoin/bitcoin/blob/master/doc/release-process.md#fetch-and-create-inputs-first-time-or-when-dependency-versions-change) but there is no description as to how these patches are applied.~~ It might also be something else entirely.

We no longer have to rely on Ubuntu for our build environment for our releases ([oh the horror](https://github.com/bitcoin/bitcoin/blob/72bd4ab867e3be0d8410403d9641c08288d343e3/contrib/gitian-descriptors/gitian-linux.yml#L10)), because Guix builds everything about the container, we can perform this on almost any Linux distro/system.
2. It is now much easier to determine what trusted binaries are in our supply chain, and even make a nice visualization! (see [bootstrappability](https://www.gnu.org/software/guix/manual/en/html_node/Bootstrapping.html)).
3. There is active effort among Guix folks to minimize the number of trusted binaries even further. OriansJ's [stage0](https://github.com/oriansj/stage0), and janneke's [Mes](https://www.gnu.org/software/mes/) all aim to achieve [reduced binary boostrap](http://joyofsource.com/reduced-binary-seed-bootstrap.html) for Guix. In fact, I believe if OriansJ gets his way, we will end up some day with only a single trusted binary: hex0 (a ~500 byte self-hosting hex assembler).

As of now, the command described above to perform a build of bitcoin a lot like Gitian works, but fails at the `check-symbols` stage. This is because a few dynamic libraries are linked in that shouldn't be.
Here's what `ldd src/bitcoind` looks like when built in a Guix container:
```
linux-vdso.so.1 (0x00007ffcc2d90000)
libdl.so.2 => /gnu/store/h90vnqw0nwd0hhm1l5dgxsdrigddfmq4-glibc-2.28/lib/libdl.so.2 (0x00007fb7eda09000)

```
And here's what it looks in one of our releases:
```

~~I suspect it is because my script does not apply the gitian-input patches [described in the release process](https://github.com/bitcoin/bitcoin/blob/master/doc/release-process.md#fetch-and-create-inputs-first-time-or-when-dependency-versions-change) but there is no description as to how these patches are applied.~~ It might also be something else entirely.
Edit: It is something else. It appears that the gitian inputs are only used by [`gitian-win-signer.yml`](https://github.com/bitcoin/bitcoin/blob/d6e700e40f861ddd6743f4d13f0d6f6bc19093c2/contrib/gitian-descriptors/gitian-win-signer.yml#L14)

### Guix Introduction
This PR enables building bitcoin in Guix containers. [Guix](https://www.gnu.org/software/guix/manual/en/html_node/Features.html) is a transactional package manager much like Nix, but unlike Nix, it has more of a focus on [bootstrappability](https://www.gnu.org/software/guix/manual/en/html_node/Bootstrapping.html) and [reproducibility](https://www.gnu.org/software/guix/blog/tags/reproducible-builds/) which are attractive for security-sensitive projects like bitcoin.

In this PR, we define a Guix [manifest](https://www.gnu.org/software/guix/manual/en/html_node/Invoking-guix-package.html#profile_002dmanifest) in `contrib/guix/manifest.scm`, which declares what packages we want in our environment.
We can then invoke
```
guix environment --manifest=contrib/guix/manifest.scm --container --pure --no-grafts --no-substitutes
```
To have Guix:
1. Build an environment containing the packages we defined in our `contrib/guix/manifest.scm` manifest from the Guix bootstrap binaries (see [bootstrappability](https://www.gnu.org/software/guix/manual/en/html_node/Bootstrapping.html) for more details).
2. Start a container with that environment that has no network access, and no access to the host's filesystem except to the `pwd` that it was started in.
3. Drop you into a shell in that container.
> Note: if you don't want to wait hours for Guix to build the entire world from scratch, you can eliminate the `--no-substitutes` option to have Guix download from available binary sources. Note that this convenience doesn't necessarily compromise your security, as you can check that a package was built correctly after the fact using `guix build --check <packagename>`
Therefore, we can perform a build of bitcoin much like in Gitian by invoking the following:
```
make -C depends -j"$(nproc)" download && \
cat contrib/guix/build.sh | guix environment --manifest=contrib/guix/manifest.scm --container --pure --no-grafts --no-substitutes
```
We don't include `make -C depends -j"$(nproc)" download` inside `contrib/guix/build.sh` because `contrib/guix/build.sh` is run inside the container, which has no network access (which is a good thing).

Here's what `ldd src/bitcoind` looks like when built in a Guix container:
```
linux-vdso.so.1 (0x00007ffcc2d90000)
libdl.so.2 => /gnu/store/h90vnqw0nwd0hhm1l5dgxsdrigddfmq4-glibc-2.28/lib/libdl.so.2 (0x00007fb7eda09000)

```
And here's what it looks in one of our releases:
```

/lib64/ld-linux-x86-64.so.2 => /usr/lib64/ld-linux-x86-64.so.2 (0x00007f8773392000)
```
~~I suspect it is because my script does not apply the gitian-input patches [described in the release process](https://github.com/bitcoin/bitcoin/blob/master/doc/release-process.md#fetch-and-create-inputs-first-time-or-when-dependency-versions-change) but there is no description as to how these patches are applied.~~ It might also be something else entirely.
Edit: It is something else. It appears that the gitian inputs are only used by [`gitian-win-signer.yml`](https://github.com/bitcoin/bitcoin/blob/d6e700e40f861ddd6743f4d13f0d6f6bc19093c2/contrib/gitian-descriptors/gitian-win-signer.yml#L14)

### Guix Introduction
This PR enables building bitcoin in Guix containers. [Guix](https://www.gnu.org/software/guix/manual/en/html_node/Features.html) is a transactional package manager much like Nix, but unlike Nix, it has more of a focus on [bootstrappability](https://www.gnu.org/software/guix/manual/en/html_node/Bootstrapping.html) and [reproducibility](https://www.gnu.org/software/guix/blog/tags/reproducible-builds/) which are attractive for security-sensitive projects like bitcoin.
### Guix Build Walkthrough
Please read the `README.md`.

<summary>Old instructions no. 1</summary>
In this PR, we define a Guix [manifest](https://www.gnu.org/software/guix/manual/en/html_node/Invoking-guix-package.html#profile_002dmanifest) in `contrib/guix/manifest.scm`, which declares what packages we want in our environment.
We can then invoke
```
guix environment --manifest=contrib/guix/manifest.scm --container --pure --no-grafts --no-substitutes
```
To have Guix:
1. Build an environment containing the packages we defined in our `contrib/guix/manifest.scm` manifest from the Guix bootstrap binaries (see [bootstrappability](https://www.gnu.org/software/guix/manual/en/html_node/Bootstrapping.html) for more details).
2. Start a container with that environment that has no network access, and no access to the host's filesystem except to the `pwd` that it was started in.
3. Drop you into a shell in that container.
> Note: if you don't want to wait hours for Guix to build the entire world from scratch, you can eliminate the `--no-substitutes` option to have Guix download from available binary sources. Note that this convenience doesn't necessarily compromise your security, as you can check that a package was built correctly after the fact using `guix build --check <packagename>`
Therefore, we can perform a build of bitcoin much like in Gitian by invoking the following:
```
make -C depends -j"$(nproc)" download && \
cat contrib/guix/build.sh | guix environment --manifest=contrib/guix/manifest.scm --container --pure --no-grafts --no-substitutes
```
We don't include `make -C depends -j"$(nproc)" download` inside `contrib/guix/build.sh` because `contrib/guix/build.sh` is run inside the container, which has no network access (which is a good thing).
</details>
### Rationale
I believe that this represents a substantial improvement for the "supply chain security" of bitcoin because:
1. We no longer have to rely on Ubuntu for our build environment for our releases ([oh the horror](https://github.com/bitcoin/bitcoin/blob/72bd4ab867e3be0d8410403d9641c08288d343e3/contrib/gitian-descriptors/gitian-linux.yml#L10)), because Guix builds everything about the container, we can perform this on almost any Linux distro/system.
2. It is now much easier to determine what trusted binaries are in our supply chain, and even make a nice visualization! (see [bootstrappability](https://www.gnu.org/software/guix/manual/en/html_node/Bootstrapping.html)).
3. There is active effort among Guix folks to minimize the number of trusted binaries even further. OriansJ's [stage0](https://github.com/oriansj/stage0), and janneke's [Mes](https://www.gnu.org/software/mes/) all aim to achieve [reduced binary boostrap](http://joyofsource.com/reduced-binary-seed-bootstrap.html) for Guix. In fact, I believe if OriansJ gets his way, we will end up some day with only a single trusted binary: hex0 (a ~500 byte self-hosting hex assembler).
### Steps to Completion

As of now, the command described above to perform a build of bitcoin a lot like Gitian works, but fails at the `check-symbols` stage. This is because a few dynamic libraries are linked in that shouldn't be.
Here's what `ldd src/bitcoind` looks like when built in a Guix container:
```

### Guix Introduction
This PR enables building bitcoin in Guix containers. [Guix](https://www.gnu.org/software/guix/manual/en/html_node/Features.html) is a transactional package manager much like Nix, but unlike Nix, it has more of a focus on [bootstrappability](https://www.gnu.org/software/guix/manual/en/html_node/Bootstrapping.html) and [reproducibility](https://www.gnu.org/software/guix/blog/tags/reproducible-builds/) which are attractive for security-sensitive projects like bitcoin.
### Guix Build Walkthrough
Please read the `README.md`.

<details>
<summary>Old instructions no. 1</summary>
In this PR, we define a Guix [manifest](https://www.gnu.org/software/guix/manual/en/html_node/Invoking-guix-package.html#profile_002dmanifest) in `contrib/guix/manifest.scm`, which declares what packages we want in our environment.
We can then invoke
```
guix environment --manifest=contrib/guix/manifest.scm --container --pure --no-grafts --no-substitutes
```
To have Guix:
1. Build an environment containing the packages we defined in our `contrib/guix/manifest.scm` manifest from the Guix bootstrap binaries (see [bootstrappability](https://www.gnu.org/software/guix/manual/en/html_node/Bootstrapping.html) for more details).
2. Start a container with that environment that has no network access, and no access to the host's filesystem except to the `pwd` that it was started in.
3. Drop you into a shell in that container.
> Note: if you don't want to wait hours for Guix to build the entire world from scratch, you can eliminate the `--no-substitutes` option to have Guix download from available binary sources. Note that this convenience doesn't necessarily compromise your security, as you can check that a package was built correctly after the fact using `guix build --check <packagename>`
Therefore, we can perform a build of bitcoin much like in Gitian by invoking the following:
```
make -C depends -j"$(nproc)" download && \
cat contrib/guix/build.sh | guix environment --manifest=contrib/guix/manifest.scm --container --pure --no-grafts --no-substitutes
```
We don't include `make -C depends -j"$(nproc)" download` inside `contrib/guix/build.sh` because `contrib/guix/build.sh` is run inside the container, which has no network access (which is a good thing).
</details>
### Rationale
I believe that this represents a substantial improvement for the "supply chain security" of bitcoin because:
1. We no longer have to rely on Ubuntu for our build environment for our releases ([oh the horror](https://github.com/bitcoin/bitcoin/blob/72bd4ab867e3be0d8410403d9641c08288d343e3/contrib/gitian-descriptors/gitian-linux.yml#L10)), because Guix builds everything about the container, we can perform this on almost any Linux distro/system.
2. It is now much easier to determine what trusted binaries are in our supply chain, and even make a nice visualization! (see [bootstrappability](https://www.gnu.org/software/guix/manual/en/html_node/Bootstrapping.html)).
3. There is active effort among Guix folks to minimize the number of trusted binaries even further. OriansJ's [stage0](https://github.com/oriansj/stage0), and janneke's [Mes](https://www.gnu.org/software/mes/) all aim to achieve [reduced binary boostrap](http://joyofsource.com/reduced-binary-seed-bootstrap.html) for Guix. In fact, I believe if OriansJ gets his way, we will end up some day with only a single trusted binary: hex0 (a ~500 byte self-hosting hex assembler).
### Steps to Completion
- [x] Successfully build bitcoin inside the Guix environment
- [x] Make `check-symbols` pass
- [x] Do the above but without nasty hacks
- [x] Solve some of the more innocuous hacks
- [ ] Make it cross-compile (HELP WANTED HERE)
- [x] Linux
- [x] x86_64-linux-gnu
- [x] i686-linux-gnu
- [x] aarch64-linux-gnu
- [x] arm-linux-gnueabihf
- [x] riscv64-linux-gnu
- [ ] OS X
- [ ] x86_64-apple-darwin14
- [ ] Windows
- [ ] x86_64-w64-mingw32
- [ ] Maybe make importer for depends syntax
- [ ] Document build process for future releases
- [ ] Extra: Pin the revision of Guix that we build with with Guix [inferiors](https://www.gnu.org/software/guix/manual/en/html_node/Inferiors.html)

As of now, the command described above to perform a build of bitcoin a lot like Gitian works, but fails at the `check-symbols` stage. This is because a few dynamic libraries are linked in that shouldn't be.
Here's what `ldd src/bitcoind` looks like when built in a Guix container:
```

### Guix Introduction
This PR enables building bitcoin in Guix containers. [Guix](https://www.gnu.org/software/guix/manual/en/html_node/Features.html) is a transactional package manager much like Nix, but unlike Nix, it has more of a focus on [bootstrappability](https://www.gnu.org/software/guix/manual/en/html_node/Bootstrapping.html) and [reproducibility](https://www.gnu.org/software/guix/blog/tags/reproducible-builds/) which are attractive for security-sensitive projects like bitcoin.
### Guix Build Walkthrough
Please read the `README.md`.

<details>
<summary>Old instructions no. 1</summary>
In this PR, we define a Guix [manifest](https://www.gnu.org/software/guix/manual/en/html_node/Invoking-guix-package.html#profile_002dmanifest) in `contrib/guix/manifest.scm`, which declares what packages we want in our environment.
We can then invoke
```
guix environment --manifest=contrib/guix/manifest.scm --container --pure --no-grafts --no-substitutes
```
To have Guix:
1. Build an environment containing the packages we defined in our `contrib/guix/manifest.scm` manifest from the Guix bootstrap binaries (see [bootstrappability](https://www.gnu.org/software/guix/manual/en/html_node/Bootstrapping.html) for more details).
2. Start a container with that environment that has no network access, and no access to the host's filesystem except to the `pwd` that it was started in.
3. Drop you into a shell in that container.
> Note: if you don't want to wait hours for Guix to build the entire world from scratch, you can eliminate the `--no-substitutes` option to have Guix download from available binary sources. Note that this convenience doesn't necessarily compromise your security, as you can check that a package was built correctly after the fact using `guix build --check <packagename>`
Therefore, we can perform a build of bitcoin much like in Gitian by invoking the following:
```
make -C depends -j"$(nproc)" download && \
cat contrib/guix/build.sh | guix environment --manifest=contrib/guix/manifest.scm --container --pure --no-grafts --no-substitutes
```
We don't include `make -C depends -j"$(nproc)" download` inside `contrib/guix/build.sh` because `contrib/guix/build.sh` is run inside the container, which has no network access (which is a good thing).
</details>
### Rationale
I believe that this represents a substantial improvement for the "supply chain security" of bitcoin because:
1. We no longer have to rely on Ubuntu for our build environment for our releases ([oh the horror](https://github.com/bitcoin/bitcoin/blob/72bd4ab867e3be0d8410403d9641c08288d343e3/contrib/gitian-descriptors/gitian-linux.yml#L10)), because Guix builds everything about the container, we can perform this on almost any Linux distro/system.
2. It is now much easier to determine what trusted binaries are in our supply chain, and even make a nice visualization! (see [bootstrappability](https://www.gnu.org/software/guix/manual/en/html_node/Bootstrapping.html)).
3. There is active effort among Guix folks to minimize the number of trusted binaries even further. OriansJ's [stage0](https://github.com/oriansj/stage0), and janneke's [Mes](https://www.gnu.org/software/mes/) all aim to achieve [reduced binary boostrap](http://joyofsource.com/reduced-binary-seed-bootstrap.html) for Guix. In fact, I believe if OriansJ gets his way, we will end up some day with only a single trusted binary: hex0 (a ~500 byte self-hosting hex assembler).
### Steps to Completion
- [x] Successfully build bitcoin inside the Guix environment
- [x] Make `check-symbols` pass
- [x] Do the above but without nasty hacks
- [x] Solve some of the more innocuous hacks
- [ ] Make it cross-compile (HELP WANTED HERE)
- [x] Linux
- [x] x86_64-linux-gnu
- [x] i686-linux-gnu
- [x] aarch64-linux-gnu
- [x] arm-linux-gnueabihf
- [x] riscv64-linux-gnu
- [ ] OS X
- [ ] x86_64-apple-darwin14
- [ ] Windows
- [ ] x86_64-w64-mingw32
- [ ] Maybe make importer for depends syntax
- [ ] Document build process for future releases
- [ ] Extra: Pin the revision of Guix that we build with with Guix [inferiors](https://www.gnu.org/software/guix/manual/en/html_node/Inferiors.html)

As of now, the command described above to perform a build of bitcoin a lot like Gitian works, but fails at the `check-symbols` stage. This is because a few dynamic libraries are linked in that shouldn't be.
Here's what `ldd src/bitcoind` looks like when built in a Guix container:
```
linux-vdso.so.1 (0x00007ffcc2d90000)
libdl.so.2 => /gnu/store/h90vnqw0nwd0hhm1l5dgxsdrigddfmq4-glibc-2.28/lib/libdl.so.2 (0x00007fb7eda09000)
librt.so.1 => /gnu/store/h90vnqw0nwd0hhm1l5dgxsdrigddfmq4-glibc-2.28/lib/librt.so.1 (0x00007fb7ed9ff000)
libstdc++.so.6 => /gnu/store/4sqps8dczv3g7rwbdibfz6rf5jlk7w90-gcc-5.5.0-lib/lib/libstdc++.so.6 (0x00007fb7ed87c000)
libpthread.so.0 => /gnu/store/h90vnqw0nwd0hhm1l5dgxsdrigddfmq4-glibc-2.28/lib/libpthread.so.0 (0x00007fb7ed85b000)
libm.so.6 => /gnu/store/h90vnqw0nwd0hhm1l5dgxsdrigddfmq4-glibc-2.28/lib/libm.so.6 (0x00007fb7ed6da000)
libgcc_s.so.1 => /gnu/store/4sqps8dczv3g7rwbdibfz6rf5jlk7w90-gcc-5.5.0-lib/lib/libgcc_s.so.1 (0x00007fb7ed6bf000)
libc.so.6 => /gnu/store/h90vnqw0nwd0hhm1l5dgxsdrigddfmq4-glibc-2.28/lib/libc.so.6 (0x00007fb7ed506000)
/gnu/store/h90vnqw0nwd0hhm1l5dgxsdrigddfmq4-glibc-2.28/lib/ld-linux-x86-64.so.2 => /usr/lib64/ld-linux-x86-64.so.2 (0x00007fb7ee3a0000)
```
And here's what it looks in one of our releases:
```
linux-vdso.so.1 (0x00007ffff52cd000)
libpthread.so.0 => /usr/lib/libpthread.so.0 (0x00007f87726b4000)
librt.so.1 => /usr/lib/librt.so.1 (0x00007f87726aa000)
libm.so.6 => /usr/lib/libm.so.6 (0x00007f8772525000)
libgcc_s.so.1 => /usr/lib/libgcc_s.so.1 (0x00007f877250b000)
libc.so.6 => /usr/lib/libc.so.6 (0x00007f8772347000)
/lib64/ld-linux-x86-64.so.2 => /usr/lib64/ld-linux-x86-64.so.2 (0x00007f8773392000)
```
~~I suspect it is because my script does not apply the gitian-input patches [described in the release process](https://github.com/bitcoin/bitcoin/blob/master/doc/release-process.md#fetch-and-create-inputs-first-time-or-when-dependency-versions-change) but there is no description as to how these patches are applied.~~ It might also be something else entirely.
Edit: It is something else. It appears that the gitian inputs are only used by [`gitian-win-signer.yml`](https://github.com/bitcoin/bitcoin/blob/d6e700e40f861ddd6743f4d13f0d6f6bc19093c2/contrib/gitian-descriptors/gitian-win-signer.yml#L14)
