UNIX BUILD NOTES
2013-05-20 06:30:00 +02:00
====================
Some notes on how to build Dash Core in Unix.
(For BSD specific instructions, see `build-*bsd.md` in this directory.)
Note
---------------------
Always use absolute paths to configure and compile Dash Core and the dependencies.
For example, when specifying the path of the dependency:
2014-05-19 12:42:57 +02:00
```sh
../dist/configure --enable-cxx --disable-shared --with-pic --prefix=$BDB_PREFIX
```
Here `BDB_PREFIX` must be an absolute path - it is defined using $(pwd) which ensures
the usage of the absolute path.
To Build
---------------------
```sh
./autogen.sh
./configure
make
make install # optional
```
This will build dash-qt as well, if the dependencies are met.
Dependencies
---------------------
These dependencies are required:
Library | Purpose | Description
------------|------------------|----------------------
libboost | Utility | Library for threading, data structures, etc
libevent | Networking | OS independent asynchronous networking
Optional dependencies:
Library | Purpose | Description
------------|------------------|----------------------
gmp | Optimized math routines | Arbitrary precision arithmetic library
miniupnpc | UPnP Support | Firewall-jumping support
libnatpmp | NAT-PMP Support | Firewall-jumping support
libdb4.8 | Berkeley DB | Wallet storage (only needed when legacy wallet enabled)
qt | GUI | GUI toolkit (only needed when GUI enabled)
libqrencode | QR codes in GUI | QR code generation (only needed when GUI enabled)
libzmq3 | ZMQ notification | ZMQ notifications (requires ZMQ version >= 4.0.0)
sqlite3 | SQLite DB | Wallet storage (only needed when descriptor wallet enabled)
For the versions used, see [dependencies.md](dependencies.md)
Memory Requirements
--------------------
C++ compilers are memory-hungry. It is recommended to have at least 1.5 GB of
memory available when compiling Dash Core. On systems with less, gcc can be
tuned to conserve memory with additional CXXFLAGS:
```sh
./configure CXXFLAGS="--param ggc-min-expand=1 --param ggc-min-heapsize=32768"
```
## Linux Distribution Specific Instructions
### Ubuntu & Debian
#### Dependency Build Instructions
Build requirements:
```sh
sudo apt-get install build-essential libtool autotools-dev automake pkg-config bsdmainutils bison python3
```
Now, you can either build from self-compiled [depends](/depends/README.md) or install the required dependencies:
```sh
2024-08-07 10:06:27 +02:00
sudo apt-get install libevent-dev libboost-dev
```
SQLite is required for the descriptor wallet:
```sh
sudo apt-get install libsqlite3-dev
```
Berkeley DB is required for the legacy wallet. Ubuntu and Debian have their own `libdb-dev` and `libdb++-dev` packages,
but these will install Berkeley DB 5.1 or later. This will break binary wallet compatibility with the distributed
executables, which are based on BerkeleyDB 4.8. If you do not care about wallet compatibility, pass
`--with-incompatible-bdb` to configure. Otherwise, you can build Berkeley DB [yourself](#berkeley-db).
To build Dash Core without wallet, see [*Disable-wallet mode*](#disable-wallet-mode)

It's odd to me that we maintain configure-time options for setting the default port-forwarding runtime state (but no other similar options), and I'm not sure what use-case it satisfies, that can't be achieved by multiple other means. I also doubt that we'll ever restart using these in release builds, or turning on any of this by default. I think the only scenario these options would be used is when you want to compile your own binaries (we don't use them in Guix), with port-forwarding on by default, but otherwise can't or don't want to use a `.conf` file, can't or don't want to pass command line options at runtime, and also don't want to modify the source code?

Optional port mapping libraries (see: `--with-miniupnpc` and `--with-natpmp`):
```sh
sudo apt-get install libminiupnpc-dev libnatpmp-dev
```
ZMQ dependencies (provides ZMQ API):
```sh
sudo apt-get install libzmq3-dev
```
GMP dependencies (provides platform-optimized routines):
```sh
sudo apt-get install libgmp-dev
```
GUI dependencies:
If you want to build dash-qt, make sure that the required packages for Qt development
are installed. Qt 5 is necessary to build the GUI.
To build without GUI pass `--without-gui`.
To build with Qt 5 you need the following:
```sh
sudo apt-get install libqt5gui5 libqt5core5a libqt5dbus5 qttools5-dev qttools5-dev-tools
```

libqrencode (optional) can be installed with:
```sh
sudo apt-get install libqrencode-dev
```
Once these are installed, they will be found by configure and a dash-qt executable will be
built by default.
### Fedora
#### Dependency Build Instructions
Build requirements:
```sh
sudo dnf install gcc-c++ libtool make autoconf automake python3
```
Now, you can either build from self-compiled [depends](/depends/README.md) or install the required dependencies:
```sh
sudo dnf install libevent-devel boost-devel
```
SQLite is required for the descriptor wallet:
```sh
sudo dnf install sqlite-devel
```
Berkeley DB is required for the legacy wallet:
```sh
sudo dnf install libdb4-devel libdb4-cxx-devel
```
Newer Fedora releases, since Fedora 33, have only `libdb-devel` and `libdb-cxx-devel` packages, but these will install
Berkeley DB 5.3 or later. This will break binary wallet compatibility with the distributed executables, which
are based on Berkeley DB 4.8. If you do not care about wallet compatibility,
pass `--with-incompatible-bdb` to configure. Otherwise, you can build Berkeley DB [yourself](#berkeley-db).
To build Dash Core without wallet, see [*Disable-wallet mode*](#disable-wallet-mode)

libqrencode (optional) can be installed with:
```sh
sudo dnf install qrencode-devel
```
Once these are installed, they will be found by configure and a dash-qt executable will be
built by default.
Notes
-----
The release is built with GCC and then "strip dashd" to strip the debug
symbols, which reduces the executable size by about 90%.

turned off by default.
Berkeley DB
-----------
The legacy wallet uses Berkeley DB. To ensure backwards compatibility it is
recommended to use Berkeley DB 4.8. If you have to build it yourself, you can
use [the installation script included in contrib/](/contrib/install_db4.sh)
like so:
```sh
./contrib/install_db4.sh `pwd`
```
2013-05-20 06:30:00 +02:00
from the root of the repository.
Otherwise, you can build Dash Core from self-compiled [depends](/depends/README.md).
**Note**: You only need Berkeley DB if the wallet is enabled (see [*Disable-wallet mode*](#disable-wallet-mode)).
Security
--------
To help make your Dash Core installation more secure by making certain attacks impossible to
exploit even if a vulnerability is found, binaries are hardened by default.
This can be disabled with:
2013-12-09 11:08:08 +01:00
Hardening Flags:
./configure --enable-hardening
./configure --disable-hardening
Hardening enables the following features:
* _Position Independent Executable_: Build position independent code to take advantage of Address Space Layout Randomization
2015-04-28 16:48:28 +02:00
offered by some kernels. Attackers who can cause execution of code at an arbitrary memory
location are thwarted if they don't know where anything useful is located.
The stack and heap are randomly located by default, but this allows the code section to be
randomly located as well.
2015-04-28 16:48:28 +02:00
On an AMD64 processor where a library was not compiled with -fPIC, this will cause an error
such as: "relocation R_X86_64_32 against `......' can not be used when making a shared object;"
To test that you have built PIE executable, install scanelf, part of paxutils, and use:
2013-05-20 06:30:00 +02:00
scanelf -e ./dashd
The output should contain:
2015-11-04 13:22:45 +01:00
TYPE
ET_DYN
* _Non-executable Stack_: If the stack is executable then trivial stack-based buffer overflow exploits are possible if
vulnerable buffers are found. By default, Dash Core should be built with a non-executable stack,
but if one of the libraries it uses asks for an executable stack or someone makes a mistake
and uses a compiler extension which requires an executable stack, it will silently build an
executable without the non-executable stack protection.
To verify that the stack is non-executable after compiling use:
2015-05-22 05:10:13 +02:00
`scanelf -e ./dashd`
The output should contain:
STK/REL/PTL
RW- R-- RW-
The STK RW- means that the stack is readable and writeable but not executable.
Disable-wallet mode
--------------------
When the intention is to run only a P2P node without a wallet, Dash Core may be compiled in
disable-wallet mode with:
./configure --disable-wallet
In this case there is no dependency on Berkeley DB 4.8 and SQLite.
Mining is also possible in disable-wallet mode using the `getblocktemplate` RPC call.
Additional Configure Flags
--------------------------
A list of additional configure flags can be displayed with:
```sh
./configure --help
```
Setup and Build Example: Arch Linux
-----------------------------------
This example lists the steps necessary to setup and build a command line only, non-wallet distribution of the latest changes on Arch Linux:
```sh
pacman -S git base-devel boost libevent python
git clone https://github.com/dashpay/dash.git
cd dash/
./autogen.sh
./configure --disable-wallet --without-gui --without-miniupnpc
make check
```
Note:
Enabling wallet support requires either compiling against a Berkeley DB newer than 4.8 (package `db`) using `--with-incompatible-bdb`,
or building and depending on a local version of Berkeley DB 4.8. The readily available Arch Linux packages are currently built using
`--with-incompatible-bdb` according to the [PKGBUILD](https://projects.archlinux.org/svntogit/community.git/tree/bitcoin/trunk/PKGBUILD).
As mentioned above, when maintaining portability of the wallet between the standard Dash Core distributions and independently built
node software is desired, Berkeley DB 4.8 must be used.
