Even though [some concerns were raised](https://github.com/bitcoin/bitcoin/issues/16684#issuecomment-726214696) in #16684 with regard to `std::shared_mutex` being unsafe to use across some glibc versions, I still think this change is an improvement. As I mentioned in #21022, I also think trying to restrict standard library feature usage based on bugs in glibc is not only hard to do, but it's not currently clear exactly how we do that in practice (does it also extend to patching out use in our dependencies, should we be implementing more runtime checks for features we are using, when do we consider an affected glibc "old enough" not to worry about? etc). If you take a look through the [glibc bug tracker](https://sourceware.org/bugzilla/describecomponents.cgi?product=glibc) you'll no doubt find plenty of (active) bug reports for standard library code we already using. Obviously not to say we shouldn't try and avoid buggy code where possible. Two other points: [Cory mentioned in #21022](https://github.com/bitcoin/bitcoin/pull/21022#issuecomment-769274179): > It also seems reasonable to me to worry that boost hits the same underlying glibc bug, and we've just not happened to trigger the right conditions yet. Moving away from Boost to the standard library also removes the potential for differences related to Boosts configuration. Boost has multiple versions of `shared_mutex`, and what you end up using, and what it's backed by depends on: * The version of Boost. * The platform you're building for. * Which version of `BOOST_THREAD_VERSION` is defined: (2,3,4 or 5) default=2. (see [here](https://www.boost.org/doc/libs/1_70_0/doc/html/thread/build.html#thread.build.configuration) for some of the differences). * Is `BOOST_THREAD_V2_SHARED_MUTEX` defined? (not by default). If so, you might get the ["less performant, but more robust"](https://github.com/boostorg/thread/issues/230#issuecomment-475937761) version of `shared_mutex`. A lot of these factors are eliminated by our use of depends, but users will have varying configurations. It's also not inconceivable to think that a distro, or some package manager might start defining something like `BOOST_THREAD_VERSION=3`. Boost tried to change the default from 2 to 3 at one point. With this change, we no longer use Boost Thread, so this PR also removes it from depends, the build system, CI etc. Previous similar PRs were #19183 & #20922. The authors are included in the commits here. Also related to #21022 - pthread sanity checking.

Usage
To build dependencies for the current arch+OS:
make
To build for another arch/OS:
make HOST=host-platform-triplet
For example:
make HOST=x86_64-w64-mingw32 -j4
Dash Core's configure
script by default will ignore the depends output. In
order for it to pick up libraries, tools, and settings from the depends build,
you must set the CONFIG_SITE
environment variable to point to a config.site
settings file.
In the above example, a file named depends/x86_64-w64-mingw32/share/config.site
will be
created. To use it during compilation:
CONFIG_SITE=$PWD/depends/x86_64-w64-mingw32/share/config.site ./configure
The default install prefix when using config.site
is --prefix=depends/<host-platform-triplet>
,
so depends build outputs will be installed in that location.
Common host-platform-triplet
s for cross compilation are:

Install the required dependencies: Ubuntu & Debian
For macOS cross compilation
sudo apt-get install curl bsdmainutils cmake libcap-dev libz-dev libbz2-dev python3-setuptools libtinfo5 xorriso
Note: You must obtain the macOS SDK before proceeding with a cross-compile.
Under the depends directory, create a subdirectory named SDKs
.
Then, place the extracted SDK under this new directory.
For more information, see SDK Extraction.
For Win64 cross compilation
- see build-windows.md
For linux (including i386, ARM) cross compilation
Common linux dependencies:
sudo apt-get install make automake curl g++-multilib libtool binutils-gold bsdmainutils pkg-config python3 patch bison
For linux ARM cross compilation:
sudo apt-get install g++-arm-linux-gnueabihf binutils-arm-linux-gnueabihf
For linux AARCH64 cross compilation:
sudo apt-get install g++-aarch64-linux-gnu binutils-aarch64-linux-gnu
For linux POWER 64-bit cross compilation (there are no packages for 32-bit):
sudo apt-get install g++-powerpc64-linux-gnu binutils-powerpc64-linux-gnu g++-powerpc64le-linux-gnu binutils-powerpc64le-linux-gnu
For linux RISC-V 64-bit cross compilation (there are no packages for 32-bit):
sudo apt-get install g++-riscv64-linux-gnu binutils-riscv64-linux-gnu
RISC-V known issue: gcc-7.3.0 and gcc-7.3.1 result in a broken test_dash
executable (see https://github.com/bitcoin/bitcoin/pull/13543),
this is apparently fixed in gcc-8.1.0.
For linux S390X cross compilation:
sudo apt-get install g++-s390x-linux-gnu binutils-s390x-linux-gnu
Install the required dependencies: OpenBSD
pkg_add bash gtar

: (EXPERTS ONLY) When cross-compiling for macOS, use Clang found in the system's$PATH
rather than the default prebuilt release of Clang from llvm.org. Clang 8 or later is required.
If some packages are not built, for example make NO_WALLET=1
, the appropriate
options will be passed to Dash Core's configure. In this case, --disable-wallet
.
Additional targets
download: run 'make download' to fetch all sources without building them
download-osx: run 'make download-osx' to fetch all sources needed for macOS builds
download-win: run 'make download-win' to fetch all sources needed for win builds
download-linux: run 'make download-linux' to fetch all sources needed for linux builds
Android
Before proceeding with an Android build one needs to get the Android SDK and use the "SDK Manager" tool to download the NDK and one or more "Platform packages" (these are Android versions and have a corresponding API level).
In order to build ANDROID_API_LEVEL
(API level corresponding to the Android version targeted, e.g. Android 9.0 Pie is 28 and its "Platform package" needs to be available) and ANDROID_TOOLCHAIN_BIN
(path to toolchain binaries depending on the platform the build is being performed on) need to be set.
API levels from 24 to 29 have been tested to work.
If the build includes Qt, environment variables ANDROID_SDK
and ANDROID_NDK
need to be set as well but can otherwise be omitted.
This is an example command for a default build with no disabled dependencies:
ANDROID_SDK=/home/user/Android/Sdk ANDROID_NDK=/home/user/Android/Sdk/ndk-bundle make HOST=aarch64-linux-android ANDROID_API_LEVEL=28 ANDROID_TOOLCHAIN_BIN=/home/user/Android/Sdk/ndk-bundle/toolchains/llvm/prebuilt/linux-x86_64/bin
