Merge bitcoin/bitcoin#23603: build: Fix x86_64 <-> arm64 cross-compiling for macOS 
19f3896c9a build: Fix x86_64 <-> arm64 cross-compiling for macOS (Hennadii Stepanov)

Pull request description:

  Currently, on master (111c3e06b3), dependencies are built for the build system architecture, not the provided host.

  On Intel-based macOS Big Sur 11.6.1 (20G224):
  ```
  % make -C depends HOST=arm64-apple-darwin20
  % lipo -info depends/arm64-apple-darwin20/lib/libsqlite3.a
  Non-fat file: depends/arm64-apple-darwin20/lib/libsqlite3.a is architecture: x86_64
  ```

  On M1-based macOS Monterey 12.0.1 (21A559) the `boost` package building fails with multiple errors like that:
  ```
  % make -C depends boost HOST=x86_64-apple-darwin19
  ...
  error: option 'cf-protection=return' cannot be specified on this target
  error: option 'cf-protection=branch' cannot be specified on this target
  2 errors generated.
  ```

  This PR allows to cross-compile as follows:
  - on Intel-based macOS Big Sur 11.6.1 (20G224):
  ```
  % make -C depends HOST=arm64-apple-darwin20
  % lipo -info depends/arm64-apple-darwin20/lib/libsqlite3.a
  Non-fat file: depends/arm64-apple-darwin20/lib/libsqlite3.a is architecture: arm64
  % CONFIG_SITE=$PWD/depends/arm64-apple-darwin20/share/config.site ./configure
  % make
  % lipo -info src/qt/bitcoin-qt
  Non-fat file: src/qt/bitcoin-qt is architecture: arm64
  ```

  - on M1-based macOS Monterey 12.0.1 (21A559):
  ```
  % make -C depends HOST=x86_64-apple-darwin19
  % CONFIG_SITE=$PWD/depends/x86_64-apple-darwin19/share/config.site ./configure
  % make
  % lipo -info src/qt/bitcoin-qt
  Non-fat file: src/qt/bitcoin-qt is architecture: x86_64
  ```

  No behavior change for other builder-host pairs.

  This is an alternative to bitcoin/bitcoin#22506.

  fanquake:
    ACK 19f3896c9a - this is definitely cleaner than the approach in #22506. I've tested the x86_64 -> arm64 and arm64 -> x86_64 cross-compiles. Going to go-ahead and merge this given it's scoped to building for darwin targets, on darwin. Not sure if this is something we'll actually see used very often.

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

Bitcoin 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-triplets for cross compilation are:

  • i686-pc-linux-gnu for Linux 32 bit
  • x86_64-pc-linux-gnu for x86 Linux
  • x86_64-w64-mingw32 for Win64
  • x86_64-apple-darwin for macOS
  • arm-linux-gnueabihf for Linux ARM 32 bit
  • aarch64-linux-gnu for Linux ARM 64 bit
  • powerpc64-linux-gnu for Linux POWER 64-bit (big endian)
  • powerpc64le-linux-gnu for Linux POWER 64-bit (little endian)
  • riscv32-linux-gnu for Linux RISC-V 32 bit
  • riscv64-linux-gnu for Linux RISC-V 64 bit
  • s390x-linux-gnu for Linux S390X
  • armv7a-linux-android for Android ARM 32 bit
  • aarch64-linux-android for Android ARM 64 bit
  • i686-linux-android for Android x86 32 bit
  • x86_64-linux-android for Android x86 64 bit

The paths are automatically configured and no other options are needed unless targeting Android.

Install the required dependencies: Ubuntu & Debian

For macOS cross compilation

sudo apt-get install curl librsvg2-bin libtiff-tools bsdmainutils cmake imagemagick libz-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

For linux (including i386, ARM) cross compilation

Common linux dependencies:

sudo apt-get install make automake cmake 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_bitcoin 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

Dependency Options

The following can be set when running make: make FOO=bar

  • SOURCES_PATH: Downloaded sources will be placed here
  • BASE_CACHE: Built packages will be placed here
  • SDK_PATH: Path where SDKs can be found (used by macOS)
  • FALLBACK_DOWNLOAD_PATH: If a source file can't be fetched, try here before giving up
  • NO_QT: Don't download/build/cache Qt and its dependencies
  • NO_QR: Don't download/build/cache packages needed for enabling qrencode
  • NO_ZMQ: Don't download/build/cache packages needed for enabling ZeroMQ
  • NO_WALLET: Don't download/build/cache libs needed to enable the wallet
  • NO_BDB: Don't download/build/cache BerkeleyDB
  • NO_SQLITE: Don't download/build/cache SQLite
  • NO_UPNP: Don't download/build/cache packages needed for enabling UPnP
  • NO_NATPMP: Don't download/build/cache packages needed for enabling NAT-PMP
  • ALLOW_HOST_PACKAGES: Packages that are missed in dependencies (due to NO_* option or build script logic) are searched for among the host system packages using pkg-config. It allows building with packages of other (newer) versions
  • MULTIPROCESS: Build libmultiprocess (experimental, requires CMake)
  • DEBUG: Disable some optimizations and enable more runtime checking
  • HOST_ID_SALT: Optional salt to use when generating host package ids
  • BUILD_ID_SALT: Optional salt to use when generating build package ids
  • FORCE_USE_SYSTEM_CLANG: (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 bitcoin's configure. In this case, --disable-wallet.
