e60ef21b8a0f62ebc2e0bdbb5943fa80cc4d98b2 doc: Clang 8 or later is required with FORCE_USE_SYSTEM_CLANG (fanquake) Pull request description: The usage of pragmas within the macOS SDK requires LLVM Clang 8. This is the same version as our prebuilt Clang, however the minimum is worth noting here as they may diverge and/or expert users might expect they could use an earlier version. If you compile depends using `FORCE_USE_SYSTEM_CLANG=1` and Clang 7 you'll see output like: ```bash In file included from kernel/qcore_mac_objc.mm:44: In file included from /bitcoin/depends/SDKs/Xcode-11.3.1-11C505-extracted-SDK-with-libcxx-headers/System/Library/Frameworks/AppKit.framework/Headers/NSText.h:9: In file included from /bitcoin/depends/SDKs/Xcode-11.3.1-11C505-extracted-SDK-with-libcxx-headers/System/Library/Frameworks/AppKit.framework/Headers/NSView.h:19: In file included from /bitcoin/depends/SDKs/Xcode-11.3.1-11C505-extracted-SDK-with-libcxx-headers/System/Library/Frameworks/AppKit.framework/Headers/NSResponder.h:10: /bitcoin/depends/SDKs/Xcode-11.3.1-11C505-extracted-SDK-with-libcxx-headers/System/Library/Frameworks/AppKit.framework/Headers/NSEvent.h:19:1: error: expected 'push' or 'pop' after '#pragma clang attribute' /bitcoin/depends/SDKs/Xcode-11.3.1-11C505-extracted-SDK-with-libcxx-headers/usr/include/os/availability.h:104:273: note: expanded from macro 'API_UNAVAILABLE_BEGIN' ...__API_UNAVAILABLE_BEGIN5, __API_UNAVAILABLE_BEGIN4, __API_UNAVAILABLE_BEGIN3, __API_UNAVAILABLE_BEGIN2, __API_UNAVAILABLE_BEGIN1, 0)(__VA_A... ^ fatal error: too many errors emitted, stopping now [-ferror-limit=] 20 errors generated. ``` I've got a [godbolt here](https://godbolt.org/z/j6r987) that contains a demo of the issue (based off the macOS SDK). It will compile with Clang 8 but not with Clang 7.

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
A prefix will be generated that's suitable for plugging into Dash's configure. In the above example, a dir named x86_64-w64-mingw32 will be created. To use it for Dash:
./configure --prefix=`pwd`/depends/x86_64-w64-mingw32
Common host-platform-triplets
for cross compilation are:
x86_64-w64-mingw32
for Win64x86_64-apple-darwin18
for macOSarm-linux-gnueabihf
for Linux ARM 32 bitaarch64-linux-gnu
for Linux ARM 64 bitriscv32-linux-gnu
for Linux RISC-V 32 bitriscv64-linux-gnu
for Linux RISC-V 64 bit
No other options are needed, the paths are automatically configured.
Install the required dependencies: Ubuntu & Debian
For macOS cross compilation:
sudo apt-get install curl librsvg2-bin libtiff-tools bsdmainutils imagemagick libcap-dev libz-dev libbz2-dev python3-setuptools libtinfo5
For Win64 cross compilation:
- see build-windows.md
For linux (including i386, ARM) cross compilation:
sudo apt-get install curl g++-aarch64-linux-gnu g++-4.8-aarch64-linux-gnu gcc-4.8-aarch64-linux-gnu binutils-aarch64-linux-gnu g++-arm-linux-gnueabihf g++-4.8-arm-linux-gnueabihf gcc-4.8-arm-linux-gnueabihf binutils-arm-linux-gnueabihf g++-4.8-multilib gcc-4.8-multilib binutils-gold bsdmainutils
For linux RISC-V 64-bit cross compilation (there are no packages for 32-bit):
sudo apt-get install curl 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.
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 sdk's 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_WALLET
- Don't download/build/cache libs needed to enable the wallet
- NO_UPNP
- Don't download/build/cache packages needed for enabling upnp
- 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.
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
