Merge #18743: depends: Add --sysroot option to mac os native compile flags 
1e94a2bcbc5ff8ae61eed9f31317ea534649116d depends: Add --sysroot option to mac os native compile flags (Russell Yanofsky)

Pull request description:

  Catalina SDK clang stopped automatically searching the SDK include paths when invoked without `--sysroot`:

  - https://github.com/bitcoin/bitcoin/pull/16367#issuecomment-594600985
  - https://github.com/Homebrew/homebrew-core/issues/45061

  This hasn't been a problem for current native depends packages because are passing their own `--sysroot` values, and hasn't been a problem for current host packages because they use `darwin_` commands instead of `build_darwin_` commands.  But the current `build_darwin_CC` and `build_darwin_CXX` commands are still unnecessarily fragile, and incompatible with new native depends packages added in https://github.com/bitcoin/bitcoin/pull/18677.

  Cory Fields (theuni) suggested in https://github.com/bitcoin/bitcoin/pull/16367#issuecomment-595393546 switching compiler from SDK clang to native clang (from $PATH) to avoid this problem. This is easy and makes a certain amount of sense for building native packages, as opposed to host packages. But Michael (fanquake) pointed out in https://github.com/bitcoin/bitcoin/pull/18677#discussion_r409934309 that it would be inconsistent to switch to non-SDK compilers while still using other SDK tools like `ranlib` and `install_name_tool`. So simplest, minimal fix seems to be just adding the missing `--sysroot` option.

    > ACK [1e94a2b](1e94a2bcbc) - I think this change is ok, and I prefer it to the previous patch.

    ACK 1e94a2bcbc5ff8ae61eed9f31317ea534649116d - I think this change is ok, and I prefer it to the previous patch. Thanks for the summary in the PR description. I played around with Xcode and the CLT; I think previously I didn't fully grok the slight differences between the two.

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:

  • i686-w64-mingw32 for Win32
  • x86_64-w64-mingw32 for Win64
  • x86_64-apple-darwin14 for macOS
  • arm-linux-gnueabihf for Linux ARM 32 bit
  • aarch64-linux-gnu for Linux ARM 64 bit
  • riscv32-linux-gnu for Linux RISC-V 32 bit
  • riscv64-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 python-setuptools

For Win32/Win64 cross compilation:

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

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
