Merge #20419: build: set minimum supported macOS to 10.14 
a52ecc936a build: set minimum supported macOS to 10.14 (fanquake)

Pull request description:

  This is a requirement for C++17 support. See my comments [here](https://github.com/bitcoin/bitcoin/issues/16684#issuecomment-643722538):

  > You cannot use std::get with std::variant on macOS < 10.14, because Apples libc++ doesn't support the std::bad_variant_access exception. [Relevant comment](https://github.com/bitcoin/bitcoin/pull/19183#discussion_r439794318) in #19183.

  > While we could work around this in our own code, using std::get_if, this would still be a problem for 3rd-party dependencies.

  > I've been testing Qt 5.15LTS (we'll have to enable C++17 in qt, and may upgrade to a newer version at the same time), and you can't enable -std c++17, while targeting a macOS deployment version < 10.14, configuring will fail. They are making use of std::get with std::variant throughout their cocoa code.

  We would have to had to have bumped to at least 10.13 in any case, as Qt 5.15 (#19716) [requires 10.13+](https://doc.qt.io/qt-5/supported-platforms.html).

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 point it at the appropriate --prefix directory generated by the build. In the above example, a prefix dir named x86_64-w64-mingw32 will be created. To use it for Bitcoin:

./configure --prefix=$PWD/depends/x86_64-w64-mingw32

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-darwin18 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 libcap-dev libz-dev libbz2-dev python3-setuptools libtinfo5

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

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 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_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
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.

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
