### 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 **Moneyrocket 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/`, so depends build outputs will be installed in that location. Common `host-platform-triplet`s 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 - `arm64-apple-darwin` for ARM 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 - `x86_64-linux-android` for Android x86 64 bit The paths are automatically configured and no other options are needed unless targeting [Android](../doc/build-android.md). ### Install the required dependencies: Ubuntu & Debian #### For macOS cross compilation sudo apt-get install curl bsdmainutils cmake 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](../contrib/macdeploy/README.md#sdk-extraction). #### For Win64 cross compilation - see [build-windows.md](../doc/build-windows.md#cross-compilation-for-ubuntu-and-windows-subsystem-for-linux) #### For linux (including i386, ARM) cross compilation Common linux dependencies: sudo apt-get install make automake cmake curl g++-multilib libtool binutils 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 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 ### 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 - `C_STANDARD`: Set the C standard version used. Defaults to `c11`. - `CXX_STANDARD`: Set the C++ standard version used. Defaults to `c++17`. - `NO_BOOST`: Don't download/build/cache Boost - `NO_LIBEVENT`: Don't download/build/cache Libevent - `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 - `LOG`: Use file-based logging for individual packages. During a package build its log file resides in the `depends` directory, and the log file is printed out automatically in case of build error. After successful build log files are moved along with package archives - `LTO`: Use LTO when building packages. If some packages are not built, for example `make NO_WALLET=1`, the appropriate options will be passed to moneyrocket'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 ### Other documentation - [description.md](description.md): General description of the depends system - [packages.md](packages.md): Steps for adding packages
