To build dependencies for the current arch+OS:
To build for another arch/OS:
make HOST=x86_64-w64-mingw32 -j4
A prefix will be generated that's suitable for plugging into Bitcoin's configure. In the above example, a dir named x86_64-w64-mingw32 will be created. To use it for Bitcoin:
Common host-platform-triplets for cross compilation are:
i686-w64-mingw32 for Win32 x86_64-w64-mingw32 for Win64 x86_64-apple-darwin11 for MacOSX arm-linux-gnueabihf for Linux ARM 32 bit aarch64-linux-gnu for Linux ARM 64 bit
No other options are needed, the paths are automatically configured.
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 OSX) 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 bitcoin's configure. In this case, --disable-wallet.
download: run 'make download' to fetch all sources without building them download-osx: run 'make download-osx' to fetch all sources needed for osx 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
