Usage

Step 1.

(These commands should be run in the depends folder)

To build dependencies for the current arch+OS run this:

make

If you want to build for another arch/OS you need to run this command:

make HOST=[host-platform-triplet]

For example:

make HOST=x86_64-w64-mingw32 -j4

Step 2.

  • A folder will be generated inside the depends folder by whichever command you ran.

  • This folder's path needs to be plugged into the configure command.

  • Using the above example, make HOST=x86_64-w64-mingw32 -j4 , a dir named x86_64-w64-mingw32 is generated. We would plug it into the depends command like this:

    # This command is run in the project's root folder, not in /depends or in /src
./configure --prefix=`pwd`/depends/x86_64-w64-mingw32 #this is in the root dir for the project, not in /depends

Common host-platform-triplets for cross compilation are:

These may differ depending on which version your operating system is on, for example the OSX folder generated will change depending on the exact OSX version

Operating System Prefix
Windows 32bit i686-w64-mingw32
Windows 64bit x86_64-w64-mingw32
Mac OSX x86_64-apple-darwin17.6.0
Linux ARM 32bit arm-linux-gnueabihf
Linux ARM 64bit aarch64-linux-gnu

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.

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 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
