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 Bitcoin's configure. In the above example, a 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-w64-mingw32 for Win32
• x86_64-w64-mingw32 for Win64
• x86_64-apple-darwin11 for MacOSX
• arm-linux-gnueabihf for Linux ARM

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

If some packages are not built, for example make NO_WALLET=1, the appropriate options will be passed to dash'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
