Prerequisites

The depends system is maintained and tested using Ubuntu Bionic. Both generic apt packages, and packages specific to the target architecture are required to successfully compile all dependencies. Listed packages are tested and known to work.

Generic packages

sudo apt-get install autoconf automake binutils-gold ca-certificates curl \
                     faketime git-core libtool pkg-config python bison

Generic linux: i686-pc-linux-gnu and x86_64-linux-gnu

sudo apt-get install g++-7-multilib gcc-7-multilib

ARM7 32bit: arm-linux-gnueabihf

sudo apt-get install g++-arm-linux-gnueabihf g++-7-arm-linux-gnueabihf \
                     gcc-7-arm-linux-gnueabihf binutils-arm-linux-gnueabihf

ARM 64bit: aarch64-linux-gnu

sudo apt-get install g++-aarch64-linux-gnu g++-7-aarch64-linux-gnu \
                     gcc-7-aarch64-linux-gnu binutils-aarch64-linux-gnu

Windows: i686-w64-mingw32 and x86_64-w64-mingw32

sudo apt-get install g++ g++-mingw-w64 mingw-w64 nsis zip

macOS (Intel): x86_64-apple-darwin11

sudo apt-get install g++ cmake imagemagick fonts-tuffy libz-dev libbz2-dev \
                     libcap-dev librsvg2-bin libtiff-tools python python-dev \
                     python-setuptools

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 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.

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
