- create a script to handle split debug. This will also eventually need to check targets, and use dsymutil for osx. - update config.guess/config.sub for bdb for aarch64. - temporarily disable symbol checks for arm/aarch64 - quit renaming to linux32/linux64 and use the host directly This also adds a hack to work around an Ubuntu bug in the gcc-multilib package: https://bugs.launchpad.net/ubuntu/+source/gcc-defaults-armhf-cross/+bug/1347820 The problem is that gcc-multilib conflicts with the aarch toolchain. gcc-multilib installs a symlink that points /usr/include/asm -> /usr/include/x86_64-linux-gnu/asm. Without this link, gcc -m32 can't find asm/errno.h (and others), since /usr/include/x86_64-linux-gnu isn't in its default include path. But /usr/include/i386-linux-gnu is (though it doesn't exist on disk). So work around the problem by linking /usr/include/i386-linux-gnu/asm -> /usr/include/x86_64-linux-gnu/asm. The symlink fix is actually quite reasonable, but echoing the password into sudo is nasty, and should probably be addressed in gitian itself. It makes more sense to enable passwordless sudo for the build user by default. |

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-mingw32for Win32x86_64-w64-mingw32for Win64x86_64-apple-darwin11for MacOSXarm-linux-gnueabihffor 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
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
