Qt's configure grabs the path to xkb's data root during configure, but the build changes in 5.8 apparently broke the handling for cross builds. As a result, the string embedded in the binary depends on whether or not some files are present in the builder's filesystem. The "-xkb-config-root" configure setting is intended to allow manual overriding but it is also broken. See: https://bugreports.qt.io/browse/QTBUG-60005 This has since been fixed upstream, so just hard-code the path for now. We can drop this patch when we bump to a fixed Qt. Also, fix the "-qt-xkbcommon-x11" config param which was renamed. This does not appear to affect build results, presumably because auto-detection is working, but it does not hurt to be explicit.
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-darwin14for macOSarm-linux-gnueabihffor Linux ARM 32 bitaarch64-linux-gnufor 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
