Cory Fields b5f374fef7 qt: fix build with zlib for target This contains a few hacks very specific to Qt's buildsystem. These can be reverted once we split the build between native and target builds. Qt's build contains a circular dependency when not using a system zlib. By far the easiest fix is to switch to a system zlib, rather than Qt's own. However, that confuses Qt's cross build which assumes that when using a system zlib, it should also find a system (native) zlib for native tools. The build breaks if that zlib is not present. To solve this: 1. Always use a system zlib rather than the one provided by qt 2. Set force_bootstrap, which instructs the build tools to be built as though we're cross-compiling (build != target) 3. For build tools, use qt's internal zlib so that a native zlib is not required. Step 3 means that if any zlib headers are found by the native build, it will confuse Qt's internal zlib build. So we also need to make sure that the target headers/libs aren't found. To do so, specify that our cflags/cxxflags/cppflags/ldflags only apply for non-host builds.		8 years ago

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
