[cairo] crosscompiling cairo with mingw64

[Maarten Bosmans]

It's really not that difficult. Can you describe more precisely what
problems you're encountering?

You should also compile the dependencies with the same toolchain. From
the top of my head the minimal set is pixman, libpng, zlib.

The configure script should take care of it all (however, I think the
libpng and zlib scripts aren't autotools based, so crosscompiling
could be a bit more difficult). The main trick is to keep the
cross-compilation toolchain and build software separate from the build
host's binaries.

This is the script I use to run configure in a source tree. It sets
all the variables needed for mingw cross-compilation.

echo "lt_cv_deplibs_check_method='pass_all'" >> mingw32.cache
PKG_CONFIG_LIBDIR=/usr/local/mingw/lib/pkgconfig/ \
CFLAGS=-I/usr/local/mingw/include                 \
CPPFLAGS=-I/usr/local/mingw/include               \
LDFLAGS=-L/usr/local/mingw/lib                    \
./configure \
  --disable-static --enable-shared \
  --host=i586-mingw32msvc --build=i686-linux \
  --prefix=/usr/local/mingw --cache-file=mingw32.cache \
  $@

Obviously, you need to change the toolchain prefix given to --host to
your specific triplet. The *FLAGS pointing to /usr/local/mingw/* is a
bit of a hack, but needed for packages that don't support pkg-config
properly. Also note usage of PKG_CONFIG_LIBDIR instead of
PKG_CONFIG_PATH to avoid picking up packages from the build host.
