(no subject)

hello,

i'm trying to cross-compile openal (git version) for win32 mingw.

openal-soft/build$ cmake .. -DCMAKE_TOOLCHAIN_FILE=../XCompile.txt
-DHOST=i586-mingw32msvc -DCMAKE_RC_COMPILER=i586-mingw32msvc-windres
openal-soft/build$ make
...

make[1]: *** [CMakeFiles/openal.dir/all] Error 2
make: *** [all] Error 2

i'm on debian wheezy and deb packages mingw32 4.2.1.dfsg-2,
mingw32-binutils 2.20-0.2, mingw32-runtime 3.13-1.

Please help.  I'd like to compile static library too - I don't have
experience with cmake - so don't know how to change XCompile.txt in
good way.
