So I've been looking around for people who have built shared libraries on
windows and have run in to a bit of a stumbling block. I'm able to compile
without the BUILD_SHARED_LIBS flag but if I put turn the flag on as follows:
cmake -G "MinGW Makefiles" -DCMAKE_BUILD_TYPE:STRING=Release
-DBUILD_SHARED_LIBS:BOOL=ON ../llvm-2.7
Then call:
mingw32-make
I get:
...

This should work unless it involves constant data structures referencing

Any help would be greatly appreciated.
btw: my MinGW gcc is version 4.5.0.
Thanks,
