The patch for clang/lib/Serialization/CMakeLists.txt
Hi,
I've got the following link error (lots of lots of error messages) of the
shared library (libclangSerialization.dll):

Here's my CMake script:
cmake -DCMAKE_INSTALL_PREFIX:PATH=/mingw \
-DCMAKE_BUILD_TYPE=Release \
-DBUILD_SHARED_LIBS:BOOL=ON \
-DLLVM_TARGETS_TO_BUILD:STRING=X86 \
-G "MSYS Makefiles" \
../llvm-3.0.src
To fix the undefined reference to LLVM libraries all we need is to set
LLVM_LINK_COMPONENTS with the "support" component (i.e. libLLVMSupport).
But then, we still get huge number of undefined reference errors where
the linker is unable to link to, say libclangAST, etc.
With the attached patch, I finally managed to bring down the number of
undefined reference errors to the reasonable level:

At this point the missing library to be linked is libclangFrontend.
However, libclangFrontend depends on libclangSerialization as well,
resulting in the circular dependency.
How can we break this circular dependency between libclangFrontend and
libclangSerialization?
