[llvm-dev] error in building llvm

Here is another strange error:

/home/marwayusuf/llvm-env/llvm/tools/clang/lib/Basic/VirtualFileSystem.cpp:332:10: error: redefinition of ‘struct llvm::DenseMapInfo<llvm::StringRef>’
   struct DenseMapInfo<StringRef> {

Hi,
If you don't actually need all these extra projects, you can edit the
CMakeCache.txt in the build directory to disable them.  Look for
LLVM_TOOL_XXX_BUILD and set the corresponding ones to OFF, for example:

LLVM_TOOL_LLDB_BUILD:BOOL=ON   // Set this to OFF to disable LLDB
