[LLVMdev] CMake does not work with LLVM anymore?

[Sean Lee]

Hi,

I am just letting you know that I have not been able to build LLVM
using CMake since I ran svn up yesterday.
And it would be great if somebody could tell me whether the problem is
on my end.

What I did was,

~/llvm$ svn up

~/llvm$ mkdir cmakebuild

~/llvm$ cd cmakebuild

~/llvm/cmakebuild$ cmake -DCMAKE_BUILD_TYPE:STRING="Release"
-DLLVM_TARGETS_TO_BUILD:STRING="X86" ..
-- Target triple:
-- LLVM_HOSTTRIPLE: i686-pc-linux-gnu
-- Threads enabled.
-- Targeting X86
-- Target triple:
-- Configuring done
-- Generating done
-- Build files have been written to: /home/selee/llvm/cmakebuild

~/llvm/cmakebuild$ make

After awhile, I got the following error message and couldn't complete the build.

It seems that RWMutex has been added to the source tree yesterday, and
some source code files have been modified accordingly.

Thanks,
Sean
