[llvm-dev] undefined symbols during linking LLDB 4.0 RC1

Hello, I update my building scripts to build LLVM 4.0 RC1 (with clang, lldb, libc++, libc++abi, lld) on CentOS 6 and I got a lot of undefined symbols during linking LLDB. 

I'm using clang-3.9 and this configuration:

-DLLVM_TARGETS_TO_BUILD="X86" 
-DCMAKE_BUILD_TYPE=Release 
-DCMAKE_C_COMPILER=/usr/bin/clang
-DCMAKE_CXX_COMPILER=/usr/bin/clang++
-DCMAKE_EXE_LINKER_FLAGS="-lc++abi -lc++" 
-DCMAKE_EXE_LINKER_FLAGS="-lc++abi -lc++" 
-DCMAKE_SHARED_LINKER_FLAGS="-lc++abi -lc++" 
-DCMAKE_MODULE_LINKER_FLAGS="-lc++abi -lc++" 
-DLLVM_ENABLE_LIBCXX=ON 
-DLLVM_LIBDIR_SUFFIX=64 
-DCMAKE_INSTALL_PREFIX=/usr 
-DLLDB_DISABLE_PYTHON=1 
-DTARGET_TRIPLE="x86_64-pc-linux-gnu" 
-DLIBCXX_INSTALL_EXPERIMENTAL_LIBRARY=ON 
-DLLVM_ENABLE_LLD=ON

List of undefined symbols and invocation is next:
