...m at a loss trying to add Compiler-RT to an LLVM build, even after checking out the instructions at http://compiler-rt.llvm.org, so I'd appreciate your help. I've tried adding the CMake options LLVM_ENABLE_PROJECTS, LLVM_BUILD_EXTERNAL_COMPILER_RT, LLVM_EXTERNAL_COMPILER_RT_SOURCE_DIR, CLANG_DEFAULT_RTLIB. All to no avail. FWIW, I'm building for the targets AArch64, ARM and X86. Feeling like a newbie makes me want to cry... :-} Thank you, -- Evandro Menezes

...tion for LLVM with CMake GUI After it finishes trying to configure, it says that there were errors with the configure step and that program files may be invalid. And I also don't know what executable to point it to for SVN. What should I put for CLANG_DEFAULT_CXX_STDLIB, CLANG_DEFAULT_LINKER, CLANG_DEFAULT_RTLIB, CLANG_DEFAULT_STD_C and CLANG_DEFAULT_STD_CXX? Would it be okay to provide the path to the MSVC include directory for the CLANG_DEFAULT_CXX_STDLIB, or should I provide the path to the include directory in the libcxx folder in the LLVM source tree? For the Linker I think I'll just put llvm_ro...

I probably need GCC for Git bash. And the one I have is MinGW's GCC, which is the one for Windows. I don't know why CMake is trying to find Linux headers. Hopefully someone who knows better what to do will weigh in here. @Jonathan Goodwin<mailto:jondgoodwin at gmail.com> , are you sure you didn't have to tell it where the header files for Windows are? If I need to specify

Hi folks! I'm trying to get rid of any dependency on libgcc*, but without success so far. The following commands were executed on a freshliy installed and updated Ubuntu 16.04 LTS: === snip === sudo apt-get install build-essential libffi-dev cmake # see aptget.txt for packages installed sudo mv /usr/local /usr/local.orig git clone https://github.com/llvm/llvm-project.git cd llvm-project; git

Folks, I'm creating a bootstrap buildbot on AArch64 with LLD and I just realised the "accepted" way to make clang call lld is to "symlink lld -> ld". I understand that's how every Linux system "chooses" the linker, but that makes deployment and validation quite cumbersome on GNU systems. I'd like to suggest a change in behaviour: // Some flag like
