Hi, Currently, I can build lld/llvm on Fedora 17 but fail to build it on iMac. The commands I use as follows. Anyone can help me? Or is there the lld mail list I can post the question? Linux/Fedora can be built by the following command cmake -DCMAKE_CXX_COMPILER=clang++ -DCMAKE_C_COMPILER=clang -DCMAKE_CXX_FLAGS=-std=c++11 -DCMAKE_BUILD_TYPE=Debug -G "Unix Makefiles" ../src/ make iMac cannot be built by the following command (fail on Xcode compile) cmake -DCMAKE_CXX_COMPILER=clang++ -DCMAKE_C_COMPILER=clang -DCMAKE_CXX_FLAGS=-std=c++0x -DCMAKE_BUILD_TYPE=Debug -G "Xcode" ../src/ Jon...

I regularly use '-DCMAKE_CXX_FLAGS' when configuring CLang/LLVM to distinguish my builds (Alpha/Beta/Final) or to build custom versions, usually by adding additional '-D' flags, but I discovered I had to add the ':STRING' qualifier to it when invoking 'cmake'. With 'gmake' this is equivalent to...

Sorry for the delay, I had to experiment and build everything to be sure. I am actually getting the same problem with GCC v4.9.3 on CentOS, but for both Cygwin and Linux adding '-D_GLIBCXX_USE_C99' to the '-DCMAKE_CXX_FLAGS:STRING=' flag during configuration cured the problem.

...per Command Prompt for VS2019) and I need to know how to switch to a static runtime. I've tried setting LLVM's variable for this, but it didn't work. I still have a dynamic runtime. Along with that, I also need to know how to enable C++ exceptions. One thing I tried was to do "-DCMAKE_CXX_FLAGS="/std:c++17 /MT /EHsc /permissive-"" but this also didn't work. Specifying these on the CXXFLAGS environment variable didn't do anything either. I was using the same session of the Developer Command Prompt, but I made sure to run "refreshenv" to take the new envi...

...and libc++abi on Linux. I looked at the instructions on the libc++ page and for Linux it recommends building with -stdlib=libc++ -lc++abi. Encouraging! Now, how do I get those options to a CMake build of llvm/clang? There's CMAKE_CXX_FLAGS but I'm not sure how to set it. Will a simple -DCMAKE_CXX_FLAGS=-stdlib=libc++ suffice? Will that properly propagate from the command line without overriding all the flags set by individual CMakeLists.txt files? I don't want to, for example, lose optimization flags on a release build. And what about linker flags? What CMake variable controls those? Th...
