[LLVMdev] CMake does not propagate flags to build
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 '--with-extra-options="whatever flags": -DCMAKE_CXX_FLAGS:STRING="whatever flags" This works regardless of whether it is a Debug or Release build.

Hey, Thanks for ideas. I tried them on, but none of them succeeded. If I remove this line: https://github.com/llvm-mirror/compiler-rt/blob/c9d8d35a5c2bdd6a0dd41f1b6cf3afb822df6a6e/CMakeLists.txt#L207 Everything is correctly built with -fno-omit-frame-pointer. Any suggestion why it would be the case? Thanks, Adrian On Mon, Jul 20, 2015, at 01:39 PM, Martin J.

Wait… This is just for compiler-rt? +Samsonov I don’t know if we explicitly don’t support -fno-omit-frame-pointer for compiler-rt, but in general compiler-rt is generally built differently from LLVM & Clang for a reason. Why do you need -fno-omit-frame-pointer for compiler-rt? -Chris> On Jul 20, 2015, at 2:23 PM, adek at adek.io wrote: > > Hey, > > Thanks for ideas.

This is just for compiler-rt. The reason for having -fno-omit-frame-pointer is that tools like https://perf.wiki.kernel.org/index.php/Main_Page would work on ASAN binaries.
