Hi Adrian I’m not sure if the CMAKE_CXX_FLAGS is used in LLVM. We have our own flags for different configurations. I don’t remember if our ones inherit from CMAKE_CXX_FLAGS or override it completely. Anyway, they are: - CMAKE_CXX_FLAGS_DEBUG - CMAKE_CXX_FLAGS_MINSIZEREL - CMAKE_CXX_FLAGS_RELEASE - CMAKE_CXX_FLAGS_RELWITHDEBINFO The one of those you get depends on what you set CMAKE_BUILD_TYPE to. Options are ‘Debug, Release, RelWithDebInfo, MinSizeRel’ Cheers, Pete> On Jul 17, 2015, at 8:41 PM, adek at adek.io wrote: > > '-DCMAKE_CXX_FLAGS=-fno-omit-frame-pointer -Wno-maybe-uninitialized > -fPIC -fPIE' > -- The C compiler identification is GNU 4.8.1 > -- The CXX compiler identification is GNU 4.8.1 > -- Check for working C compiler: > /home/engshare/third-party2/gcc/4.8.1/centos6-native/cc6c9dc/bin/gcc > -- Check for working C compiler: > /home/engshare/third-party2/gcc/4.8.1/centos6-native/cc6c9dc/bin/gcc -- > works > -- Detecting C compiler ABI info > -- Detecting C compiler ABI info - done > -- Detecting C compile features > -- Detecting C compile features - done > -- Check for working CXX compiler: > /home/engshare/third-party2/gcc/4.8.1/centos6-native/cc6c9dc/bin/g++ > -- Check for working CXX compiler: > /home/engshare/third-party2/gcc/4.8.1/centos6-native/cc6c9dc/bin/g++ -- > works > -- Detecting CXX compiler ABI info > -- Detecting CXX compiler ABI info - done > -- Detecting CXX compile features > -- Detecting CXX compile features - done > -- Found PythonInterp: > /home/engshare/third-party2/python/2.7.5/centos6-native/da39a3e/bin/python2.7 > (found version "2.7.5") > -- Looking for unwind.h > -- Looking for unwind.h - found > -- Performing Test COMPILER_RT_HAS_FPIC_FLAG > -- Performing Test COMPILER_RT_HAS_FPIC_FLAG - Success > -- Performing Test COMPILER_RT_HAS_FPIE_FLAG > -- Performing Test COMPILER_RT_HAS_FPIE_FLAG - Success > -- Performing Test COMPILER_RT_HAS_FNO_BUILTIN_FLAG > -- Performing Test COMPILER_RT_HAS_FNO_BUILTIN_FLAG - Success > -- Performing Test COMPILER_RT_HAS_FNO_EXCEPTIONS_FLAG > -- Performing Test COMPILER_RT_HAS_FNO_EXCEPTIONS_FLAG - Success > -- Performing Test COMPILER_RT_HAS_FOMIT_FRAME_POINTER_FLAG > -- Performing Test COMPILER_RT_HAS_FOMIT_FRAME_POINTER_FLAG - Success > > Is it still related to this: > http://lists.cs.uiuc.edu/pipermail/llvmdev/2014-March/071394.html > > > Adrian Zgorzałek > > _______________________________________________ > LLVM Developers mailing list > LLVMdev at cs.uiuc.edu http://llvm.cs.uiuc.edu > http://lists.cs.uiuc.edu/mailman/listinfo/llvmdev
Hey Pete, I also tried CMAKE_CXX_FLAGS_RELEASE with the same effect. On Mon, Jul 20, 2015, at 09:34 AM, Pete Cooper wrote:> Hi Adrian > > I’m not sure if the CMAKE_CXX_FLAGS is used in LLVM.
