[llvm-dev] LLVM code coverage build problem - LLVM_BUILD_INSTRUMENTED_COVERAGE

[Ravi David via llvm-dev]

Hi ,

I am trying to build LLVM instrumented compiler for code coverage .

When I attempted to build the compiler using "-DLLVM_BUILD_INSTRUMENTED_COVERAGE=ON", I end up in the below compiler flag problem.

Please let me know, if you have any info related to this problem or if I have missed anything


cmake -DCMAKE_C_COMPILER=/usr/64bit/bin/gcc \
-DCMAKE_CXX_COMPILER=/usr/64bit /bin/g++ \
-DCMAKE_BUILD_TYPE=Release \
-DLLVM_TARGETS_TO_BUILD="X86" \
-DLLVM_BUILD_INSTRUMENTED_COVERAGE=ON


file /usr/64bit/bin/gcc
/usr//usr/64bit/bin/bin/gcc: ELF 64-bit LSB executable, AMD x86-64, version 1 (SYSV), for GNU/Linux 2.6.9, dynamically linked (uses shared libs), not stripped

/usr/64bit/bin/gcc  -v
gcc version 4.9.4 (GCC)

Problem like below

[  0%] Building CXX object utils/PerfectShuffle/CMakeFiles/llvm-PerfectShuffle.dir/PerfectShuffle.cpp.o
gcc: error: unrecognized command line option ?-fprofile-instr-generate=%4m.profraw?
gcc: error: unrecognized command line option ?-fcoverage-mapping?
make[2]: *** [utils/count/CMakeFiles/count.dir/build.make:63: utils/count/CMakeFiles/count.dir/count.c.o] Error 1
make[1]: *** [CMakeFiles/Makefile2:5589: utils/count/CMakeFiles/count.dir/all] Error 2

Thanks,
Ravi
