Issue with non-system gcc path

CMake mailing list
Hi,

May I know what is wrong with the specifying a non-system gcc path?


$ cmake .. -DCMAKE_C_COMPILER=/storage/users/mnaderan/tools/gcc-6.1.0/bin/gcc -DCMAKE_CXX_COMPILER=/storage/users/mnaderan/tools/gcc-6.1.0/bin/g++                                   -- The C compiler identification is unknown
-- The CXX compiler identification is unknown
-- Check for working C compiler: /storage/users/mnaderan/tools/gcc-6.1.0/bin/gcc
-- Check for working C compiler: /storage/users/mnaderan/tools/gcc-6.1.0/bin/gcc -- broken
CMake Error at /storage/users/mnaderan/tools/cmake-3.15.4/share/cmake-3.15/Modules/CMakeTestCCompiler.cmake:60 (message):
  The C compiler

    "/storage/users/mnaderan/tools/gcc-6.1.0/bin/gcc"

  is not able to compile a simple test program.

  It fails with the following output:

Hi Mahmood,

I think there is a problem with your toolchain. Maybe there is an
environment variable (hot guess: LD_LIBRARY_PATH or something similar)
missing.

Have a look into the following files in your build directory:
  * CMakeFiles/CMakeOutput.log and
  * CMakeFiles/CMakeError.log

Maybe there is some helpful information there?

Best regards,
  Rainer

OK. The OS is centos-6.9 which is pretty old. I think I may hit other errors later.
I will try to find another way. Thank you.
