--------------------------------------

             Summary: latest asterisk unconditionally launch gcc --version, even if the compiler is different
                 Key: ASTERISK-28374
                 URL: https://issues.asterisk.org/jira/browse/ASTERISK-28374
             Project: Asterisk
          Issue Type: Bug
      Security Level: None
          Components: Core/BuildSystem
    Affects Versions: 16.3.0, 13.26.0
         Environment: Any where main compiler is named differently than gcc, but there is also gcc 8.x around.

Encountered in the FreeBSD port.
            Reporter: Guido Falsi
            Severity: Minor


In latest asterisk a check for GCC version has been added. It is performed by unconditionally running "gcc --version".

If the main compiler being used is another one (F.E. cc) this check will test the wrong compiler and add compiler flags which may be incorrect.

On FreeBSD the main compiler is clang, named cc. When gcc 8 is installed on the system, this check will return true, and add a compiler flag which is refused by clang, causing the build to fail.

I'm going to propose a review on gerrit patching the Makefile to perform the check using the $(CC) variable, containing the actual compiler being used for the build.
