            Bug ID: 36818
           Summary: Checking provided compilation parameters
           Product: tools
           Version: 5.0
          Hardware: PC
                OS: Linux
            Status: NEW
          Severity: normal
          Priority: P
         Component: llvm-config
          Assignee: unassignedbugs at nondot.org
          Reporter: Markus.Elfring at web.de
                CC: llvm-bugs at lists.llvm.org

The following software packages were installed also on my openSUSE Tumbleweed
system.
* GCC 7-2.9
* llvm5-devel 5.0.1-4.3


I have noticed the software situation that the command “llvm-config --cflags”
can provide a compilation parameter which will trigger the message “cc: error:
unrecognized command line option ‘-Wstring-conversion’; did you mean
‘-Wint-conversion’?”.

Example:
https://build.opensuse.org/package/show/openSUSE%3AFactory/smatch

If I try another software build try out by a command like “make CC=clang …”, it
can succeed.


How should this configuration tool be improved?
