Compilation failure in configure with syntax error near unexpected token -Wall,WFLAGS and AX_CHECK_COMPILE_FLAG

If you are trying to build program and in the configure stage you got something like this:

./configure: line 6849: syntax error near unexpected token `-Wall,WFLAGS="$WFLAGS -Wall"'
./configure: line 6849: `AX_CHECK_COMPILE_FLAG(-Wall,WFLAGS="$WFLAGS -Wall")'

You are missing


Check your system for the package including this software (a collection of freely re-usable Autoconf macros):

In our case we were experiencing a missing dependency for “app-admin/metalog” in Gentoo Linux system. Probably there is a bug, because autoconf-archive is not in the dependency graph of “app-admin/metalog” (app-admin/metalog-20181125), but it should be included.
Such kind of error could occur in all Linux systems. Here is what to install in

  • CentOS 7
    yum install autoconf-archive
  • Ubuntu 16/17/18+
  • apt install autoconf-archive
  • Gentoo Linux
  • emerge -va autoconf-archive
