Hello, In the AM_PROG_VALAC macro, when the optional parameter specifying the minimum release number is not provided, and if the Vala compiler is not found, then there is a _warning_ message.
On the other hand, when the version number is specified, when the Vala compiler is too old, there is an _error_ message. This error message is problematic, because for a tarball, the Vala compiler is not required: the generated C code is included in the tarball. So if a user wants to compile the software, he shouldn't need the valac program. So the AC_MSG_ERROR should be modified as a AC_MSG_WARN. Best regards, Sébastien
