Hi Colomban - back on your automake bug report from six years ago (sorry!):
Date: Wed, 15 Oct 2014 17:17:00 +0200 From: Colomban Wendling [...] The problem is that parsing of valac flags uses a non-anchored pattern and so any argument happening to be a subset of a parsed argument will match it, e.g. `vapi` will match against `--vapi` or `--internal-vapi`. [... patch ...] --- a/bin/automake.in +++ b/bin/automake.in @@ -5436,8 +5436,8 @@ sub lang_vala_finish_target foreach my $flag ($flags->value_as_list_recursive) { - if (grep (/$lastflag/, ('-H', '-h', '--header', '--internal-header', - '--vapi', '--internal-vapi', '--gir'))) + if (grep (/^$lastflag$/, ('-H', '-h', '--header', '--internal-header', + '--vapi', '--internal-vapi', '--gir'))) { Indeed. I don't see a problem with applying your patch, but before I do, I just wondered if anything else had come up with vala that needs to be fixed? Please advise if you can. I've never used vala myself, so wouldn't know. --thanks, karl.
