Subject: [ruby-core:69423] [Ruby trunk - Bug #11201] pkg_config NoMethodError when finding other -config program
Date: Mon, 01 Jun 2015 09:00:05 +0000 [thread overview]
Message-ID: <redmine.journal-52695.20150601090004.570878e0097d161e@ruby-lang.org> (raw)
In-Reply-To: redmine.issue-11201.20150601064810@ruby-lang.org
Issue #11201 has been updated by Hans Mackowiak.
wx from wxWidgets does have its own wx-config script with does have other flags than pkg-config
(pkg-config in its second version can call (pkg)-config scripts)
thats why:
wx-config --libs-only-l
*** Error: Unrecognised option: '--libs-only-l'
imo it would be nice if it would have checked if that libs-only-l returns something/a string before shellsplit does try to cut it.
i am okay with it that pkg_config("wx") might not be able to get something but imo it would be better if it does return nil instead of NoMethodError
PS: but i think it still would have been nice if it would have been able to return something meaningful.
another sample would be xml2-config from libxml2
PS: i might try to fix that on my own and then i will add a patch

where it maybe not work (other (pkg)-config program)
