 * ERROR: media-video/mkvtoolnix-6.9.1::gentoo failed (configure phase):
 *   econf failed
 * Call stack:

From what i understand, qt is an option, but when qt is enabled, then only qt5 can be used. On gentoo, qt5 is provided by dev-qt/qtcore:5, which is indeed installed on my system. moc is then found in


And the configure seems not aware of this, so i wonder how it was supposed to work ..???

Reproducible: Always

In an autoconf-based build system, the location of moc should be determined via pkg-config.
Comment 2 Tim Harder gentoo-dev 2014-05-19 19:45:58 UTC
The qt5 use flag is masked for mkvtoolnix because qt5 isn't in the tree yet. If you're unmasking the use flag you're currently on your own.
