Attachments:	ebuild patch to let mplayer build using gcc's LTO options

Description cmuelle8 2013-03-13 13:28:00 UTC

Though LTO is not officially supported in Gentoo yet, the patch adds just three lines to let the ebuild support it.

Basically, sed checks config.h if the EXTERN_PREFIX definition is properly terminated.  This definition gets improperly set with an embedded newline if lto options of gcc are enabled.

This bug should probably be fixed upstream as well.


Greetings

Reproducible: Always

Thanks for patch.

Yes, thank you for the patch. I was naive to try the patch also with mplayer2. The compilation fail somewhere in the middle with a bunch of such messeges:
