Description Shane Peelar 2017-09-18 21:07:02 UTC

In https://bugs.gentoo.org/566282 , the ebuilds for media-video/ffmpeg were amended to support LTO.  Unfortunately, they do not respect the -fno-lto flag, particularly if your CFLAGS/CXXFLAGS contain "-flto -fno-lto" -- it will build with "--enable-lto" regardless.

A comment on that bug report suggested a fix: https://bugs.gentoo.org/566282#c6

I have tested this fix on my own overlay and it appears to work as intended.  I can submit patches to fix the ebuilds using this if desired.

Thank you for your time,
Shane Peelar
