[Description Frank Krömmelbein 2014-08-08 09:05:20 UTC]

I rebuild my system with gcc-4.8.3 and got this problem with version 1.2.6-r1 and 1.2.7.

[Comment 3 Magnus Granberg 2014-08-08 12:37:52 UTC]

Try to build it with the pic use flag on

[Comment 4 Frank Krömmelbein 2014-08-08 13:40:42 UTC]

With PIC useflag enabled, ffmpeg-1.2.6-r1 compiles.
Thank you very much!

> media-video/ffmpeg:pic - Force shared libraries to be built as PIC (this is slower)

Can it be estimated how much speed this costs, or increases this just the compile time of ffmpeg?

on amd64 nothing as this is mandatory
on x86, esp. with ffmpeg, a lot since this disables _all_ asm optimizations...


hardened should use.force pic for amd64 here since the failure comes from the x86 multilib build

[Comment 6 Alexis Ballier 2015-02-15 09:38:09 UTC]

@jer: please read; i provided a solution which is to add something to hardened profiles; nothing to do for media-video herd here...
