Bug 556450 – media-video/ffmpeg-2.6.3 build fix for sys-libs/uclibc

• Status: RESOLVED UPSTREAM
• Product: Gentoo Linux

[Description René Rhéaume 2015-08-01 13:39:18 UTC]

FFmpeg 2.6.3 fails to build on uclibc as is because the latter lacks fe*except functions.

I made a patch which tests if a double-precision float number can be converted to a 32-bit integer before trying instead of trying the conversion then checking if an exception was raised (that check is using a missign function).

Reproducible: Always

Steps to Reproduce:
1. emeerge -1 ffmpeg
2.
3.
Actual Results:  
emake failed (compile phase)

Expected Results:  
FFmpeg updated on system
