Bug 341927 – media-sound/audacity-1.3.12 fails to build with USE=ffmpeg

• Status: RESOLVED FIXED
• Product: Gentoo Linux

[Description Sven E. 2010-10-20 18:41:19 UTC]

media-sound/audacity-1.3.12 fails to build when ffmpeg is enabled.

Reproducible: Always

Steps to Reproduce:
1. Try emergeing audacity with USE +ffmpeg
Actual Results:  
build fails with:

FFmpeg.cpp:257: error: invalid conversion from ‘int (*)(URLContext*, unsigned char*, int)’ to ‘int (*)(URLContext*, const unsigned char*, int)’

Expected Results:  
Clean build

Looks like a Type mismatch and should probably be taken upstream.

Hi,

can you please attach the full build.log and environment files mentioned at the end of the failed emerge process?

Thanks

Upstream already knows about this.

See the Linux section of the active issues at [1] and the bug posting at [2].

Since it is a know issue by upstream folks I assume the build log is not needed anymore?

Audacity ffmpeg patch

The attached patch allows audacity to be compiled with any ffmpeg version.

I'll push it upstream too.
