Bug 341005 – media-sound/audacity-1.3.12 fails to compile with ffmpeg-0.6_p25423

• Status: RESOLVED FIXED
• Product: Gentoo Linux

[Description haarp 2010-10-14 16:35:04 UTC]

This seems to be a known problem. The description and solution is listed here:
http://wiki.audacityteam.org/wiki/Known_Issues#Active_issues

"FFmpeg from SVN after June 1st 2010 may cause Audacity not to compile with error "invalid conversion from ‘int (*)(URLContext*, unsigned char*, int)’ to ‘int (*)(URLContext*, const unsigned char*, int)’" in FFmpeg.cpp:257. Workaround: change src/FFmpeg.cpp line 207 from "static int ufile_write(URLContext *h, unsigned char *buf, int size)" to "static int ufile_write(URLContext *h, const unsigned char *buf, int size)" "

Same here


FFmpeg.cpp:257: error: invalid conversion from ‘int (*)(URLContext*, unsigned char*, int)’ to ‘int (*)(URLContext*, const unsigned char*, int)’
make[1]: *** [FFmpeg.o] Error 1

I've added a patch to fix this issue to CVS that allows audacity to be built with any ffmpeg version currently in the tree.
