[Slackbuilds-users] OpenJPEG needs a linking patch

[Doogster]

Future versions of the openjpeg SlackBuild should apply the following patch:

http://sources.gentoo.org/cgi-bin/viewvc.cgi/gentoo-x86/media-libs/openjpeg/files/openjpeg-1.4-linking.patch

To not use the patch cause openjpeg to be built but not linked against
-lm. The result is that if you try to build ffmpeg 0.8.1 with support
for both openjpeg and almost any other codec (including specifically
Dirac and OpenCore), the configure fails. Ffmpeg's configure log will
the show that symbols like "pow" were not found in the openjpeg
libraries.
