Gpac fails to link on Leo

[Randrianasulu]

av_stream_add_side_data not found

probably wrong (too new?) version of ffmpeg?

I think you run a dirty build (and perhaps it picks headers from one ffmpeg and libs from another).

The build worked fine from my port, and there were no updates since then.

sudo port clean gpac
sudo port deactivate ffmpeg
sudo port -v install gpac

will probably work.

Maybe this will ensure against picking inconsistent ffmpeg versions: macports/macports-ports@30e8d6a
But I will try adding that on the next update.

If you still get the linking error with clean build, let me know.

[Randrianasulu]

Yes, deactivating ffmpeg first helped. Build finished. But may be user msg telling user to do this step will be nice.
