Jan, You'd need to checkout the Cinelerra source code from subversion: http://cvs.cinelerra.org/svnusage.php#anon
make the edit as specified in Marcin's email: https://init.linpro.no/pipermail/skolelinux.no/cinelerra/2006-November/008696.html to edit line 357 in libmpeg3/video/seek.c in the Cinelerra source directory. Then recompile. of course, to compile from source, you need all the programs Cinelerra is dependent upon. For my Fedora system, I've listed them here: http://crazedmuleproductions.blogspot.com/2006/08/fc4-dependencies-for-cinelerra-cvs.html scott On Sat, 2006-11-18 at 21:07 +0100, Jan Luo wrote: > hi, > > same thing here. how and where could i apply the fix - in gentoo? > am not a coder but know how to use an editor;-). > > cheers > > jan > > Scott C.
