problem building MLT on Karmic [SOLVED]

I'm using the latest FFmpeg SVN sources and the latest git for MLT. Everything rolls along nicely until I hit this snag:

Any advice/suggestions for a fix ?

Re: problem building MLT on Karmic

My guess would be that the wrong version of header files are being used. Maybe you didn't install svn ffmpeg where the mlt make file expects it to be?

EDIT: Or maybe you have old headers still installed somewhere, and those are the ones the mlt make file is finding?

But, be aware that when I tried git mlt not long ago I had problems using it. Rendering to some formats I need would result in a crashed renderer, so I went back to mlt 0.4.6.

Re: problem building MLT on Karmic

Tidris, you were right, I have double installations of some of the libav* stuff, probably due to building/installing every NLE available for Linux. I added --avformat-svn to the MLT compile-time directives, it seems to be compiling fine now. I'll post a report if I run into further problems. Thanks !

Added: The build completed without troubles, so I installed it and opened Kdenlive, LiVES, Kino, OpenShot, and PiTiVi (in succession). Everything appears to be running fine, I'm a happy guy again.

Best,
