Unhappy warning : /usr/lib64/libavcodec.so: undefined symbol:


Running Suse 9.3Pro 64bit version.

I had issues trying to compile ffmpeg and transcode. Similar I believe in basic error description until I removed the --enable-shared option from ffmpeg and transcode when compiling. No errors then and it installed. Gv4l when trying to record provides the following below. No luck with mencoder either and it compiled fine.

Since it's related to linking between 32bit and 64bit libraries, I posted this under this topic as I don't believe it's related to any of the apps. They are only calling shared libraries from the system which is where the problem seems to be in my opinion.

Any feedback would be greatly appreciated.

Thanks

Tony

Hmm - you say you got it to compile by -REMOVING- --enable-shared in the FFMPEG configure line?

On my FC3 setup, NOT having --enable-shared made sure that Transcode (which obviously depends on FFMPEG) would NOT compile. To get everything working I had to

FFmpeg configure line:

./configure --enable-mp3lame --enable-vorbis --enable-pthreads --enable-shared
--cpu=p4

./configure --enable-mmx --enable-sse --enable-sse2 --enable-freetype2
--enable-avifile --enable-lame --enable-ogg --enable-vorbis
--enable-libdvdread --enable-lzo --enable-libmpeg3 --enable-libxml2
--enable-mjpegtools --enable-sdl --enable-gtk --enable-libfame
--enable-libjpeg --with-x

It is exceedingly strange that it works (actually not works, right?) in reverse with you. Did I understand correctly in my summation? The only possible solution might be to get the latest FFMpeg you can lay your hands on, and try to compile it with --enable-shared before trying to compile transcode...

You are correct. If I used --enable-shared, I got a libavcodec error, without it went fine. I dropped FC3 a few months back because of RH's and the Fedora Project's insistence at literally ripping out the guts for multimedia capability. Same with Mandrake/Mandriva. Suse put it back in. I also had other issues with Fedora in that the 64bit flavor just stunk. Incomplete.........

I have the latest ffmpeg and next to latest transcode since the latest is an incomplete download or produces an empty archive upon download retrieval. States file size is 2.3 mb or something like that and it's actually 2.2mb.
