On a few of my Fedora 19 machines, I’ve had odd linker problems. Apps that used to work, like k3b’s ripper, Audacity, etc. would fail to run with a linker error, such as:
audacity: error while loading shared libraries: libopenjpeg.so.3: cannot open shared object file: No such file or directory
I checked the packages, and rpmfusion did the proper rebuilds when Fedora changed the version number of libopenjpeg from 3 to 1 (ouch) last year. But rpm told me I had the correct version installed:
$ rpm -q openjpeg-libs openjpeg-libs-1.5.1-5.fc19.x86_64
I tried rebuilding audacity from source (but couldn’t find source reference to libopenjpeg), deleting and rebuilding ld.so.cache, prelink.cache all to no avail. A clue came in when I found the LD_DEBUG=all environment variable and ran audacity under it. It gave nice output like:
29608: file=libopenjpeg.so.3 [0]; needed by /lib64/libavcodec.so.52 [0]

Ah, ha, it’s libavcodec that’s requiring libopenjpeg:
$ rpm -qf /usr/lib64/libavcodec.so.52 ffmpeg-compat-0.6.7-1.fc19.x86_64
So, this is part of the ffmpeg (oldversion) package. yum reinstalling that didn’t help.
But, wait, why is ffmpeg in /lib64? rpm -qf confirms that no package owns it (this may have been due in part to an ugly upgrade to f19). So, is it in /usr/lib64 where one would expect?
$ ls /usr/lib64/libavcodec.so.52* -l lrwxrwxrwx 1 root root 22 Oct 22 17:06 /usr/lib64/libavcodec.so.52 -> libavcodec.so.52.121.0 -rwxr-xr-x 1 root root 6219152 Jul 1 2011 /usr/lib64/libavcodec.so.52.121.0 -rwxr-xr-x 1 root root 4746744 Oct 1 17:33 /usr/lib64/libavcodec.so.52.72.2
Oh, my.
$ rpm -qf /usr/lib64/libavcodec.so.52* ffmpeg-compat-0.6.7-1.fc19.x86_64 file /usr/lib64/libavcodec.so.52.121.0 is not owned by any package ffmpeg-compat-0.6.7-1.fc19.x86_64
OK, then, to slay the beasts, he thinksts:
$ sudo rm /usr/lib64/libavcodec.so.52.121.0 /lib64/libavcodec.so.52
Now, we should be good to go, right?
audacity: relocation error: /lib64/libavformat.so.52: symbol ff_raw_pix_fmt_tags, version LIBAVCODEC_52 not defined in file libavcodec.so.52 with link time reference
Argh. After some googling about, an old ld lib looked like a candidate problem.
$ ls /usr/lib64/ld-* -l -rwxr-xr-x 1 root root 162472 Nov 16 20:34 /usr/lib64/ld-2.17.so lrwxrwxrwx 1 root root 10 Dec 30 00:41 /usr/lib64/ld-linux-x86-64.so.2 -> ld-2.17.so lrwxrwxrwx 1 root root 20 Dec 30 01:09 /usr/lib64/ld-lsb-x86-64.so -> ld-linux-x86-64.so.2 lrwxrwxrwx 1 root root 20 Sep 2 17:37 /usr/lib64/ld-lsb-x86-64.so.3 -> ld-linux-x86-64.so.2
Crikey – so.2 and .so.3 mixed in. Must be multiple versions left after an upgrade.
$ rpm -qf /usr/lib64/ld-* glibc-2.17-20.fc19.x86_64 glibc-2.17-20.fc19.x86_64 file /usr/lib64/ld-lsb-x86-64.so is not owned by any package redhat-lsb-core-4.1-14.fc19.x86_64 $ sudo rm /usr/lib64/ld-lsb-x86-64.so
and then went looking for other libraries that could be in the same situation:
$ rpm -qf /usr/lib64/*so | grep package
And there were a bunch of them. So, in the end, I did:
# rpm -qf /usr/lib64/*.so* | grep package | cut -f 2 -d ' ' | xargs rm
And now all of the apps work again. This will be a new go-to step for a difficult distro update.
