4 Feb 2010symbol lookup error: /usr/local/lib/libhighgui.so.4: undefined symbol: av_free_packet
To fix it simply make sure /usr/local/lib is in your library path by using the following command:
export LD_LIBRARY_PATH=/usr/local/lib:$LD_LIBRARY_PATH

2 Feb 2010While installing opencv on an older version of debian for work I kept getting an error while loading shared libraries which turned out to be a pretty easy fix, just finding the libraries and adding them to the dynamic linker.
The libraries I was having trouble with below:
./blobtrack: error while loading shared libraries: libcxcore.so.1: cannot open [...]
Error: Dependency is not satisfiable: libstdc++5
This is a simple fix, just grab the libstdc++5 package for your architecture from here:
http://packages.debian.org/stable/base/libstdc++5
