While 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 shared object file: No such file or directory
ffmpeg
ffmpeg: error while loading shared libraries: libavdevice.so.52: cannot open shared object file: No such file or directory
I used the ‘locate’ command to find where the libraries were eg:
locate libcxcore.so.1
This outputted a few locations of where the library was, I decided to use the /usr/local/lib version as both libraries I needed were in there and did the following command to add them to ld.so.conf and reload the dynamic linker:
sh -c 'echo "/usr/local/lib" >> /etc/ld.so.conf && ldconfig'
