Finding and removing libraries that are the same but of different versions

[jjrose]

Is there a way to search for libraries that you may have installed two versions of? I am getting an undefined symbol error in a program that I wrote and I believe it may have to do with installing a library twice, with different versions. But I don't know which one. Is there a way to search for these so that I can remove the duplicates?

Thanks in advance,
Jason

If you installed the library using Ubuntu's package manager, that probably isn't your problem. Could you tell us exactly how you installed the library twice?

I thought it was using the package manager, but I found out it may be that I somehow installed two versions of ROOT, the program I am working with, so I believe that is the problem. I should figure it out shortly...
