You can ask a binary which libraries it loads. Use: ldd <name of file> You can learn a bit more here: http://www.yolinux.com/TUTORIALS/LibraryArchives-StaticAndDynamic.html Make sure to check both program binaries and .so files. You wouldn't want to miss something. I don't know if this would be exhaustive but it seems like a good place to start. Although, it might take a while to fully automate it.
