I still don't understand why after installing it on the system the libraries aren't linked up properly.
$ guestfish --version guestfish: error while loading shared libraries: libguestfs.so.0: cannot open shared object file: No such file or directory
Is /usr/local/lib in the dynamic linker path? You might need to add it to '/etc/ld.so.conf'.
My linux skills are "questionable' but I'd thought something like that would have already been properly configured when gcc gets pulled down and installed with a package manager. But I'm learning... My ld.so.conf file references all '*.conf' in /etc/ld.so.conf.d/. And /usr/local/lib is present in one of them. In order to get libguestfs-test-tool to work I made this link: sudo ln -s /usr/local/lib/libguestfs.so /lib/x86_64-linux-gnu/libguestfs.so.0 If there is a more correct solution please let me know.
