I already pointed you at the wiki page describing how to build from source, and
already commented that your build log looks perfectly fine.
"Nothing to be done for install" happens only in source directories where, hold
your breath, nothing needs to be installed. If you get no "error", then there
is no error, as I did actually mention before.
The problem you are having should be super trivial -- it doesn't seem to be
specific to Osmocom.
I will not try to solve it by email, which is very inefficient for this kind of
problem. I hope you can get someone to help you out with it, maybe taking a
peek over your shoulder. For all I can tell you're already done.
