(1) Your g++ is not interpretting '-dynamic' as an option, it reads '-dy -n
-a -m -i -c'

(2) Your are not getting the static linking right -- you need to be linking
with .a or .o file. Look whether you have libocc.a, if not, build it and
link against it. Make sure to build it with -g for debugging symbols.
