That error really concerns libopt.a. You're trying to link static
library (libopt.a) into dynamically-loaded (yourPLugin.so) library,
which will not work (IIRC) unless (a) the .a is recompiled with -fPIC,
or (b) you compile shared library libopt.so (that will be compiled with
-fPIC, too), which will be loaded by your plugin at runtime.
