is it possible the gcc linker is not finding the proper lib file ?

all look good, I assume that the linker is add lib in front of the
name of your argument, does it add suffix also ?

look for an option to get the list of libs it found when trying to link.

2 thinks can happen:

the lib name is not the one you think (in windows they have .lib
extension, not .so)
it finds another lib with the same name in another directory.

you have the link cmd, use it directly it will be easier maybe to find
your problem

make sure you understand all the options use for linking, your problem
could be there also.
