>Description:
it compiled the other code just fine
it is running this from a Makefile

it regonize's MODULE* objects but not the wrap varible or the
functions defined inside mikmod.h

it seems to me that when it checks for object varibles and methods that
it forgets to check for anyother varibles and methods out side the object.


>How-To-Repeat:
make the source.
compile like this
c++ -o mplayer.o -c MPlayer.cpp -I/usr/local/include

"-I/usr/local/include" is where the mikmod.h file resides.      
>Fix:
i can only guess to check if its looking for global varibles along with
the local varibles of the object and there methods
