Re: .so Library Question

Thanks Criag. I followed your advise and also did the following which
seemed to work (say I have libmylib.so as an external shared library):

g++ -share example3.o example3_wrap.o -L. -lmylib -o _mynewlib.so 

(so now I have one shared lib)
and in python I did

>>> import mynewlib

It works.

Thanks again
