hi!
I'm trying to build my own libnetsnmpj.so lib, working with makefiles I get a libnetsnmpj.so file, but when I try to run the examples from java, the JVM crashes, which make me think that maybe I'm compliling in a bad way....
I got some other libnetsnmpj.so files and they throws warnings, my file crashes!!!
here is the stact trace:
