Compilation problem using mkoctgfile

Hello everyone,

I just discovered the possibility to use the octave API to make C++ code.  When I try to compile a very simple tutorial example with the following command : mkoctfile helloworld.cpp

I get this warning :

ld: warning, duplicate dylib /usr/local/lib/libstdc++.6.dylib
ld: warning, duplicate dylib /usr/local/lib/libgcc_s.1.dylib


The compiler does generate two files : helloworld.o and helloworld.oct.

But when I try to execute them : helloworld(1,2,3)  it crashes with this error :

error: `example' undefined near line 6 column 1  (even if my file doesn't have 6 lines)

Does anyone have an idea of what my problem could be ?

Thank you very much

Kev
