Hi

I've written a new function for a program.
I have the new_function.c, new_function.h and the new_function.o and I've added those 3 files in the same directory of the others files.
Then in the file.c (that use the new_function.c), I added:
then i try to do:

./configure ........... ok

but the "make" return with:
where "function_added" is defined and implemented in new_function.h and new_function.c.

This is the first time for me, but i read that what i've done should be enough.
Any idea why doesn't work?
Thanks

D.
