Thread: segmentation error

Hi,
I have some problems when compiling a program. I compile the program using:
gcc -o main main.c NN_ev3.a -lm, but i get a segmentation error. I suspect that the eror lies in how i am defining global variables in my main function.

A link to my files are given here:
the .tar.gz file
NN_ev3.tar_2.gz[COLOR="Silver"]
or .zip file
NN_ev3.zip

Can someone help me?
