error: core dumped

[ViNiCiUs <vlpg terra com br>]

I'm a newbie and I'm learning how to work with images...
I compile a file test using "gcc  file.c -o file `pkg-config --cflags 
--libs gtk+-2.0`
When I try to execute the file, I recept the error "core dumped".
So, someone know what is wrong in this file ?

I want to get image.jpg and put in a vector, then after I can to 
manipulate the pixels

                        Thanks for the Help - ViNiCiUs
