Ok so i decided to dive into Objective-C
within the windows system
I downloaded the GNUstep-sys- and the GNU-core-

installed GNU-sys first as instructed on the site
the core

But i had installed Strawberry some time back for running some network scripts with perl

now the gcc that's being used is from Strawberry not the GNUstep that I've installed

and when i trey to compile Objectiv-C code the bellow error strike
please if anyone out there has a solution
