Re: Portable toolchain

[Kevin Ingwersen]

I have taken my USB drive with GNUstep installed onto to a friends computer.

After setting up PATH, INCLUDE_PATH, and LIBRARY_PATH, it worked…some. I got 
far enough that it is giivng me the error message that there is „No refference 
to ‚NSLog‘“. trying to use @„…“ produces another error about something not 
being loaded. To be very honest, I havent copied the errors, because it was at 
school. Here is the test programm:

#import <Foundation/Foundation.h>
int main() {
        NSString *str = „o.o“;
        NSLog(str);
        return 0;
}

Ultra basic, right? Well, it ocmpiles fine on my mac, but not on GNUstep when 
taken to a different computer.

What environmental variables do the compilers look for? Also during 
installation, a GNUstep folder was created inside the folder I originally 
instaleld my stuff into. Originally, I installed into E:\System - but now I 
also have E:\System\GNUstep - is that normal/ok/safe?

Kind regards, Ingwie

PS: Output on mac:

Ingwie@Ingwies-Air ~/Work/objc $ gcc win.m -framework Foundation

insecure) [-Wformat-security]
