Could we have a subforum for GnuStep?  Or does anyone even use it?

I know I need to get a macbook so I can take Xcode with me wherever I go, but for now I have a PC laptop.  I was wondering how I could write some of the program examples in GnuStep, is it possible?

All of the program examples in the 1st edition of the book were run with GNUStep.  I didn't continue that into the second edition due to lack of growth of Objective-C outside of the Mac world.  Check this thread:

If there's enough interest, I'll start a new board.  However, I fear you are a member of a very small minority.  Let's get other's input here.

Cheers,

Just for kicks, I followed the instructions in that pdf (I reattached it here so we don't have to jump to other threads) and this is the output I got:

prog1.m: In function `main':
prog1.m:5: error: stray '\147' in program
prog1.m:5: error: `Programming' undeclared (first use in this function)
prog1.m:5: error: (Each undeclared identifier is reported only once
prog1.m:5: error: for each function it appears in.)
prog1.m:5: error: syntax error before "is"
prog1.m:5: error: stray '\' in program
prog1.m:5: error: stray '\148' in program
prog1.m:7:2: warning: no newline at end of file

Yeah, I'm guessing a lot has changed or maybe I'm just doing it wrong.  But I think I'll just wait for a MacBook and then I'll be able to Xcode anywhere.

Did you copy and paste that program from the pdf?  I think your problem has to do with the double quote characters (they have different codes) around the string "Programming is fun.\n".   Try retyping that line in your program and give it another go.

Cheers,

Steve
