Compiling Objective-C Using Cygwin

[Eric Kessler]

I am trying to learn Objective-C using Cygwin.

First I wrote a hello world program in C and compiled it thus:

gcc -o inventry inventry.c

and it worked perfectly.

Then I renamed the source file inventory.m, and since every C program 
should be a valid Objective-C program, compiled it thus:

gcc -o inventry inventry.m -lobjc

and got the following error:

gcc: error trying to exec 'cc1obj': execvp: No such file or directory

I did a web search of that error message, and found that I needed to 
install gobjc.  I could not find gobjc on the installer package from the 
mirror site from which I had originally installed cygwin, so I got it from 
a site called "ubuntu" and installed it.  Now I get the following error:

gcc: error trying to exec '/usr/lib/gcc/i686-pc-cygwin/4.5.3/cc1obj': 
execv: Exec format error

I did a web search of that error, and found something that said that 
cygwin was not installed properly and needs to be reinstalled.  I assume 
that means that the version of gobjc that I installed from "ubuntu" was 
not compatible with my cygwin installation.

So how do I get gobjc from the standard installer package?  I don't see it 
listed in the list of packages to install?
