Compiling Objective-C Using Cygwin

Thu May 2 18:20:00 GMT 2013

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?
