Trouble compiling command-line application

[zauhar]

Hi folks,

I have been working with Cocoa for a while, but this is my first 
experience with GNUstep.

I am starting out by trying to port a fairly small command-line 
application from OS X to Redhat Linux 3.2.2-5 (gcc 3.2.2)

I installed the latest distributions of gnustep base 
(gnustep-base-1.9.0.tar), backend (gnustep-back-0.9.1.tar) and make 
(gnustep-make-1.9.0.tar), and I am able to build some small test apps I 
found in the docs. However, when I try to build my own application, I 
get this when compiling main.m :

<...various warnings...>
main.m:285: warning: assignment discards qualifiers from pointer target 
type
main.m:311: warning: passing arg 1 of `initWithFlatFile:andMolFile:' 
discards qualifiers from pointer target type
main.m:311: warning: passing arg 2 of `initWithFlatFile:andMolFile:' 
discards qualifiers from pointer target type
main.m:363: warning: assignment discards qualifiers from pointer target 
type
/usr/include/bits/socket.h: At top level:
/usr/include/bits/socket.h:279: redefinition of `v'
/usr/include/bits/socket.h:279: `v' previously declared here
make[1]: *** [shared_obj/main.o] Error 1
make: *** [rayTrace.all.app.variables] Error 2

This application compiles and works fine under OS X. Thinking there 
might be something funky with #import under linux, I wrapped my header 
files in #ifndef's and switched to using #include. Same behavior.

I also started playing with the includes - in particular, I went 
through and changed all #include <Foundation/Foundation.h> to 
<Foundation/NSObject.h> which is adequate for some of my classes. This 
results in the same sort of error, but now the final messages are

main.m:363: warning: `NSString' does not respond to `cString'
/usr/lib/gcc-lib/i386-redhat-linux/3.2.2/include/objc/sarray.h: At top 
level:
/usr/lib/gcc-lib/i386-redhat-linux/3.2.2/include/objc/sarray.h:235: 
redefinition of `v'
/usr/lib/gcc-lib/i386-redhat-linux/3.2.2/include/objc/sarray.h:235: `v' 
previously declared here
make[1]: *** [shared_obj/main.o] Error 1
make: *** [rayTrace.all.app.variables] Error 2

Note same crap about "redefinition of `v'", but now in a different 
file. Something really spurious is going on.

If anyone has advice I would be grateful!

Discussion after watching Disney's "Lilo & Stitch":

DAD: "But why did the space aliens speak English, as opposed to French, 
or Swahili? And why did the one alien speak English with an Eastern 
European accent? I don't get it."
