OK, so I've got gnustep-base and gnustep-make installed. I'm trying to
follow the code as given on the "Objective-C for Beginners" website which
is
refrenced from the gnustep.org website.
I am getting the following error when I try to compile the simple
fractions example:
prompt% make
Making all for objc_program fraction_driver...
Compiling file fraction_driver.m ...
Compiling file fraction.m ...

make: *** [fraction_driver.all.objc-program.variables] Error 2
What am I doing wrong ? I'm just trying to compile a simple
Objective-C program, using the GNUstep make system.
You are building a standalone program which doesn't use the GNUstep base
library ... as such, you can't have it usse anything in the base library
(such as NSObject).
This is probably not what you want.
I guess you want to build a command-line tool using the base library ... for
that your makefile needs to use TOOL_NAME rather than OBJC_PROGRAM_NAME, and
include tool.make rather than objc.make
