to clear up the cause a little bit:
You make use of the @"somestring" construct in your code. That syntax is
just a shortcut for the creation of a constant string instance - most
likely (at least if you using some OpenStep descendant) of type
NSConstantString. The compiler doesn't know per se what class to
instantiate for that purpose since (unlike in Java) the language ObjC and
the library/framework OpenStep (in this case GNUstep) are a different pair
of shoes. Although they work closely together it is possible to have
another framework with another class hierarchy instead of OpenStep (Swarm
comes to my mind here). To tell the compiler which class to use for
creating constant strings you have to use a compiler flag:
-fconstant-string-class. For example:
-fconstant-string-class=NSConstantString
see also: http://www.dis.com/gnu/gcc/Objective-C-Dialect-Options.html
nevertheless you should use GNUstep-make since it's so much simpler than
compiling by hand.
