Thanks for your reply.

I was using gcc directly to compile my program:
1) compile main.m to main.o ： 
gcc -fconstant-string-class=NSConstantString -c main.m -I 
/GNUstep/System/Library/Headers 
2) Fraction.m to Fraction.o ： 
gcc -c Fraction.m -I /GNUstep/System/Library/Headers 
3) compile *.o to main (actually is main.exe) 
gcc -o main main.o Fraction.o -L /GNUstep/System/Library/Libraries/ -lobjc 
-lgnustep-base

But the first command terminated me with those error. But I can see all *.h 
file under /GNUstep/System/Library/Headers directory.
