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.
