Header file path right?

Should have no problem
Reply:
For example, to compile helloworld.m
gcc-o helloworld helloworld.m -I/GNUstep/System/Library/Headers-fconstant-string-class = NSConstantString -L/GNUstep/System/Library/Libraries-lobjc-lgnustep-base

Content landlord added parameter is not what too few?

-I represents the path of the header file lookup,-L, said the library search path,-l indicates the need to link the library file. However,-fconstant-string-class = NSConstantString for this parameter may be unfamiliar, this parameter is mainly used to specify the constant string class.

Header file path is definitely a problem;
I wrote this demo is similar;
You look carefully, there is certainly not the same as a result of steps.
