Re: CPPFLAGS ignored compiling gui

[Fred Kiefer]

Hi Mick,

this sounds a bit strange. You are building GNUstep with clang but point it to 
use the gcc libobjc? This might work but surely it isn’t a recommended setup. 
Why would you want to do that? When using clang you should be using the GNUstep 
libobjc2.

Confused,
Fred
