Re: static inline function in precompiled headers

[Ivan Vučica]

Where is your include guard?

#ifndef MYPCH_H_INCLUDED

#define MYPCH_H_INCLUDED

/* current content */

#endif /* MYPCH_H_INCLUDED */

You should use it even if you're used to or expect #import to be used.

Wait, I understand what's happening. It's obeying the "-include mypch.h" flag when it compiles mypch.h. In that case, how do I get similar behaviour to Xcode which automatically includes the headers to the beginning of every .m file?

I am trying to use the precompiled header functionality of GNUstep-make. It seems to work well except that it chokes if I have static inline functions in the header I'm precompiling. I use the XXX_OBJC_PRECOMPILED_HEADERS variable and specify "-include mypch.h" in ADDITIONAL_OBJCFLAGS (the header doesn't seem to get included if i don't since its not referenced in the .m file).

The problem is that when I try to compile, I get errors (below). What am I doing wrong?
