GNUstep and DirectFB

[Alan West]

Hi,

I'm new to gnustep and this list so....
About me: UK C/C++ programmer for 8 years commercially, originally ANSI 
C, then MFC,STL, and more recently ATL,WTL, COM, OLEDB.... I've been in 
search of something which enables me to develop software for different 
platforms easily for the past year or two, I've evaluated all sorts of 
libraries and technologies from cross platform windowing libs, to 
Mono/C#/.NET etc, Mozilla's cross platform support, and out of all this 
nothing has impressed me as much as the openstep/gnustep/Objective-C 
stuff, the Renaisance stuff looks awesome too, not sure I like the menu 
support though - must be a way to get the menu to work for all platforms 
instead of an extra Apple specific one.

I had a play with writing display server support using DirectFB (seeing 
as it includes window management), but got stuck at the first hurdle of 
including the directfb header file... its as though the Objective-C 
compiler doesn't expand the macros fully (macros defining DirectFB 
interface structs).. and fails to parse an enum with its value shift by 
another enum value... so....
Does anyone already know if the directfb.h file is a true ANSI C header 
file?
Or do I have to set an option with the compiler when including this kind 
of header file?
Has anyone already done this?
Or any other ideas (using gcc3.2.1 on Gentoo Linux)?


Thanks
Alan
