I'm currently evaluating a migration path from Apple's WebObjects 4.5
to a SOPE/GDL2 based solution. When porting GDL2 to MacOSX Xcode I
found out that GDL2 often uses constructs like the following in its
headers:
#ifndef NeXT_Foundation_LIBRARY
#include <Foundation/NSArray.h>
#include <Foundation/NSException.h>
#include <Foundation/NSZone.h>
#else
#include <Foundation/Foundation.h>
#endif
This is correct in a GNUstep environment, because some variables
concerning library combos and runtime are always defined there.
Using Xcode on MacOSX this is problematic because these variables are
not defined automatically. Sometimes it's possible to set these in the
respective build environments (Xcode, Makefiles), but this is a tedious
step and sometimes, for larger legacy projects, error prone - as I
currently experienced.
(For completeness' sake, in the example above, without the manual
definition of NeXT_Foundation_LIBRARY the build will fail on MacOSX due
to redefinitions of NSArray and the like.)
My request is to change these statements into:
#ifdef GNUSTEP_BASE_LIBRARY
#include <Foundation/NSArray.h>
#include <Foundation/NSException.h>
#include <Foundation/NSZone.h>
#else
#include <Foundation/Foundation.h>
#endif
It won't change anything in the GNUstep environment, however makes a
bit difference when using this on MacOSX.
Cheers,
Marcus
