I have some portability issues when I mix ARC with some occasional manual
retains (especially when hand writing encoders and decoders).
The offending function is CFRetain and CFRelease, which is, as documented by
Apple, recommended as replacements of (forbidden by ARC) -[NSObject retain] and
-[NSObject release] methods.
However due to the structural difference of GNUstep libraries, the
aforementioned two functions are missing.
Currently I resort to conditionally compiled inline function wrappers (same
name and signature, different implementation) to handle this issue, as done in
the following code snippet (extracted from ohttpd2 project, 2-clause BSDL
licensed, hosted at https://github.com/xcvista/ohttpd2):
#ifdef GNUSTEP
#import <objc/objc_arc.h>
static inline id CGIRetain(id obj)
{
return objc_retain(obj);
}
static inline void CGIRelease(id obj)
{
objc_release(obj);
}
#else // GNUSTEP
#import <CoreFoundation/CoreFoundation.h>
static inline id CGIRetain(id obj)
{
return (__bridge id)CFRetain((__bridge CFTypeRef)obj);
}
static inline void CGIRelease(id obj)
{
CFRelease((__bridge CFTypeRef)obj);
}
#endif // GNUSTEP
If you can move the aforementioned methods from CoreBase to Base, this
portability issue can be addressed.
