Is there any chance to get gcc check my passed parameters the "Objective-C way" with "%@" included but still having the format string passed as plain old C-string? It there any other types than __NSString__ I could try? BTW, is there an official list what types are accepted by __attribute__((format(...))) ?
This NSString does not seem to be recognized by gcc at all. I see that llvm handles it. (http://llvm.org/viewvc/llvm-project/cfe/trunk/lib/Sema/SemaDeclAttr.cpp?revision=97103&view=markup) Are you sure you use gcc? Compiling: #import <Foundation/Foundation.h> void mlog(NSString *format, ...) __attribute__((format(__NSString__, 1, 2))); leads to: toto.m:3: warning: ‘__NSString__’ is an unrecognized format function type with gcc 4.4 and GNUstep stuff. Apart from that, the gcc documentation tells what types you can use in __attribute__ format stuff. (Here when I do "info gcc", in the C Extensions -> Function Attributes it is described and allowed stuff is: `printf', `scanf', `strftime', `gnu_printf', `gnu_scanf', `gnu_strftime' or `strfmon'. (You can also use `__printf__', `__scanf__', `__strftime__' or `__strfmon__'.) On MinGW targets, `ms_printf', `ms_scanf', and `ms_strftime' are also present. ) My .1 euros...
