Implicit declaration of function - C99
I had this problem when I did a global replace of NSLog with DLog. I foolishly included the
#define DLog(...) NSLog(...statements, so I ended up with
#define DLog(...) DLog(...which caused the warnings, and a linker error.
Implicit function declarations are those that the compiler sees the first time used as a function call (as opposed to those where a prototype or the function definition is seen first).
Apparently your code used localize(foo) but the macro definition was not visible. Possible reasons: you forgot to #include the file containing the localize macro or the precompilation of headers went south an did not include the localize macro so it was left unexpanded.
Another "foolish" mistake I ran into was the fact that my DLog was defined in the prefix header of the iOS target, so I had to copy it over to the prefix of the OSX target, as well...
