Implicit declaration of function when using macros

Question

I'm trying to add custom logging to my objc application. Currently it uses CocoaLumberjack. But I also want the logs to be sent to Crashlytics in case of app crash. So I created a new header file with macroses, which looks basically like this:

#import <CocoaLumberjack/CocoaLumberjack.h>
#import <Crashlytics/Crashlytics.h>

#ifdef DEBUG
static const DDLogLevel ddLogLevel = DDLogLevelVerbose;
#else
static const DDLogLevel ddLogLevel = DDLogLevelWarning;
#endif

#define BKLogVerbose(frmt,...) DDLogVerbose(frmt, ##__VA_ARGS__)
#define BKLogDebug(frmt,...) DDLogVerbose(frmt, ##__VA_ARGS__)
#define BKLogInfo(frmt,...) DDLogInfo(frmt, ##__VA_ARGS__);\
                                CLS_LOG(frmt, ##__VA_ARGS__)
#define BKLogWarn(frmt,...) DDLogWarn(frmt, ##__VA_ARGS__);\
                                CLS_LOG(frmt, ##__VA_ARGS__)
#define BKLogError(frmt,...) DDLogError(frmt, ##__VA_ARGS__);\
                                CLS_LOG(frmt, ##__VA_ARGS__)

Than I'm importing this file where I need extended logging:

#import "BKLogging.h"
...
BKLogError(@"%s, error: %@", __PRETTY_FUNCTION__, error);

But when I try using it I get:

Implicit declaration of function 'DDLogError' is invalid in C99

I understand that compiler cannot find DDLogError function declaration, but I don't know how to fix it (I guess I need to import Crashlytics and CocoaLumberjack to every single file where BKLogging is used, but I'm wondering for better solution).

Use .pch fie for it (precompile header file) and import Crashlytics and CocoaLumberjack — iSashok, Jun 07 '16 at 14:43
