Error when adding pointer to class in different namespace?

Question

For some reason I keep getting "../Svc/../Drv/Timer.h:18:12: error: 'svc' has not been declared" when I compile. Can't figure out why...

Timer.h File

#include "../Svc/TimerManager.h"

namespace drv {

class Timer {
public:
    void Init(svc::TimerManager *aTimerMan);

private:
    svc::TimerManager *timerMan;

    };

} /* namespace drv */

TimerManager.h

#include <stdint.h>
#include "../Drv/Timer.h"

namespace svc {

/*
 *
 */
class TimerManager {
public:
    uint8_t msec10;
    uint8_t sec;
    uint8_t min;
    uint8_t hour;

    void Init();
    void IncrementTime();

private:
    drv::Timer timer;

};

} /* namespace svc */

What happens if you write ``::svc::TimerManager`` ? Note the ``::`` in front. — BitTickler, Mar 08 '15 at 22:29
Compiler : error: 'svc' in namespace '::' does not name a type. When I add the :: in front — user1785853, Mar 08 '15 at 22:35
Is that an embedded compiler, such as Diab by any chance? I know some have problems with namespaces still. — BitTickler, Mar 08 '15 at 22:35
@user2225104: all compilers have problems with circular dependencies. — Mike Seymour, Mar 08 '15 at 22:39
Just noticed the circular stuff lol. Yeah - looks like the design needs some cleanup. — BitTickler, Mar 08 '15 at 22:40

Both headers try to include each other, which is impossible.

Luckily, Timer.h doesn't do anything with TimerManager to require a complete definition; so don't include that header, just declare the class:

namespace svc {class TimerManager;}
