Doxygen warning: no uniquely matching class member found for

I'm using Doxygen for a C++ project. When I'm building the html doc, I get the following error:

C:/Amir/Programming/Eclipse C++/CacheOptimization/src/CacheLruNaiveAlgorithm.cpp:19:

warning: no uniquely matching class member found for

void CacheOpt::CacheLruNaiveAlgorithm::init(TierList &tierList, TierMap *tierMap)

What could be the source for this warning? What usually causes it?

Edit:

Edit:

Here's a sample method definition/declaration that doxygen is complaining about (I removed some stuff, like the parameter types, because it is IP protected. There are no macros used anywhere):

Algorithm.h

namespace CacheOpt {
    class Algorithm {
        protected:
            /*..*/
        public:
            virtual void init(/*..*/);
            virtual std::string getName() = 0;
    };
} //CacheOpt

Algorithm.cpp

#include "Algorithm.h"

void
CacheOpt::Algorithm::init(/*..*/) {
    /*..*/
}

I get this error here:

C:/Amir/Programming/Eclipse C++/CacheOptimization/src/Algorithm.cpp:11: warning: no uniquely matching class member found for void CacheOpt::Algorithm::init(/*..*/)

and it doesn't even identify Algorithm as a class! What can I do?

Possible causes:

• If you are trying to remotely associate comments with code by using tags like \function and \class, stop. Putting the documentation comments immediately before the code in question will automatically associate it, make it more likely that the code maintainer will update the comment when modifying the code, and completely remove the burden of updating function signatures in the comment.

• A class member with an out-of-class implementation has a source code mismatch between the signatures of declaration and definition. According to the C++ standard, things like top-level const do not change the signature, but doxygen works on source code and tries to match things using different rules from the compiler. Typedefs and macros may also play a role, where the compiler sees a definition corresponding to the declaration while doxygen sees two separate functions. It might be possible to resolve this by telling doxygen to expand certain macros, or it might be necessary to tweak the declaration to exactly match the definition.

• Using the scope operator with namespaces or multiple times in the same name. Some of doxygen's code assumes that the scope operator is used with types rather than namespaces. Using a namespace block instead is a reasonable workaround. I've also seen issues where the scope resolution operator is used more than once, doxygen may keep too many scopes when it moves on to processing the next code snippet. Keep your code simpler, and doxygen will like it better.

For your code example, this may work better:

#include "Algorithm.h"

namespace CacheOpt
{
    void Algorithm::init(/*..*/)
    {
        /*..*/
    }
}

If this is a workaround, feel free to use it, but also file a bug report on the doxygen bug tracker.
