C ++ error: class has no member named

Question

I have this issue

MemoryBundleStorage.cpp: In member function 'virtual void dtn::storage::MemoryBundleStorage::store(const dtn::data::Bundle&)':
MemoryBundleStorage.cpp:146:67: error: 'const class dtn::data::Bundle' has no member named 'getClass'
MemoryBundleStorage.cpp:150:19: error: 'const class dtn::data::Bundle' has no member named 'getClass'

when compiling this function in Eclipse

void MemoryBundleStorage::store(const dtn::data::Bundle &bundle)
        {
            std::cout << "MemoryBundleStorage store" << std::endl;
            ibrcommon::MutexLock l(_bundleslock);
            std::cout << "Storing bundle(Memory). His class is " << bundle.getClass() << std::endl; //<<Here ERROR
}

Partial Bundle.h file

namespace dtn
{
    namespace security
    {
        class StrictSerializer;
        class MutualSerializer;
    }

    namespace data
    {
        class CustodySignalBlock;
        class StatusReportBlock;

        class Bundle : public PrimaryBlock
        {
            friend class DefaultSerializer;
            friend class DefaultDeserializer;
            friend class dtn::security::StrictSerializer;
            friend class dtn::security::MutualSerializer;

        public:

            int getClass() const;

...
}

And the implementation of the method getClass() is the following (Bundle.cpp)

namespace dtn
{
    namespace data
    {
        Bundle::Bundle()
        {
            // if the timestamp is not set, add a ageblock
            if (_timestamp == 0)
            {
                // add a new ageblock
                push_front<dtn::data::AgeBlock>();
            }
        }

        int Bundle::getClass() const{
                 whatever
                }

}

What am I doing wrong? Maybe the calling is not well done?

Thanks!

You've probably got a forward declaration `class Bundle {}` instead of `class Bundle;`. — Peter Wood, Jun 07 '13 at 09:22
Search your code for `class Bundle` and see whether you declare it more than once. — Peter Wood, Jun 07 '13 at 09:47
as a side note: that kind of use of namespace makes me want to kill myself. C++ is not java. — Balog Pal, Jun 07 '13 at 10:23

Does MemoryBundleStorage.cpp include Bundle.h? Forward declaration is not enough if you want to call member functions.

Yes it does, well it is MemoryBundleStorage.h who has,`#include #include ` – ndarkness Jun 07 '13 at 09:23

In cases like that first thing to do is compile asking for the preprocessor output. Then look in that file for the problem, and trace it back to original source. Common causes include macros or include files picked from other directory.
