Another guess would be that you mean the standard type std::map. Did you do an '#include <map>' and a 'using std::map;'?

It's a variable name. The correct typedef syntax is: typedef typename std::map<void , __alloca>::iterator ITEM; - Hide quoted text - Fei Liu wrote: > Neil wrote: >> struct __alloca >> { >> unsigned int nsize; >> int nline; >> char szFile[250]; >> char messages; >> int trace_size ; >> #ifdef OS_WINDOWS >> unsigned long m_size; >> _CRT_ALLOC_HOOK m_poldhook; >> HMODULE m_dbghelp; >> HANDLE m_process; >> HANDLE m_thread; // Pseudo-handle meaning "current >> thread" - required for obtaining stack traces >> DWORD m_tlsindex; // Index for thread-local storage >> of VLD data >> STACKFRAME64 m_frame; >> #endif >> }; >> typedef map<void,__alloca> MEMALLOCMAP; >> typedef MEMALLOCMAP::iterator ITEM; >> I get the error >> error C2143: syntax error : missing ';' before '<' >> error C2143: syntax error : missing ';' before '<' >> error C2653: 'MEMALLOCMAP' : is not a class or namespace name >> Please help me out fast >> TAI >> ~Neil > MEMALLOCMAP is not a class or namespace name, clear enough.
