mgWalk parst hirarchy in einem file u führt bei jedem punkt in hirarchy &c_fltBase::Check aus....

datentypen aus api:
mgrec * (ist struct)
mgbool (bool mit MG_TRUE/MG_FALSE)

//c_fltBase.h

class c_fltBase
{
	 char *output;
	 mgrec *lodnode;

	public:
		static char *charlodname;
		vector<string> alllods;

		//c_fltBase();

		//~c_fltBase();

		static mgbool Check (mgrec *startingnode, mgrec *parent, mgrec *currentnode, void *output)
		{
			mgcode nodetype = mgGetCode(currentnode);
			if (nodetype == fltLod)
			{
				charlodname;
				string strlodname = static_cast<string> (charlodname);
			}
			return (MG_TRUE);
		}

		void FindAllLODs (mgrec *&base,  std::vector<std::string *> &lodresults)
		{
			mgWalk (base,  :mad: &c_fltBase::Check  :mad: , MG_NULL, output, (MWALK_NEXT, MWALK_NORDONLY));			
		}

};

//main.cpp

void main ()
{
	mgrec * db;

	c_fltBase test;

	vector<string *> stringTest;

	test.FindAllLODs(db, stringTest);   //wenn ich die zeile ausklammere dann kein error
}

vs 2005 compiler:

1>Compiling...
1>main.cpp
1>Linking...
1>main.obj : error LNK2001: unresolved external symbol "public: static char * c_fltBase::charlodname" (?charlodname@c_fltBase@@2PADA)

wär super wenn mir jem. helfen könnte bin schon ziemlich am verzweifel

danke im vorhinein

1>Compiling...
1>main.cpp

im .cpp meint der compiler:

funktioniert
vielen dank

könnt ma vl noch jem erklähren wiso ich im cpp file redeklarieren muss?

NIcht deklarieren tust du im cpp file, sondern definieren!
