es geht mir prinzipel erstmal nur um den ersten fehler, da ich denke, dass das problem, das dahinter steckt, das grundproblem ist.
danke jetzt schon mal.

jetzt meckert er wegen unresolved external symbol:

in der main.cpp hab ich
#include "StringList.h"

in der StringList.cpp hab ich auch
#include "StringList.h"

is was falsch dran?

also ich wollte mir eine conainerklasse bastel für string.

typedef std::list<std::string> StringList;
// wobei du, deinem Code nach zu urteilen, eher folgendes suchst:
typedef std::vector<std::string> StringVector;
