makefile problem

[ns]

new to makefiles. Heres my problem: I used an xstring (custom) object in a class myClass, which has a functionality test fMyClass. In the makefile I did: fMyClass.x: $(proj)/fMyClass.o myclass.o $(CC) -o fMyClass.x fMyClass.o myclass.o fMyClass.o: $(proj)/fMyClass.cpp $(CC) -c $(incpath) $(proj)/fMyClass.cpp myClass.o: $(proj)/myclass.h $(proj)/myclass.cpp $(cpp)/xstring.h $(cpp)/xstring.cpp $(CC) -c $(incpath) $(proj)/myclass.cpp $(cpp)/xstring.cpp and it gives me errors like: Undefined first referenced symbol in file operator<<(ostream &, XString const &)myclass.o XString::~XString(void) myclass.o XString::XString(char const *) myclass.o I do have xstring.h included in myclass.cpp. What do I need to fix here? The fMyclass doesnt use xstring, but myclass does. thanks, ns

Hi ns, Don't you need also to include an additional xstring.o entry and add it to fMyClass.x? Joaquín M López Muñoz Telefónica, Investigación y Desarrollo

Thats exactly it!! I had been trying different places to put in the xstring.o but it didnt occur to me to add it to the fMyClass.x line as well. Many many thanks! ns
