Hi, Any ideas why I get this linker errors? Cstring.obj : error LNK2005: "public: __thiscall Cstring::Cstring(class Cstring &)" (??0Cstring@@QAE@AAV0@@Z) already defined in Cgame.obj Ctext.obj : error LNK2005: "public: __thiscall Cstring::Cstring(class Cstring &)" (??0Cstring@@QAE@AAV0@@Z) already defined in Cgame.obj CtextBox.obj : error LNK2005: "public: __thiscall Cstring::Cstring(class Cstring &)" (??0Cstring@@QAE@AAV0@@Z) already defined in Cgame.obj 20jun05.exe : fatal error LNK1169: one or more multiply defined symbols found I have used #ifndef etc to avoid multiple inclusions? or am i missing the point? Thanks Simon

It sounds like you defined functions in your header but outside the class without declaring them inline. That will generate multiple symbol linker errors if you include the header in multiple source files. Either make them inline, by declaring them inside the class definition or by using the inline keyword, or put the function definitions in a separate source file.

For more information see this article.
