Ok I finally got my headers to work correctly. At first I was getting linker errors, then all I did was cut the .cpp and .h files and put them in another folder, and BINGO it worked. So I proceeded in attempting to code the rest of the project, but once I found that the classes I made needed more accesors and other things, I decided to delete the work I did on one of the .cpp files and restart from scratch. Once I did that I recompiled everything and started to build everything again, when the linker errors came up. I don't get what is happening, i'm sure that my code is correct but I don't get why the linker errors returned when I changed something, then returned it back the same again. Oh and while im at it, can I return more than one thing? Because I have functions that has more than one variable that I would like to return by themselves. Or would I have to rethink that and make a new way to return more than one thing? [edited by - Nothingness on December 10, 2002 10:21:15 PM]

Try to put here your linker errors.

And instead of returning two values you can use pointers i.e.



Hope it helps.

The linker errors are:
Linking...
main.obj : error LNK2005: "int __cdecl Direction1(int)" (?Direction1@@YAHH@Z) already defined in functions.obj
main.obj : error LNK2005: "int __cdecl Direction2(int)" (?Direction2@@YAHH@Z) already defined in functions.obj
main.obj : error LNK2005: "int __cdecl Menu(class FISH)" (?Menu@@YAHVFISH@@@Z) already defined in functions.obj
Debug/main.exe : fatal error LNK1169: one or more multiply defined symbols found
Error executing link.exe.

As I said earlier I fixed it once, and then it just came back after I added something, then deleted the part I added. And everything for the .h files are good. I have the #ifndef and #elseif things, and one cpp file has the prototype and code for each function. I did everthing correct, but when I reopened the workspace and compiled it, linker errors came up.

And for the returning of 2 things I want to return 2 booleans that tell if something is TRUE or FALSE.

Do not define non-inline functions nor non-extern variables in headers.

- Header -

int foo();
inline int bar() { return 0; }
extern int baz;

- Source -

int foo() { return 0; }
int baz;
