C++ Struct Calling Confusion

-----------------------------------

Alright,

I'm getting errors and it's confusing me on how to declare and pass a struct.

http://pastebin.ca/1315254

The error I'm getting is:

1>------ Build started: Project: Workshop2, Configuration: Debug x64 ------
1>Compiling...
1>libpos.cpp
1>.\libpos.cpp(24) : error C2027: use of undefined type 'POS'
1>        d:\devel\c++\workshop2\workshop2\pointofsales.h(19) : see declaration of 'POS'
1>.\libpos.cpp(24) : error C2228: left of '.taxable' must have class/struct/union
1>.\libpos.cpp(25) : error C2027: use of undefined type 'POS'
1>        d:\devel\c++\workshop2\workshop2\pointofsales.h(19) : see declaration of 'POS'
1>.\libpos.cpp(25) : error C2228: left of '.ftax' must have class/struct/union
1>.\libpos.cpp(25) : error C2676: binary '

Please help.

Thanks,

could you show me a copy of the code that you tried to compile (or is that what the link you provided is for?)

the link shows the code.

and it's an Not For Work code (since some guy told me it's a requirement for GPL'd code here....)

Thanks,

k, i think ur problem is this :


        struct POS sales;


it should instead be :


        POS sales;

-----------------------------------

nevermind, I fixed it with my friend's suggestion.

Just by moving the struct to the header, it fixed it.

Now, I'm getting another LNK2019 error.

1>pointofsales.obj : error LNK2019: unresolved external symbol "void __cdecl posmath(struct POS,int *,double *,double *)" (?posmath@@YAXUPOS@@PEAHPEAN2@Z) referenced in function "void __cdecl initPOS(void)" (?initPOS@@YAXXZ)
1>D:\devel\c++\Workshop2\x64\Debug\Workshop2.exe : fatal error LNK1120: 1 unresolved externals

This error message is telling you it can't find the method:
void posmath ( struct POS , int *, double *, double *)

Where is that function declared, where is it defined? Are you sure both are being included properly? Are you sure the argument lists match exactly?
