Squirrel

Hello,

I seem to be having some problems with SqPlus when pushing a custom class to the script.
I can define it fine and it works when i do 'local vec = Vector( 0.0, 0.0, 0.0 );'
But when i come to doing Push( v, vec ); in C++ i get this error:

error LNK2019: unresolved external symbol "void __cdecl SqPlus::Push(struct SQVM *,class Vector &)" (??$Push@VVector@@@SqPlus@@YAXPAUSQVM@@AAVVector@@@Z) referenced in function "public: static int __cdecl CSQPlayerFuncs::GetPos(struct SQVM *)" (?GetPos@CSQPlayerFuncs@@SAHPAUSQVM@@@Z) SQPlayerFuncs.obj


I am using the latest SqPlus from the SVN repository and Squirrel 3.0 Alpha 1 and compiling using Visual Studio 2005

Any help would be greatly appreciated

You have not generated bodies for the functions requested by the linker.
 In your source file you need

  DECLARE_INSTANCE_TYPE(Vector)
  // ... and so one for whatever classes you bind.

This macro generates the functions the linker asks for.

It's not enough with only SQClassDef<Vector>...

I've already added that and still getting the same error. Anything else i may have missed?

You have to follow the code in sqplus.h a bit.

DECLARE_INSTANCE_TYPE results in DECLARE_INSTANCE_TYPE_NAME_
and this generates two Push functions, matching the ones your linker is asking for.

To clarify a compiler/link problem involving macros, it is sometimes helpful to expand
macros manually into ones source file, so one can see exactly where the problem is.

There could be some issue with name-spaces also.

There are useful examples in the testSqPlus2Unit folder.

I feel like such a fool... i had the DECLARE_INSTANCE_TYPE inside a cpp file instead of the main header file i was linking against >
I realised when i was breaking it all down.

Thanks for your help :)
