Exporting classes from a DLL

[Zaei]

This is probably something stupid, but I dont know.

I am trying to export a class from a DLL. Inside of the class is a custom templated queue class. When I compile, I get a warning saying:

c:\divinity\classes\cobject.h(94) : warning C4251: 'MsgQueue' : class 'Queue<struct DMSG>' needs to have dll-interface to be used by clients of class 'CObject'

I have tried adding __declspec(dllexport) to my Queue class, etc. Also, the application using it works just fine. I just want to get rid of the warning. Any ideas?

You can't export a template, but you can export a specialisation of it

Basically...did you set your project options to use the runtime library as a DLL rather than a static library?

I just left it as whatever the default is. Should I just convert my template to a regular class? It isnt used for anything else...

If you think about it logically, it's pointless exporting a template since it's only a template as far as the compiler is concerned - it's used for conditional code generation.

I made that mistake before

Alrighty, conversion time =).

Thanks much!
