Hi,
I am using ARToolkit plus to build two AR applications: one on PC, and one
on Symbian based phone. With the PC based application, I just add
memorymanager.cpp to the project (in visual studio) to remove the common
linking error. However this method fails to work with the Symbian based
application - how should this be added properly?
Thanks
Steve

Hi, Sorry for being so vague, the error I get is the following: AR.obj : error LNK2001: unresolved external symbol "class ARToolKitPlus::MemoryManager * ARToolKitPlus::memManager" (?memManager@A ............@@3 ................@1 @A ) AR.obj : error LNK2001: unresolved external symbol "void __cdecl ARToolKitPlus::artkp_Free(void *)" (?artkp_Free@A ............@@Y .....@Z ) Thanks, Steve -----Original Message----- From: owner-artoolkit@h ..................

Second: With the current version you will probably get a very bad performance under Symbian, because ARToolKitPlus version 2 requires the Intel GPP library for fixed-point support. We'll probably release version 2.1 next week which comes with its own, purely C++ fixed point code that should work fine on any device. Now about your problem: Please be more specific about what is going wrong. Just writing "fails to work" makes it very hard to help you. I have no experience in Symian development but if you would at least post the linker error messages then I or somebody else here in the forum might be able to help you... bye, Daniel |

This is true, but I didn't think this was a problem specifically to do with Symbian - with the example supplied with ARToolkit Plus, you need to add the MemoryManager.cpp class to the visual studio workspace, otherwise you get the same error. Once you have done this, and recompile, the linker error disappears. However, doing the same in Symbian (still built using VS) produces the same error. The Globals problem doesn't exist when using the Symbian emulator - I was aiming to get the toolkit running on the emulator before tackling the global variables issue.

hi Steve, you might want to give the new ARToolKitPlus version 2.1 a try. One can now define _ARTKP_NO_MEMORYMANAGER_ which removes the global variable "memManager". Hopefully that solves your problems under Symbian. Although we don't use Symbian at our lab (and can't therefore support it) we'd be glad to put "Symbian compliance" onto our list... Daniel |
