Hello,

I have a very similar problem, to this clock compilation problem: http://forums.nvidia.com/index.php?showtop…rt=#entry531449

but the solution there does not help…

I am compiling with -arch=sm_20 but somehow

2>c:\cuda\include\common_functions.h(73): warning: dllexport/dllimport conflict with "printf"

2>c:\Program Files (x86)\Microsoft Visual Studio 9.0\VC\include\stdio.h(287): here; dllimport/dllexport dropped

2>slicerRenderer.cu

2>c:\visdom\views\views\slicernode\slicerRenderer_kernel.cuh(48): error: identifier "printf" is undefined

this does not solve the problem: http://forums.nvidia.com/index.php?showtop…rt=#entry531449

you can see here that both main project and nvcc use the MDd flag

Hello,

I don’t have the answer but I’m trying to make a cuda dll too…
Is there any option to configure in the cuda build rule in order to export a cuda dll?

Thanks for your answer.

Ok I have found the answer for creating a dll there is a video tutorial here :

Hope that will help ;)
