I want to create CUDA library in other program but found below errors:
It is further found that CUDA Program use only the library created by the Cuda Wizard.
If i tried to use the library (generatd by cuda) in c++ project then below error is coming:

Thanks in advance…
You have a runtime library mismatch, some files are being compiled with /MT and some with /MD (or the debug variants). Then the linker tries to link to both libraries and you get conflicts.
Make sure all files are compiled with /MT (/MTd for debug builds)

The lib built was OK. But i am getting follwoing errors when i try to built the main exe.
Thanks Nabarun.
It looks like you’re not linking cudart.lib
Mac,
It is there in COnfigeration Properties->Linker->Input->Additional Dependencies->cudart.lib cutil64D.lib.
Anything else that i need to do.
Well i made some changes and it is working now but with dynamic linker.
Static linker is still a problem.
What do you mean by dynamic and static linker?
Also, make sure you’re linking to cudart.lib from CUDA/lib64, not CUDA/lib if you’re building a 64 bit app. Cutil libs are marked with 32 or 64, cudart libs are not. This might be an issue if, for example, you have CUDA/lib on the library search path (Tools->Options->Projects and solutions->VC++ Directories) or generally if the linker finds the 32 bit library before the 64.
