Description

Hi,

I'm building latest opencv 3.0 from source with CUDA SDK 5.5. My graphics card is Gigabyte NVidia GeForce 9800GTX+ with 1.1 computability. When building opencv_core module, i get this error:

"*nvcc : fatal error : nvcc supports '--relocatable-device-code=true (-rdc=true)' , '--device-c (-dc)' and '--device-link (-dlink)' only when targeting sm_20 or higher*"

CMake settings:
CUDA_ARCH_BIN: 1.1 1.2 1.3 2.0 2.2(2.0) 3.0.3.5
CUDA_ARCH_PTX: 3.0

Enviroment and tools:
Visual Studio C++ 2012
Windows 7

I changed CUDA_ARCH_BIN and CUDA_ARCH_PTX but i seems that doesn't affect.

Is it possible a bug?

Since 3.0 is a development branch OpenCV does not guarantee it will build without problems. I experience similar GPU building problems with 3.0 compute capability, seems this is indeed an unfixed bug!

Do you know how to fix it?
