I am having issues compiling the latest OpenCV with Cuda. I get errors saying that a function body matches multiple headers. For example:

error: more than one instance of overloaded function "cv::gpu::device::color_detail::XYZ2RGBConvert" matches the argument list: function template "void cv::gpu::device::color_detail::XYZ2RGBConvert<bidx,t,d>(const T &, D *)" function template "void cv::gpu::device::color_detail::XYZ2RGBConvert<bidx,t>(const T &, float *)"

One is templated and the other isn't.

I can fix this in ../modules/gpu/src/cuda/color.cu by changing all offending lines to not implement the float, but then I later get linker errors such as:

../../lib/libopencv_gpu.so.2.4.3: undefined reference to `cv::gpu::device::yuv4_to_rgba_32f(cv::gpu::PtrStepSz<unsigned char=""> const&, cv::gpu::PtrStepSz<unsigned char=""> const&, CUstream_st*)'

For clarity, I specifically omit

OPENCV_GPU_IMPLEMENT_CVTCOLOR(name ## _32f, name ## _traits<float>)

Only on the offending lines of code in color.cu.

Any thoughts on how to fix this? If it matters, uname/lspci dump:

You are asking for argv[1] but you did not pass ./test any arguments? Also your g++ command saves to ./example not ./test. Are these typos or could that be your issue?

Just wanted to confirm that this also worked for me on Fedora 17, despite the comment saying "//"cuda" library (older versions only)." Thanks!
