Can some one please guide me compiling a sample code, which loads and display an image. Code is written using OpecnCV libraries and certain CUDA properties.
nvcc `pkg-config --libs opencv` -L. -L/usr/local/cuda/lib -lcuda -lcudart `pkg-config --cflags opencv` -I. -I/usr/local
/cuda/include LoadDisplayImageViaGPU.cu -o LoadDisplayImageViaGPU.out
Above given is the way how I tried to compile. It gave me following errors.
