libopencv_gpu is not available

I have installed OpenCV-3.0 in my jetson-tk1 board using following cmake command.

cmake -DWITH_CUDA=ON -DCUDA_ARCH_BIN="3.2" -DCUDA_ARCH_PTX="" -DBUILD_TESTS=OFF -DBUILD_PERF_TESTS=OFF ..

After make install, I was not able to find libopencv_gpu.

In opencv lib path libopencv_gpu is not available.

Due to this I am getting undefined reference to cv::gpu::GpuMat::upload()

Can anybody tell what is the problem ?

OpenCV3.0 has merged gpu module into cuda namespace. Try using cv::cuda::GpuMat. Moreover, make sure you add opencv2/core/cuda.hpp and link cuda libraries in the linker.

For further reference you can check this documentation

In OpenCV 3.0 gpu module was split onto several modules: cudaarithm, cudafilters, cudaimgproc, cudaoptflow, etc. Also gpu namespace was renamed to cuda.

So you need to link with libopencv_core, which contains GpuMat definition and with other cuda modules: libopencv_cudaarithm, etc.
