I hope this can be helpful.

2017-07-25 09:24:22 -0500 asked a question Opencv 3.2 with Cuda 8.0

Hello everyone,

I am trying to implement an application with CUDA 8.0, at the momment I am trying to implement in my machine x84_64 and then using a cross-compile to my Jetson TX1

I already download and install opencv from git and install with CUDA 8.0

When I use cv::cuda::GpuMat is working, but when I try tu use cv::gpu:GpuMat I get the error below:

undefined reference to `cv::gpu::GpuMat::release()'

I looked up at some blogs and others site that is missing lopencv_gpu but when I use pkg-config I cannot find this library in OPencv libs.

By the way, I found this library when use command "whereis opencv_gpu" and get the answer to opencv2.

Could anyone help me, please?
