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?

BR,

Emory Freitas

there is no such thing as gpu::GpuMat in opencv3, it exists only in opencv2.4

(same problem with -lopencv_gpu - 2.4 only)

Then how can one compile a opencv3 program with cuda linkers?

sorry, if the answer was misleading, it's only about different naming between 2.4 and 3.x

thats' okay, but right now i'm finding it hard to link for opencv2/cuda.hpp. it says 'no such file or directory'. i'm using opencv3.4.2. can you help?

yea, that does no more exist. the cuda parts have been split into several cudaXXX submodules.

have a look at current docs
