OpenCV的错误：没有GPU的支持（库不支持CUDA编译） [英] Opencv Error: no GPU support (library is compiled without CUDA support)

问题描述

我想工作，OpenCV的一些图像处理任务上与GPU CUDA。我使用Ubuntu。我安装我的两个opencv的产品和CUDA没有问题，我相信这一点。然而，当我试图在Eclipse运行示例code，我得到一个错误：

I am trying to work some image-process tasks with opencv on GPU with CUDA. I am using ubuntu. I setup my two products Opencv and Cuda without a problem, I am sure about that. However, when I attempt to run sampleCOde in eclipse, I have get an error:

OpenCV的错误：没有GPU的支持（该库不支持CUDA编译）在mallocPitch，文件/home/muad/Source/OpenCV-2.4.2/modules/core/src/gpumat.cpp ，线路749

我重拍我的OpenCV的，但我还是明白了。

I remade my opencv, but I still get that.

推荐答案

如文档中所述，您必须使用CMake的构建OpenCV的，并设置标志WITH_CUDA = ON。然后，你将获得全功能的OpenCV的GPU模块。否则，模块仍在建的，但您收到与CV_GpuNotSupported例外。

As stated in the documentation, you have to build OpenCV using CMake and set the flag WITH_CUDA=ON. Then you will get the full-featured OpenCV GPU module. Otherwise the module is still built, but you recieve an exception with CV_GpuNotSupported.
