opencv错误：不支持GPU

Question

I have install Cuda 6.5 and opencv 2.4.9 with visual studio 2010, when I run gpu, I get error

Opencv Error: No GPU support(the library is compiled without PGU support) in the row_nogpu, file C:/builds/2_4_Packslave-win32-vc10-shared/opencv/modules/gpu/src/precomp.hpp line 135

I get this error, is any one can help what do I have to do?

Thanks

Answer 1

I believe, you have to actually build the libraries with CUDA support. I Imagine This Guide will be useful.

Answer 2

This can be caused because of following.

1. Use the flag WITH_CUDA=ON during cmake
2. You are trying to load the libraries which are compiled without GPU support, after you install opencv make sure you change the libraries path to that of GPU supported once.
