Hi,

I want to use opencl on windows 10 My program is :

m = mOriginal + m2;

I have got an exception :

OpenCV Error: Unknown error code -220 (OpenCL error Unknown OpenCL error (999) during call: clCreateContext) in cv::ocl::Context::Impl::setDefault, file G:\Lib\opencv\modules\core\src\ocl.cpp, line 1327

I cannot find error code 999 in opencl.

Stack trace is >    opencv_core331d.dll!cv::ocl::Context::Impl::setDefault() Ligne 1326 C++

When I run exactly same program with admin right there is no error. Only difference I found is dll call : with user right C:\Windows\System32\nvptxJitCompiler.dll'. is loaded when line is executed. exception is thrown at next line.

May be it's only driver problem opencv 3.3-dev win 10 version 1703 GTX970 (driver 22.21.13.8569)

Hi,

I want to use opencl on windows 10 My program is :

m = mOriginal + m2;
ocl::setUseOpenCL(true);
