OpenCL and OpenCV conflict

In our project, we decided to port OpenCL to improve image processing. After migration, the project didn't work. So, we tried the minimal code from OpenCL and determined that if OpenCV is in use, the project doesn't work.


int main(){
  cv::Mat mat;

  std::vector<cl::Platform> all_platforms;

  std::cout <<"fertig.";
  return 0;


crash in cl :: Platform :: get ().

terminate called after throwing an instance of 'cl::Error'
what():  clGetPlatformIDs


I compiled it with

gcc test.cpp -lOpenCl -lopencv_core -lopencv_highgui


If I issue this little command line "cv :: Mat mat" everything is fine. So what's the problem?

I am using Intel OpenCl Driver: 1.2-
