OpenCL context does not get created
Don't really know how to word it, but long story short, I have built OpenCV from source cv::getBuildInformation() says that OpenCL is indeed installed. I have an GTX 1050, CV is also compiled with CUDA. Ubuntu 16.04. I have the same code on my work computer (has i7-4610m and AMD 8960m) CV is built from source with OpenCL and it gives me the info
Code used:
#include <opencv2/highgui/highgui.hpp>
#include <opencv2/imgproc/imgproc.hpp>
#include <iostream>
#include <opencv2/opencv.hpp>
#include <opencv2/core/ocl.hpp>
int main(int argc, char **argv)
{
cv::ocl::setUseOpenCL(true);
cv::setUseOptimized(true);
std::cout << cv::getBuildInformation() << std::endl;
if (cv::useOptimized())
{
std::cout << "using optimized" << std::endl;
}
if (!cv::ocl::haveOpenCL())
{
std::cout << "no opencl" << std::endl;
}
cv::ocl::Context context;
if (!context.create(cv::ocl::Device::TYPE_GPU)) //I've tried all of the TYPE_ they all do the same thing
{
std::cout << "failed to create" << std::endl;
}
std::cout << context.ndevices() << " GPU devices are detected." << std::endl;
std::cout << "++++++++++++++" << std::endl;
for (size_t i = 0; i < context.ndevices(); i++)
{
cv::ocl::Device device = context.device(i);
std::cout << "name: " << device.name() << std::endl;
std::cout << "available: " << device.available() << std::endl;
std::cout << "img support: " << device.imageSupport() << std::endl;
std::cout << "cl v: " << device.OpenCL_C_Version() << std::endl;
}
std::cout << "++++++++++++++" << std::endl;
std::cout << "==============" << std::endl;
cv::ocl::Device d = cv::ocl::Device::getDefault();
std::cout << d.OpenCLVersion();
std::cout << "==============" << std::endl;
}
Output of everything (not buildinfo):
using optimized
no opencl
failed to create
0 GPU devices are detected.

Let me know if you need more information Thanks in advance
