DeepCL: Seg Fault on ClBlasInstance();

Hello! I got a segfault on ClBlasInstance();

on this piece of code: ` cl_int ret; cl_uint numberPlatform;

ret = clGetPlatformIDs(0, NULL, &numberPlatform);

if (ret != CL_SUCCESS || numberPlatform == 0) {
    return  0;
} `

ret = clGetPlatformIDs(0, NULL, &numberPlatform); - crashes.

This piece of code is working fine outside of library, but in lib it is crashes.

OpenCL installed. CUDA installed. Ubuntu 16.04.

You also need to create an OpenCL context, before instantiating a ClBlasInstance instance;. By the way ClBlasInstance is not really a method, it’s an object. Can you put the following at the start of your main, and remove the call to ClBlasInstance?

    EasyCL *cl = 0;
    if(config.gpuIndex >= 0) {
        cl = EasyCL::createForIndexedGpu(config.gpuIndex);
    } else {
        cl = EasyCL::createForFirstGpuOtherwiseCpu();
    }
    ClBlasInstance blasInstance;
