c++ - OpenCL:无效值

Question

我在 windows 中填充 cl_context_propeties 时遇到问题:

这是我的代码:

cl_context_properties props[] = {
    CL_GL_CONTEXT_KHR,
    (cl_context_properties)wglGetCurrentContext,
    CL_WGL_HDC_KHR,
    (cl_context_properties)wglGetCurrentDC,
    CL_CONTEXT_PLATFORM,
    (cl_context_properties)platform,
};
*context = clCreateContextFromType(props, CL_DEVICE_TYPE_GPU, NULL, NULL, &err);

在这些行之后是我的错误中的错误代码 -30(CL_INVALID_VALUE 的错误代码中为 -30)

有人想解决我的问题吗？

您需要调用函数并以零结束。试试这个:

cl_context_properties props[] = {
  CL_GL_CONTEXT_KHR, (cl_context_properties) wglGetCurrentContext (),
  CL_WGL_HDC_KHR, (cl_context_properties) wglGetCurrentDC (),
  CL_CONTEXT_PLATFORM, (cl_context_properties) platform,
  0 
};
