Question

我正在尝试像这样安装opencv3：

brew install opencv3 --with-qt5 --with-opengl --with-cuda --with-ffmpeg --with-contrib

我收到此错误：

/tmp/opencv320151222-25898-1l53234/opencv-3.1.0/modules/core/src/opengl.cpp:1646:14: error: use of undeclared identifier 'clGetGLContextInfoKHR'; did you mean 'clGetContextInfo'?
        if (!clGetGLContextInfoKHR)
             ^~~~~~~~~~~~~~~~~~~~~
             clGetContextInfo
/System/Library/Frameworks/OpenCL.framework/Headers/cl.h:633:1: note: 'clGetContextInfo' declared here
clGetContextInfo(cl_context         /* context */, 
^
/tmp/opencv320151222-25898-1l53234/opencv-3.1.0/modules/core/src/opengl.cpp:1669:52: error: use of undeclared identifier 'CL_CURRENT_DEVICE_FOR_GL_CONTEXT_KHR'
        status = clGetGLContextInfoKHR(properties, CL_CURRENT_DEVICE_FOR_GL_CONTEXT_KHR, sizeof(cl_device_id), (void*)&device, NULL);

我做错了什么？

关闭With_OpenCL。

问题出现是因为您的OpenCL/cl-gl.h不包含clGetGLContextInfoKHR的声明，它实际上是可选扩展程序的一部分，并且可能无法与您的OpenCL版本一起安装。

自制软件安装opencv3 --with-contrib失败，使用未声明的标识符`clGetGLContextInfoKHR`
