Question

我正在尝试在我的Mac上编译OpenGL + OpenCL代码并经过大量努力设法安装依赖项并了解如何链接它们（GLUI，GLUT，OpenCL等）。

大部分错误已被删除，但仍有3个错误仍然存在，如下所示：

pranjal:~/parallel-prog$ g++-4.9 mittalp.cpp -fopenmp -framework OpenCL -framework OpenGL -framework GLUI -framework GLUT -w

mittalp.cpp: In function 'void InitCL()':
mittalp.cpp:465:69: error: 'wglGetCurrentContext' was not declared in this scope
   CL_GL_CONTEXT_KHR,  (cl_context_properties) wglGetCurrentContext( ),
                                                                     ^
mittalp.cpp:466:62: error: 'wglGetCurrentDC' was not declared in this scope
   CL_WGL_HDC_KHR,   (cl_context_properties) wglGetCurrentDC( ),
                                                              ^
mittalp.cpp: In function 'void InitGlui()':
mittalp.cpp:619:37: error: 'FALSE' was not declared in this scope
   Glui->add_column_to_panel( panel, FALSE );
                                     ^

我尝试了所有我知道的编译器标志，并且无法编译。该代码在朋友的机器上在Windows上运行良好，但它在我的Mac OS X上不起作用。我怀疑错误是因为错误中列出的3个函数是特定于窗口的。由于我是OpenGL编程的新手，我对OS X等效函数知之甚少，或者我的Mac上需要哪些库才能使这些特定于Windows的函数有效。

我添加了C ++代码here以供参考：

这是我用来初始化OpenCL上下文属性以在Windows，OS X和Linux上启用OpenGL互操作性的代码：

#if defined(_WIN32)

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

#elif defined(__APPLE__)

    // OS X                                                                     
    CGLContextObj     kCGLContext     = CGLGetCurrentContext();
    CGLShareGroupObj  kCGLShareGroup  = CGLGetShareGroup(kCGLContext);

    cl_context_properties properties[] = {
      CL_CONTEXT_PROPERTY_USE_CGL_SHAREGROUP_APPLE,
      (cl_context_properties) kCGLShareGroup,
      0
    };

#else

    // Linux                                                                    
    cl_context_properties properties[] = {
      CL_GL_CONTEXT_KHR, (cl_context_properties)glXGetCurrentContext(),
      CL_GLX_DISPLAY_KHR, (cl_context_properties)glXGetCurrentDisplay(),
      CL_CONTEXT_PLATFORM, (cl_context_properties)platform,
      0
    };

#endif
