【问题描述】：

我正在尝试在带有 Xcode 5.1 的 OS X 10.9 上使用 GLEW 设置程序，但在尝试构建它时，我收到大量来自 glew.h 的错误：

程序本身很简单，只是对GLFW documentation's example code稍作修改：

#include <GL/glew.h>
#include <GLFW/glfw3.h>
#include <stdio.h>

int main(void)
{
    GLFWwindow* window;

    // Initialize the library
    if (!glfwInit())
        return -1;

    // Specify the minimum OpenGL version
    glfwWindowHint(GLFW_CONTEXT_VERSION_MAJOR, 3);
    glfwWindowHint(GLFW_CONTEXT_VERSION_MINOR, 2);
    glfwWindowHint(GLFW_OPENGL_PROFILE, GLFW_OPENGL_CORE_PROFILE);
    glfwWindowHint(GLFW_OPENGL_FORWARD_COMPAT, GL_TRUE);

    // Create a windowed mode window and its OpenGL context
    window = glfwCreateWindow(640, 480, "Hello World", NULL, NULL);
    if (!window)
    {
        glfwTerminate();
        return -1;
    }

    // Make the window's context current
    glfwMakeContextCurrent(window);

    printf("GL Version: %s", glGetString(GL_VERSION));

    // Loop until the user closes the window
    while (!glfwWindowShouldClose(window))
    {
        // Render here
        glClear(GL_COLOR_BUFFER_BIT);

        // Swap front and back buffers
        glfwSwapBuffers(window);

        // Poll for and process events
        glfwPollEvents();
    }

    glfwTerminate();
    return 0;
}

有关此项目配置的更多详细信息可能会有所帮助：

GLEW 是通过 Homebrew 安装的，由项目 sourceforge 页面上的最新 tarball 构建
我更改了项目中的一些构建设置
- 始终搜索用户路径设置为YES
- 用户标题搜索路径设置为/usr/local/include
项目链接到libGLEW.1.10.0.dylib 和libglfw.3.0.dylib

如果有人以前遇到过这个问题，或者有解决这个问题的方法，我将非常感激。

【解决方案1】：

好的，一些挖掘帮助我弄清楚了 Clang 到底在抱怨什么。看起来 Xcode 5.1 附带的 Clang 版本包括对Modules 的支持；这很酷很有趣，解决了一堆问题，但也完全打破了 GLEW。

通过将启用模块（C 和 Objective C） 构建选项设置为 NO，一切都像以前的版本一样工作，GLEW 也能按预期工作。

【解决方案2】：

像上面提到的 rpowell 一样，在最新版本的 XCode 上避免此错误的方法是执行以下操作： PS：（我在运行 XCode 8.2.1 和 OS X El Capitain 10.11.6 的项目中解决了这个问题）：

在“项目”选项卡上，单击项目名称选择您的项目（在我的示例中为蓝色图标）

之后，单击 Build Setting 选项卡并确保您选择了以下选项：All 和 Combined

最后，在搜索菜单中搜索“启用模块”，当它显示启用模块（C和Objective-C）时，标记为否

之后，您应该“希望”能够编译您的代码并使其运行。
