无法在OS X 10.9 Mavericks上构建GLEW

Question

我正在尝试在OS X 10.9和Xcode 5.1上使用GLEW设置程序，但是在尝试构建它时，我得到了大量来自glew.h的错误：

该程序本身非常简单，只稍微改编自GLFW文档示例代码：

#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;
}

关于这个项目的配置，以下是一些详细信息，可能会有所帮助:

• GLEW通过Homebrew安装，从项目的sourceforge页面上构建最新的tarball
• 我已经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
  • 用户头文件搜索路径设置为/usr/local/include
• 该项目链接到libGLEW.1.10.0.dylib和libglfw.3.0.dylib

如果有人之前遇到过这个问题，或者有其他解决方案，我会非常感激。

Answer 1

好的，通过一番搜索，我弄清楚了Clang到底在抱怨什么。看起来随 Xcode 5.1 一起发布的 Clang 版本包含了对模块的支持; 这些模块非常棒和有趣，可以解决很多问题，但也会完全破坏 GLEW。

将构建选项启用模块 (C 和 Objective C) 设置为NO，就像之前的版本一样，所有东西都按预期工作并且 GLEW 也能正常工作。

Answer 2

如rpowell所提到的，避免在最近版本的XCode上出现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，通过单击其名称选择您的项目（在我的示例中为蓝色图标）

在此之后，单击“构建设置”选项卡，并确保您选择了以下选项：全部和组合。

最后，在搜索菜单中搜索“启用模块”，当出现“启用模块(C和Objective-C)”时，只需标记为不启用。

之后，您应该能够编译您的代码并使其运行。
