c - 无法在 OS X 10.9 Mavericks 上针对 GLEW 构建

Question

我正在尝试在 OS X 10.9 和 Xcode 5.1 上使用 GLEW 设置一个程序，但是在尝试构建它时，我收到了大量来自 glew.h 的错误:

程序本身非常简单，仅对 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，它是从项目的 sourceforge 页面上的最新 tarball 构建的
• 我已经更改了项目中的一些build设置
  • 始终搜索用户路径 设置为 YES
  • User Header Search Paths 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。

好吧，一些深入的研究帮助我弄清楚了 Clang 到底在提示什么。看起来 Xcode 5.1 附带的 Clang 版本包括对 Modules 的支持;这非常酷和有趣，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，一切都像在以前的版本中一样工作，并且 GLEW 按预期工作。
