在Cygwin下编译最小的GLEW应用程序

在Cygwin下编译最小的GLEW应用程序，首先需要确保已经安装了Cygwin以及相关的开发工具和库。以下是一个简单的GLEW应用程序示例：

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

int main() {
    if (!glfwInit()) {
        return -1;
    }

    GLFWwindow* window = glfwCreateWindow(640, 480, "Hello World", NULL, NULL);
    if (!window) {
        glfwTerminate();
        return -1;
    }

    glfwMakeContextCurrent(window);
    GLenum err = glewInit();
    if (GLEW_OK != err) {
        fprintf(stderr, "Error: %s\n", glewGetErrorString(err));
        return -1;
    }

    while (!glfwWindowShouldClose(window)) {
        glClear(GL_COLOR_BUFFER_BIT);
        glfwSwapBuffers(window);
        glfwPollEvents();
    }

    glfwTerminate();
    return 0;
}

要编译这个程序，首先需要安装相关的库和头文件。在Cygwin中，可以使用以下命令安装所需的库和头文件：

$ cygwin-setup.exe -q -P libglew-devel -P libglfw3-devel -P libglu-devel -P libgl-devel -P libx11-devel -P libxrandr-devel -P libxinerama-devel -P libxi-devel -P libxcursor-devel -P libxrender-devel -P libxext-devel -P libxfixes-devel -P libxxf86vm-devel -P libxss-devel -P libxau-devel -P libxdmcp-devel -P libxcb-devel -P libx11-xcb-devel -P libxkbfile-devel -P libxcb-xkb-devel -P libxkbcommon-devel -P libxkbcommon-x11-devel -P libxkbcommon-xcb-devel -P libxkbcommon-x11-xkb-devel -P libxkbcommon-xcb-xkb-devel -P libxkbcommon-x11-xkb-devel -P libxkbcommon-xcb-xkb-devel -P libxkbcommon-x11-xkb-devel -P libxkbcommon-xcb-xkb-devel -P libxkbcommon-x11-xkb-devel -P libxkbcommon-xcb-xkb-devel -P libxkbcommon-x11-xkb-devel -P libxkbcommon-xcb-xkb-devel -P libxkbcommon-x11-xkb-devel -P libxkbcommon-xcb-xkb-devel -P libxkbcommon-x11-xkb-devel -P libxkbcommon-xcb-xkb-devel -P libxkbcommon-x11-xkb-devel -P libxkbcommon-xcb-xkb-devel -P libxkbcommon-x11-xkb-devel -P libxkbcommon-xcb-xkb-devel -P libxkbcommon-x11-xkb-devel -P libxkbcommon-xcb-xkb-devel -P libxkbcommon-x11-xkb-devel -P libxkbcommon-xcb-xkb-devel -P libxkbcommon-x11-xkb-devel -P libxkbcommon-xcb-xkb-devel -P libxkbcommon-x11-xkb-devel -P libxkbcommon-xcb-xkb-devel -P libxkbcommon-x11-xkb-devel -P libxkbcommon-xcb-xkb-devel -P libxkbcommon-x11-xkb-devel -P libxkbcommon-xcb-xkb-devel -P libxkbcommon-x11-xkb-devel -P libxkbcommon-xcb-xkb-devel -P libxkbcommon-x11-xkb-devel -P libxkbcommon-xcb-xkb-devel -P libxkbcommon-x11-xkb-devel -P libxkbcommon-xcb-xkb-devel -P libxkbcommon-x11-xkb-devel -P libxkbcommon-xcb-xkb-devel -P libxkbcommon-x11-xkb-devel -P libxkbcommon-xcb-xkb-devel -P libxkbcommon-x11-xkb-devel -P libxkbcommon-xcb-xkb-devel -P libxkbcommon-x11-xkb-devel -P libxkbcommon-xcb-xkb-devel -P libxkbcommon-x11-xkb-devel -P libxkbcommon-xcb-xkb-devel -P libxkbcommon-x11-xkb-devel -P libxkbcommon-xcb-xkb-devel -P libxkbcommon-x11-xkb-devel -P libxkbcommon-xcb-xkb-devel -P libxkbcommon-x11-xkb-devel -P libxkbcommon-xcb-xkb-devel -P libxkbcommon-x11-xkb-devel -P libxkbcommon-xcb-xkb-devel -P libxkbcommon-x11-xkb-devel -P libxkbcommon-xcb-xkb-devel -P libxkbcommon-x11-xkb-devel -P libxkbcommon-xcb-xkb-devel -P libxkbcommon-x11-xkb-devel -P libxkbcommon-xcb-xkb-devel -P libxkbcommon-x11-xkb-devel -P libxkbcommon-xcb-xkb-devel -P libxkbcommon-x11-xkb-devel -P libxkbcommon-xcb-xkb-devel -P libxkbcommon-x11-xkb-devel -P libxkbcommon-xcb-xkb-devel -P libxkbcommon-x11-xkb-devel -P libxkbcommon-xcb-xkb-devel -P libxkbcommon-x11-x
