在Arch Linux上的OpenGL 3.3

I need help doing some OpenGL 3.3 programming with core profile. I'm running on an Arch Linux OS with the packages xf86-video-intel and mesa-libgl installed. I have Intel HD 4400 built into my CPU

我需要帮助做一些OpenGL 3.3的核心配置文件编程。我正在运行一个Arch Linux操作系统，并安装了xf86-video intel和mesa-libgl软件包。我的CPU内置了英特尔HD 4400。

When I enter glxinfo | grep OpenGL into terminal, It shows I can support OpenGL 3.3

当我将glxinfo | grep OpenGL输入到终端时，它显示我可以支持OpenGL 3.3

I'm using GLFW3 and GLEW to setup OpenGL

我使用GLFW3和GLEW来设置OpenGL

if(!glfwInit()) {
    return -1;
}
GLFWwindow* window = glfwCreateWindow(800, 600, "Hello Guys", NULL, NULL);
if(!window) {
    glfwTerminate();
    return -1;
}

glfwWindowHint(GLFW_CONTEXT_VERSION_MAJOR, 3);
glfwWindowHint(GLFW_CONTEXT_VERSION_MINOR, 3);
glfwWindowHint(GLFW_OPENGL_PROFILE, GLFW_OPENGL_CORE_PROFILE);
glfwWindowHint(GLFW_RESIZABLE, GL_FALSE);

glfwMakeContextCurrent(window);

if(glewInit() != GLEW_OK) {
    printf("GLEW did not initialize\n");
    glfwTerminate();
    return -1;
}

However, when I try to compile shaders, I get the error GLSL 3.30 is not supported. Supported versions are: 1.10, 1.20, 1.30, 1.00 ES, and 3.00 ES

然而，当我尝试编译着色器时，我得到错误GLSL 3.30不被支持。支持的版本有:1.10、1.20、1.30、1.00 ES和3.00 ES

It seems Mesa or GLFW3 is making my PC use the forward compatible profile instead of the core profile. How can I fix this?

似乎Mesa或GLFW3正在使我的PC使用前向兼容配置文件，而不是核心配置文件。我该怎么解决这个问题呢?

From the docs (emphasis mine):

来自文档(重点是我的):

void glfwWindowHint( int hint, int value )        
This function sets hints for the next call to glfwCreateWindow. ...

这个函数为下一次调用glfwCreateWindow设置提示。

So: unless you want the defaults make sure to set hints before you create the window:

所以:除非你想要默认设置，否则在创建窗口之前一定要设置提示:

glfwWindowHint(GLFW_CONTEXT_VERSION_MAJOR, 3);
glfwWindowHint(GLFW_CONTEXT_VERSION_MINOR, 3);
glfwWindowHint(GLFW_OPENGL_PROFILE, GLFW_OPENGL_CORE_PROFILE);
glfwWindowHint(GLFW_RESIZABLE, GL_FALSE);

GLFWwindow* window = glfwCreateWindow(800, 600, "Hello Guys", NULL, NULL);
if(!window) {
    glfwTerminate();
    return -1;
}
