Question

我正在Mac上学习OpenGL，在它可以正常工作的情况下，我试图在VirtualBox虚拟机上的Linux Mint 17.3上重新创建程序。

听说我只需要g ++，make，freeglut3-dev和文本编辑器，我相信我已经拥有了所有这些。例如，如果我做sudo apt-get install g++，它会说g++ is already the newest version，其余的也一样。

我写了一个简单的程序：

#include <GL/freeglut.h>
#include <GL/gl.h>

void renderFunction() {
    glClearColor(0.0, 0.0, 0.0, 0.0);
    glClear(GL_COLOR_BUFFER_BIT);
    glColor3f(1.0, 1.0, 1.0);
    glOrtho(-1.0, 1.0, -1.0, 1.0, -1.0, 1.0);
    glBegin(GL_POLYGON);
    glVertex2f(-0.5, -0.5);
    glVertex2f(-0.5, 0.5);
    glVertex2f(0.5, 0.5);
    glVertex2f(0.5, -0.5);
    glEnd();
    glFlush();
}

int main(int argc, char** argv) {
    glutInit(&argc, argv);
    glutInitDisplayMode(GLUT_SINGLE);
    glutInitWindowSize(500,500);
    glutInitWindowPosition(100,100);
    glutCreateWindow("OpenGL - First window demo");
    glutDisplayFunc(renderFunction);
    glutMainLoop();  

return 0;
}

编译命令g++ opengl.c -lglut -lGL -lGLEW -lGLU -o opengl似乎有效。但是当我运行./opengl时，会收到大量错误消息：

我不知道这意味着什么或如何处理。

OpenGL依赖图形驱动程序。 VirtualBox没有最新，有效的驱动程序。最好的办法是安装来宾添加。 Freeglut也不起作用，最有希望的是仅使用glad和GLFW手工编写所需的最少代码。但是不要期望太多，当然也不要“测试我的程序的可移植性”。

几次尝试后，我曾经设法通过一些实验性台面驱动程序使OpenGL 3.3在特定版本的Ubuntu上运行，但是我不知道如何可靠地重现该版本。 askubuntu上的问题几乎相同。
