Question

我正在尝试在Dev C ++上运行openGL。我无法运行代码。我已尝试过这个网站上的所有内容：

http://www.prinmath.com/csci5229/misc/DevC_OpenGL_for_Windows.pdf

我的操作系统是Windows 7-64位。如果可以，我会使用不同的IDE，但我的学校坚持使用Dev C ++。

这是我要尝试运行的代码：

#include <GL/gl.h>
#include <GL/glu.h>
#include <GL/glut.h>    


void init()
{
    glClearColor (1.0, 1.0, 1.0, 0.0); 

    glMatrixMode (GL_PROJECTION);       
    gluOrtho2D (0.0, 200.0, 0.0, 200.0); 
}

void lineSegment()
{
    glClear (GL_COLOR_BUFFER_BIT);  // Clear display window. color buffer

    glColor3f (0.0, 0.0, 0.0);     
int p1 [ ] = {40,80};
int p2 [ ] = {160, 80};
int p3 [ ] = {100, 40};
int p4 [ ] = {100, 160};
int p5 [ ] = {0, 80};
int p6 [ ] = {200, 200};
int p7 [ ] = {100, 0};
int p8 [ ] = {100,200 };
int p9 [ ] = {30, 30};
int p10 [ ] = {0, 0};

glBegin(GL_LINE_LOOP);
glVertex2iv(p1);
glVertex2iv(p2);
glVertex2iv(p3);
glVertex2iv(p4);

    glFlush ( );     
}

int main(int argc, char *argv[])
{
    glutInit (&argc, argv);                         // Initialize GLUT.
    glutInitDisplayMode (GLUT_SINGLE | GLUT_RGB);   // Set display mode, single buffering.
    glutInitWindowPosition (50, 100);   // Set top-left display-window position.
    glutInitWindowSize (400, 300);      // Set display-window width and height.
    glutCreateWindow ("An Example OpenGL Program"); // Create display window.

    init( );                            // Execute initialization procedure.
    glutDisplayFunc (lineSegment);       // Send graphics to display window.
    glutMainLoop ( );                    // Display everything and wait.

    //return EXIT_SUCCESS();
    return 0;   
}

以下是我尝试编译时编译日志所说的内容：

看起来你正在使用错误版本的C-runtime（CRT）进行链接。

如果您安装了多个版本的MinGW，请显示Dev-C ++在哪里找到正确的包含和库（检查您的PATH环境变量，MINGW_HOME环境变量和Dev-C ++编译器选项）。您必须使用随编译器提供的CRT。
在其他包含之前尝试#include <windows.h>。它可以修复dllimports内容
尝试将-m32标志添加到编译器命令行（如果您使用64位编译器进行编译，它将为x86_32发出代码）
问你的老师如何解决这个问题（这是他（她）的工作，而且他选择使用10年的工作）

请注意，Dev-C++ was released 22.02.2005的最新版本。它包括GCC 3.4.2 released September 6, 2004。你必须真的问你的老师为什么他们会坚持使用9岁的IDE和10年的编译器。你可以找到Dev-C ++ here的维护版本（它被其他开发人员选中）和最新的MinGW编译器here。
