MinGW找不到OpenGL命令

我在编译我的使用OpenGL的C++应用程序。所有包括在里面，libopengl32.a和libglu.a都在我的MinGW lib文件夹中。我的OpenGL的C++文件看起来是这样的：MinGW找不到OpenGL命令

#include <GL/gl.h> 
#include <GL/glu.h> 
#include <pthread.h> 
#include <windows.h> 

#include "GL.h" 

//using namespace std; 

HDC hDC; 
PIXELFORMATDESCRIPTOR pfd; 
HGLRC hRC; 

BOOL ren = false; 
pthread_t t; 

void initGL(HWND hWnd) 
{ 
    hDC = GetDC(hWnd); 
    ReleaseDC(hWnd, hDC); 

    pfd.nSize = sizeof(pfd); 
    pfd.nVersion = 1; 
    pfd.dwFlags = PFD_DRAW_TO_WINDOW | PFD_SUPPORT_OPENGL | PFD_DOUBLEBUFFER; 
    pfd.iPixelType = PFD_TYPE_RGBA; 
    pfd.cColorBits = 24; 
    pfd.cDepthBits = 16; 
    pfd.iLayerType = PFD_MAIN_PLANE; 
    int iFormat = ChoosePixelFormat(hDC, &pfd); 
    SetPixelFormat(hDC, iFormat, &pfd); 

    hRC = wglCreateContext(hDC); 
} 

void destroyGL() 
{ 
    wglDeleteContext(hRC); 
} 

void renderGL() 
{ 
    wglMakeCurrent(hDC, hRC); 

    glClearColor(0.0f, 0.0f, 0.0f, 0.0f); 
    glClear(GL_COLOR_BUFFER_BIT); 

    glBegin(GL_TRIANGLES); 
    glColor3f(1.0f, 0.0f, 0.0f); glVertex2f(0.0f, 1.0f); 
    glColor3f(0.0f, 1.0f, 0.0f); glVertex2f(0.87f, -0.5f); 
    glColor3f(0.0f, 0.0f, 1.0f); glVertex2f(-0.87f, -0.5f); 
    glEnd(); 
    glPopMatrix(); 

    SwapBuffers(hDC); 

    wglMakeCurrent(NULL, NULL); 
} 

void *RenderLoop(void *args) 
{ 
    while(ren) 
    { 
     renderGL(); 
    } 
    return 0; 
} 

void StartRender() 
{ 
    ren = true; 
    pthread_create(&t, NULL, RenderLoop, NULL); 
} 

void StopRender() 
{ 
    ren = false; 
}

的代码看起来不错，但是当我编译它，我得到这个：

GL.cpp:(.text+0x1c): undefined reference to `_imp____glutInitWithExit 
GL.cpp:(.text+0x3e): undefined reference to `_imp____glutCreateWindow

GL.cpp:(.text+0x282): undefined reference to `[email protected]' 
GL.cpp:(.text+0x2dd): undefined reference to `_imp__pthread_create'

我编译我的代码是这样的：

windres res.rc -o res.o 
g++ -static -static-libgcc -static-libstdc++ -s -mwindows -c win.cpp GL.cpp 
g++ -static -static-libgcc -static-libstdc++ -s -mwindows -lopengl32 -lglu32 win.o GL.o res.o -o bin/win.exe

你记得链接'opengl32.lib'吗？ – Vallentin

它不存在于我的电脑 – Hullu2000

那么，那绝对是主要问题！ – Vallentin

看来g ++没有找到两个库中的任何一个。尝试使用-L选项明确提供您在g ++命令中需要的.a文件的目录。
