Win64 GLFW未定义的引用

问题描述

我为Win64修改了我的makefile，但是在编译时出现“未定义引用”错误，这很奇怪，因为Win32 makefile上不会发生这种情况。 OpenGL库全部包含在内，我修改了库目录以指向Win64 DLL。

尽管有数以百万计的警告，GLEW仍然可以正常工作。

using namespace std;

int main() {
    // Game initialization
    if (!glfwInit()) {
        cout << "An error occurred while initializing the game. Please try again.";
        return -1;
    }
    glfwWindowHint(GLFW_RESIZABLE,GL_FALSE);
    GLFWwindow* window = glfwCreateWindow(640,480,"3D Shooter",NULL,NULL);
    glfwMakeContextCurrent(window);
    GLFWmonitor* monitor = glfwGetPrimaryMonitor();
    const GLFWvidmode* mode = glfwGetVideoMode(monitor);
    int monitorWidth = mode->width;
    int monitorHeight = mode->height;
    int windowWidth,windowHeight;
    glfwGetwindowSize(window,&windowWidth,&windowHeight);
    glfwSetwindowPos(window,(monitorWidth-windowWidth)/2,(monitorHeight-windowHeight)/2);
    while (!glfwWindowShouldClose(window)) {
        glClear(GL_COLOR_BUFFER_BIT);
        glfwSwapBuffers(window);
        glfwPollEvents();
    }
}

解决方法

我设法解决此问题，方法是切换到64位Windows，安装了64位版本的MinGW-w64，然后修改了makefile以使用“ x86_64-w64-mingw32-g ++”而不是“ i686-w64-mingw32” -g ++”。
