VsCode下配置OpenGL开发环境_哔哩哔哩_bilibili

环境配置

使用MinGW(非64)，安装的时候勾选base，g++和gdb

https://sourceforge.net/projects/mingw/

加入环境变量为安装路径/bin，如果以前安装过mingw64的记得要删除旧的环境变量

自己编译libglad.a 复制

项目里面的是不能直接用的

glad 在线服务 生成静态库
在压缩包执行下面的

gcc ./src/glad.c -c -I ./include/
ar -rc libglad.a glad.o

将生成的 libglad.a 复制到项目的 lib 文件下覆盖

测试运行

测试代码

#include <glad/glad.h>
#include <GLFW/glfw3.h>

#include <iostream>

void framebuffer_size_callback(GLFWwindow *window, int width, int height);
void processInput(GLFWwindow *window);

const unsigned int SCR_WIDTH = 800;
const unsigned int SCR_HEIGHT = 600;

int main()
{
    glfwInit();
    glfwWindowHint(GLFW_CONTEXT_VERSION_MAJOR, 3);
    glfwWindowHint(GLFW_CONTEXT_VERSION_MINOR, 3);
    glfwWindowHint(GLFW_OPENGL_PROFILE, GLFW_OPENGL_CORE_PROFILE);

    GLFWwindow *window = glfwCreateWindow(SCR_WIDTH, SCR_HEIGHT, "LearnOpenGL", NULL, NULL);
    if (window == NULL)
    {
        std::cout << "Failed to create GLFW window" << std::endl;
        glfwTerminate();
        return -1;
    }
    glfwMakeContextCurrent(window);
    glfwSetFramebufferSizeCallback(window, framebuffer_size_callback);

    if (!gladLoadGLLoader((GLADloadproc)glfwGetProcAddress))
    {
        std::cout << "Failed to initialize GLAD" << std::endl;
        return -1;
    }

    while (!glfwWindowShouldClose(window))
    {
        processInput(window);
        glfwSwapBuffers(window);
        glfwPollEvents();
    }

    glfwTerminate();
    return 0;
}

void processInput(GLFWwindow *window)
{
    if (glfwGetKey(window, GLFW_KEY_ESCAPE) == GLFW_PRESS)
        glfwSetWindowShouldClose(window, true);
}

void framebuffer_size_callback(GLFWwindow *window, int width, int height)
{
    glViewport(0, 0, width, height);
}

执行命令 run 编译和运行.exe 程序

make run dir=01_test_glfw

执行命令 clean 删除 .exe 和对应文件夹下的.o 文件

make clean dir=01_test_glfw
