vscode_OpenGL_undefined_reference_to_glfwInit_2">Win vscode 配置OpenGL时 undefined reference to `glfwInit’

现象

win 上面用vscode 配置OpenGL 时会报一下错误

g++ -std=c++17 -Wall -Wextra -g -Iinclude -o output\main.exe src/main.o  -Llib -lglad -lglfw3

原因

是因为vscode中使用了MinGW中g++作为项目的编译器，和下载的预编译glfw-3.4.bin.WIN64\lib-mingw-w64中的libglfw3.a不兼容导致的。

解决方案

下载glfw源码，使用MinGW中的g++自己编译出来的libglfw3.a放进自己项目的 lib文件夹中
