一. 安装GLAD头文件及动态库
|
1 2 3 |
git clone https://github.com/Dav1dde/glad.git |
|
1 2 3 4 5 6 7 8 |
cd glad git checkout c gcc -fpic src/glad.c -c gcc -shared -Wl,-z,relro,-z,now -o libglad.so glad.o sudo cp libglad.so /usr/lib/ sudo cp include/* -r /usr/include |
二. 安装glfw3库
Arch+x11直接安装glfw-x11，其他版本桌面服务器的请再自行网上查阅
|
1 2 3 |
sudo pacman -S glfw-x11 |
三. 实例

编译:
|
1 2 3 |
gcc -lglfw -lglad hello.c |
注意不是-lglfw3，带上3就报错了
运行
|
1 2 3 |
./a.out |
现象就是一个打开的窗口而已
sudo pacman -S glad
