Error in libraries when compiling

[NikolayUvarov]

using example code from main page ubuntu 22.04/1 LTS
go version go1.21.1 linux/amd64

package main
import (
"runtime"
"time"
"github.com/micmonay/keybd_event"
)
func main() {
kb, err := keybd_event.NewKeyBonding()
if err != nil {
panic(err)
}
// For linux, it is very important to wait 2 seconds
if runtime.GOOS == "linux" {
time.Sleep(2 * time.Second)
}
// Select keys to be pressed
kb.SetKeys(keybd_event.VK_A, keybd_event.VK_B)
// Set shift to be pressed
kb.HasSHIFT(true)
// Press the selected keys
err = kb.Launching()
if err != nil {
panic(err)
}
// Or you can use Press and Release
kb.Press()
time.Sleep(10 * time.Millisecond)
kb.Release()
// Here, the program will generate "ABAB" as if they were pressed on the keyboard.
}

$ go build .

I'm getting the same error at compile time
How to fix it

Since it is directly importing C code on linux you need a compiler. Try this
sudo apt install gcc libc6-dev
Then run or build it again
