Failed to link whem trying to flash code to esp32 with tinygo

Question

I'm trying to make a simple Hello World with tinygo and esp32, but I get an error when I upload it. In that context, a hello world would be a led blink.

`

package main

import (
    "machine"
    "time"
)

func main() {
    println("START")

    var pin machine.Pin = 2
    pin.Configure(machine.PinConfig{Mode: machine.PinOutput})

    for {
        pin.Low()
        time.Sleep(time.Millisecond * 500)

        pin.High()
        time.Sleep(time.Millisecond * 500)
    }
}

`

to upload it to the esp32, I'm using:

tinygo flash -target=esp32-coreboard-v2 -port=/dev/ttyUSB0 test1.go

(test1 is the name of the file). Then the following error occurs:

`error: failed to link /tmp/tinygo456060352/main: exec: "xtensa-esp32-elf-ld": executable file not found in $PATH

How can I fix it ?`

I tried exposing the global path and changing the usb port of the esp32. I was expecting that the code would be uploaded.
