Kompilieren der milkv-duo-examples Beispielprogramme

Zuerst die notwendigen Abhängigkeiten installieren:

bash

$ ruyi install gnu-milkv-milkv-duo-musl-bin

Entpacken und Kompilieren der milkv-duo-examples:

bash

$ mkdir test-duo-examples

$ cd test-duo-examples

$ ruyi extract milkv-duo-examples

Ändern Sie den Inhalt der envsetup.sh:

bash

#!/bin/bash

script_dir=$(cd -- "$(dirname -- "${BASH_SOURCE[0]}")" &> /dev/null && pwd)

echo "script_dir: ${script_dir}"

Starten der virtuellen Umgebung:

bash

$ source envsetup.sh

Der Build-Vorgang sollte nun erfolgreich sein:

bash

$ cd i2c/ssd1306_i2c

$ make
