Raspberry
Piにmt7601uチップを搭載したwifi子機を付けて、アクセスポイントを作ろうと思ったのですが、どうやらドライバーが必要なようで、ビルドしようとしたのですが、

```

```

という感じでエラーが表示されてしまいました。  
因みに、ラズパイは最新の状態にしてあります。  
助けてください。

question
linux raspberry-pi raspbian
mt7601u-ap ドライバーをRaspberry Piにインストールしたい。
エラーメッセージのところ

> make -C /lib/modules/4.14.50-v7+/build SUBDIRS=/home/pi/mt7601u-ap/os/linux
> modules  
>  make[1]: * /lib/modules/4.14.50-v7+/build: No such file or directory. Stop.

1行目は、torisoboroさんが入力したコマンド。  
その内容は、makeコマンドに-Cオプション(makeの動作を始めるにあたって、指定されたディレクトリに移動する）が使われていて、移動先として
/lib/modules/4.14.50-v7+/build が指定されています。

しかし、/lib/modules/4.14.50-v7+/buildというディレクトリが存在しないので"No such file or
directory"というエラーが出力されただけで終わっています。

問題は、/lib/modules/4.14.50-v7+/buildという存在しないディレクトリを指定した事です。  
正しいディレクトリを指定すれば、makeが正しく動作するのではないかと思われます。

answer
`/lib/modules/4.14.50-v7+/build` が存在しないのは、おそらく kernel module
のビルド環境をインストールしていないからだと思います。

使っている OS に kernel module ビルド環境のパッケージがあるはずですので、それをインストールしてください。Raspbian
であれば、README.md に書いてある通りでできると思います。
