Linuxカーネルのコンパイルが初めてで、Linuxカーネルを直接コンパイルするのは今回が初めてです（他のTCP輻輳制御アルゴリズムを使用しようとしています）。
私は次のステップに従いました。Linuxカーネルをコンパイルする方法。実行しようとすると、make次のエラーが発生します。

libelf.hから：
そしてelf.h
それから私は見つけました。以前に報告されたことしかし、まだ解決策はありません。どうですか？
答え1
実はこれは私が直接思い出したんです。コンパイラが私が考えるヘッダを見つけることができないようです。envコマンドを使用すると、CPATHが/usr/include/butにないため、次のように/home/user/.local/include:$CPATHCPATHをに変更しました。/usr/include/クレイマー、しかし、まだ動作しません。 envは、CPATHがすでにあることを示しています/usr/include/。この問題を解決するのは難しいと思います。 Ubuntuを閉じてリラックスしてください。しかし、今朝Ubuntuをオンにしましたが、すべてがうまくいきました。
