不具合の概要

23年5月にリリースされたRaspberry Pi OSでデバイスドライバのソースビルドに失敗します。

実行環境

$ lsb_release -a
No LSB modules are available.
Distributor ID: Raspbian
Description:    Raspbian GNU/Linux 11 (bullseye)
Release:    11
Codename:   bullseye
$ uname -a
Linux raspberrypi 6.1.21-v8+ #1642 SMP PREEMPT Mon Apr  3 17:24:16 BST 2023 aarch64 GNU/Linux

再現方法

  1. 'utils/build_install.bash ' を実行する
  2. 下記のエラーが表示される
$ ./build_install.bash 
build_install_header_from_apt_raspi4.bash

期待する動作

ビルドに成功する

その他

どうやら、Raspberry Pi 4だと、32bit版のOSをインストールしても、64bit版のカーネルが起動するようです。

/boot/config.txtにarm_64bit=0を追記して再起動しました。 デバイスドライバのビルドが始まりましたが、別のエラーが表示されます。

こちらは、#78 取り入れ済みです。
