経緯
とあるデバイスのドライバを入れたいのに、dkmsするとエラーを吐いてしまう。
ログを見たらカーネルヘッダのファイルが不足している模様。
結果
- aptでカーネルヘッダ入れたときのコンパイルが失敗している
-
make scriptsでclassmap.hが無いと怒られる - scriptsのMakefileの
subdir-$(CONFIGS_SECURITY_SELINUX) += selinuxをコメントアウト - めでたしめでたし？

/usr/src/linux-headers-4.4.180-rockchip64の/scripts/recordmcountが無いらしい。
- ソースファイルがあるけどバイナリがないっぽい
$ pwd

$ ls recordmcount*

- もう一回ここだけmakeしてみるが
classmap.hとは…
