<この項は書きかけです。順次追記します。>

はじめに

dockerで、gcc/gcc++, clang/clang++, vscode/vscode++を比較できるようにしたかった。

gccとclangは、gcc公式にclangを入れることで解決した。

３つを入れるのは、2019年, 2020年はうまくいかなかった。
2021年になって、落ち着いてやってみたらなんとかなった。

ここではclangを入れるところを書く。
最後に３つをいれたhubのURLを記載する。

課題は、どちらも一つのコンテナになり、更新が大規模になる点。
clangとvscodeを別々のコンテナになるようなdockerfileの記述はこれから。
よい記述がありましたら、ご紹介くださると幸いです。

過去のClangの入ったDockerに、Clangの最新版を導入しようとして失敗。

clang++ docker upgrade

素のubuntuから始めてみた。

途中でディスクが足りないと言われ、ファイルの削除、再起動などをした。
