目的
このコンパイル記録は、コンパイラおよび対応標準、コンパイラの版により、コンパイルエラーMessageの違いを記録し、どのエラーが出たら、どの版またはどの対応標準にすればエラーが少なくなるかを考察するための資料です。
成果
コンパイラの種類、対応標準の違いによってエラーの数が違う。同じエラーであってもMessageの表現が違う。Error Messageのネットで検索する際に役立つ。
背景
C++のTemplate使いこなせてない。
The Complete Guide(2nd Edition)
http://www.tmplbook.com/code/code.html
コンパイルしながら勉強。

だと, qiitaのようにコード表示機能がないためわかりにくい。
C++ Templates The Complete Guide(2nd Edition)をclang++とg++でコンパイルしてみた
https://qiita.com/kaizen_nagoya/items/a7065ea839cb33793bdf
コンパイルエラーになったものを
clang++, g++の -std=c++03, -std=c++2a
でコンパイルしながら一つづつ確認。

#まとめ
| cpp | clang++ | g++ | ||
|---|---|---|---|---|
| =-std=c++03 | =-std=c++2a | =-std=c++03 | =-std=c++2a | |
| referror2 | 15 | 17 | 30 | 20 |
##検討事項(agenda)
1)コンパイルエラーをなくす修正方法
clang++ -std=c++2aの方がエラーが多い。
2)役に立つまたは意味のあるその他の出力
