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。
C++ Templates The Complete Guide(2nd Edition)をclang++とg++でコンパイルしてみた

背景
C++のTemplate使いこなせてない。

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 | =-std=c++03 | =-std=c++2a | =-std=c++03 | =-std=c++2a |
projectioniterator | 5 | 5 | 8 | 8 |
検討事項(agenda)
1)コンパイルエラーをなくす修正方法
g++の方がclang++よりエラーが多い。
2)役に立つまたは意味のあるその他の出力
