C++ Templates The Complete Guide(2nd Edition) (3)basics/referror2.cpp

More than 1 year has passed since last update.


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。


勉強の記録

https://researchmap.jp/joqzln3gi-1797580/#_1797580

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。


clang++

clang version 6.0.0 (tags/RELEASE_600/final)

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
