はじめに(Introduction)

N4910 Working Draft, Standard for Programming Language C++

C++ n4910は、ISO/IEC JTC1 SC22 WG21の作業原案(Working Draft)です。
公式のISO/IEC 14882原本ではありません。
ISO/IEC JTC1 SC22 のWG21を含むいくつかのWGでは、可能な限り作業文書を公開し、幅広い意見を求めています。

ISO/IEC JTC1 SC7からISO/IEC JTC1 SC22リエゾンとして、2000年頃、C/C++の品質向上に貢献しようとした活動をしていたことがあります。その頃は、まだISO/IEC TS 17961の原案が出る前です。Cの精神が優勢で、セキュリティ対策は補助的な位置付けでした。ISO/IEC TS 17961の制定と、C/C++のライブラリ類の見直しと、C++の進化はどんどん進んでいきます。 

進化の具合が、どちらに行こうとしているかは、コンパイルて実行させてみないとわかりません。C/C++の規格案の電子ファイルは、そのままコンパイルできる形式であるとよいと主張してきました。MISRA-C/C++, CERTC/C++でも同様です。MISRA-C/C++は、Example Suiteという形で、コード断片をコンパイルできる形で提供するようになりました。

一連の記事はコード断片をコンパイルできる形にする方法を検討してコンパイル、リンク、実行して、規格案の原文と処理系(g++, Clang++)との違いを確認し、技術内容を検討し、ISO/IEC JTC1 SC22 WG21にフィードバックするために用います。
また、CERT C++, MISRA C++等のコーディング標準のコード断片をコンパイルする際の参考にさせていただこうと考えています。CERT C++, MISRA C++が標準化の動きとの時間的なずれがあれば確認できれば幸いです。また、boostライブラリとの関連、Linux OS, 箱庭プロジェクト、g++(GCC), clang++(LLVM)との関係も調査中です。
何か、抜け漏れ、耳より情報がありましたらおしらせくださると幸いです。

<この項は書きかけです。順次追記します。>

背景(back ground)

C/C++でコンパイルエラーが出ると、途方にくれることがしばしばあります。
何回かに1回は、該当するエラーが検索できます。
ただ、条件が違っていて、そこでの修正方法では目的を達成しないこともしばしばです。いろいろな条件のコンパイルエラーとその対応方法について、広く記録することによって、いつか同じエラーに遭遇した時にやくに立つことを目指しています。

この半年の間で、三度、自分のネットでの記録に助けられたことがあります。
また過去に解決できなかった記録を10種類以上、最近になって解決できたことがあります。それは、主に次の3つの情報に基づいています。

cpprefjp - C++日本語リファレンス

コンパイラの実装状況

また
https://researchmap.jp/joub9b3my-1797580/#_1797580
に記載したサイトのお世話になっています。

作業方針(sequence)

Clang++では-std=c++03, C++2bの2種類
g++では-std=c++03, c++2bの2種類
でコンパイルし、

1)コンパイルエラーを収集する。
2)コンパイルエラーをなくす方法を検討する。
コンパイルエラーになる例を示すだけが目的のコードは、コンパイルエラーをなくすのではなく、コンパイルエラーの種類を収集するだけにする。
文法を示すのが目的のコード場合に、コンパイルエラーをなくすのに手間がかかる場合は、順次作業します。
3)リンクエラーをなくす方法を検討する。
文法を示すのが目的のコード場合に、リンクエラーをなくすのに手間がかかる場合は、順次作業します。
4)意味のある出力を作る。
コンパイル、リンクが通っても、意味のある出力を示そうとすると、コンパイル・リンクエラーが出て収拾できそうにない場合がある。順次作業します。

1)だけのものから4)まで進んだものと色々ある状態です。一歩でも前に進むご助言をお待ちしています。「検討事項」の欄に現状を記録するようにしています。

// 31.4.2 Overview [iostream.objects.overview]
//  In this Clause, the type name FILE refers to the type FILE declared in <cstdio> (31.13.1).
//  The header <iostream> declares objects that associate objects with the standard C streams provided for by the functions declared in <cstdio>, and includes all the headers necessary to use these objects.
// 273) It is the implementation’s responsibility to implement headers so that including <iosfwd> and other headers does not violate the rules about multiple occurrences of default arguments. The object cin controls input from a stream buffer associated with the object stdin, declared in <cstdio> (31.13.1).
// After the object cin is initialized, cin.tie() returns &cout. Its state is otherwise the same as required for basic_ios<char>::init (31.5.4.2).
//  The objects are constructed and the associations are established at some time prior to or during the first time an object of class ios_base::Init is constructed, and in any case before the body of main (6.9.3.1) begins execution. The objects are not destroyed during program execution.274
//  Recommended practice: If it is possible for them to do so, implementations should initialize the objects earlier than required.
//  The results of including <iostream> in a translation unit shall be as if <iostream> defined an instance of ios_base::Init with static storage duration.
//  Mixing operations on corresponding wide- and narrow-character streams follows the same semantics as mixing such operations on FILEs, as specified in the C standard library.
//  Concurrent access to a synchronized (31.5.2.5) standard iostream object’s formatted and unformatted input (31.7.4.2) and output (31.7.5.2) functions or a standard C stream by multiple threads does not result in a data race (6.9.2).
// [Note 1: Unsynchronized concurrent use of these objects and streams by multiple threads can result in interleaved characters. —end note]
// See also: ISO C 7.21.2
// 31.4.3 Narrow stream objects [narrow.stream.objects]
istream cin;
ostream cout;
//The object cout controls output to a stream buffer associated with the object stdout, declared in <cstdio> (31.13.1).
ostream cerr;
// The object cerr controls output to a stream buffer associated with the object stderr, declared in <cstdio> (31.13.1).
// After the object cerr is initialized, cerr.flags() & unitbuf is nonzero and cerr.tie() returns &cout. Its state is otherwise the same as required for basic_ios<char>::init (31.5.4.2).
ostream clog;
// The object clog controls output to a stream buffer associated with the object stderr, declared in <cstdio> (31.13.1).
// 31.4.4 Wide stream objects [wide.stream.objects]
wistream wcin;
// The object wcin controls input from a stream buffer associated with the object stdin, declared in <cstdio> (31.13.1).
// After the object wcin is initialized, wcin.tie() returns &wcout. Its state is otherwise the same as required for basic_ios<wchar_t>::init (31.5.4.2).
wostream wcout;
// The object wcout controls output to a stream buffer associated with the object stdout, declared in <cstdio> (31.13.1).
wostream wcerr;
// The object wcerr controls output to a stream buffer associated with the object stderr, declared in <cstdio> (31.13.1).
//  274) Constructors and destructors for objects with static storage duration can access these objects to read input from stdin or write output to stdout or stderr.
// After the object wcerr is initialized, wcerr.flags() & unitbuf is nonzero and wcerr.tie() returns &wcout. Its state is otherwise the same as required for basic_ios<wchar_t>::init (31.5.4.2).

検討事項(agenda)

コンパイルエラーを取るか、コンパイルエラーの理由を解説する。

応用例1 AUTOSAR C++

AUTOSARでC++のコーディング標準を作っている。 
MISRA-C++コーディング標準の改訂をまたずに、C++14に対応したかったためかもしれない。 

Autosar Guidelines C++14 example code compile list

MISRA C++, AUTOSAR C++について

応用例2 MISRA C/C++

MISRA C まとめ #include

MISRA C++ 5-0-16

応用例3 CERT C/C++

SEI CERT C++ Coding Standard AA. Bibliography 確認中。

MISRA C/C++, AUTOSAR C++, CERT C/C++とC/C++工業標準をコンパイルする

応用例4 箱庭 

箱庭もくもく会 #10 日時:2022/09/14(水) 17:30-19:30

箱庭ではUnityをはじめC++を使っているらしい。 

ここでコンパイルしたコードと同じようなコードを使っているか、
ここで出たコンパイルエラーと同じようなエラーがでたかを
いろいろな版のコンパイラでコンパイルして確認していく。

この項目は、箱庭プロジェクトを市場分析の対象として、原則的には、箱庭プロジェクトの外部から分析し、外部から箱庭の広告宣伝のための戦略会議を仮想した結果、仮想「箱庭もくもく会」を開催してみることを企画するものである。 
一切の内容は、箱庭プロジェクト、Athrill, TOPPERSとは無関係である。 
一(いち)参加データアナリストの、個人的なつぶやきです。

仮想戦略会議「箱庭」

お盆には「箱庭」記事を書きましょう「もくもく会」の題材になる(1)

エンジニア夏休み企画

個人開発と読書感想文に焦点を当てたのは良い企画だと思った。

個人開発

【個人開発】 効率的な背景 <エンジニア夏休み企画>

Cコンパイラの試験を一人でもくもくとやっているのは個人開発の一つの姿です。

読書感想文

CコンパイラによるC言語規格の読書感想文として掲載しています。
コンパイル実験が、C++N4910に対する、G++とClang++による感想文だということご理解いただけると幸いです。

読書感想文は人間かAIだけが作るものとは限りません。
本(電子書籍を含む)を入力として、その内容に対する文字列を読書感想文として受け止めましょう。
元の文章をあり方、コンパイルできるように電子化しておくこと、コンパイラが解釈可能な断片の作り方など。

自己参考資料(self reference)

関連する自己参照以外は、こちらの先頭に移転。

C言語(C++)に対する誤解、曲解、無理解、爽快。
