C++17 - The Complete Guide clang++とg++でコンパイルしてみた(まとめ)
https://qiita.com/kaizen_nagoya/items/c000f307e642990781e1

目的(purpose)

C++17 - the complete guide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の第一歩です。

成果(outcome)

(1)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。
(2)同じエラーであってもMessageの表現が違う。
(3) Error Messageのネットで検索する際に役立つ。

検討事項(agenda)

1)コンパイルエラーをなくす修正方法
1.1 inlinethreadlocal1, inlinethreadlocal2
２つのファイルをコンパイル対象に

$ clang++ ./lang/inlinethreadlocal1.cpp ./lang/inlinethreadlocal2.cpp -std=c++2a -Wall
$ ./a.out
main() begin:
- gName: global
- tName: tls
- lName: local
main() later:
- gName: thread1 name
- tName: thread1 name
- lName: thread1 name
foo() begin:
- gName: thread1 name
- tName: tls
- lName: local
foo() end:
- gName: thread2 name
- tName: thread2 name
- lName: thread2 name
main() end:
- gName: thread2 name
- tName: thread1 name
- lName: thread1 name
$ g++ ./lang/inlinethreadlocal1.cpp ./lang/inlinethreadlocal2.cpp -std=c++2a -Wall
$ ./a.out
main() begin:
- gName: global
- tName: tls
- lName: local
main() later:
- gName: thread1 name
- tName: thread1 name
- lName: thread1 name
foo() begin:
- gName: thread1 name
- tName: tls
- lName: local
foo() end:
- gName: thread2 name
- tName: thread2 name
- lName: thread2 name
main() end:
- gName: thread2 name
- tName: thread1 name
- lName: thread1 name

2)役に立つまたは意味のあるその他の出力

台本(script)

毎回コンパイル条件を変えてコンパイルするのに、一気にコンパイルする方法

cga.sh

#!/bin/bash
while read line
do
  echo "clang++ $line -std=c++2a -Wall"
  clang++ $line -std=c++2a -Wall 
  if [  -e a.out ]; then
  ./a.out
  rm a.out
  fi
  echo "g++ $line -std=c++2a -Wall"
  g++ $line -std=c++2a -Wall 
  if [  -e a.out ]; then
  ./a.out
  rm a.out
  fi
done < ./$1

do.sh

#!/bin/bash
while read line
do
 ls ./$line/*.cpp > ./$line/$line
 ./cga.sh ./$line/$line > $line.log.txt &> $line.log.txt
