Description Иванников Александр (SAF0001) 2025-07-06 16:13:45 MSK 
Чистая установка, при попытке компиляции clang-ом простейшей программы c++ (например так: clang++ main.cpp -o App0001), включающей в себя заголовок стандартной библиотеки iostream, появляется ошибка:

fatal error: 'iostream' file not found.

Установка пакета "gcc13-c++-13.2.1-alt3.x86_64" и его зависимостей решила данную проблему, но как то странно - компилятор установлен, а стандартная библиотека нет, хорошо бы исправить.

Забыл добавить - перед попыткой компиляции из командной строки, был установлен QT Creator flatpak

- clang: added requirement of gcc-c++ (closes #55062).

  После этого изменения перестал собираться chromium:

* Thu Jul 10 2025 L.A. Kostis <lakostis@altlinux.ru> 20.1.7-alt0.3
- clang: remove gcc-c++ from requires (as it breaks libcxx
  aware apps like chromium).

  Спасибо!
