компиляция libc ++ с помощью clang ++ в Ubuntu

1 голос
/ 25 июня 2011

Моя ОС - Ubuntu-11.04. Я успешно скомпилировал llvm с помощью clang.Затем я попытался скомпилировать libcxx с помощью clang ++, я внес изменения в $ LIBCXX_DIR / lib / buildit.sh, прочитав следующий

http://lists.cs.uiuc.edu/pipermail/cfe-dev/2011-February/013228.html

Измененный файл $ LIBCXX_DIR / lib / builditвставляется после сообщения об ошибке.

с измененным buildit.sh я получаю следующие ошибки.Кажется, clang ++ не может успешно скомпилировать заголовочный файл 'string'.Вот полный отчет о компиляции:

Ну, сообщение об ошибке само по себе объясняется, см. Ответ Говарда Хиннанта на мой вопрос: std :: async в clang 3.0 + libc ++ не работает? Я думаю, это то же самое место.
