Valgrind / R не работает: «Неустранимая ошибка: невозможно создать R_TempDir»

Question

Прежде всего, я не очень разбираюсь в подобных вещах, поэтому я могу написать глупый вопрос, пожалуйста, будьте добры; -)

У меня есть R-код, который вызывает код C ++. К сожалению, есть проблема с моим кодом, возможно, память не отображена, и я хотел бы использовать valgrind, чтобы попытаться понять, где ошибка.

Я уже использовал его пару лет назад, но теперь, похоже, он не работает. Когда я обедаю следующую команду

R -d valgrind

Я получаю этот вывод

и R тогда не загружается. Я не знаю, как это решить. Я знаю, что ошибка «Неустранимая ошибка: невозможно создать R_TempDir» может означать, что на жестком диске больше нет места, но это не так.

Я на MacBook Pro, с High Sierra и R 3.5.0

Answer 1

Valgrind выдает сообщение об ошибке, сообщающее, что системный вызов unix: 475 не обрабатывается.

В таком случае он сообщает гостевому приложению, что системный вызов не выполнен, с ошибкой ENOSYS.

Системный вызов 475 для Дарвина - системный вызов Макдирата. Я предполагаю, что когда этот системный вызов потерпит неудачу, Затем R сообщает о фатальной ошибке, что не может создать R_Tempdir.

Как указано в сообщении об ошибке, вы должны отправить сообщение об ошибке в valgrind bugzilla.

Вы также можете попытаться исправить это: это может быть тривиальное изменение в файле valgrind m_syswrap / priv_syswrap-darwin.h, чтобы сделать что-то похожее, например, на линия прочитайте ссылку на несколько строк выше.
