CUDA 2.1 «ошибка: неизвестное имя типа„size_t“»

Question

система: Ubuntu 11.10 x86_64 CUDA: v 2.1

При попытке сделать пример программы, как matrixMul я получаю обширное количество ошибок, большинство из которых являются msgstr "неизвестное имя типа 'size_t'." Я обязательно поставил/usr/local/cuda/bin в свой PATH, а также/usr/local/cuda/lib в .conf в файле /etc/ld.so.conf.d.

Любые идеи, почему я получаю эти ошибки?

Answer 1

Обновление CUDA!

CUDA 2.1 был выпущен в 2008/9 году, вы должны обновить (например, до CUDA 4.2). Официально Ubuntu 11.10 еще не поддерживается, я сам не пробовал, основная проблема, вероятно, в том, что вам нужно будет установить GCC 4.5.2. Дополнительную информацию о поддерживаемых версиях см. В разделе Release Notes.

Answer 2

Убедитесь, что вы #include <stddef.h>

Если это программа С ++, попробуйте добавить строку using namespace std.

Проблема не имеет ничего общего с «bin» или вашим $ PATH; он имеет все, что связано с заголовками систем и определениями системы, которые вы собираете во время компиляции.
