CUDA 2.1「のエラー：不明なタイプ名 『size_t型』」

Question

システム：Ubuntuの11.10 x86_64版 CUDA：V 2.1

にしようとしているほとんどが、私はエラーの大規模な量を得るmatrixMulのようなプログラム例、 "不明な型名 'size_t'。"私は/ usr/local/cuda/binを/etc/ld.so.conf.dの.confの/ usr/local/cuda/libと同じようにPATHに置いています。

なぜこれらのエラーが発生しているのですか？

Answer 1

アップグレードCUDA！

2008/9にCUDA 2.1がリリースされたため、アップグレードする必要があります（たとえば、CUDA 4.2）。公式にはUbuntu 11.10はまだサポートされていません。自分で試したことはありませんが、主な問題はGCC 4.5.2をインストールする必要があることです。サポートされているバージョンの詳細については、Release Notesを参照してください。

Answer 2

これはC++プログラムがある場合は、#include <stddef.h>

、ラインusing namespace stdを追加してみていることを確認します。

この問題は "bin"や$ PATHとは関係ありません。コンパイル時にどのシステムヘッダとシステム定義を取得するのかをすべて把握しています。
