CUDA 2.1「錯誤：未知類型名稱‘爲size_t’」

Question

操作系統：Ubuntu 11.10 x86_64的 CUDA：V 2.1

當試圖使像matrixMul一個示例程序，我得到了廣泛的誤差的大小，其中大部分是「未知類型名稱'size_t'。」我已經確保將/ usr/local/cuda/bin放在我的PATH以及/etc/ld.so.conf.d中的.conf中的/ usr/local/cuda/lib中。

任何想法，爲什麼我得到這些錯誤？

謝謝！

Answer 1

升級CUDA！

CUDA 2.1在2008/9發佈，您應該升級（例如到CUDA 4.2）。官方Ubuntu 11.10尚未支持，我沒有嘗試過，主要的問題可能是你將不得不安裝GCC 4.5.2。有關受支持版本的更多信息，請參見Release Notes。

Answer 2

確保您#include <stddef.h>

如果這是一個C++程序，嘗試添加行using namespace std。

該問題與「bin」或$ PATH無關;它與你在編譯時選擇哪個系統頭文件和系統定義有關。
