Question

系统：Ubuntu 11.10 x86_64 CUDA：v 2.1

当尝试制作像matrixMul这样的示例程序时，我会收到大量错误，其中大部分是“未知类型名称'size_t'。”我确保将/ usr / local / cuda / bin放在我的PATH中，将/ usr / local / cuda / lib放在/etc/ld.so.conf.d中的.conf中。

为什么我会收到这些错误？

谢谢！

Answer 1

确保#include <stddef.h>

如果这是一个C ++程序，请尝试添加行using namespace std。

问题与“bin”或$ PATH无关;它与您在编译时获取的系统头和系统定义有关。

Answer 2

升级CUDA！

CUDA 2.1于2008/9发布，您应升级（例如CUDA 4.2）。官方的Ubuntu 11.10尚不支持，我自己没有尝试过，主要问题可能是你必须安装GCC 4.5.2。有关支持的版本的详细信息，请参阅Release Notes。
