VISUAL STUDIO 2013：错误 LNK2019：无法解析的外部符号 - cuRAND - 随机数生成器

Question

我研究了几个小时，

MSDN Microsoft - Linker Tools Error LNK2019
How to solve the error LNK2019: unresolved external symbol - function?
What is an undefined reference/unresolved external symbol error and how do I fix it?
Error LNK2019: unresolved external symbol _wWinMain@16 referenced in function ___tmainCRTStartup
How to get rid of this error: "MSVCRTD.lib(crtexe.obj) : error LNK2019: unresolved external symbol _main referenced in function ___tmainCRTStartup"

但还没有找到解决以下错误的方法，

Error 1 error LNK2019: unresolved external symbol _curandCreateGenerator@8 referenced in function _GPU_RNG F:\New\Eks\Visual Studio 2013\PEOPLE PROJECTS\RNGTests\CURANDRNGLib\CURANDRNG.cu.obj CURANDRNGLib

我应该添加#include 吗？ (我的英语不太好)

Answer 1

您应该针对 curand.lib 进行链接 - 将其添加到链接器 -> 输入 -> 附加依赖项下的属性工作表中。

这是打开详细链接器输出的方式：

Answer 2

我猜你的代码可能是在 Win32 平台上开发的。只有基本的 CUDA API 支持，但 Win32 上没有 CURAND 库支持。您可以尝试切换到开发 64 位版本。（项目 -> 属性 -> 更改顶部的平台选项）
