无法加载DLL 'Microsoft.Quantum.Simulator.Runtime.dll‘(CentOS 7)

Question

我正试图让微软量子开发工具包在CentOS 7机器上工作。我遵循了安装使用说明的dotnet，以及简单的dotnet 'Hello‘工作原理。我还从yum安装了Visual，并从Visual安装了Visual的。

在克隆他们的github回购后。我试着：

dotnet_vm: Teleportation$ cd ~/Quantum/Samples/Teleportation/
dotnet_vm: Teleportation$ scl enable rh-dotnet21 bash
dotnet_vm: Teleportation$ dotnet run
/home/user/Quantum/Microsoft.Quantum.Canon/Microsoft.Quantum.Canon.csproj : warning NU1603: Microsoft.Quantum.Canon depends on NETStandard.Library (>= 2.0.2-servicing-25519-03) but NETStandard.Library 2.0.2-servicing-25519-03 was not found. An approximate best match of NETStandard.Library 2.0.2 was resolved. [/home/user/Quantum/Samples/Teleportation/TeleportationSample.csproj]

An approximate best match of NETStandard.Library 2.0.2 was resolved.

Unhandled Exception: System.DllNotFoundException: Unable to load shared library 'Microsoft.Quantum.Simulator.Runtime.dll' or one of its dependencies. In order to help diagnose loading problems, consider setting the LD_DEBUG environment variable: libMicrosoft.Quantum.Simulator.Runtime.dll: cannot open shared object file: No such file or directory

   at Microsoft.Quantum.Examples.Teleportation.Program.Main(String[] args) in /home/user/Quantum/Samples/Teleportation/Program.cs:line 13

这看起来也是同样的错误。我尝试了我认为与linux等价的解决方案：

cp ~/.nuget/packages/microsoft.quantum.development.kit/0.2.1809.701-preview/runtimes/linux-x64/native/Microsoft.Quantum.Simulator.Runtime.dll ~/.nuget/packages/microsoft.quantum.development.kit/0.2.1809.701-preview/lib/netstandard2.0/

我还是会犯同样的错误。此外，我的计算机上没有启用AVX指令集(这可能是一个潜在的问题？)。

例如。

 grep flags /proc/cpuinfo 
flags       : fpu de pse tsc msr pae mce cx8 apic sep mtrr pge mca cmov pse36 clflush mmx fxsr sse sse2 syscall nx lm nopl pni cx16 hypervisor lahf_lm abm
flags       : fpu de pse tsc msr pae mce cx8 apic sep mtrr pge mca cmov pse36 clflush mmx fxsr sse sse2 syscall nx lm nopl pni cx16 hypervisor lahf_lm abm
dotnet_vm: Teleportation$ 

我没有任何Windows经验，这些看起来不像典型的Linux库(不是.so或.a)。

问:我怎样才能让它发挥作用？

在El capi的回答之后，我查看了与以下链接的图书馆：

dotnet_vm: gcc-5.1.0$ ldd /home/user/.nuget/packages/microsoft.quantum.development.kit/0.2.1809.701-preview/lib/netstandard2.0/Microsoft.Quantum.Simulator.Runtime.dll

为了解决与GLIBCXX_3.4.21有关的版本控制问题，我安装了gcc-5.1.0 (及其依赖项)。然后运行代码：

dotnet_vm: Teleportation$ dotnet run

啊，真灵!

Microsoft.Quantum.Simulator.Runtime.dll是一个普通的Linux库(.so)，它只是重新命名以便更容易地支持跨平台。

与你连在一起的问题类似，但是您应该查看Ubuntu的答案:使用ldd找出依赖项，并安装缺少的任何内容。正如在那篇文章中一样，问题很可能是您缺少libgomp，但我不熟悉CentOS。

不启用AVX将使事情变得更慢，特别是在处理大量的量子位时，但是您仍然可以运行。
