I am trying to get Microsoft's Quantum Development Kit to work on a CentOS 7 machine. I followed the instructions for installing dotnet, and the trivial dotnet 'Hello World' works. I also installed Visual Studio from yum and installed the Microsoft Quantum Development Kit for Visual Studio from the Visual Studio explorer.
After cloning their github repo. I try:
dotnet_vm: Teleportation$ cd ~/Quantum/Samples/Teleportation/
dotnet_vm: Teleportation$ scl enable rh-dotnet21 bash
dotnet_vm: Teleportation$ dotnet run

This looks like the same error. I tried what I thought was the linux equivalent solution :
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/
I still get the same Error. Also, I do not have the AVX instruction set enabled on my computer (which might be a potential issue?).
E.g.
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$
I do not have any Windows experience and these do not look like typical Linux libraries (not .so or .a).
QUESTION: How do I get this to work?
Following El capi's answer, I looked at the libraries linked to : e.g.
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

/lib64/ld-linux-x86-64.so.2 (0x00007f1fb656a000)
To resolve this versioning issue with regards to GLIBCXX_3.4.21, I installed gcc-5.1.0 (and its dependencies). Then running the code:
dotnet_vm: Teleportation$ dotnet run
