Unable to load DLL 'Microsoft.Quantum.Simulator.Runtime.dll'

Question

Getting Unable to load DLL \'Microsoft.Quantum.Simulator.Runtime.dll\' error while trying to validate my Q# environment by running the teleport sample program.

Answer 1

Under Ubuntu bionic, I had to install libgomp1 because Microsoft.Quantum.Simulator.Runtime.dll depends on libgomp.so.1.

sudo apt install libgomp1

The dependency can be seen here.

ldd -r ~/.nuget/packages/microsoft.quantum.development.kit/0.2.1802.2202-preview/runtimes/linux-x64/native/Microsoft.Quantum.Simulator.Runtime.dll

linux-vdso.so.1 (0x00007ffcbb4f4000)
libstdc++.so.6 => /usr/lib/x86_64-linux-gnu/libstdc++.so.6 (0x00007fd537237000)
libm.so.6 => /lib/x86_64-linux-gnu/libm.so.6 (0x00007fd536e99000)
