Reply To: Compilation error
Which version of OpenLB do you use? If you updated to the recently released version 1.6: Did it work on the exact same system using 1.5?
I just reconfirmed with a colleague using WSL on Windows 10 that both 1.5 and 1.6 work without issues in this configuration so I suspect some specific issue with your environment. Can you walk us through the exact steps between unpacking the clean tarball and producing the error?
