Compilation error

[Wenyuan]

Dear community:

I’m trying to use Openlb in WSL on Win10 computers. When “make” was used, a compilation error occurred:

cavity2d.d:1: *** multiple target patterns. Stop.

The versions of gcc and GUN make are as follows:

gcc (Ubuntu 9.4.0-1ubuntu1~20.04.1) 9.4.0

How to solve this problems please?

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?

Thanks for your reply!

After the reinstallation of wsl and dependency, the version 1.6 works well now. It seems that there was something wrong with the environment, which can be settled through reinstallation and reboot.
