Hi everyone, this is the first time I am writing here and I hope not to make too many mistakes.

I am trying to install SU2 on Ubuntu 21.10 and after launching the build with the command:

$ ./ninja -C build install

the terminal gives me some warnings.

and this

Finally, once the compilation is finished, if I try to launch SU2 from the terminal I return this error

[pcg]

The first warnings are in external libraries that we don't control.
The last looks like you have some MPI configuration problem.

First of all thanks for the reply. Could the problem be related to the 21.10 version of ubuntu and cgns
?

I finally solved it. The problem was in installing the OpenMpi package through the APT repository. Until now it had always worked with SU2 and Ubuntu versions prior to 21.10, but now to make it work i had to install OpenMpi in a classic way.

Hello，Salvatori Marco. I am a beginner learning SU2，who is currently installing and compiling SU2. I encountered the same problem as you mentioned in your post, but I was lucky enough to find your post. Could you please tell me how to download Openmpi and if there are any related websites and tutorials available. Looking forward to your reply, thank you.
