Avoid client-server version mismatch

Francesc_Costa · October 16, 2020, 5:16pm

Hello,

I have successfully built Paraview from source code in a Ubuntu machine. I have a Paraview Desktop native app with version:

Windows version: 5.8.1

When I try to connect the Windows Paraview Desktop with the remote ubuntu server I get an error mismatch.

I am planning to rebuild the ubuntu server so that I do not have this mismatch. What git tag version should I update my code to?

Thanks,

Francesc

Which error do you have exactly ?

In the client(windows):

And in the ubuntu server:

Are you building ParaView 5.8.1 on your ubuntu machine ?

@wascott: We really need to improve the error handling in this case.

I built 5.8.1-1432-g4dbd3922cd in Ubuntu

mwestphal · October 21, 2020, 4:53pm

You should build the exact same version.

Francesc_Costa · October 21, 2020, 5:22pm

Ok, both are 5.8.1. I understand you mean the fourth number in the version that in Windows in the about is not shown.

Even when I go to the download page, for Windows I only see 5.8.1 with and without MPI while in Ubuntu I see more versions 5.8.1.x versions.

So, what version of Ubuntu should I install that it matches Windows 5.8.1?

mwestphal · October 21, 2020, 5:25pm

just use the 5.8.1 release for both.
5.8.1-1432-g4dbd3922cd is not a release, it is a nightly.

Thanks Mathieu!

It is working now.
