<p>Hi Mathieu,</p>
<p>for info, here is the backtrace for the PV5.2 bug with seg fault
when disconnecting (sorry it was stuck in my draft e-mails since a
while :-). <br>
</p>
<p>I did not find the time to rebuild with the last version. I will
try to do so soon... I think I have to rebuild it from source as
the basic goal is to package it on nix system (which uses internal
nix package dependencies). I currently use 5.3 RC2 for my
developments and it works completely fine on any system (not
including nix :-).<br>
</p>
<p>Bye,</p>
<p>Yves<br>
</p>

<div>Hi Yves<br>
<br>
</div>
In order to test with the last version, you do not need to
compile, you can download a nightly build on the ParaView
download page.<br>
</div>
(Highest number means newer).<br>
</div>
<div>Let me know how it goes.<br>
</div>
<div><br>
</div>
I will defer to others regarding the packaging question.<br>

<p>Hi Mathieu :-)</p>
<p>yes it's for the case of multi-server (actually single
client) option. I will get the source from the git
repository master a give it another try.</p>
<p>OK for the debug, I can compile it again in debug but
it takes a long time on my little test laptop so I was
wondering maybe some other tricky test on the release
version ;-) I will let the debug build run this week-end
and send a quick report.</p>
<p>By the way, do you plan to support nix packages build
in the future for Paraview ? The problem I will
encounter now is that Paraview depends on video card
driver OpenGL libs so that to get good performances, I
will break the nix packages philosophy of being
independent from the operating system specific kernel...<br>
</p>
<p>Thanks for the answer!</p>
<p>Yves<br>

<div>Hi Yves !<br>
<br>
</div>
Do you happen to use the
multi-clients/multi-server option ? we
recently corrected a bug that sound like
yours, will be fixed in ParaView 5.3.<br>
</div>
In any case, you may want to try with the last
version of paraview master.<br>
<br>
</div>
In order to debug, the first step would be to
build ParaView in Debug, and then run it with a
debuger, in order to get a backtrace of the
segfault.<br>
<br>
</div>
Best Regards,<br>

<p>Dear Paraview team,</p>
<p>we are currently studying the opportunity
of migrating our computing grid
environment from "module" system to "nix"
packaging system (<a
moz-do-not-send="true"
class="m_8580887374267790081m_3538402776635204479moz-txt-link-freetext"
href="https://nixos.org/"
target="_blank">https://nixos.org/</a>).
In that purpose, I'm trying to compile and
pack Paraview 5.2.0 with its dependencies
with nix packages (<a
moz-do-not-send="true"
class="m_8580887374267790081m_3538402776635204479moz-txt-link-freetext"
href="https://nixos.org/nixos/packages.html" target="_blank">https://nixos.org/nixos/packa<wbr>ges.html</a>).
<br>
</p>
<p>To do so, I first installed nixos on a
local laptop and give it a try. The main
issue I encountered was to update my nixos
kernel with native videocard drivers but
OK, that's done. Then using the attached
nix package script (a slight evolution on
paraview 4.0.1 existing one), I could have
packetized 5.2.0 succesfully and it runs
very well.</p>
<p>However, I still get an error when I'm
trying to use MPI functionality. The MPI
itself with parallelism works, as I can
run a auto-MPI session without problem.
The issue occurs when <b>servermanager.Disconnect()
function is called => Seg fault</b>
with no more info... The bad thing is that
the Disconnect function is called every
time I would like to connect to a server
(to disconnect the built-in one). This is
also the case when passing the pvserver in
command-line argument.</p>
<p>Do you have an idea of the cause of this
seg fault ? Maybe could you help me find
any useful test to debug this ?</p>
<p>Thanks in advance for your support,</p>
<p>Best regards,</p>
