<div dir="ltr"><div><div><div>Hi,<br><br></div>Does your supercomputer have X installed on the compute nodes? If it does you may just need to set the environment to do that ("export DISPLAY=:0" for many machines). It looks like you do since I don't think you'd be able to build Catalyst without those libraries. <br><br>If you don't have a graphics card or can't use it then you'll need to build with OSMesa and build Catalyst against that. Information on that is at <a href="http://www.paraview.org/Wiki/ParaView/ParaView_And_Mesa_3D">http://www.paraview.org/Wiki/ParaView/ParaView_And_Mesa_3D</a>.<br><br></div>Cheers,<br></div>Andy<br><div><div><br></div></div></div><div class="gmail_extra"><br><div class="gmail_quote">On Tue, Nov 24, 2015 at 7:13 AM, Dan Zhao <span dir="ltr"><<a href="mailto:danzhao.nudt@gmail.com" target="_blank">danzhao.nudt@gmail.com</a>></span> wrote:<br><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"><div dir="ltr"><div style="font-size:14px">Hi, everyone. </div><div style="font-size:14px">Recently I am trying to run catalyst on supercomputer.
