<div>Hello Midas World,</div>
<div><br>
</div>
<div>I'm trying to build an instance of Midas with ParaviewWeb enabled. I'm working on an Ubuntu 12.04 instance. Midas built fine, but I'm having a difficult time getting Paraview to build. Just curious if the paraview-python package that is available in the
ubuntu distribution is sufficient for this purpose? If it is, curious about the details of the configuration for the instructions: "Make sure to symlink the www directory of your ParView build directory…"</div>
</div>
<div><br>
</div>
<div>I'm suspicious of the package since when I try to run pvpython I get an error:</div>
<div><br>
</div>
<div>"Error converting executable file "/usr/bin/../lib/paraview/pvpython" to real path: no such file or directory"</div>
