Dear Michał,
<div class=""><br class="">
</div>
<div class="">Thank you for reporting this issue - which is indeed separate from the mcgui issue from yesterday.</div>
<div class=""><br class="">
</div>
<div class="">It turns out I must have left out the mcstas-ncrystal-3.0 package from the mcstas-suite-python-ng package… And hence the found issue is likely present on any Debian- or Ubuntu based system.</div>
<div class=""><br class="">
</div>
<div class=""><br class="">
</div>
<div class="">To solve it, please</div>
<div class=""><br class="">
</div>
<div class="">1) Install the ncrystal libraries:</div>
<div class=""><span class="Apple-tab-span" style="white-space:pre"></span>sudo apt-get install mcstas-ncrystal-3.0</div>
<div class=""><br class="">
</div>
<div class="">2) Reinstall the core mcstas-3.0 package:</div>
<div class=""><span class="Apple-tab-span" style="white-space:pre"></span>sudo apt-get install --reinstall mcstas-3.0</div>
<div class=""><br class="">
</div>
<div class=""><br class="">
</div>
<div class="">After these steps, I was able to compile the instrument, see attachment.</div>
<div class=""><br class="">
</div>
<div class="">Best,</div>
<div class="">Peter</div>
