[mcstas-users] McStas 3.0 and NCrystal (WSL)

[Peter Kjær Willendrup]

Dear Michał,

Thank you for reporting this issue - which is indeed separate from the mcgui issue from yesterday.

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.


To solve it, please

1) Install the ncrystal libraries:
sudo apt-get install mcstas-ncrystal-3.0

2) Reinstall the core mcstas-3.0 package:
sudo apt-get install --reinstall mcstas-3.0


After these steps, I was able to compile the instrument, see attachment.

Best,
Peter

Dear McStas users,

Thank you for the help with previous issue, i.e. starting mcgui on Ubuntu 20.04, the solution made mcgui work. However, I encountered another problem, this time with NCrystal - I do not know, whether that is a different part of the same issue, or is it something entirely different. As I understand from the changes in Mcstas 3.0:
"Updated version 2.2.2 NCrystal library from T. Kittelmann (ESS) and X.X. Cai (CSNS), distributed with McStas on Unix
platforms only. With McStas 3.0, NCrystal is more tightly integrated and should run without using ncrystal_preparemcstasdir."
However, I cannot get the NCrystal sample to work, using McStas on Windows 10 (WSL1 Ubuntu 20.04):
"
./PANDA_Michal_DV_draft.c: At top level:
./PANDA_Michal_DV_draft.c:7890:10: fatal error: NCrystal/ncrystal.h: No such file or directory
7890 | #include "NCrystal/ncrystal.h"
      |          ^~~~~~~~~~~~~~~~~~~~~
"

Please find attached the log (together with running mcgui) as well as the .instr and .c files. I would be grateful for any help with it.

Kindly,
Michał Dembski-Villalta
