Not passing FMU Check

[sunne]

Hi all,
The FMU checker provided in http://fmi-standard.org/ shows some issues when checking the fmu created with pythonfmu build.

InitialUnknowns? PythonFMU does not currently populate those. You might add them manually the information to your XML, but the importing tool may potentially discard this information anyway.

Note: The FMU should still be functional even though FMU Checker complains.

Yep, that's it. I have problems when importing the fmu into Adams Controls and I thought that was the problem. I fixed that, FMU Check says it's ok but Adams still does not like the created fmu. It's not a dependency problem, since I tried with a bare example, no module imports, only one input and one output, and the doStep() is empty (just pass).
I tried opening it with FMPy and it works.
It's probably another issue, or an issue for Adams but, has anyone opened a pythonfmu's fmu with Adams?
Thanks!

If Adams internally loads Python, it will likely fail.

[sunne]

Yes, it does. It has an internal installation which may be accessed, thus additional packages may be installed. I installed pythonfmu there but still fails to load the fmu. Any additional thoughts on it?
Many thanks!

So if Adams loads Python.dll (or .so on unix), and that dll is incompatible with the .dll expected by PythonFMU it just won't work.
If Adams loads Python 3.5 <= then it will fail no matter what. If the issue is bitness (e.g. Adams loads 32-bit Python), you could try compiling PythonFMU for 32-bit manually and use that.

According to the devs, it's Python 3.6.4 what's in the box. How can I compile PythonFMU for 32-bit manually? Many thanks!

(at this point, I think this could be more a Discussion than an Issue, idk if it's ok to keep it here...)

If Adams does use 32-bit Python, you could try to run https://github.com/NTNU-IHB/PythonFMU/blob/master/pythonfmu/pythonfmu-export/build_win.sh with -A Win32

Your Python installation then needs to be 32-bit as well.

That might work.

No need to check, it's 64-bit:
'3.6.4 (default, Feb 22 2018, 09:47:04) [MSC v.1912 64 bit (AMD64)]'
I've run out of ideas :)
