Running DWSIM automation2() on manjaro

[Mihály Bence]

Dear Daniel!

I want to use the automation2() interface on a manjaro system, but when I create the automation2() instance I get the following error:
"Assertion at assembly.c:1939, condition `is_ok (hook_error)' not met, function:mono_assembly_invoke_load_hook_internal, (null) assembly:/usr/lib/mono/4.5/mscorlib.dll type:ReflectionTypeLoadException member:(null)**"

I use pythonnet as well.

What could be the problem?

Thanks in advance,
Bence

Can you try running this code to see if it works? https://github.com/DanWBR/DWSIM.Automation.Test.macOS/blob/master/DWSIM.Automation.Test.macOS/Program.cs

Dear Daniel,

I get the same error when trying to use Automation2() in a Python script using the pythonnet package. I'm running the script from an IDE (PyCharm, VSCode, tried on both) on macOS:

* Assertion at assembly.c:1939, condition is_ok (hook_error)' not met, function:mono_assembly_invoke_load_hook_internal, (null) assembly:/Users/alfonsovillegas/opt/anaconda3/envs/DWsimPython38/lib/mono/4.5/mscorlib.dll type:ReflectionTypeLoadException member:(null)

I managed to run my script using IronPython from the terminal but I would really prefer using the simple pythonnet package.

(I tried running your code "Program.cs" that you linked in your last message but I don't know if it is supposed to work on macOS (it didn't work)).

Thanks a lot for your help.
Alfonso
