Linux issues

Ubuntu 20.04 Python 3.8

from delphifmx import *

Causes:
Process finished with exit code 139 (interrupted by signal 11: SIGSEGV)

Python app created with Delphi runs properly so dependencies should be installed.

Is it like the error when you run a Python program? Or whether you ran this line on the REPL and came across this?

[tomekkosinski]

Just calling "from delphifmx import *" frim the python command prompt!

I couldn't reproduce the same issue with Python 3.9. Will check a 3.8 env and get back to you..

[Priyatham10]

Still couldn't reproduce the issue using Python 3.8. Hey @cosina , could you please give some more details? screenshots, more system info and all..

Hi,

1. Use Hyper-V (Win11)
2. "Quick Create" Ubuntu 20.04 LTS
3. Python 3.8 is already there
4. sudo apt install python3.8-venv
5. Install Linux dependencies according to (https://docwiki.embarcadero.com/RADStudio/Sydney/en/FireMonkey_for_Linux)
6. PIP delphifmx
7. open Python prompt and execute "from delphifmx import *"
8. SIGSEG errors is raised

I tested the same scenario on 22.04 and built-in pyton3.10 and everything works as expected.

In general, the SIGSEGV is a segmentation fault error that is related to memory mapping. I think this is not related to the Ubuntu or Python version. Something broke in any of the installation processes, which might've raised this issue. The second time you might have successfully installed everything without breaking anything unknowingly which made the import work sccessfully.

I think we can close the issue if you're not facing the issue anymore..

On my side problem is persistent on any version other then Ubuntu 22
After some trace messages i found that .pyd crashes as soon as it reach
timeModule := PyImport_ImportModule('time'); line.

Oh then, it's a matter of concern. We shall try to emulate the issue and look for the reason and shall try a fix for it..

Python distributed by APT is not compatible with DelphiFMX. Python must provide interpreter's symbols somehow.

There are some discussions across this issue:
#20
#22

Let me know if it applies to you.
