Any ideas ?

amykyta3 commented 2 years ago

Did some experimenting and it looks like the last supported version is Python3.7. Something changed in cpython since then.

mocallins commented 2 years ago

Need anything from me, to dive deeper ?

amykyta3 commented 2 years ago

I was able to reproduce the issue on my end so I think I have what I need. I suspect it is something to do with the libpython linking changes in Py3.8 described here (3rd bullet point): https://docs.python.org/3.8/whatsnew/3.8.html#changes-in-the-c-api On top of that, I saw some deprecation warnings on py3.9 and newer that also ought to be addressed.

Might be a few weeks before I get around to fixing due to my availability.

Okay No problem, Thank you

sm-shaw commented 2 years ago

Have been looking at something similar and seeing the same error tclpython3.so.5.0: undefined symbol: Py_NoSiteFlag testing tclpython as well

Updating the Makefile adding --embed got it working for me.

LDFLAGS+= $(shell $(PYTHON_CONFIG) --ldflags --embed)

hammerdb>package require tclpython3
5.0
hammerdb>set interpreter [python3::interp new]
python0
hammerdb>$interpreter exec {print("Hello World")}
Hello World

Without --embed you get the following dependencies

ldd tclpython3.so.5.0 
    linux-vdso.so.1 (0x00007ffd07364000)

Yes this helped for me as well. At least with the simlpe test. But at least the library loaded

amykyta3 commented 2 years ago

Thanks @sm-shaw for finding the solution! Latest Makefile should work. I also cleaned up some segfaults that would show up on py3.9 and newer during deletion of the interpreter. All versions seem to be working now on my end: https://github.com/amykyta3/tclpython/actions

mocallins commented 2 years ago

Cloned the latest copy and performed steps. Getting a sehmentation fault upon trying to delete the created interpreter. Also minor typo in the README.md and on the web page, the last command below.

[ pidev ] home/pi % package require tclpython3 5.0 [ pidev ] home/pi % set interpreter [python3::interp new] python0 [ pidev ] home/pi % $interpreter exec {print("Hello World")} Hello World [ pidev ] home/pi % puts [$interpreter eval 3/2.0] 1.5 [ pidev ] home/pi % python::interp delete $interpreter invalid command name "python::interp" while evaluating python::interp delete $interpreter [ pidev ] home/pi % python3::interp delete $interpreter Segmentation fault

amykyta3 commented 2 years ago

Odd. works fine on all active versions of Python on Ubuntu 20.04 and 22.04

I dont have a raspbian setup handy to try this. Could you paste the output of:

import sysconfig
import pprint
pprint.pprint(sysconfig.get_config_vars())
mocallins commented 2 years ago

my goodness, so  much output i can't capture it all for copy / paste, lol

just at a python prompt ?or inside tclpython ?

Hi, I'm facing a similar issue while importing the Python 'math' package.

% set py [python3::interp new] % $py exec {import math} Traceback (most recent call last): File "", line 1, in ImportError: /opt/rh/rh-python38/root/usr/lib64/python3.8/lib-dynload/math.cpython-38-x86_64-linux-gnu.so: undefined symbol: PyFloat_Type

The 'import math' works in a standalone Python shell, but not in the Tcl shell with tclpython. Any ideas how to fix this?

There is a modified version of libtclpy here used by the HammerDB project - as shown below this works correctly. So you may be able to apply some of the changes to libtcly to tclpython for it also to import correctly.

That works, thank you!
