stackless python 2.7.9 and openssl-1.1.1g
Hi,
I am using stackless Python 2.7.9 in my project and openssl-1.0.2q.
I just upgraded the Openssl version to 1.1.1g, due to which python
compilation started failing. So, I patched _hashopenssl.c and _ssl.c file
in Python Modules as per new openssl to make compilation successful.
But when I run my image on target HW, I am getting below errors. It
looks like Openssl 1.1.1g libraries are not linked to Python.
I am struggling with this issue since many days. Looks like something I
missed in my patching. Could someone please help on this.

Re: stackless python 2.7.9 and openssl-1.1.1g
Hi Barry, Thanks for your response. I am not an expert in python code. Could you please elaborate a bit more on this. Which cpython code are you referring to? did you modify other files also apart from _hashopenssl.c and _ssl.c to work with openssl-1.1.1g ?

Thanks Barry. Some warnings were left in code after patching cpython files. After fixing them, all those errors are gone. Now I have another issue. now the threading module in python is not found. I don't see this is anyway related to openssl upgrade but this issue is not occurred where openssl has not been upgraded. File "/usr/lib/python2.7/site-packages/websocket/__init__.py", line 22, in from ._abnf import * File "/usr/lib/python2.7/site-packages/websocket/_abnf.py", line 30, in from threading import Lock File "threading.py", line 6, in import thread ImportError: No module named thread Could you give any clue on this ?
