CentOS Linux release 7.9.2009 (Core)
trying to build python 3.10.4

I followed the instructions at 
https://docs.python.org/3/using/unix.html?highlight=openssl#custom-openssl and 
cannot import ssl in the resulting build.

My log of what I did follows. Struggling with this for a couple of days, so any 
help would be appreciated.

It turns out the one problem was being caused by the manual change to Makefile 
I made at 2022-05-23 11:35.

My build goes through now by prefixing after 
LD_LIBRARY_PATH=${LD_LIBRARY_PATH}:/usr/local/custom-openssl/lib after sudo, as 
the root account was not getting this environment variable.

Having said that, while the dynamic load library now gets built correctly (it 
wasn't with the Makefile change), I still see the same symptom. Will continue 
to debug.

I now see 

$ ls  /usr/local/python-3.10.4/lib/python3.10/lib-dynload/*_ssl*
/usr/local/python-3.10.4/lib/python3.10/lib-dynload/_ssl.cpython-310-x86_64-linux-gnu.so

but still see 

$ python3.10
 Python 3.10.4 (main, May 15 2022, 12:44:05) [GCC 4.8.5 20150623 (Red Hat

Solved!

The astute reader will notice that while I built the latest version of 
python3.10 2022-05-24 11:38, the one I was testing was built May 15 2022, 
12:44:05.

This was left over from an earlier iteration, and not cleaned up with a 
subsequent make clean that was run after another ./configure with a different 
--prefix value.

[Python-Dev] Re: problem with Distributed File System Replication and Namespacing and different versions of Python 3

2022-10-20 Thread Lou King 
Not sure if this is relevant, but I know they updated the openssl version
in Python 3.10. I had the opposite problem trying to use Python 3.10 on
CentOS 7 which has the old openSSL. I had to back off to 3.9. maybe running
over the network invoked openSSL at some point and that's where the
disconnect occurs?

I would check which openSSL your host os uses.
