[Python-Dev] Re: compiled python3.10 is unable to find _ssl
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 mailing list -- python-dev@python.org To unsubscribe send an email to python-dev-le...@python.org https://mail.python.org/mailman3/lists/python-dev.python.org/ Message archived at https://mail.python.org/archives/list/python-dev@python.org/message/HQUMR3RSUWXC5FVQTTVCOW6GV7DLY3UK/ Code of Conduct: http://python.org/psf/codeofconduct/
[Python-Dev] Re: compiled python3.10 is unable to find _ssl
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

Your configure script did pick up openssl as the support version was not found. What is your operating system? Make sure you have supported version of ssl. Python requires openssl 1.1.1 or higher. On Mac, I had to use brew to install it and --with-openssl flag. On some linux machines, I have had to download openssl, compile it, and point my the configure script to (location I compiled openssl).
