Just to add also. when i disabled the ssl in Apache, mod_wsgi was working fine then. As mentioned above i installed open ssl from source , referred this url - *https://stackoverflow.com/questions/53543477/building-python-3-7-1-ssl-module-failed*
But still getting error mentioned in above mail. If you can suggest some doc how we can compile openssl with proper instructions.
