fatal error: openssl/opensslv.h: No such file or directorySolution :
On Ubuntu, this file is normally present at “/usr/include/openssl/opensslv.h”
If this file is not present, we have to install the OpneSSL development package which can install this headers on Ubuntu.
$ sudo apt-get install libssl-dev
