If you are developing some native C application based on openssl API’s ( https://www.openssl.org/docs/ ) , you will need to include necessary header at the top of the C program as,
Error received while compilation of our C program,
fatal error: openssl/ssl.h: No such file or directory
Now, if you use such header and tried to compile on ubuntu, you may see an error like “fatal error: openssl/ssl.h: No such file or directory” . In such case, use below command as solution to install missing development headers dependency for ubuntu.
$ sudo apt-get install libssl-dev
