How to compile .c file with OpenSSL includes?

Question

I am trying to compile a small .c file that has the following includes:

#include 
#include 
#include 

        

Answer 1

Your include paths indicate that you should be compiling against the system's OpenSSL installation. You shouldn't have the .h files in your package directory - it should be picking them up from /usr/include/openssl.

The plain OpenSSL package (libssl) doesn't include the .h files - you need to install the development package as well. This is named libssl-dev on Debian, Ubuntu and similar distributions, and libssl-devel on CentOS, Fedora, Red Hat and similar.
