SSL Header file issue #include <openssl/ssl.h>

[di...@devtechm2m.com]

Hi All,

I am using Pocket beaglebone, Debian 9.2, Ethernet W5500-SPI1, Cross compiler "arm-cortexa8-linux-gnueabihf-gcc"

I want SSL TCP communication with server IP (49.248.XX.XX).

I am able to communicate with server without SSL.

But, for SSL I am adding header file 

#include <openssl/ssl.h>

#include <openssl/err.h>

and after adding this header file when I compile code it is showing error 

"fatal error: openssl/ssl.h: No such file or directory"

I don't know what is happening and how to resolve this.

Thanks.....
