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

If you encounter this error during compilation, this is because of the following: The program you are trying to build is using OpenSSL, but necessary development files (libraries and header files) required to link with OpenSSL are missing on your Linux platform.

To fix this problem, you have to install OpenSSL development package, which is available in standard repositories of all modern Linux distributions.

To install OpenSSL development package on Debian, Ubuntu or their derivatives:

$ sudo apt-get install libssl-dev 

To install OpenSSL development package on Fedora, CentOS or RHEL:

$ sudo yum install openssl-devel 

After installing the package, try recompiling the program
