Hi,

As per Readme file libwebsocket requires openssl installes.

openssl is here :---
*openssl: /usr/bin/openssl /usr/bin/X11/openssl /usr/share/man/man1/openssl.
1ssl.gz*

But i am not able to find the -- open ssl header folder in ---
/usr/lib
/usr/local/lib

This means that openssl is not installed ? Then how come openssl executable
is there in -- /usr/bin ?

Please suggest what shall i do. Install openssh again

//Din
