nagioscoreI was installing Nagios Core Server. I facing following error while i compiling nagios-plugin-1.4.16. I execute make command, following error show on the screen

 check_http.c:312:9: error: ‘ssl_version’ undeclared (first use in this function)
make[2]: *** [check_http.o] Error 1
make[2]: Leaving directory `/home/nicadmin/nagios-plugins-1.4.16/plugins'
make[1]: *** [all-recursive] Error 1
make[1]: Leaving directory `/home/nicadmin/nagios-plugins-1.4.16'
make: *** [all] Error 2

From the error above , it look like missing some SSL component. I trying to do cross check existing nagios server, i notice that openssl-devel package is require to install.
So i try to enter following command to install openssl-devel package

 yum install openssl-devel

After install the openssl-devel package, i try to complile nagios-plugin again and i successfully compile it. ;-)
