Compiling nagios-plugins-1.4.16 throws an error

I was installing Nagios on a new Ubuntu Server following this guide, but using the latest versions (Nagios 3.4.1 and Nagios Plugins 1.4.15).

Running make on the Nagios Plugins threw me the following error:
 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

A workaround is installing the libssl-dev package and reconfiguring.
root@host1:~/nagios-plugins-1.4.16# apt-get install libssl-dev
root@host1:~/nagios-plugins-1.4.16# ./configure --with-nagios-user=nagios --with-nagios-group=nagios
root@host1:~/nagios-plugins-1.4.16# make
root@host1:~/nagios-plugins-1.4.16# make install



  1. Thank you so much. That error was driving me nuts!

  2. Works like a charm!

  3. Awesome sauce, you are beautiful!

  4. Thanks! in red hat the command was
    yum install openssl-devel
    this worked for updating to 1.4.16 plugins

  5. Thanks again. As stated by Rothgar, this also works on Redhat with openssl-devel

  6. I received the same error message within Centos 6.4 and yum install openssl-devel -y corrected the issue for me.

  7. i have follow errors:
