Getting the error
check_http.c:150:12: warning: ignoring return value of âasprintfâ, declared with attribute warn_unused_result [-Wunused-result]
When trying to compile the nagios plugins 1.4.16 in Ubuntu 12.04, it comes down to SSL.
Running : apt-get install libssl-dev
Then ./configure and make again fixed the problem.
As a side note I was also having problems with NRPE not installing. This one was down to not reading the error. the user and group nagios doesn’t get created by the nrpe install script. So just have to add the user and group and then the install was fine.
