When I want to install nrpe plugin,I get an error.
# ./configure
…
checking for type of socket size... size_t
checking for SSL headers... SSL headers found in /usr
checking for SSL libraries... configure: error: Cannot find ssl libraries
checking for SSL headers… configure: error: Cannot find ssl headers
You have to install openssl-devel package.
yum install openssl-devel
After that, i was able to configure and install the nrpe plugin on the client system.
