Hi,

I'm trying to install the nrpe version 2.11 on a remote client host Centos 5.1 and I'm getting this error below. Can anyone help? Thanks

Code:

[root@test1 nrpe-2.11]# make all
cd ./src/; make ; cd ..
make[1]: Entering directory `/usr/local/src/nagios/nrpe-2.11/src'

From the code it seems to have to do with (incompatible?) version of OpenSSL. Since you're using CentOS, is there any compelling reason not to use the DAG repo Nrpe?

After looking at alternate solutions, the source of the get_dh512 is an invalid generation of dh.h.

The generation of dh.h occurs when the command:

openssl dhcparam -C 512

Is run as part of the configure script.

If you'll look at README.SSL, it discusses this process.

If you create your own dh.h, the code will compile properly. To do this, use 'openssl dhparam -C 512', and capture the C-code output of the command. Place this code into include/dh.h and voila, the code will compile.
