I was trying to install nagios-plugins-1.4.16 on my machine and when I did a make it gave this error:

check_http.c: In function 'process_arguments':
check_http.c:312: error: 'ssl_version' undeclared (first use in this function)
check_http.c:312: error: (Each undeclared identifier is reported only once
check_http.c:312: error: for each function it appears in.)
make[2]: *** [check_http.o] Error 1
make[2]: Leaving directory `~/nagios-plugins-1.4.16/plugins'
make[1]: *** [all-recursive] Error 1
make[1]: Leaving directory `~/nagios-plugins-1.4.16'
make: *** [all] Error 2

I then tried installing version 1.4.15 and had no problems. I didn't get this error on the last machine I installed 1.4.16 on.

The one that got the error is:
Red Hat Enterprise Linux Workstation release 6.4 (Santiago)

and the machine didn't give an error is:
SUSE Linux Enterprise Server 11 (x86_64)

is there an issue with redhat? Should configure have caught the problem?

Do you have openssl and openssl-devel?
Is openssl installed:

Code: Select all

which openssl

Do you have the headers (for Redhat/CentOS):

Code: Select all

yum list installed | grep openssl

ah, thanks. openssl is installed, but openssl-devel is not. I'm pretty sure that's the issue, since I was doing a configure for nrpe and got this error:

checking for SSL headers... configure: error: Cannot find ssl headers

Shouldn't configure for the nagios plugins have caught that error as well?

SUSE does not use yum

Missed that you were using SUSE. The package you are looking for is:

Code: Select all

libssl-dev

If you use zypper:

Code: Select all

zypper install libssl-dev

Or just grab it with yast. Once the package is installed, rebuild nrpe/nagios plugins.

no worries. It worked on SUSE, I was having the issues on Redhat. Once I installed openssl-devel everything worked!
