histogram & missing library

[amprantino]

Hello all,

when I am trying to access histogram, I get an "Internal Server Error".
From apache2 logs, I get these:

[cgi:error] [pid 30784] [client 192.168.x.x:64470] AH01215: /var/www/nagios/cgi-bin/histogram.cgi: error while loading shared libraries: libgd.so.2: wrong ELF class: ELFCLASS64, referer: http://nagios/side.php
[cgi:error] [pid 30784] [client 192.168.x.x:64470] End of script output before headers: histogram.cgi, referer: http://nagios/side.php

Where should this libgd.so.2 be located?
I can find the file here: /usr/lib/x86_64-linux-gnu/libgd.so.2
Probably is search the library se wrong path

What version of Core are you running, and what OS is the server running?

What version of Core are you running, and what OS is the server running?

# uname -a
Linux davinci 3.16.0-4-amd64 #1 SMP Debian 3.16.7-ckt20-1+deb8u3 (2016-01-17) x86_64 GNU/Linux
# cat /etc/debian_version
8.5

# nagios -v
Nagios Core 3.4.1

This was probably working but due to debian updates during the last years it got broken

Did you move files (like histogram.cgi) from a 32bit system to a 64 bit system?

That is what this error usually corresponds to, the recommendation would be to re-compile Nagios Core.

[amprantino]

Probably not.
However, I will upgrade as its an old version. A new compile to the lastest 3.4 version will probably fix the problem.

[rkennedy]

Let us know how the new install goes. Our latest version is actually 4.1.1.

[amprantino]

I just upgraded to latest 3.x version (3.4.1), I have recompiled all cgis and the issue was solved.

Thank you

Thanks for sharing your fix! Is it alright if we lock this thread and mark the issue as resolved?

[amprantino]

ok
