Cactid Execution Error

[Wildmike556]

I have installed Cacti 0.8.5a on RedHat Linux 7.3, and everything appears to be functioning properly. I wanted to get a performance boost so I can monitor a large network with several hundred interfaces.

I configured/made/installed cactid, and now when I try to execute the binary, I get the following error:

Code: Select all

[root@161 bin]# ./cactid
./cactid: error while loading shared libraries: libnetsnmp.so.5: cannot open shared object file: No such file or directory
[root@161 bin]#

I have installed net-SNMP 5.1.2 on this machine, and the libnetsnmp.so.5 file resides in /usr/local/lib, where it was placed by the installer. I've tried copying this file into /usr/local/cactid and /usr/local/cactid/bin, but every time it says it can't open the file.

Any ideas would be greatly appreciated![/code]

You have checked the permisions on those files right?

[Wildmike556]

Actually I haven't checked the permissions, but I've been trying to execute cactid as the superuser, so that wouldn't make a difference, would it?

Thanks for the reply.

There is an environment variable missing in your make configure/make routing pointing the the Net-SNMP shared libraries. I an not a *nix user, but I did work with a gentleman over the weekend who had the same exact problem. The path was LD_???. Sorry I can't be of more assistance. Try Google......

Thanks to TheWitness for pointing me in the right direction on this. I did a google for the problem and found a page that had a solution: http://trantor.imit.kth.se/courses/2g13 ... ommon.html

Basically, what I had to do was append the path '/usr/local/lib' onto the environment variable LD_LIBRARY_PATH. For those of you who might not know how to do this, here's the command:

Code: Select all

[root@mushroom /]# export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/usr/local/lib

I don't know how to make this information be appended to the variable at every startup, so you'll need to find that out, but that's the jist of it.

Hope this info is useful for someone else.

You should be able to add it to your login scripts. Add it to the bashrc file of the user or something.
