NetXMS Support Forum

Hello,

I today was trying to install netxms-agent on Debian Strech, which was successful, but after installation - process of starting service failed on

nxagentd[7708]: /usr/bin/nxagentd: symbol lookup error: /usr/bin/nxagentd: undefined symbol: _ZN...nsportEv

which is happening after purging, readding netxms.

Any advice?

Thank you

Can you show output of "ldd /usr/bin/nxagend", please?

yes,

sorry for late reply

You have leftover libraries in /usr/local/lib which clash with package libs in /usr/lib/x86_64-linux-gnu/

Cleanup /usr/local/lib and issue should be resolved .

Thank worked...

Just to be clear, I run command sudo find /usr/local/lib -name "*ne*" -exec rm rf {} \; && sudo find /usr/local/lib -name "*nx*" -exec rm rf {} \; ...

Don't do that without checking what you delete

Thanks for pointing out by Victor Kirhenshtein

Hi,

most of libraries have prefix nx (like libnxagent), so searching only for "ne" may not be enough. I suggest to check with ldd that agent didn't pickup any "nx" prefixed library from /usr/local/lib.

Best regards,
Victor
