Unable to start FAHClient

[LabNuke]

Fresh install of fahclient/fahcontrol/fahviewer

FAHClient: relocation error: FAHClient: symbol _ZTINSt8ios_base7failureB5cxx11E, version GLIBCXX_3.4.21 not defined in file libstdc++.so.6 with link time reference

Linux 3.13.0-170-generic #220-Ubuntu SMP Thu May 9 12:40:49 UTC 2019 x86_64 x86_64 x86_64 GNU/Linux

Google-foo doesn't find much on this. Any suggestions?

Thanks.

This is odd - when I go to /var/lib/fahclient - there are no files in that folder. I uninstalled fahclient and then re-run sudo dpkg -i fahclient_7.5.1_amd64.deb.

Thanks for your help.

Linux 3.13 was released in 2014. Your version of libstdc++ probably can't handle the client anymore. Either try to force a newer version of libstdc++ on your old system, which may cause some other problems, or better yet upgrade your system to a more fresh Ubuntu (which would be a sensible thing to do in general, since 3.13 is probably out of support already).

Just upgraded kernel -

Linux tpad 4.4.0-148-generic #174~14.04.1-Ubuntu SMP Thu May 9 08:17:37 UTC 2019 x86_64 x86_64 x86_64 GNU/Linux

Same results - still no /var/lib/fahclient log files and starting FAHClient gives:

Code: Select all

FAHClient: relocation error: FAHClient: symbol _ZTINSt8ios_base7failureB5cxx11E, version GLIBCXX_3.4.21 not defined in file libstdc++.so.6 with link time reference

You will also need to update libstdc++ library, which is part of GCC as far as I remember.

[LabNuke]

I ran a full update/upgrade after kernel upgrade also.

Code: Select all

	libstdc++.so.6 (libc6,x86-64) => /usr/lib/x86_64-linux-gnu/libstdc++.so.6
	libstdc++.so.6 (libc6) => /usr/lib/i386-linux-gnu/libstdc++.so.6
	libstdc++.so.6 (libc6) => /usr/lib32/libstdc++.so.6

Code: Select all

Well, good news is, your system got a small update. Bad news is, I'm out of ideas, sorry.

Edit: I think what happens is that the client was compiled against a library which had this symbol, but your version of this library doesn't have the same symbol for some reason (some test repository maybe?).

Which version of ubuntu are you running?
Try a dist upgrade to a more modern release?

[LabNuke]

Ubuntu 14.04.6 LTS trusty

[LabNuke]

Working on upgrading to 16.04 and will try again.

[LabNuke]

Upgraded to 18.04LTS - folding is now working.
