Cannot load modtcl (undefined symbol)

  • When I want to load modtcl.so, ZNC gives me an error:

    Loading Global Module … [ Unable to load module  [/usr/lib/znc/modtcl.so: undefined symbol: _ZN7CModule15OnWebPreRequestER8CWebSockRK7C] ]
    Unrecoverable config error.

    Any solution for this?

  • I'd guess that your modtcl is compiled against a different version of znc. Does recompiling help?

  • That was the problem. I got both znc and modtcl through apt, and the versions didnt match.

    Thank you!
