Hi all,
we were trying to install click 2.0.1 patchless on a CentOS 6.0 (kernel version
2.6.32-71) and we got several instances of thefollowing error:
click-2.0.1/include/click-linuxmodule/include0/linux/netdevice.h:2080: error:
‘NETREG_REGISTERED’ was not declared in this scope
This is something that was already discussed and solved in the list (see
below). However, it seems that the patch suggested by Eddie was not implemented
in click 2.0.1 (could not even find it applied in github). So we tried to apply
the suggested changes and the compilation phase completed successfully (you can
find the relevant patch at the bottom of this message, if you are interested).
However, during the linking phase we got the following error:
-----------------------------------------------------------

-----------------------------------------------------------
Any clue about what the problem could be? Any suggestion on how to proceed?
(Either try and solve this one or just forget about it and use a different
kernel/distribution?)
Thank you.
