[Click] compiling problem with gridgenricmetric in click

[zi feng]

Hi all,

I am having a problem compiling click. Everything was working before. I just
did a 'make clean' then I configured it again, then 'make elemlist' and
'make'. Then I get the following errors with reference to gridgenericmetric:

--------------------------------------

I have checked GridGenricMetric.hh and everything looks good. What I do not
get is that it used to work well before I 'make clean'.

If anyone has any clue about this problem or any suggestions, I will really
appreciate it a lot.

Thanks!!
