Hi,
I tried to install the Anonymous Click version and following is the error I
got.
Can some point out whats the mistake I am making? I want to install click at
userlevel.
on doing ./configure this is the error I got:
---------------------------------------
configure: error:
=========================================
Can't find Linux System.map file '/lib/modules/2.6.11-
1.1369_FC4/build/System.map'.
=========================================
