------------------------------------
The "input in flex scanner failed" error is generated when a call to:
require($path)
is made with $path specifying a directory and not a file. Or the target
file can not be found.
http://www.php.net/manual/function.require.php3
------------------------------------
Did you specify any configuration options when you ran configure?
Possibly you pointed to an invalid location? (I simply ran ./configure
and have not experienced that problem.)
Before you start thinking about recompiling, I'd suggest you ignore the
binary database and run with the text files only. Your only performance
hit will be in starting/restarting squidGuard (and how often will you be
doing that?). The extra time at startup will probably not even be
noticeable until you have more than 50,000 lines in your domains or urls
files. Just delete the .db files and forget the -C command.

Okay, now I understand that part of it, but when I run
/local/squid/bin/squidGuard -C all, I receive an error and it does not
create the db files. The error message was "input in flex scanner
failed"
# /local/squid/bin/squidGuard -C all
input in flex scanner failed
#
# /local/squid/bin/squidGuard -C
/local/squid/squidGuard/dbhome/porn/domains
input in flex scanner failed
#
I did take your suggestion, and implement the different file for ads. I
was
going to all ready do that, but just wanted to get the errors settled
first.
Thanks,
Manuel
