when I run the snort with this command:
root@gl-desktop:/home/gl/Applications/snort-2.8.3.2# /usr/local/bin/snort -c /usr/local/snort/conf/snort.conf -l /var/log/snort -i eth0 -u root

another problem was occured:

database: 'mysql' support is not compiled into this build of snort


ERROR: If this build of snort was obtained as a binary distribution (e.g., rpm,
or Windows), then check for alternate builds that contains the necessary
'mysql' support.

If this build of snort was compiled by you, then re-run the
the ./configure script using the '--with-mysql' switch.
For non-standard installations of a database, the '--with-mysql=DIR'
syntax may need to be used to specify the base directory of the DB install.

See the database documentation for cursory details (doc/README.database).
and the URL to the most recent database plugin documentation.
Fatal Error, Quitting..
