I’m trying to install latest version of Snort in backtrack4 bt4
first problem,
when I do "apt-get update" and "apt-get install snort"
it keep saying I have the latest even though it’s only v 2.8.0.2
is the distribution site normally late on update?

so I’m trying to compile it on my own on BT4.
I had to install libpcre3.dev to pass ./configure
but I’m stuck at make. getting following errors, any ideas?

In function ‘open’,
inlined from ‘server_stats_save’ at server_stats.c:349:
/usr/include/bits/fcntl2.h:51: error: call to ‘__open_missing_mode’ declared with attribute error: open with O_CREAT in second argument needs 3 arguments

If you want the latest version of Snort, then you need to be using 2.8.5.3. It looks like you have 2.8.3.1. Try downloading and compiling that first.
