snortsam compilation problem

[Paolo Supino]

Hi

 I'm trying to compile snortsam (2.50 and 2.52) on OpenBSD 4.0 and I 
get the following compilation problems: gcc -O2 -DOpenBSD  -DBSD -c ssp_pf.c
ssp_pf.c: In function `PFBlock':
ssp_pf.c:705: error: storage size of `t_rule' isn't known
ssp_pf.c:794: error: invalid application of `sizeof' to an incomplete type
*** Error code 1
  Anyone can help me solve this compilation problem?



TIA
Paolo
