In order to make an OpenBSD port, I have to patch Bro but I can't find
any CVS.
Bro is not presently available via public CVS. Please send patches to
me so I can integrate them into future releases.

Hello,
I give you what I need to do to compile Bro (0.8a20) with an
OpenBSD(3.3) 17 mars Snapshot.
1- Problème with TCP_Rewriter.cc :
Here, the problème I've seen :
g++ -I. -Ilibedit -O -c TCP_Rewriter.cc
TCP_Rewriter.cc: In method `int TCP_TracePacket::Finish(pcap_pkthdr
*&, const u_char *&, int &, unsigned int, unsigned int)':
TCP_Rewriter.cc:350: no match for `bpf_timeval & = timeval'
/usr/include/net/bpf.h:122: candidates are: struct bpf_timeval &
bpf_timeval::operator =(const bpf_timeval &)
*** Error code 1
And to resolve it, I modify a few the "double_to_timeval"
function. Here, my changes :
#define MSG_PREFIX "TCP trace rewriter: "
#ifdef OPENBSD
static struct bpf_timeval double_to_timeval(double t)
{
struct bpf_timeval tv;
#else
static struct timeval double_to_timeval(double t)
{
struct timeval tv;
#endifdouble t1 = floor(t);
tv.tv_sec = (int) t1;
2- DNS error :

To solve it, I had to put the "-I$(BIND9_PATH)/include" flags in the
Makefile

Here, I have to put
"libedit/*.o" to the "-Llibedit" place.
I think (but It's just my opinion) the linker have a bug here... I've
got the 2.95.3 gcc version.

Off course, I put the bind include but I need to put the libbind
too. That what I do in the Makefile (LIBS variable) :
-L$(BIND_PATH) -lbind
I think (and It's again my own opinion) the best way to solve the DNS
problem is to put in the Bro sources the : bind-9.x.x/lib/bind
directory and modify the Makefile. In that way, the depedence with
Bind will be solve and I prefer not install bind on my firewall...

Here, it's just a pthread librarie which is not link well. Just add
-lpthread in the LIBS makefile variable.
make & gmake do the same things here.
I wish this will help you.
