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

I think (but It's just my opinion) the linker have a bug here...

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... 5- Yet Another link problem : > g++ -o bro main.o net\_util.o util.o parse.o scan.o re-parse.o re-scan.o rule-parse.o rule-scan.o Active.o Anon.o Attr.o BackDoor.o BroString.o CCL.o CompHash.o Conn.o DFA.o Debug.o DebugCmds.o DbgBreakpoint.o DbgWatch.o DbgHelp.o Desc.o Dict.o Discard.o DNS.o DNS\_Mgr.o EquivClass.o Event.o Expr.o File.o Finger.o Frag.o Frame.o FTP.o Func.o Hash.o HTTP.o ICMP.o ID.o Ident.o InterConn.o IntSet.o List.o Logger.o Login.o MIME.o NFA.o NTP.o NVT.o Net.o NetbiosSSN.o NetVar.o Obj.o PktSrc.o PolicyFile.o Portmap.o PriorityQueue.o Queue.o Reassem.o Rlogin.o RE.o RPC.o Rule.o RuleMatcher.o RuleAction.o RuleCondition.o Scope.o Sessions.o SMTP.o SSH.o SteppingStone.o Stmt.o TCP.o TCP\_Rewriter.o Telnet.o Timer.o Type.o UDP.o Val.o Var.o XDR.o cq.o md5.o setsignal.o version.o nb\_dns.o -ltermcap -ledit libedit/\*.o -lpcap -lm -L/usr/local/src/bind-9.2.2/lib/bind/ -lbind > irs\_data.c:117: Undefined symbol `\_pthread\_mutex\_lock' referenced from text segment > irs\_data.c:119: Undefined symbol `\_pthread\_key\_create' referenced from text segment > irs\_data.c:120: Undefined symbol `\_pthread\_mutex\_unlock' referenced from text segment > irs\_data.c:122: Undefined symbol `\_pthread\_getspecific' referenced from text segment > irs\_data.c:130: Undefined symbol `\_pthread\_setspecific' referenced from text segment > collect2: ld returned 1 exit status > gmake: \*\*\* [bro] Error 1 Here, it's just a pthread librarie which is not link well.
