Does anyone run Bro build as a 64-bit binary on a 64-bit platform? Thanks,   .Seth ---

I'm running Bro 1.5 on x86\_64 Linux. No obvious issues here -- except with broccoli. ---

It has been running fine on CentOS 5.3 x86\_64 since late 2009. Tyler ---

I am as well.. but I haven't had any problems with broccoli. ---

Ok, that's partly why I asked. It looks like broccoli needs to be built with -fPIC. I'll file a ticket in the tracker.   .Seth ---

I built 32- and 64-bit RPM's of bro 1.4 without needing to force -fPIC anywhere. I haven't had a chance to update them to 1.5 yet, so it's possible that has changed. Michael ---

I encountered underruns and corruption while using bropipe to send datatypes involving an int (count, port...) to Bro. The underlying issue seems to be that broccoli is sending a 32-bit int and Bro is expecting a 64-bit one. In what is probably the Wrong Way(tm) to approach the problem, I patched broccoli to send 64-bit ints with the high 32 bits zeroed. ---

Did you have Bro built with --enable-int64?   .Seth ---

After some more investigation, here's the ticket:   [http://tracker.icir.org/bro/ticket/256](http://tracker.icir.org/bro/ticket/256)   .Seth ---

Initially I did. That seems to be what caused the problem. Rebuilding without --enable-int64 appears to have resolved the underrun errors in bro. ---

Yet another ticket needs filed for that one.   .Seth ---
