That's not easy to get rid of, it provides BPF filtering for packet source plugins that can't do that natively (like netmap). Do you happen to know if there's another way to do that with older pcaps?

Thank you. However it looks like we actually require more parts of the newer libpcap version - now the build fails because of pcap_offline_filter: https://build.opensuse.org/package/live_build_log/home:0xxon:bro/bro-nightly/RedHat_RHEL-5/i586 Johanna ___ bro-dev mailing list bro-dev@bro.org http://mailman.icsi.berkeley.edu/mailman/listinfo/bro-dev

I’m not that familiar either, but think it may be fine to provide our own preprocessor definition if it doesn’t exist. Robin, what do you think? Was there any other functionality of recent libpcaps that’s used now? Do we know what minimum version of libpcap should be required and checked at configure time? - Jon ___ bro-dev mailing list bro-dev@bro.org http://mailman.icsi.berkeley.edu/mailman/listinfo/bro-dev

One more question - currently Bro does not compile on systems that use libpcap < 1.1.1, because PCAP_NETMASK_UNKNOWN is not defined (example compile error: https://build.opensuse.org/package/live_build_log/home:0xxon:bro/bro-nightly/xUbuntu_10.04/i586) Could we perhaps test for the definition of that macro and either define it to something ourselves in that case, or just use another code-path? On a first glance, it does not look especially critical that we use it, but I am not really familiar with that case.

Yeah, patching it out should be easy for the moment. Here’s the relevant change from the bro repo: https://github.com/bro/bro/commit/d8890ea009fdb94ecffcf826bbfd23577396365e And the one from bro-aux: https://github.com/bro/bro-aux/commit/0b713c027d3efaaca50e5df995c02656175573cd I think that one place in bro-aux is the only place that’s using CMake 2.8 features right now, but let me know if you find otherwise and need any help. - Jon ___ bro-dev mailing list bro-dev@bro.org http://mailman.icsi.berkeley.edu/mailman/listinfo/bro-dev

I will try, it actually might be possible to make it a compile-time-only requirement. Just to check - is removing the dependency for 2.8 as easy as changing the minimal cmake version and removing a few lines from one of the cmake scripts? Because in that case I would be tempted to just automatically patch it out when building for those distributions (I have a few distribution specific actions in the build files in any case).

I think 6.6 has CMake 2.8.12.2 now. But yeah, before they were at 2.6.4. > Is there any important reason why we need 2.8? Not especially important, but newer versions of CMake were emitting some CMake policy warnings at bro-aux configure-time that I didn’t see a way to fix without using generator expressions, which became available in CMake 2.8. If you can’t upgrade to 6.6, is it at least an option for you to compile a newer CMake from source? - Jon ___ bro-dev mailing list bro-dev@bro.org http://mailman.icsi.berkeley.edu/mailman/listinfo/bro-dev
Re: [Bro-Dev] Compiling Bro on RedHat, CentOs 6 and earlier (cmake)
It looks like RH/CentOS 6.6 has cmake 2.8.12, and RH/CentOS 6.5 and earlier have cmake 2.6.4.
