Problem with LOCK_PROFILING stats in 7.2

Cluster-wide installation of FreeBSD

Hi, I have a machine running FreeBSD 7.1, and now I would like to "replicate" it to other machines in our cluster. Other machines have smaller disks, and a different processor, but all are amd64. Is there a way to do this kind of installation (either by copying content, or installing and

Compiling C++ modules

Hi, what are the recommended CXXFLAGS for C++ code which should go in kernel module? Yes, I know C++ in kernel is a bad idea, but those are the requirements... Best, Nikola ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/

Hi guys, I'm trying to port Click modular router to FreeBSD 7.0. Along the way, I changed it quite a bit, but I managed to get it to compile. Well, when I try to load it (via sudo make load), this is what I get: link_elf_obj: symbol ether_poll_register undefined kldload: /usr/home/knl/work/
