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/

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

Problem with LOCK_PROFILING stats in 7.2

Hi, I'm using LOCK_PROFILING to, well, profile some locks in the module I'm working on. I also have INVARIANTS turned on. Numbers I'm getting look correct, however, name of the lock is strange (for some of the locks I'm using): 25725 51777294 10979957 7331938 7 1

SMP aware programming

Hi, I'm about to port ModelNet (a large-scale internet emulator) from FreeBSD 4 to FreeBSD 7. It is implemented as a module. Well, changing couple of headers and structs will probably solve the thing, but I would like to make it SMP aware. Since it emulates a lot of nodes, each of which i

Hi, I'm trying to install FreeBSD 7.0 on our new server (Intel Xeon 2x4- core machine), which has a 250GB SATAII disk. I used -bootonly CD image, and assigned whole disk to FreeBSD. Breakdown is: / - 2GB swap - 4GB /var - 9GB /tmp - 4GB /usr - 213GB As soon as I start copying files from FTP,
