Hi folks- I am setting up FreeBSD 5.1-RELEASE on a 386DX. I'm mostly doing it as a learning exercise (or perhaps because I'm a masochist), but the machine may be used as a firewall at some point. I have the OS installed with a custom kernel, and things are actually going quite well. There are (of course) some problems though. Most of the userland utilities work great, but some just dump core. The one I miss in particular is groff (for manpages, etc). I suspect that the problems are a result of CPU instructions that the poor 386 doesn't understand. I do have a separate build machine (soon to be running 5.1 as well), so I'd like to recompile everything (kernel, userland, and ports-to-be-made-into-packages) for the 386 with the appropriate flags to gcc and friends. Hopefully that will take care of the issues I'm seeing. So my question is, what flags should I use and where should I put them? I'd like to be able to switch easily between builds for the 386 and "normal" builds (for everything else). Can I just put an override in /etc/make.conf or do I have to futz with /usr/share/mk/bsd.cpu.mk? (In the case of the latter, detailed hints would be appreciated.. I don't grok Make all that well yet.) Thanks, JN
