Cross-architecture compiling
Jan Dušátko
I would like to ask people in this conference for advice regards
cross-architecture compiling.
Right now I have 32-bit system, where I need to boot over TFTP/NFS diferrent
architectures (i386/AMD64). I need to populate appropriate directory
structure using some "generalized" kernel configuration, each platform have
thein own kernel.conf.
I did those steps bellow, but this not work. Can someone help me?
Regards
Jan

At my previous $JOB we configured an amd64 system to load i386 diskless
stations.

"Not work" is not a diagnostic message. Please, be more specific here.

I'm not sure if those varialbes are needed.

Well, does this really work? Is it the same as KERNCONF=GENERIC?
Not sure.

I'm not sure about TOOLS_PREFIX (do not recall we used it).

I'd say this is not needed.

And that should be "make distribution DESTDIR=$DESTDIR".

That directory should already present.
And the rest I don't understand (may be OK).

Hi,
I don't have experience setting up a cross-build environment for
FreeBSD, but you may want to read this:
http://bsdimp.blogspot.com/2006/09/cross-building-freebsd.html
However, I have more experience setting up PXE (TFTP + NFS) booting
systems of FreeBSD. You should read this
document which I wrote:
