Heh

Greetings again all,

Thought I better pop in again for a bit to lot y'all know I'm not dead
( I just smell funny ).

I've been meaning to get back onto this exact problem now for about 2
months but work pressures have sidelined me rather heavily. Hopefully in
the next month once I clear some of the projects I'm working on I'll
finish this off, as I dont just want to be able to have the option of
lib/lib32/lib64, but to allow us to follow, say, the route the debian
folk may be taking ( /tgt-triple/lib , /usr/tgt-triple/lib for each
supported arch).

For blfs I have built quite a range of packages for multilib, but it can
be a little fun, you do need a binary wrapper for quite a few things
where you must have both the 32 and 64bit binaries (eg perl/python) or
shell scripts ( bin/foo-config ), as well as check installed headers are
the same ( else you need to create header stubs ).

For those interested most are in lfs-svn under
cross-lfs/scripts/untested/{blfs,kde,gnome}-scripts but may be a little
out of date (its probably been 2 months).

Anyhoo, got doco to write (on a Sunday urgh) and better get back to it
or folks wont get paid ;-)

Best Regards
[R]
