yes, i figured that out quickly enough. but i still might be able to
make this work since i want to create an entire build infrastructure
(using make or scons, perhaps), where my current project (i've gotten
kind of nervous using that word now :-) involves pulling together a
bunch of different software components to create an entire embedded
system.
imagine that this embedded system will be built from two types of
software components: open source stuff (perhaps i'll keep all that in
one svn repo, tracking 3rd party sources), and proprietary, internal
bits (perfect for another repo).
now, if i have your typical recursive make structure, at each level,
the makefile will simply be responsible for knowing which software bit
to pull out of which repo. in that sense, it's not like those repos
have to communicate with each other -- they're really independent, and
it's just the make structure which has to access them, a bit at a
time, to checkout the appropriate component.
so it's not like i'd have a separate repo for *every* different bit of
software. but i might have a separate repo for each related
*collection* of software bits. and it should be obvious that those
two repos would never want to communicate with each other, since they
store wholly different kinds of data. it's only the make structure
that would access them.
anyway, i still haven't hit the sections on svn:externals or managing
vendor branches -- i suspect i'll get lots of info when i get there.
rday
p.s. if anyone's done just this sort of thing -- used svn as part of
a build infrastructure to build an entire embedded system -- by all
means, i'd love to hear from you.
