Re: Mulitple projects in a single Jamfile

Overriding the location-prefix on the library works great for some of
the libraries, Thanks :) Still don't quite have a feeling for how the
system ties together... Another related question, dealing with more
sub-directories:

I have something like this:
+-root
--+-util
----|-a.cc
----+-sub1
------|-a.cc

So, the following doesn't work:

lib util : util/a.cc util/sub1/a.cc : <location-prefix>util ;

I tried an alias, but the location prefix feature seems to be bound to
the target, and not the source files. So this doesn't work either:

alias sub1 : util/sub1/a.cc : <location-prefix>util/sub2 ;
lib util : util/a.cc sub1 : <location-prefix>util ;

What does work is this:

lib sub1 : util/sub1/a.cc : <location-prefix>util/sub1 ;
lib util : util/a.cc sub1 : <location-prefix>util ;

but then I end up with two libraries. I've seen references to binding
locations to obj targets, but then I'd need a declaration for each
object in sub1, which I'd like to avoid.

Is there a way to combine libraries? or another way to bind
location-prefix values to source files?

Thanks for helping out!
