[Scons-users] using depends properly

[Bill Deegan]

There is really no SConscript object, though  there is a File Node..

Honestly your simple example is pretty confusing.

Why not just explain what you are trying to do?

When I see things like this:
target = env1.Foo(File(env1.subst('$O') + '/' + d).abspath, prev)

I know there's a bunch you're still not getting.

target = env1.Foo('$O/%s'%d), prev)

Is sufficient. SCons will drop the abspath and not use it.

As far as I can tell you want to build a bunch of objects and build up a
list of those objects to use somewhere?

Do you want the target of this:
env2.Command('foo.out', '/dev/null', "echo this should be printed after all
the sleep and touch ends")

To depend on that list of objects?
