[Scons-users] Build Order

Hello Jim,

it should just work...if your Builder correctly returns the list of 
copied targets in the include directory (you might need an Emitter for 
this), and the CPPPATH variable points to your includes, such that they 
get detected as implicit dependencies by SCons.
Then it *is* guaranteed that the required headers get copied before a 
target's build.

So I'm wondering why you think you need additional methods like Requires 
or Depends. But maybe I'm missing something. Do you have something like 
a simple example (SConstruct + Builder) that you can post?

Best regards,

Dirk
