[Scons-users] My dependency tree is incorrect, I want to depends on IDL generation

[Bill Deegan]

You're emitter is dropping the passed in targets, this may be the cause of
your issue.

You example is just far too many lines at this point.
Make it one file, demonstrate with a single input file, then provide those
two files back...

It looks like you basically have an emitter in your SConstruct and in your
builder definition.
