I guess I could add dependencies between all source files in the group, but as there are many files spread out over different SConscript files, this seems cumbersome. I do have a list of all object nodes though, which is used for linking, so an operation on this list that will instruct SCons that these objects need to be rebuilt together would be great.


Try monkey-patching the emitter for the builders you're using.
That might be an ugly but functional way to do it.
