[Scons-users] Mixing VariantDirs with "in-tree" build

[pasdVn]

Thanks for your quick reply!

I thought that SCons is looking up a node via srcnode() and thus in the original location, if it is not found in the current variant dir, but obviously this is not the case here, because A/B/foo is a generate file (i.e. a target), right?
