[Scons-users] Randomly, Scons can not find the header files(#include)

[Bill Deegan]

What's the command line when it fails?
Does it have the -I's?

A WAG would be that another file has the proper dependencies on the file
and thus it's getting copied to build dir, while the one(s) which fail do
not. Thus if the order of compilation changes it may not be copied in time..
