[Scons-users] problem copying files to variant directory

[Mark Diekhans]

Hi all,

I am building a number of modules with duplicate=False, wanting
to copy only a selected set of files to build to be shared by
other modules.

With the directory structure with
     - sconscript
       somedir/include/

the include files can be explicitly copied to the variant directory (module two in
the below example).

However with the directory structure with
     - sconscript
       include/

a circular dependency is generated (module one in
the example):

    scons: *** Found dependency cycle(s):
      build/one/include/oneA.h -> build/one/include/oneA.h
      build/one/include/oneB.h -> build/one/include/oneB.h

This happens using either Install or Copy.

Example is here:

I suspect the best approach is to allow scons to copy everything, however
I am curious is causing this problem.

Thank you,
Mark
