[Scons-users] Creation of an archive of source files with Node.all_children()

Thanks for the explanation. Unfortunately the workaround that consists in
getting all headers with Glob is not really adapted to my situation.
I use boost libraries and I would like to archive boost headers that are
included from my code, but not all boost headers...
I understand why FindSourceFiles cannot process implicit dependencies, but
getting headers is really my goal.
Could you explain me why using get_allchildren is not recommended and leads
to errors ? Or would you have any other workaround more acceptable to me ?
Many thanks for the time you spend to help me, I really appreciate.
