[Scons-dev] Cleaning a target on rebuild

[Bill Deegan]

William,

You are thinking about order here.  The better way to think in SCons is
about dependencies and actions.
SCons is designed for dependencies and actions and not for forcing order of
execution.

It seems likely what you really want is to use :
AddPreAction(target, action) , env.AddPreAction(target, action)

See manpage: http://www.scons.org/doc/2.3.2/HTML/scons-man.html

Where the action would be removing whatever files you want cleaned before
the target in question is built.


-Bill
