[Scons-users] Grouped dependency

[Arvid Rosén]

Hi,

And thanks for your replies. I know it is a bit odd, and something I try to avoid. But the “compiler” in this case use a database to store statistics regarding the project, and it needs to start with a fresh and clean database if any of the files are changed. I am trying to work around this, but it is not super easy, so if this could be handled by SCons it would be cool.

Cheers,
Arvid

Also keep in mind that if some other change alters the command line, they would all be rebuilt as well.

Arvid,

You cannot make them all depend on each other because that will create dependency cycles. Is there a legitimate reason for this requirement that cannot be solved by moving out the shared artifact into a header?

V/R,
William

Hi Arvid,

However, if any of A.cpp, B.cpp or C.cpp are changed, I want to rebuild all 3 files

This seems like an odd request, and AFAIK there's no built-in mechanism to do this in SCons. If A.cpp is changed, why do B.cpp and C.cpp need to be re-compiled?
