Scons do not succeed to compile a file which do this :

• define a module
• define another module which include a file (which contain a subroutine using the previous module). The fact that this module include a file using previous module is crucial !
• use both module inside the main program It raises a "dependency cycle" of kind "mod_name.mod -> mod_name.mod".

Of course the compiler launched directly from a terminal compile without any problem.

I attached a test program to reproduce error.
I don't see how to fix the problem, except putting module definition in separate file and compile them along with the main program.

Circular dependencies will need the batch framework from issue 1086. Revisit
when that issue is resolved.

Adjust triage of issues.

Issue 1086 (batch build action support) has been added. Changing the target milestone to -unspecified- so the bug party can discuss this again to see if we want to move it up from 3.x.

Bug party triage. Don't try to do everything at once; Greg to create dependent issues to fix problem by stepwise refinement.

David, your name came up as a potential contributor to this issue as it's sorta related to FORTRAN. See the IRC log[1] for the discussion of this issue; it has some more information on the actual problem to be solved. I'm hoping you can do the Tool integration while I do the mathematical heavy lifting.

The bug party put this in 3.x, but it's more of an on-going project that shouldn't extend beyond 3.x, so I unilaterally marked it as 'anytime'.

de-assigning all tickets assigned to Greg Noel (no longer working on SCons)
