[Scons-users] Suffix for Fortran 90 source files

[Bill Deegan]

Here's the code which generates the default tools to load per platform.

It will walk each type of tool and try to initialize each until it finds
one of each type.
In the process of doing so, it will configure various Environment()
variables
(you can see the list in the manpage:
http://scons.org/doc/production/HTML/scons-man.html )

I think the problem is that ifort doesn't set .f90 as a suffix by default.

Can you add the following to your ifort.py in SCons/Tool

Change:

from .FortranCommon import add_all_to_env

to

from .FortranCommon import add_all_to_env, add_f90_to_env


After:

SCons.Tool.SourceFileScanner.add_scanner('.i90', fscan)

Add:

add_f90_to_env(env)


Then remove the FORTRANFILESUFFIXES from your Environment() and see if
that works.
