[Scons-users] How do I compile F90?

[Ian Ross]

Assuming that ifort is in your path, you can say

env=Environment(TOOLS=['ifort'])

to create your environment.  This will make sure that ifort is used for
compiling and linking and will also set the relevant compiler flags
correctly.

I'm not completely sure, but I think you can specify and explict path to
look for ifort and its supporting tools by doing something like this:

env=Environment(TOOLS=['ifort'], ENV={'PATH': os.environ['PATH'] +
os.pathsep + '/home/apps/intel/composer_xe_2013_sp1.0.080/bin/intel64'})

(That might not be the best way to do things.  Perhaps someone else can
comment?)
