[Scons-users] Suffix for Fortran 90 source files

Dear Bill,
thank you, but I got the following error.
scons: Building targets ...
ilink /O:main main.o
sh: 1: ilink: not found
scons: *** [main] Error 127
scons: building terminated because of errors.
Just to get the build done, I found that the following works:
env = Environment(
FORTRANFILESUFFIXES=['.F', '.f', '.F90', '.f90'])
However, I don't understand how `.i90` or `.I90` shows up by default.
I found that SCons v.3.0.0 on another machine does not have this issue.
I started to see that SCons looks into some information in each
machine and sets up the construction variable. I would like to know
the process better.
Sincerely,
Norio
