[Scons-users] SCons ignoring FORTRANPATH

[Damien]

All,

This comes up every few years on the list in some form or another. It is 
an annoying, fickle and somewhat temperamental aspect, but very 
effective, much like those of us who still have to have to compile 
Fortran :-).  I can't promise that this will fix your problem, but this 
is what we do to make our Fortran compiles work with gfortran on Linux.  
You can do this at the top of your SConscript.

With gfortran:

    env['FORTRAN'] = 'gfortran'

    env['FORTRANMODDIRPREFIX'] = '-J'
    env['FORTRANMODDIR'] = '${TARGET.dir}'
    env['FORTINCPREFIX'] = '-I'
    env['_FORTRANINCFLAGS'] = '$( ${_concat(FORTINCPREFIX, FORTRANPATH, 
INCSUFFIX, __env__, RDirs, TARGET, SOURCE)} $)'
    env['FORTRANCOM'] = '$FORTRAN -o$TARGET -c $FORTRANFLAGS 
$FORTRANMODDIRPREFIX$FORTRANMODDIR $_FORTRANINCFLAGS $SOURCES'
    env['SHFORTRANCOM'] = env['FORTRANCOM']
    env['SHF90PPCOM'] = env['FORTRANCOM']
    env['SHF95PPCOM'] = env['FORTRANCOM']
    env['F90PPCOM'] = env['FORTRANCOM']
    env['F95PPCOM'] = env['FORTRANCOM']

and with Intel Fortran on Windows:

   env['FORTRANPATH'] = fortincludepath

    env['FORTRANMODDIRPREFIX'] = '/module:'
    env['FORTRANMODDIR'] = '${TARGET.dir}'

    env['_FORTRANINCFLAGS'] = '$( ${_concat(FORTINCPREFIX, FORTRANPATH, 
INCSUFFIX, __env__, RDirs, TARGET, SOURCE)} $)'
    env['FORTINCPREFIX'] = '/I'

    env['FORTRANCOM'] = '$FORTRAN /Fo$TARGET /c $FORTRANFLAGS 
$FORTRANMODDIRPREFIX$FORTRANMODDIR $_FORTRANINCFLAGS $SOURCES'
    env['SHFORTRANCOM'] = env['FORTRANCOM']
    env['SHF90PPCOM'] = env['FORTRANCOM']
    env['SHF95PPCOM'] = env['FORTRANCOM']
    env['F90PPCOM'] = env['FORTRANCOM']
    env['F95PPCOM'] = env['FORTRANCOM']

Hope this helps,

Damien
