Building modules in Fortran needs to be done in a specific order, e.g. if a file A.f
needs module defined in B.f
, then B.f
needs to be compiled first. How can I impose such build order in Scons? If I provide it with a list of source files, it arranges them alphabetically (so A.f
is compiled before B.f
). I read about Requires()
and Depends()
functions, but wasn't able to get them to work for me.
I would be happy with just listing source files in order I need them compiled (so disabling reshuffling them in alphabetical order), but any other method would be welcomed as well.
As per Kyle's request, here's my Sconscript and a build log:
# Main program building script
Import('env')
PROGRAM = 'main.exe'
SRC_PREFIX = './src/'
SRC = [ 'array_1D_module.f',
'array_2D_module.f',
'array_3D_module.f',
'thomas_algorithm_module.f',
'histogram_module.f',
'histogram_computer_module.f',
'density_parameters_module.f',
'diffusion3D_aos_z_sub_solver_module.f',
'diffusion3D_aos_y_sub_solver_module.f',
'diffusion3D_aos_x_sub_solver_module.f',
'diffusion3D_aos_solver_module.f',
'nonlinear_diffusion_utilities_module.f',
'nonlinear_diffusion_parameters_module.f',
'derivative_magnitude_computer_module.f',
'nonlinear_diffusion_module.f',
'main_module.f',
'main.f' ]
# Attach prefix to each source file
for i in range( len(SRC) ) :
SRC[i] = SRC_PREFIX + SRC[i]
env.Program(target = PROGRAM, source = SRC)
This produced:
scons: Reading SConscript files ...
scons: done reading SConscript files.
scons: Building targets ...

So density_parameters_module.f
was compiled before thomas_algorithm_module.f
, even though it comes after it in my list.
