I am so bored of this behavior. Therefore, in the SConstruct file , we have the last line, similar to this:
import compilers, os
env = Environment(ENV = os.environ, TOOLS = ['default'])
def set_compiler(compiler_name):
env.Replace(FORTRAN = compiler_name)
env.Replace(F77 = compiler_name)
env.Replace(F90 = compiler_name)
env.Replace(F95 = compiler_name)
def set_flags(flags):
env.Replace(FORTRANFLAGS = flags)
env.Replace(F77FLAGS = flags)
env.Replace(F90FLAGS = flags)
env.Replace(F95FLAGS = flags)
mod_dir_prefix = {
"gfortran": "-J ",
"ifort": "-???",
"pgfortran": "-module "
}
flags = {
("gfortran", "debug"): "-O0 -g -Wall -Wextra -pedantic -fimplicit-none -fbounds-check -fbacktrace",
("gfortran", "release"): "-O3",
("pgfortran", "debug"): "-O0 -g -C -traceback",
("pgfortran", "release"): "-O4"
}
if not GetOption('clean'):
print "\nAvailable Fortran compilers:\n"
for k, v in compilers.compilers_dict().iteritems():
print "%10s : %s" % (k, v)
compiler = raw_input("\nChoose compiler: ")
set_compiler(compiler)
debug_or_release = raw_input("\nDebug or release: ")
set_flags(flags[(compiler, debug_or_release)])
env.Replace(FORTRANMODDIRPREFIX = mod_dir_prefix[compiler])
env.Replace(LINK = compiler)
env.Replace(LINKCOM = "$LINK -o $TARGET $LINKFLAGS $SOURCES $_LIBDIRFLAGS $_LIBFLAGS $_FRAMEWORKPATH $_FRAMEWORKS $FRAMEWORKSFLAGS")
env.Replace(LINKFLAGS = "")
env.Replace(FORTRANMODDIR = '#Mod')
Export('env')
SConscript('Sources/SConscript', variant_dir='Build', duplicate=0)
compilers.py is my own module for finding Fortran compilers that are available.
In the Sources folder, we have a couple of Fortran source files.
Sources \ SConscript
Import('env')
env.Program('app', Glob('*.f90'))
Scons supports Fortran and everything works fine.
gfortran -o Temp\kinds.o -c -O3 -JMod Sources\kinds.f90
gfortran -o Temp\math.o -c -O3 -JMod Sources\math.f90
gfortran -o Temp\sorts.o -c -O3 -JMod Sources\sorts.f90
gfortran -o Temp\utils.o -c -O3 -JMod Sources\utils.f90
gfortran -o Temp\main.o -c -O3 -JMod Sources\main.f90
gfortran -o Temp\app.exe Temp\kinds.o Temp\main.o Temp\math.o Temp\sorts.o Temp\utils.o
scons: done building targets.
After renaming the variant_dir name to say #Binor #Build, an error message appears:
gfortran -o Bin\kinds.o -c -O3 -JMod Sources\kinds.f90
gfortran -o Bin\main.o -c -O3 -JMod Sources\main.f90
Sources\main.f90:3.11:
USE sorts
1
Fatal Error: Can't open module file 'sorts.mod' for reading at (1): No such file or directory
Of course, compilation order matters. But why does it depend on the variant_dir name? Sounds like a mistake, but maybe I'm doing something wrong.
P.S. duplicate.
