sample scons source

driver_sources = [ ... ]

# original
#d = [env.Object(src, src) for src in driver_sources]
#env.Library(d)
# my comments:
# env.Object(src, src) is weird because you're using the same name 
# for source and target. 
# I prefer just to let scons sort out the object names:
env.Library('libdriver', driver_sources)

env_flag = env.Clone()
env_flag.Append(CPPDEFINES = ['FLAG'])

# in the new env, we can't let scons sort out the object names itself 
# because that causes name conflicts
# the original solution ends up with weird object names
#d_wf = [env_flag.Object(src + '.flag', src) for src in driver_sources]
#env_flag.Library(d_wf)

# I ended up with the following:
# first generate a list of object names
flag_objects = [os.path.splitext(src)[0] + '_flag' + env['OBJSUFFIX'] for src in driver_sources]
# now tell scons how to make the objects
d_wf = [env_flag.Object(tgt, src) for tgt,src in zip(flag_objects, driver_sources)]
env_flag.Library(d_wf)
