SCons supports an
which can be used to terminate SCons
while reading the SConscript files,
usually because you've detected a condition
under which it doesn't make sense to proceed:
if ARGUMENTS.get('FUTURE'): print "The FUTURE option is not supported yet!" Exit(2) env = Environment() env.Program('hello.c')
% scons -Q FUTURE=1 The FUTURE option is not supported yet! % scons -Q cc -o hello.o -c hello.c cc -o hello hello.o
Exit function takes as an argument
the (numeric) exit status that you want SCons to exit with.
If you don't specify a value,
the default is to exit with 0,
which indicates successful execution.
Note that the
is equivalent to calling the Python
(which the it actually calls),
Exit is a SCons function,
you don't have to import the Python
sys module to use it.
