Using multi-platform configuration
as described in the previous sections
will run the configuration commands
even when invoking
scons -c
to clean targets:
% scons -Q -c
Checking for MyLibrary... ok
Removed foo.o
Removed foo
|
Although running the platform checks
when removing targets doesn't hurt anything,
it's usually unnecessary.
You can avoid this by using the
GetOption(); method to
check whether the -c (clean)
option has been invoked on the command line:
env = Environment()
if not env.GetOption('clean'):
conf = Configure(env, custom_tests = {'CheckMyLibrary' : CheckMyLibrary})
if not conf.CheckMyLibrary():
print 'MyLibrary is not installed!'
Exit(1)
env = conf.Finish()
|
% scons -Q -c
Removed foo.o
Removed foo
