I would assume I need to specify foo with some path like /home/harti/build/play/sub1/foo or just the directories. None of this works. scons tells me either that it doesn't know how to build it or it spits out a python error ('NoneType' object has no attribute 'get_contents'). harti _______________________________________________ Scons-users mailing list [email protected] https://pairlist4.pair.net/mailman/listinfo/scons-users
