Verbal consensus was reached this week that, with this change, no one
may "dirty" the build. It is irritating and danger-prone to have
broken, noisy makefiles. And cleaning up broken makefiles after the
fact is incredibly time consuming: this work consumed 6+ hours of
solid effort.
So: Your makefiles have to be written correctly from here on out.
- An incremental build when nothing has changed must do nothing
except traverse makefiles. Like this:
$ make
/net/xanadu/aux0/ws/makefile-fixes/src/web
/net/xanadu/aux0/ws/makefile-fixes/src/gui
/net/xanadu/aux0/ws/makefile-fixes/src/um
/net/xanadu/aux0/ws/makefile-fixes/src/po
/net/xanadu/aux0/ws/makefile-fixes/src/util/misc
/net/xanadu/aux0/ws/makefile-fixes/src/brand
/usr/bin/python setup.py build
running build
running build_py
running build_ext
$
- clobber and clean should work properly:
- clean should delete *all* artifacts of the build that occur
in the source hierarchy (like .o files).
- clobber should depend on clean, and should destroy from the
proto area all components which are placed there by "install"
- Test each target with a clean workspace (i.e. hg clone your
workspace to get a virgin one, and test builds there). Test
install targets by deleting the proto area and rebuilding.
