When building inside the jdk/make directory, there is a default 'make
all' that populates the
OUTPUTDIR area jdk/build/$(PLATFORM)-$(ARCH) bin, lib, classes, etc.
This is enough to run the jdk, but no rt.jar and no formal images. The
classes from the classes
directory are used directly. If you specified ALT_OUTPUTDIR, then look
The "images" are created by running 'cd jdk/make && make images' which
will show up in
directories j2sdk-image and j2re-image. This logic is mostly in jdk/
However, if you have not done a 'make all', the 'make images' will not
The very top Makefile of the forest uses the jdk/make/Makefile and by
default does both the
'all' and 'images' targets, but also redirects the default output
directory to the top level.
So depending on what directory in the forest you are in, the default
OUTPUTDIR can change,
and the images are never created by the lower level makefiles.
