Background: Building with the new build system fails with
".../common/shared/Defs-utils.gmk: No such file or directory" in the
build forest, but not in the build-infra forest.
It turned out that a file got missing (!) when we did the integration
from the build-infra forest to the build forest. Defs-utils.gmk was an
empty file, which nevertheless was included by another makefile
(Defs.gmk). Both of these files are part of the copy of the old make
system, which we continuosly remove as we convert more and more to the
new build system. In this case, the contents of Defs-utils.gmk had been
removed, but not the reference to it. The proper cause of action would
of course have been to delete the file and the reference. Since both
files are to be deleted soon anyway, it didn't seem to matter.
... apart from the fact that the webrev patch don't contain new, empty,
files. So Defs-util.gmk got lost when the patch from the build-infra
forest was applied on build forest, even though it was listed on the
webrev index.html page... In my view, this is a bug in the webrev
script, that probably should be looked at.
There are two ways to solve this problem: either we properly create the
Defs-utils.gmk file in the build forest as well, or we remove the
reference to it. The former will just correct the part missing from the
original patch (but that was part of the code reviewed webrev of M1) but
seems a bit silly. The latter feels better but is, actually, a real change.
I created two webrevs for the two solutions:
http://cr.openjdk.java.net/~ihse/defs-util-missing/restore-empty-file.webrev.00/
and
http://cr.openjdk.java.net/~ihse/defs-util-missing/remove-reference.webrev.00/
In any case, I hope we can get this fixed soon since people are starting
to test the new build system now that it's more widely available, and
I'm getting lots of identical bug reports on this one. :-)
