Emacs master on builds with full bootstrap on Windows

Emacs master on builds with full bootstrap on Windows

[Andy Moreton]

HI,

Emacs master fails to build for the last day or so for 64bit mingw64 on
Windows. A full bootstrap succeeds, but any subsequent builds fail with:

Dumping from C:/emacs/git/emacs/master/obj-mingw64-x86_64/src/temacs.exe
          to C:/emacs/git/emacs/master/obj-mingw64-x86_64/src/emacs.exe
mv -f emacs.exe bootstrap-emacs.exe
make -C ../lisp compile-first EMACS="../src/bootstrap-emacs.exe"

git rev-parse master

Running a non-parallel build does not help - only a full bootstrap
succeeds.

Try

make bootstrap-clean
make generate-ldefs-boot

Probably my changes.

This needs "configure" after "make bootstrap-clean", as I do builds
in a subdirectory. "make -j4 generate-ldefs-boot" then fails:

make[2]: Leaving directory '/c/emacs/git/emacs/master/obj-mingw64-x86_64/lisp'
echo Cleaning to enable generate-ldefs-boot

mv ../../lisp/loaddefs.el ../../lisp/ldefs-boot-auto.el
make -C ../../lisp compile-first-delete
make[2]: Entering directory '/c/emacs/git/emacs/master/lisp'
make[2]: *** No rule to make target 'compile-first-delete'.  Stop.
make[2]: Leaving directory '/c/emacs/git/emacs/master/lisp'
make[1]: *** [Makefile:776: generate-ldefs-boot] Error 2

make: *** [Makefile:1191: generate-ldefs-boot] Error 2
mkemacs-mingw64: failed (rc=2): 'make -j4 generate-ldefs-boot'

Repeating this as "make -j1 generate-ldefs-boot" also fails.

The generate-ldefs-boot target needs a minor fix for building outside
the source tree:

diff --git a/src/Makefile.in b/src/Makefile.in
index 730f79801c..1ee31ed51c 100644

        - rm bootstrap-emacs$(EXEEXT)
        - rm emacs$(EXEEXT)

After running "git clean -Xdf" I was able to get a working build, so the
problems I have observed may be transient.
