[Pkg-pulseaudio-devel] Bug#576457: config.h regenerated at wrong place for amd64

[Torsten Marek]

Hi,

something is strange in there. If you check the build log, you'll see
that configure is run twice, then config.h.in is regenerated using
autoheader, but config.h is build via config.status only after "make
all-recursive" is executed.

In a local build, config.h is created immediately after config.h.in, and
judging from the rules, there is no way around that:


all: $(BUILT_SOURCES) config.h
        $(MAKE) $(AM_MAKEFLAGS) all-recursive


...

config.h: stamp-h1
        @if test ! -f $@; then \
          rm -f stamp-h1; \
          $(MAKE) $(AM_MAKEFLAGS) stamp-h1; \
        else :; fi

stamp-h1: $(srcdir)/config.h.in $(top_builddir)/config.status
        @rm -f stamp-h1
        cd $(top_builddir) && $(SHELL) ./config.status config.h
$(srcdir)/config.h.in:  $(am__configure_deps) 
        ($(am__cd) $(top_srcdir) && $(AUTOHEADER))
        rm -f stamp-h1
        touch $@

(copy from a local Makefile)

Excerpt from the buildd log:

make[1]: Leaving directory `/build/buildd-pulseaudio_0.9.21-1.2-amd64-2bGIeC/pulseaudio-0.9.21'
make[1]: Entering directory `/build/buildd-pulseaudio_0.9.21-1.2-amd64-2bGIeC/pulseaudio-0.9.21'
echo 0.9.21 > .version-t && mv .version-t .version
(CDPATH="${ZSH_VERSION+.}:" && cd . && /bin/bash /build/buildd-pulseaudio_0.9.21-1.2-amd64-2bGIeC/pulseaudio-0.9.21/missing --run autoheader)
rm -f stamp-h1
touch config.h.in
/usr/bin/make  all-recursive
... many many lines ...
cd . && /bin/bash ./config.status config.h
config.status: creating config.h


Excerpt from local log:

make[1]: Leaving directory `/tmp/buildd/pulseaudio-0.9.21'
make[1]: Entering directory `/tmp/buildd/pulseaudio-0.9.21'
echo 0.9.21 > .version-t && mv .version-t .version
(CDPATH="${ZSH_VERSION+.}:" && cd . && /bin/bash /tmp/buildd/pulseaudio-0.9.21/missing --run autoheader)
rm -f stamp-h1
touch config.h.in
cd . && /bin/bash ./config.status config.h
config.status: creating config.h
/usr/bin/make  all-recursive

I've checked some other architecture's buildd logs, they look exactly like the local one.

best,

Torsten
