I suspect the answer is that at the end of the bootstrap script, if the
aclocal.m4 file is newer than the config.h.in file we need to touch
the config.h.in file.
Hi Harlan
File 'config.h.in' is generated by autoheader [I assume]. Autoheader
will not touch the time-stamp of 'config.h.in' if the content doesn't
change. This can be annoying, and is the reason Automake generated rule
has a 'touch $@' after autoheader is called
$(srcdir)/config.h.in: $(am__configure_deps)
($(am__cd) $(top_srcdir) && $(AUTOHEADER))
rm -f stamp-h1
touch $@
In my bootstrap script I issue autoreconf with option '--force', so I
don't see this problem. If you think that is too expensive, you could
set environment
variable AUTOHEADER with something like:
AUTOHEADER="autoheader -f" autoreconf -vi
Changing the behaviour of autoheader, I suspect will be met by some
significant resistance.
