The problem is that there is no dependency in the Makefile telling that
autoconf need to be rerun when the version has changed. Automake has the
variable 'CONFIGURE_DEPENDENCIES' for this purpose, so adding
CONFIGURE_DEPENDENCIES = ChangeLog
would solve the issue but will cause a rerun of autoconf every time you touch
ChangeLog. Rather you want a stamp file, whose timestamp only changes when
the output of 'version.sh packageversion' changes. Something along the lines:
$(srcdir)/.version: ChangeLog
cd $(srcdir) && ./version packageversion > .version-tmp && move-if-change
.version-tmp .version
EXTRA_DIST = $(srcdir)/.version
I don't see any way without a specific file holding the timestamp on when the
version was last updated.
This is very helpful advice (and adds to valuable advice offered in
private emails by others). I don't really like hidden files but I do
have a version.h header file which could already be used for this
purpose. The version.h header file is currently produced from
version.h.in using config.status and it gets copied to the source
directory (if necessary) if the file has changed.
