I was wondering if there was already a well-considered way to add rpm

Here's my root-level Makefile.am:
------
EXTRA_DIST = arf.spec schema win32 doxygen examples
SUBDIRS = src test
dist-hook:
rm -rf `find $(distdir) -name .svn`
.PHONY: rpmdir srcrpm rpms
rpmdir:
-mkdir -p rpm/BUILD rpm/RPMS rpm/SOURCES rpm/SPECS rpm/SRPMS
Unless you *really* want the clutter of
{BUILD,RPMS,SOURCES,SPECS,SRPMS}, you
might want to think about configuring rpmbuild to put all the build
elements into one
sub-directory.
See ftp://wraptastic.org/pub/jbj/{xrpm,rpmrc,macros} for an explicit
example.
My build cycle looks like
xrpm -ivh foo*.src.rpm
cd /X/foo
xrpm -ba foo.spec
xrpm -Uvh foo*.i386.rpm
cd ..
rm -rf foo
which is probably far simpler to write and maintain as Makefile rules.
xrpm is just a stupid wrapper to invoke
rpmbuild --rcfile /X/rpmrc ...
in order to bring in the per-package-directory build configuration.
srcrpm: dist-bzip2 rpmdir
rpmbuild -ts --define='_topdir $(PWD)/rpm' $(distdir).tar.bz2
rpms: dist-bzip2 rpmdir
rpmbuild -ta --define='_topdir $(PWD)/rpm'
--buildroot=$(PWD)/rpm/tmp $(distdir).tar.bz2

I was also wondering if there was a good way to automate revision
changes in spec files, makefiles, etc. I use subversion for my
repository, and it occurs to me that a good way to tell if I even
need a
build is to compare the root-level "svn info" Revision: tag with the
last time I built. -- Revisions the same? No need to build again! --
There's a number of ways to automate the revision, depending on
what you wish to achieve.
For starters, there is a CvsID: tag in spec files (in rpm-4.4.7, I
fergit when added),
that will permit tracking what CVS revision was used for then build.
IIRC, there is
SvnID: as well, an alias for the same header tag.
There's certainly no reason why the Release: tag cannot be used to
carry the
repository identifier. One would have to insure that the repository
identifier
preserved upgradeability.
Automating is probably achieved most simply by modifying a spec file
template
using sed or m4 before building. Not hard at all with Makefile rules
and file
timestamp dependencies.
