Firstly, I don't know how experienced you are with RPM itself. Helps to learn a bit about the package system, you'll have a much easier time of system maintenance. This is the RPM book, and it's all on line: http://www.rpm.org/max-rpm/ Could do a lot worse than learning some of the basics. There's been some changes since it was published, most obviously that the building commands have been split out into a separate rpmbuild command. man rpm/rpmbuild will update you on that. My usual plan goes something like this (replace version as appropriate): (None of this involves being root.) 1. apt-get source mythtv 2. rpm -ivh mythtv-0.16.0.cvs20041220-87.src.rpm 3. cd ~/rpm/SPECS 4. vi mythtv-0.16.0.cvs20041220-87.rhfc3.at.spec (I add '.mje.1' to the Release: field so I know I built it) 4. rpmbuild -ba --without xvmcnvidia --without opengl_vsync mythtv-0.16.0.cvs20041220-87.rhfc3.at.spec (Choose the --with/--without options to suit your setup, see the mythtv-0.16.0.cvs20041220-87.rhfc3.at.spec file for the full list. Then, as root, install the binary package(s) it generates and lists at the end. You'll need a .rpmmacros file which contains something similar to this: %_topdir /home/martin/rpm In addition, you'll need to add the atrpms macros from this post to the same file: http://lists.atrpms.net/pipermail/atrpms-devel/2004-November/000467.html Having practised with rebuilding the version Axel provided you can then go in & update the CVS to a newer version as you wish. Unfortunately Axel doesn't seem to include all the CVS directories so you can't just unpack the archive, cvs update, and then repack it. You should, however, be able to drop a new one in. So get a CVS checkout, tar.bz2 it up, and stick it in ~/rpm/SOURCES. Make sure the tarfile name matches what you put in Version: in the .spec file. If in doubt, unpack the one from the RPM (again, in SOURCES) and make sure yours looks the same. Again, vi the .spec file to update Version:/Release: as appropriate, then rebuild. I recommend you always at least bump the Release: when you rebuild so you don't end up with the confusion of differing packages with the same version number. Also best to add a quick note to the %changelog section for future reference. As to a HOWTO, the best person to write it is the one who's just done it all for the first time and has everything fresh. I'm bound to have forgotten a crucial step somewhere, for which I apologise in advance. ;) So presuming you manage to get somewhere with all this, how about writing it up in a howto & adding it to Jarod's documentation, or the wiki? > I understood wiping out all the mythtv rpms and then > downloading, configuring, compiling and installing the CVS source > code. How does using the CVS RPMs differ from this. Do they basically > download and put the source code somewhere and from that point on it's > the same as normal CVS? The main reason is that the end result is really no different from just installing a new version pre-built for you. This has lots of advantages - eg. easy, clean upgrades and downgrades (don't forget to backup the db). RPM will handle dependencies for you, so it may be possible to run precompiled myth modules against your CVS myth RPMs (depending on how far they've diverged - you can't run 0.16 and cvs together at the moment). But when they do diverge RPM will tell you. No need to try and remove your manual install before upgrading to a new pre-built version. Less breakage because all the files will be installed in the same places in the same way as they always were with the normal RPMs. And other good stuff too. Finally, though, building the RPMs is actually easier. It might seem counter-intuitive, but all of the instructions for configuring, building and installing myth are in the RPM .spec file, so they are always completely repeatable and you can't get them wrong. Your only job is to drop a new source tarball in as and when you want, edit a couple of lines of .spec file to match, and rpmbuild -ba xxx.spec. Hope this helps, Martin.
