There's no policy at all to hide the SRPMS from you. If yumex doesn't
show them to you it is either an unimplemented feature or not
something that fits in with its interface (I've never seen or used
yumex). If you've enabled the source repos you can use yumdownloader
with the --source option to grab SRPMS for packages in the repos
you've got installed.
I believe the last time I was able to successfully rebuild an rpm
from its src.rpm was back in RH7.3, I have never been able to get it
to work since. It seems my system always has something it doesn't
need, or doesn't have something it needs.
If you attempt to rebuild an SRPM and you get failed dependencies, you
can pass the list of them to yum and install them. There's a tool
called yum-builddep that can do this automatically, though I think
it's broken at the moment on FC6 (but that could just be my setup).
A couple of times the rpm version has been updated, but the src.rpm
hadn't been adjusted to match, so the build fails. Generally
speaking, a ./configure sorts that stuff quite well.
If you have the proper development headers and libraries to build the
package, then rpm should see them the same as configure would. Where
differences can occur is where configure may be set to happily ignore
some missing libraries and just disable functionality, the SRPM is set
to require those libraries so that any build will provide the full
functionality. For optional deps, you could edit the specfile and
remove the dependency.
And there needs to be someplace on the net a decent helpfile on
writing the spec file.
The rpmdevtools package provides a script to create a specfile,
fedora-newrpmspec. It will create a basic specfile that's formatted
as the Fedora Extras guidelines suggest. You then just fill in a few
pieces and build away.
There are numerous guides to rpm on the net. A very good guide is the
rpm-guide, on the Fedora Wiki:
Another (also still in draft form) is:
The packaging guidelines for Fedora are here:
Given the state of scripting languages today, there is no excuse
whatsoever for there not being a utility that can take the tarballs
config.status file once ./configure has been run, and extract whats
needed for the spec file from it. That would be the icing on the
cake for checkinstall IMNSHO.
There are far too many broken tarballs out there for that. If you
build software often you'll find that some of it will try to overwrite
files that you don't want it to. If you build as root you won't know
this until it's too late. If you build rpms and do it as a non-root
user you will find this out during the packaging process and then you
you can patch the tarball.
Another reason to use rpm is that you can reliably uninstall it. Not
all tarballs have a properly defined uninstall target in their
Makefiles. So you'll have lots of fun tracking down all the stuff
they may have strewn across your file system when you want to remove
That (the invisibility to rpm's database) is the only disadvantage
I'm aware of. As far as the systems ability to use the program in
question is concerned, I've built far more stable code with
./configure, make, make install as a general rule than I've been
able to see from rpms downloaded and installed as binary packages.
If you're downloading binary rpms that weren't built for the same OS
and version, then you're not likely to get stablity. That won't
surprise anyone that builds packages. Try the same thing with a
tarball. Do a configure && make on FC5 and then tar up the dir. Move
the new tarball to FC6 (or FC4 or Ubuntu or...), untar it and try sudo
make install and see how stable the binary is.
Source code is good for many reasons. :)
Like I said, you pulled my trigger.. Now, how about some URL's I
can print and study so I can build an rpm without running into some
missing includes that aren't findable with yumex or some such?
Check the few above and poke around the links for contributor and
packaging on the FE wiki:
Building an rpm is definitely one more step, but the work pays off
well in my opinion.
