Building custom RPMs

jbeiter · 08-07-2013, 09:24 AM

Can anyone recommend a good resource for learning how to build RPM packages from source tarballs? Redhat doesn't support it and after doing repeated searches for the past 4 days, there is nothing on the internet except for a shallow how-tos.

I'm trying to package a build of clamav we can distribute internally but will eventually need to make builds of java, jboss, tripwire, etc...

Some specific problems I am having include:

- I created a non-root account to build rpms but even though I specified a buildroot, when I build the RPM it still tries to overwrite libs in /var/lib.

- I downloaded the source tarball from clamav.com, can configure;make;make install just fine but when I build the rpm then try to install the rpm on another system it complains that the prereq libclamav.so.6 isn't installed.. but its in the source tarball. Shouldn't rpm include it as part of the make install?

The best doc I've found so far is the max-rpm.pdf document by Ed Bailey. I'm following it but not finding ways around these roadblocks. Looked at LDP too. If anyone knows of better resources, I'd appreciate the clue.

Redhat doesn't support it ..

All Redhat EL* packages are available as {source code + a spec file},
that's the SRC.RPMS :
ftp://ftp.redhat.com/redhat/linux/en...r/en/os/SRPMS/

Clamav as an SRC.RPM for EL6 : http://pkgs.repoforge.org/clamav/
> http://pkgs.repoforge.org/clamav/cla...5-1.rf.src.rpm
> clamav-0.97.5-1.rf.src.rpm

Version 0.97.8 : http://dl.fedoraproject.org/pub/fedo...ource/SRPMS/c/

What does the spec file say ? Is libclamav.so.6 getting installed ?

holy cow that srpm has dozens of unresolved dependancies.. I was able to compile and install the source tarball from clamav.com out of the box.

my spec file is pretty primitive compared to the nightmare included in that source rpm but pretty standard for every document and howto on rpmbuild I've found so far.

guess I'll try to study this fedoraproject spec file if there are no better references for this stuff.

For those of you who can take a source tarball and turn it into an RPM, where did you learn how to do this? What resources did you turn to for questions?

have you seen the command rpmbuild? it can take a tarball and create an rpm.
