[gentoo-user] [off-topic] RPM binary on Gentoo

Hi All,

I have an rpm binary which looks like this on a RH 
machine: /usr/src/redhat/RPMS/i386/packageXXX.el5.i386.rpm

How can I use this on a gentoo machine (I understand that it won't be 
maintained by portage).

Use rpm2targz to turn it into a tarball, then unpack it into your
root filesystem (after first checking the contents).

Thanks Neil, is that the equivalent of running:

yum install /usr/src/redhat/RPMS/i386/packageXXX.el5.i386.rpm

on RH?

No.  It is equivalent to running rpm2targz on RH and them extracting the 
tarball to / :P  It is equivalent to extracting *any* tarball to / for 
that matter.

If you're familiar with ebuilds, you can write one that does all this so 
you can do "emerge packageXXX" to install it.

More specifically, it does not run any pre/post-install scripts in the
RPM. There is an rpm package too, but this almost always fails because
the RPM database shows no dependencies installed.

And there's an rpm.eclass to do some of the work for you.

If you also have access to the source rpm, you can create an ebuild
with the help of the above mentioned eclass which just takes care of
the proper unpacking of the rpm source. You will find some information
here [1] or directly in the eclass which is located in your portage
tree in the eclass directory.

Or into the /usr/local hierarchy to keep the stuff separated - who knows 
what this would overwrite. I would even consider using xstow for this:

emerge xstow
rpm2targz packageXXX.el5.i386.rpm
mkdir -p /usr/local/stow/packageXXX
tar -C /usr/local/stow/packageXXX -xf packageXXX.tgz
cd /usr/local/stow
xstow packageXXX

xtow creates symlinks, so /usr/local/stow/packageXXX/bin/foo will also be 
found in /usr/local/bin/foo, and so on. To uninstall, just call xstow -D 
packageXXX from /usr/lcoal/stow, and remove the packageXXX diretory.

Just emerge yum.

No, just don't. How do you expect yum to operate correctly without a gully 
populated rpm database? It will fail (as already said by another poster).

Fact is, a portage system is in no state to deal with an rpm natively. It 
doesn't know what to do with it, doesn't understand how or where to get the 
pre/post install scripts and rpm does not know how to deal with portage file 
collisions.

You are asking a user to run two package managers in parallel, both unaware of 
each other. This is suicide.

Correct way: realize you are trying to do something no package manager is 
built to do. So, you do it manually. Convert the rpm to a tarball, extract it 
and do all install steps manually. It's a good idea to install the binaries to 
/usr/local/ or /opt/ - the correct place to put binaries unknown to a package 
manger (portage won't nuke them there)

Thank you all for your advice.
