RPM Package Manager

The RPM Package Manager is a package manager and package format commonly used for Linux distributions. RPM also runs on Darwin. MacPorts is capable of producing RPMs including depencency information.
This page describes how to use RPM on a PureDarwin system.

About RPM


RPM is the package manager and package format used by Red Hat, Novell/SUSE, Mandriva, and other Linux distributions.
It is located at http://rpm.org/ 


RPM5 is a branch of RPM located at rpm5.org.
Although both have common roots, it is not the branch of RPM that is used by Red Hat, for example.
It is located at http://rpm5.org/ 
More about the differences can be found here, for example.


RPM in MacPorts

MacPorts provides ports for RPM. However, there is a chicken-and-egg problem because RPM and its dependencies need to be installed before RPM can be used itself.

port search rpm
apt-rpm                        sysutils/apt-rpm 0.5.15lorg3.93 Automatic updater and package installer/remover for RPM
rpm                            sysutils/rpm   4.4.9        The RPM package management system.
[...]
rpm50                          sysutils/rpm50 5.0.3        The RPM package management system.
rpm51                          sysutils/rpm51 5.1.4        The RPM package management system.

RPM from rpm5.org

The rpm package from rpm5.org is a self-contained bundle that comes with all the dependencies that are not part of Darwin itself.

However, even after it has been installed it says "package rpm is not installed". Bug?

Installing RPM5 on PureDarwin

To install RPM5 on a PureDarwin system, do the following:
  1. Download the dmg from http://rpm5.org/files/rpm/rpm-5.1/BINARY/
  2. Mount the dmg on the Mac, copy RPM5.pkg to the root of the PureDarwin system
  3. On the target system, do: cd / ; gunzip -c RPM5.pkg/Contents/Archive.pax.gz | pax -r
This installs RPM5 to /usr/local/bin/rpm. The RPM database is located at /var/local/lib/rpm/.

Make sure the following depenencies are met on the PureDarwin system:
  • /usr/lib/libbz2.1.0.dylib
  • /usr/lib/libxml2.2.dylib (DarwinBuild project libxml2)
  • /usr/lib/libSystem.B.dylib
  • /usr/lib/libz.1.dylib
  • /usr/lib/libiconv.2.dylib
  • /usr/lib/libssl.0.9.7.dylib (DarwinBuild project OpenSSL)
  • /usr/lib/libcrypto.0.9.7.dylib
  • /usr/lib/libgcc_s.1.dylib

Building RPMs with MacPorts

Follow the instructions on the MacPorts page and use /opt/local/bin/port rpm someproject.
Should you get an error about missing parts, then do /opt/local/bin/port unarchive someproject before.

Useful RPM commands

To run commands on RPMs that are not installed yet, add the p option as shown below.
  • Install a package rpm -ivh --noparentdirs somepackage.rpm
  • Show which packages are installed rpm -qa
  • Show information about an package rpm -qi somepackage or rpm -qpi somepackage.rpm
  • Show which files are in an package rpm -ql somepackage or rpm -qpl somepackage.rpm
  • Show which dependencies a package requires rpm -qR somepackage or rpm -qpR somepackage.rpm
  • Remove an installed package rpm -e somepackage
  • Show help rpm --help

Troubleshooting

org.macports.darwin9 is needed

Problem: Each package fails to install with the message "org.macports.darwin9 is needed".
Solution: Satisfy the dependency to org.macports.darwin9 by installing the RPM below. This is a dummy package that contains no actual software but tells the RPM database about the Darwin base system (specifically, the parts installed from DarwinBuild rather than MacPorts). It is based on http://svn.macports.org/repository/macports/users/afb/macosx-base.spec and was built with rpmbuild -bb macosx-base.spec. (Todo: Check what the OpenDarwin 7 CD did. Deleting that line from portrpm.tcl might also be an option.)

Installation fails due to dependencies on itself

Problem: When trying to install a package, RPM complains that directories are missing that are either part of the base system or should be part of the package that is about to be installed.

bash-3.2# ls /opt/local/
bin/     etc/     include/ lib/     share/   src/     var/ 

bash-3.2# rpm -ivh /libiconv-1.12-0.i386.rpm error: Failed dependencies:
/opt/local/bin is needed by libiconv-1.12-0.i386
/opt/local/include is needed by libiconv-1.12-0.i386
/opt/local/lib is needed by libiconv-1.12-0.i386
/opt/local/share/doc/libiconv-1.12 is needed by libiconv-1.12-0.i386
/opt/local/share/man/man1 is needed by libiconv-1.12-0.i386
/opt/local/share/man/man3 is needed by libiconv-1.12-0.i386

Solution: As a workaround, use rpm -ivh --noparentdirs somepackage.rpm
Sometimes, if you really know what you are doing, --nodeps might also be helpful.
Final solution may be related to this - 
please let us know.

Disk fills up quickly

Problem: When using RPM a lot, the disk fills up quickly.
Solution: By default, RPM5 saves any RPM that you uninstall in /var/local/spool/repackage/.
This can be disabled by changing %repackage_all_erasures to 0 in /usr/local/lib/rpm/macros.

To be investigated

OpenDarwin 6.2.2 had RPMs for the projects in DarwinBuild. How were these made?

sh-3.2# rpm -qip /Volumes/OpenDarwin6.6.2/System/Installation/RPMS/org.opendarwin.misc_cmds-6.6.2-4.fat.rpm
Name        : org.opendarwin.misc_cmds     Relocations: (not relocatable)
Version     : 6.6.2                             Vendor: OpenDarwin
Release     : 4                             Build Date: Sun Jul  6 10:15:26 2003
Install Date: (not installed)               Build Host: lamancha.opendarwin.org
Group       : System                        Source RPM: org.opendarwin.misc_cmds-6.6.2-4.src.rpm
Size        : 490564                           License: ?
Signature   : (none)
Summary     : misc_cmds
Description :
OpenDarwin project misc_cmds

According to #opendarwin, these were built before DarwinBuild was around. A Perl script was used to generate RPM spec files, and the contents od the DSTROOT was packaged up.

A quick and dirty way to unpack a directory of RPMs

UNP=$(find i386/*.rpm)  && for UN in $UNP; do ./opt/local/bin/rpm2cpio  $UN | cpio -i -d -v ; done
