Overview

This procedure shows how to...

• Query the OS to see if the packages are installed
• Find missing packages
• Install packages

This example uses Red Hat Enterprise Linux (RHEL) on a PowerPC 64-bit hardware platform and assumes that RHEL requires both 32-bit and 64-bit versions of package...

compat-libstdc++-33-3.2.3-47.3

 

Procedure

1. Query the OS to determine if the packages are already installed.

   rpm -qa | grep compat-libstdc++-33-3.2.3-

   In this example, the OS did not find any matching packages so a blank line is displayed.

   You can also search without the grep argument to see an explicit message about the file:

   rpm -q compat-libstdc++-33-3.2.3-

   The OS returns the following message:

   package compat-libstdc++-33-3.2.3- is not installed

2. Find all related packages on the OS media to get the fully qualified locations.

   This example assumes that the OS media is a compact disc mounted at /media/cdrom. Your CD-ROM device might be at a different location, such as /media/cdrecorder, for example.

   find /media/cdrom -name compat-libstdc++-33-3.2.3-*

   In this example, the OS finds two matching package names. One package is the 32-bit version and the other is the 64-bit version.

   /media/cdrom/RedHat/RPMS/compat-libstdc++-33-3.2.3-47.3.ppc.rpm
   /media/cdrom/RedHat/RPMS/compat-libstdc++-33-3.2.3-47.3.ppc64.rpm

3. Install the first missing package:

   rpm -ivh /media/cdrom/RedHat/RPMS/compat-libstdc++-33-3.2.3-47.3.ppc.rpm

4. Install the second missing package:

   rpm -ivh /media/cdrom/RedHat/RPMS/compat-libstdc++-33-3.2.3-47.3.ppc64.rpm

Alternate method

• Find the packages and verify that the following command installs only the packages that you intend to install.

  find /media/cdrom -name compat-libstdc++-33-3.2.3-* | xargs rpm -ivh

• Installs both packages....

  find /media/cdrom -name compat-libstdc++-33-3.2.3-* | xargs rpm -Uvh

  Install a package when the package is not installed. This command updates a package to a newer version when the package is installed.
