42 Rebuilding Packages
Determining Whether Your Package Is Supported
Rebuilding a supported kernel does not require any prerequisites. In this case,
the standard DUP is used and the rebuild process completes successfully.
Rebuilding an unsupported kernel requires prerequisites. See "Prerequisites
for the Test System."
DUP execute on a given target system and can determine if the running
kernel is supported by the package you are trying to apply to your system.
In cases where the currently running kernel is not supported, the DUP
application tries to rebuild the package. If the prerequisites are not present
for an unsupported kernel, the rebuild fails and the DUP application issues
one of the following error messages:
Update Package is unable to build a device driver for
the running kernel because the required kernel source
files are not installed. See "Rebuilding Packages" in
the Update Packages User’s Guide for more information.
or
Update Package does not support the running kernel.
See "Rebuilding Packages" in the Update Packages
User’s Guide for more information.
The above messages indicate that the running kernel is not supported by the
DUP that you attempted to apply to your Dell system. You can proceed with
the update in one of the following ways:
• Install the prerequisites for compiling customized packages for the running
kernel directly on the system to which the package is being applied, rebuild
the package on the system, and then reapply the rebuilt package.
• Rebuild the package on a test system that meets the prerequisites for a test
system, and then distribute the update to systems that have the same
running kernel, model name, and configuration, across the network.
