Installation of PCI Utilities

Install PCI Utilities by running the following commands:

sed -i 's/null ;/null 2>\&1 ;/' update-pciids.sh &&
make PREFIX=/usr

This package does not come with a test suite.

Now, as the root user:

make PREFIX=/usr install

Some packages require the PCI static library. To install the library and headers, issue the following commands as the root user:

install -v -m 755 -d /usr/include/pci &&
install -v -m 644 lib/libpci.a /usr/lib &&
install -v -m 644 lib/*.h /usr/include/pci

Command Explanations

sed -i 's/null ;/null 2>\&1 ;/' update-pciids.sh: This command suppresses some unneeded screen output from the update-pciids command if you don't have either Lynx, Wget, or Curl installed by redirecting the stderr output of the embedded which command to /dev/null.

Configuring PCI Utilities

The pci.ids data file is constantly being updated. To get a current version of this file, run update-pciids as the root user. This program requires the which-2.19 script or program to find cURL-7.16.3, Wget-1.10.2 or Lynx-2.8.6rel.5 which are used to download the most current file, and then replace the existing file in /usr/share.

You may wish to add an entry to root's (or any other user who has write privilege to /usr/share) crontab to automatically update the pci.ids file periodically.
