Installation of PCI Utils

Install PCI Utils by running the following commands:

make PREFIX=/usr                \
     SHAREDIR=/usr/share/hwdata \
     SHARED=yes

This package does not come with a test suite.

Now, as the root user:

make PREFIX=/usr                \
     SHAREDIR=/usr/share/hwdata \
     SHARED=yes                 \
     install install-lib        &&

chmod -v 755 /usr/lib/libpci.so

Command Explanations

SHARED=yes: This parameter enables building of the shared library instead of the static one.

ZLIB=no: This option prevents compression of the pci.ids file.

Configuring PCI Utils

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-2.21 script or program to find cURL-7.88.1, Lynx-2.8.9rel.1, or Wget-1.21.3 which are used to download the most current file, and then replace the existing file in /usr/share/hwdata.

You should update the /usr/share/hwdata/pci.ids file periodically. If you've installed Fcron-3.2.1 and completed the section on periodic jobs, execute the following commands, as the root user, to create a weekly cron job:

cat > /etc/cron.weekly/update-pciids.sh << "EOF" &&
#!/bin/bash
/usr/sbin/update-pciids
EOF
chmod 754 /etc/cron.weekly/update-pciids.sh
