Installation of PCI Utils

32-bit Installation

Install PCI Utils by running the following commands: 

make PREFIX=/usr              \
     LIBDIR=/usr/lib32        \
     SHAREDIR=/usr/share/misc \
     SHARED=yes               \
     CC="gcc -m32"

This package does not come with a test suite.

Now, as the root user: 

make PREFIX=/usr              \
     LIBDIR=/usr/lib32        \
     SHAREDIR=/usr/share/misc \
     SHARED=yes               \
     install install-lib      &&

chmod -v 755 /usr/lib32/libpci.so

Clean up the build directory before moving on to the next platform: 

make clean

x32 ABI Installation

Install PCI Utils by running the following commands: 

make PREFIX=/usr              \
     LIBDIR=/usr/libx32       \
     SHAREDIR=/usr/share/misc \
     SHARED=yes               \
     CC="gcc -mx32"

This package does not come with a test suite.

Now, as the root user: 

make PREFIX=/usr              \
     LIBDIR=/usr/libx32       \
     SHAREDIR=/usr/share/misc \
     SHARED=yes               \
     install install-lib      &&

chmod -v 755 /usr/libx32/libpci.so

Clean up the build directory before moving on to the next platform: 

make clean

64-bit Installation

Install PCI Utils by running the following commands: 

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

This package does not come with a test suite.

Now, as the root user: 

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

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

Command Explanations

SHARED=yes: This parameter enables building of shared library instead of 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-2.20 script or program to find cURL-7.40.0, Lynx-2.8.8rel.2 or Wget-1.16.1 which are used to download the most current file, and then replace the existing file in /usr/share/misc.

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