libcpuid 0.2.1 SlackBuild and packages

In the last week I’ve tried to make my first SlackBuild script. I’ve decided to start with libcpuid.

libcpuid is a small C library for x86 CPU detection and feature extraction.
Using it, you can:

  • get the processor vendor, model, brand string, code name
  • get information about CPU features such as: number of cores or logical CPUs, cache sizes, CPU clock
  • check if the processor implements a specific instruction set such as the SSE2, 3DNow!
  • execute the CPUID and RDTSC instructions (portably!)
  • and have this all in your commercial application, without getting into trouble.

It works on Windows, Linux and Mac OS X, both 32-bit and 64-bit flavours. Compiler support
includes GCC and Microsoft Visual C++ (and compatible, e.g. Intel C++ compiler).

I’ve submitted a .tar.gz to the admin staff of and, after a few days, they have approved it. You can find there all the needed to build your package.

On this site I also provide a modified version of the SlackBuild and the prebuilt packages for x86 and x86_64 architectures. You can find all these files into my “Slackware stuff” section (see on the right).

Just a brief reminder on how to build the package using the SlackBuild script:

Download the .tar.gz containing the SlackBuild script (libcpuid.tar.gz) and the sources (libcpuid-0.2.1.tar.gz in this case).

After having placed the two files in the same directory, open a terminal and place yourself into that directory using the cd command.

Unpack the SlackBuild archive, place the sources into the unpacked folder and enter into that folder:

tar -zxvf libcpuid.tar.gz
mv libcpuid-0.2.1.tar.gz libcpuid
cd libcpuid

Now, give the execution permissions to the script:

chmod +x libcpuid.SlackBuild

Become super user (you must insert the root password) and then launch the script:


At the end of the building procedure you will find your package into the /tmp directory.
Now, to install the package give this command:

installpkg /tmp/libcpuid-*.t?z

This command covers all the possible cases, also depending on which SlackBuild script you use. In particular it takes in account of:

  • target architecture
  • package tag (if any)
  • package version
  • package format (can be .tgz or .txz)

Ok, if all succeeded, libcpuid is now installed on your system!
