CPU-X is a Free software that gathers information on CPU, motherboard and more.
CPU-X is similar to CPU-Z (Windows), but CPU-X is designed for GNU/Linux; it can also works on *BSD.
This software is written in C programming language, and built with CMake.
This is a graphical software (GTK is used), but it can be used from a shell by using Ncurses or by dumping data.

Dependencies

Build-only dependencies

These dependencies are needed to manually build CPU-X (e.g you can safely remove them after build):

• CMake (minimum version is 3.0, older aren't supported): needed to build CPU-X
• Pkg-Config/Pkgconf: needed by CMake for libraries detection
• NASM: needed to build Libbandwidth

Build and run dependencies

These dependencies are needed to manually build and run CPU-X (e.g you can't remove a dependency if CPU-X was built with):

• GTK3+ (minimum version is 3.8, version 3.14 or newer recommended): required to run CPU-X in GTK mode; not embedded in portable version (use system shared library)
• Ncurses: required to run CPU-X in NCurses mode; embedded in portable version
• Libcpuid (version 0.2.2 or newer is recommended): required to run CPU-X correctly; embedded in portable version
• Libpci: required to run CPU-X correctly; embedded in portable version
• Procps-ng, provides libsystem (Linux only): required to run CPU-X correctly; embedded in portable version
• Libstatgrab, provides libsystem (replaces Procps-ng for non-Linux OS): required to run CPU-X correctly; embedded in portable version
• Curl: optionnal, needed to check if CPU-X is up-to-date

Download/Install

Download packages

You can download binary packages to easily install CPU-X on your system. A lot of distributions are supported, click on your distro logo and follow instruction:

Note: only recent versions of distributions are supported due to CMake 3.0 is needed to build CPU-X but not available on old distributions. A package can be installed on non-supported versions if dependencies can be satisfied (CMake is a build dependency, not an install dependency).

Manual build

For step-by-step guide, you can see the wiki page (GNU/Linux, *BSD and OS X).
First of all, you need to install CMake (this is only needed for build). GTK headers are needed to compile with GTK support.
You can disable components in CPU-X before build by passing argument -D<var>=0 when running CMake:
-DWITH_GTK=0 will disable support of GUI in GTK3+
-DWITH_NCURSES=0 will disable support of NCurses mode
-DWITH_LIBCPUID=0 will avoid calls to Libcpuid (not recommended)
-DWITH_DMIDECODE=0 will not compile modified Dmidecode code and will avoid calls to Libdmidecode (not recommended)
-DWITH_BANDWIDTH=0 will not compile modified Bandwidth code and will avoid calls to Libbandwidth (not recommended)
-DWITH_LIBPCI=0 will avoid calls to Libpci (not recommended)
-DWITH_LIBSYSTEM=0 will avoid calls to Libprocps/Libstatgrab (not recommended)

• If you want to install CPU-X on your system, do:

mkdir build && cd build
cmake ..
make
make install

By default, CPU-X will be installed in /usr/local. If you want to change it, add option cmake -DCMAKE_INSTALL_PREFIX=<absolute_path> .. on CMake invocation.

• If you want to build a portable binary, do:

mkdir pbuild && cd pbuild
cmake -DPORTABLE_BINARY=1 ..
make

Note: portable binary is accomplished/bin/cpu-x, in directory pbuild. Don't do make install after.You can move this runnable file where you want.

Portable version

CPU-X is available in a portable version (Linux 32/64-bit, FreeBSD 32-bit), like CPU-Z.
Latest release is HERE, all releases are here.
Download file CPU-X_vX.X.X_portable.tar.gz or file CPU-X_vX.X.X_portable_noGTK.tar.gz, extract archive, and you can now run CPU-X portable.
You can put these files on a USB stick for example.

Usage

Start program with root privileges allow to use Dmidecode (Libdmi) and avoid empty labels. Application is put in the desktop menus, in System Tools category: entry CPU-X run CPU-X as regular user, and entry CPU-X (Root) grant root privileges.
Else, you can use command cpu-x, or double-click on cpu-x binary is also possible (if program won't start, check if file has executable bit set).
If GTK and NCurses are supported, you can start CPU-X in NCurses mode by taping in a shell (as root) cpu-x --ncurses.
Use cpu-x --help for other commands and help.

Troubleshooting

• CPU-X won't start: try to do a chmod +x on binary.
• CPU-X still won't start: run it from a shell, and look output.
• Some labels are empty: CPU-X needs root privileges to run fine. If you manually build CPU-X, check dependencies. Or else, if a label is still empty, your hardware isn't recognized by a library.

For bugs, you can attach cpu-x -V and # cpu-x -vd outputs to issue.
