Missing infos on CentOS 6.x / RedHat Enterprise Linux 6.x

[GrandAdmiralThrawn]

On older RedHat EL and CentOS systems quite a lot of fields are missing when running CPU-X, even when done as root. Also, there is no GUI support thanks to only a part of GTK3 being present (but that part is fine, the user can rely on the text user interface instead).

Test system:
OS: CentOS 6.x Linux x86_64
CPU: Intel Core i7 980X
Mainboard: ASUS P6T Deluxe V2
GPU: AMD Radeon RX 550 (I think..)

Here's the results when CPU-X is being run as root:

• CPU tab
• Caches tab
• Motherboard tab
• Memory tab
• System tab
• Graphics tab

Details:

• Missing info on the CPU tab, processor part: Vendor, code name, technology, specification, family, model, Ext. family, Ext. model, stepping, instructions.
• Missing info on the CPU tab, cache part: Everything.
• Missing info on the CPU tab, core part: Everything.
• Missing info on the Caches tab: Everything.
• Missing info on the Motherboard tab: Vendor, model.
• Wrongly reported info on the Memory tab: DRAM manufacturer & module part numbers (not provided correctly by dmidecode).
• Missing info on the Memory tab: DRAM latencies. Those would likely require reading model-specific registers (MSRs) though, so probably not easy to do.
• Missing info on the System tab: Distribution. Please see the following error:

grep: /etc/os-release: No such file or directory
CPU-X:util.c:212: an error occurred while running command 'grep PRETTY_NAME= /etc/os-release | awk -F '"|"' '{print $2}'' (fgets)

Note that SYSV init based Linux systems (which don't have systemd) sometimes won't have
/etc/os-release. On Red Hat based systems, a simple pretty name is stored in
/etc/redhat-release, but a better fallback at least for classic Linux systems would maybe be the output of $ lsb_release -d.

• Wrongly reported info on the System tab: Uptime plus the entire memory information.
• Missing info on the Graphics tab: Everything.

Thank you very much!

It looks like libcpuid is not installed.
Can you give the cpu-x -V command output, please?

Thank for the advice about lsb_release, I will do that.

You're right, # cpu-x -V reported no libcpuid being linked in. I checked out and compiled the source code of libcpuid 0.4.1, installed it, created the proper links for your build system to find everything and then reconfigured and recompiled CPU-X.

It's all working now, thank you! :)

Unfortunately, there's no libcpuid in the RHEL6 package repositories, but no matter. Just one more library to compile.

About lsb_release: I'm not sure whether it exists on all modern distributions, but I assume it should, given that it's been a part of the Linux Standard Base specification for a long time now. I just checked, and it's in the latest LSB 5.0 spec as well.
