[lm-sensors] via-cputemp: can't compile it

[lm-sensors] via-cputemp: can't compile it

[singumal]

V3.2.0 sensors-detect told me that my VIA M800 Mini-ITX has a VIA
Nano thermal sensor.  Checked the lm-sensors.org wiki on Devices
as instructed.  For the indicated via-cputemp driver, my CentOS
5.5 kernel is just 2.6.18 so I'd need to make a kernel module;
got the Makefile and via-cputemp.c from the indicated site, but
can't compile it, no instructions, doing "make" in a directory
with those two files, I get a number of errors starting with:

via-cputemp.c: In function âvia_cputemp_probeâ:
via-cputemp.c:106: error: called object âcpu_dataâ is not a function

I already have the matching kernel-devel and kernel-headers
installed in the system.

Please tell me what I am missing in assumptions or environment
setup.


Also, in the main package, I noticed a "make install" grammar
error:

   ***  * As off lm-sensors 3.1.0, ...

Your kernel is simply too old for the via-cputemp driver as it exists
today. You run kernel 2.6.18 and the via-cputemp was added in kernel
2.6.33, that's over 3 years apart.

So you will have to adjust the code yourself, or find someone who is
willing to spend time on this task. But be aware that kernel developers
usually don't work on old versions for free.

Thanks for reporting, I've just fixed it.

Or just get and compile a more recent version, such as 2.6.35, on your system,
and see if it boots. That is what I usually do.
