run modprobe nct6687 to load the module and then run sensors to get the outputs.

PKGBUILD has been updated for r225.4864fd6. Apologies for the delay folks.

FYI, the maintainer (me) is not inactive. I have just been on vacation. Have a little patience please! I just returned from vacation today, and will review the out-of-date request shortly.

Upstream issue filed:

https://github.com/Fred78290/nct6687d/issues/198

And the upstream dev has nothing to do with this package, which hasn't been touched since before the last time I commented on it, a year ago.

This can not build anymore. During build, I get

Error! Build of nct6687.ko failed for: 7.1.8-1-cachyos (x86_64)
Make sure the name and location of the generated module are correct,
or consult /var/lib/dkms/nct6687d-dkms-git/r225.4864fd6/build/make.log for more information.

and in the log

Just for your information: On the MSI PRO B650M-P motherboard (BIOS 7E27v1H4 (Beta version)), all sensors are recognized and display data correctly, but I don't have control over the fan speed. I'm new to Linux, but if I can do anything to help the project, please get in touch. (Sorry for my translator's English, I only speak and write in Brazilian Portuguese).

seems like the package is missing some declared dependencies? going by the source repo https://github.com/Fred78290/nct6687d?tab=readme-ov-file#dependencies it should depend on "make automake linux-firmware linux-headers dkms base-devel", but it currently only declares "dkms" in its PKGBUILD. I was missing linux-headers just now and ran into a bunch of errors like this:

@kodr: pkgver is always set to the last version that was manually packaged. pkgver() is supposed to return the current version, and building the package updates the PKGBUILD.

I don't know what to tell you if paru doesn't support probing -git packages for version updates without forcing a rebuild.

well, I found out what is the problem.
I use Octopi/Paru to install the package.
The problem is that pkgver is set in PKGBUILD, and it shouldn't be defined to pull the latest changes.
What's happening:

$ paru -S nct6687d-dkms-git

Aur (1)                Ancienne Version  Nouvelle Version  Make Only
aur/nct6687d-dkms-git                    r78.df1565a-2     Non

r78.df1565a-2 isn't the latest version, but what is set in pkgver.
I can't "update" the package unless I remove it and reinstall it.

paru -R nct6687d-dkms-git
paru -Sc nct6687d-dkms-git

my bad, at some point it was pulling an upstream version which wasn't compatible with the current kernel. Thanks for the feedback.

@kodr I don't know what you're talking about. This package builds and loads fine for me. (See below.) Is there some particular error message that you are experiencing?
