Hi all this isn’t an actual support request, I’m just trying to get a webcam to work, so if you have important things to do, do those
But I’d appreciate help with the following:
I would like to replace the already by default installed UVC driver with a modified version that I want/need to build from source code.
Why? The webcam doesn’t work because the driver doesn’t recognize it as a cam. It’s a know problem, and there is already a rough “tutorial” about how to fix this on ubuntu, which i have tested on a live ubuntu and it seems to work - i could use the cam there. I don’t have exactly the same cam model, but it’s easy to adapt the patch.
However, the steps and commands of this tutorial won’t work with Rocky, obviously, and I’m at a total loss here.
Tried some things, you know, “learning by doing”, but nothing worked, and it seems pointless to try this myself (I’m a linux newbie, sorry… am probably not using the correct terminology either…).
Here is the shortened tutorial for ubuntu:
Enable source code repositories, then fetch the source code with:
apt-get source linux-modules-extra-$(uname -r)
In the source code folder, navigate to:
Replace the uvcdriver.c file with the patched version.
Open directory in terminal, then:
make -j4 -C /lib/modules/$(uname -r)/build M=$(pwd) modules
sudo cp uvcvideo.ko /lib/modules/$(uname -r)/kernel/drivers/media/usb/uvc/
I already struggle with the rocky source code.
For example, I’ve tried downloading it with
$ dnf download --source kernel (found the command here in the forums) which downloaded a ~135 Mb kernel-…src.rpm , but it seems i can do nothing with it, it won’t install.
I’ve read here that (maybe?) i need the rocky devtools https://docs.rockylinux.org/guides/package_management/developer_start2/, so I’ve downloaded the zip from github, extracted it but “make” won’t work with it and gives an error.
Now, I want to just ask:
What would be even the procedure here?
What (part of the) rocky source do I need, and how to get it?
About the last 2 commands for making the driver, I don’t know if those would generally work.
I noticed however, that on Rocky Linux, unlike ubuntu, the compiled driver is in a compressed .xz file. Don’t know if compressing it would be part of the make process…
Any hint or help is welcome thank you!
