Ubuntu 18 about lg4l

[CMoH]

You need to be root when installing the kernel module: sudo make install. Try this first

[HansHM]

I did that too, and thought the error whas the same. When i do that the SSL errors stays

and when i do a modprobe hid-g110
modprobe: FATAL: Module hid-g110 not found in directory /lib/modules/4.15.0-43-generic
i got the next error.

[CMoH]

This might be related to secure boot, and the way Ubuntu chose to configure it during their kernel build. Check out this discussion here: andikleen/simple-pt#8

Here's where the modules are on my machine - see if you have something there too:

ls /lib/modules/4.14.83-gentoo/extra/
hid-g110.ko  hid-g13.ko  hid-g15.ko  hid-g19.ko  hid-gcore.ko  hid-gfb.ko

[HansHM]

Oke i did the steps again from the link. The first time is misses something.

Still there is a error:
modprobe hid-g110 or sudo modprobe hid-g110
modprobe: FATAL: Module hid-g110 not found in directory /lib/modules/4.15.0-43-generic

[CMoH]

Try sudo modprobe hid-generic

[CMoH]

Files in /sys are created by kernel code, such as drivers etc so you cannot create new folders there. Some existing files can be written to though, since they represent changeable settings inside the kernel/driver.

Hello CMoH,

I needed to re install Ubuntu en now i stuck whit a new error messages that i din't have before:

A sugestion whas made add askUbuntu to add EXTRA_CFLAGS += $(CFLAGS_EXTRA) -fno-pie add the MakeFile, but it is not there.

[CMoH]

To be honest, one of the reasons I am not using Ubuntu is the fact that I don't have to deal with this kind of problems :)

In a working scenario you'd build the kernel from sources using a particular compiler (gcc) version, and build this external module using that result. This ensures everything matches (linux headers, kernel binaries, the gcc version and settings, such as PIC/PIE settings, etc).

However, with Ubuntu one has to trust that they maintain a perfect match between their binary packages (kernel) and the packages providing us with a kernel build environment (linux headers, linux build config in /lib/modules, gcc etc). Your error seems to point to such a mismatch. But I don't really know.

Do you get the same error if you follow this guide? https://www.cyberciti.biz/tips/build-linux-kernel-module-against-installed-kernel-source-tree.html

It looks like a gcc thing. I can't rememeber installed before and it is not on the VMbox when i do gcc --version. When i remove it i got afther make
/bin/sh: 1: gcc: not found

I have installed apt-get install build-essential

[HansHM]

I did some massif reading about the issue and did some test. Even installed gcc 4.8 but that trows other errors.

Is this a solution? http://mattfife.com/?p=3199 and if yes how do i apply the patch.

[CMoH]

Linux headers usually "match" the kernel, but only the major/minor versions (i.e. 1.14 matches all 1.14.x kernels).

Patch files (or diff files) are not that much. Basically if the first character on a line is a + sign, then this line needs to be added. If it's a - sign, that line needs to be removed.

So you can simply copy/paste the lines starting with the + (such as +KBUILD_CFLAGS += $(call cc-option, -fno-pie)) and next remove the plus signs at the beginning. Place those lines just below the # kbuild part comment in the makefile, and tell me how it goes.

Actually, the end result should look like this:

KBUILD_CFLAGS += $(call cc-option, -fno-pie)
KBUILD_CFLAGS += $(call cc-option, -no-pie)
KBUILD_AFLAGS += $(call cc-option, -fno-pie)
KBUILD_CPPFLAGS += $(call cc-option, -fno-pie)

How can two installations so different.

[CMoH]

Try to replace KBUILD_CFLAGS += (and similar) with EXTRA_CFLAGS +=, or maybe with EXTRA_CFLAGS = (instead of +=)

[HansHM]

EXTRA_CFLAGS = $(call cc-option, -fno-pie)
EXTRA_CFLAGS = $(call cc-option, -no-pie)
KBUILD_AFLAGS = $(call cc-option, -fno-pie)
KBUILD_CPPFLAGS := $(call cc-option, -fno-pie)

Oke, a made a new fresh install (again :))
Before the git clone I installed from the instructions here: https://smallbusiness.chron.com/compile-modules-ubuntu-52622.html
Now i have kernel 4.15.0.29 and before 4.15.0.34 so i was hoping that it worked. Wrong same errors.

[HansHM]

CMoD,

I am totally sorry man. Is mis read your line: To be honest, one of the reasons I am not using Ubuntu is the fact that I don't have to deal with this kind of problems :)

I was sticking to Ubuntu because i thought you wrote it was good.

I am well-known whit Centos, my internet server is running on it. I choses for my home computer Ubuntu because my raspberry.

Whats you advice?

[CMoH]

Heh - sorry about that. I am using Gentoo, where the kernel is configured and built by me. I think Arch also has good support for developers.

Well, I would try to build it using Ubuntu's kernel dev manual: i.e. make it into a deb using their kernel build tools, and install the deb. Maybe even distribute it for other Ubuntu users. Ubuntu's developer docs seem quite in disarray, but perhaps you'll have a better luck than me to find docs on how their kernel maintainers build external modules (e.g. nvidia drivers).

[wangmice]

download the source of ubuntu, there is a fold named certs ,copy the files to the /usr/src/linux-headers-uname -r/certs

[HansHM]

Hallo CMoH,

I try Centos 7 now. I got this error:

[CMoH]

Wow - kernel 3.10.0 is quite old. However, this hiddev API change seems to match a change from kernel 4.11 to 4.12, so maybe you'll get it working by checking out the git branch kernel-4.11

[HansHM]

I removed the ->minor and got
/home/hmobron/lg4l/hid-gcore.c:226:2: warning: return makes integer from pointer without a cast [enabled by default]
return ((struct hiddev *)hdev->hiddev);

But the compiling wend on. Make install worked and i think modeprobe hid-g110 to. And ./rebind worked to.

How can i programm the g keys?

[CMoH]

I don't think your changes are correct. That minor is used to generate the led device name, so you might get a weird name. Have you tried git checkout kernel-4.11 and make ?

There are some userspace tools here, which is the continuation of an abandoned project. You'll find more docs in the latter, and a newer version in the former page.

[CMoH]

By the way, have you seen the piper/ratbag projects?

[HansHM]

I have done that: git checkout kernel-4.11 and make and it worked.
Now working on add macro's to the key. The gnome15 seems not the place for Centos and i use a keyboard the g110.

[HansHM]

Hello CMoH,

I now can load the modules under Centos and Mint. Only Mint i need to run sudo depmod
to let modprobe to find the new modules. Thats great.

I only can't find a way to assign for example key G5 = ctrl+C or G6 = ctrl+c

[CMoH]

This is not implemented in the kernel module, but there are some people contributing to gnome15. Try addressing this on that project. Maybe it's easy to add support in the GUI for G110 and/or for Centos.

[HansHM]

Thank you very much for you help.
