The package is now also hosted on archlinuxcn, where you can download binaries especially when you have trouble building them.

A patch is backported to fix dkms failure on 6.10 kernel.

@ivevix Looks like it builds correctly when running cmake/make manually on the host project. However the failure comes from the CFLAGS in /etc/makepkg.conf. I tested by adding:

options=(!buildflags)

to the PKGBUILD and it built properly with makepkg -sri.

I guess that can be used as a workaround as well.

And if you want to keep your CFLAGS (recommended) and just remove the host package, you can use this patch to the PKGBUILD file. Which is what I did since I do not need the host.

nohost.patch:

Apply it with patch PKGBUILD < nohost.patch and then run makepkg as normal.

Can confirm dkms now compiles on 6.10 kernel.

Thank you for quick response ..!!

I mean I can't install looking-glass-rc without it also pulling in looking-glass-rc-host can I?

ixevix commented on 2024-05-18 11:47 (UTC)

Because it doesn't build. Or fix the build. I'm getting the following

@ixevix what do you mean by "remove the -host dependency"? iirc nothing depends on it. It should be ok to use official binary for looking-glass-host binary together with the other packges here.

This pkgbuild is basically a port of aur/looking-glass, which is not a -bin packge. Also build instructions for -host are still available on B7-rc1's documentation. If no additional problem is introduced i'd prefer let it be.

ixevix commented on 2024-05-18 08:21 (UTC)

Would it be possible to remove the -host dependency as building it is not supported upstream? Folks on the looking-glass Discord server are running into issues building it.

ston commented on 2022-11-14 12:26 (UTC)

Dear aur users, I'm sorry, but I'm no longer using archlinux and need someone to help maintain this pkgbuild, I'll drop this package.
