@Torxed: It looks like you're for some reason building with a custom build environment instead of making a clean build. In this case, it's seems you're building with a 10.1 version of GDB living in your home directory? Please build in an up-to-date Arch environment (and preferably a clean one, e.g. use a chroot or something), otherwise you're on your own.

Used yay, but I doubt that's the issue.

I get this error when running makepkg:

==> Starting build()...

Yea for a full repo distributed package it should probably be v1.0 or something. That is sort-of what I expected with the 'wait on the next release'. Though that can also still be a beta I suppose, but time will tell.

If you're just using the PKGBUILD without cloning the AUR repo it should be OK. I'll update this later today to add the build version fix and cover that issue though.

EDIT: Done

The reason is that the logic in version.cmake checks for the existence of a git repo and will then assume it's the LG git repo but it's actually the AUR git repo itself and that will then lead to a wrong version being reported. I told upstream about this and they produced this patch: https://github.com/gnif/LookingGlass/commit/6c545806abc5441be994a1f9315cfd75d4b89682

You should try applying that patch to make sure that upstream error reports carry the right version information.

I just talked to the developer and we'll keep it in AUR for the time being as per upstream wishes. One thing he mentioned is that the current version reported by this very package is wrong. I was able to reproduce the problem.

It should say:

186391981783 [I] main.c:2282 | main | Looking Glass (B3-0-g2973319bff)

what it does say is:

187133868380 [I] main.c:2282 | main | Looking Glass (a5194b94ac)

From what I understand gnif does not wish the community to package looking-glass yet

https://github.com/gnif/LookingGlass/issues/168

Considering the GPL license shall we have this double checked?

@Svenstaro: I have no problem with that. Would appreciate it if you could let me know if you end up ever dropping it (back to the AUR) though, I have no problem resuming work on it if/when that happens.
