Package fails to build. I was told by looking-glass maintainers that in-source builds are not supported and that may be a reason.

You are correct. My bad.

@Netboy3; I'm not pulling/building against master submodules or otherwise diverting those definitions to commits not specified by upstream. Each git repo defines the submodule version/commit being used. That means (at the time of writing) for looking-glass it's using cimgui@83f729b (a.k.a. cimgui 1.82), which in turn uses imgui@64aab84 (1.82 + 2 extra). This isn't functioning any differently from the submodules it had already; PureSpice and LGMP.

Netboy3 commented on 2021-07-20 01:57 (UTC)

Thx for adding the new cimgui/imgui dependency. Only thing you should consider is that the devs are currently building against version 1.82 of cimgui/imgui and you are pulling cimgui master which seems to be quite active and might cause LG builds to break or be inconsistent with the way the LG devs use it.

Dependency on glu was removed. Please see commit: https://github.com/gnif/LookingGlass/commit/2973319bff80bf1531265bdbec6707bdda3f40eb

xiretza commented on 2021-01-20 09:59 (UTC)

Now requires makedepends=('libxss') and depends=('libxss') in package_looking-glass-git(): https://github.com/gnif/LookingGlass/commit/8cb0cbb91d21f501d0c3ac367ba98ece284bd8e3

xiretza commented on 2021-01-17 16:39 (UTC)

requires makedepends=('wayland-protocols').

Hi @Omar007. Now that the MinGW cross-compiler toolchain mingw-w64-gcc and all it's dependencies are available in the community repo, you might want to consider adding building the looking-glass Windows host executable to this package.
