Thank you very much for the quick response.

I just rebuilt cbang and see there is an issue with the latest version of v8 that I need to sort out. I'm guessing it was introduced when v8 went from 12 to 13. I know 12.7.171 worked. You can check out that version of the v8-r PKGBUILD and rebuild if you want to get up and running while I sort it out. You will need to remove the newer version and make sure yay isn't using it.

v8-r 13.1.137-1 , cbang 1.8.0-4
In another attempt, I first built cband and V8-R, I had the same error installing with makepkg.

I don't use yay, so I don't know all that happens when you type that command. The error message you are getting is because when cbang was built, it did not find the v8 installation. Did yay build v8-r before building cbang? Or did you already have a version of v8-r installed? That is why I wanted to know what version of v8-r you are using. I will try to rebuild everything tonight using standard makepkg method and see if there is an issue with the latest v8 and cbang.

cbang 1.8.0-4 from AUR
https://aur.archlinux.org/packages/cbang
That it installs when camotics compiling

yay -S camotics

cbang needs to be built with V8 support. This appears to be a cbang issue and not a camotics issue. It could be changes in V8 are making it so cbang doesn't find it (v8). What is the version of V8-r that you are using when you build cbang?

compile error
Exception: Chakra or V8 support is required, please rebuild C! You may need to set CHAKRA_CORE_HOME or V8_HOME.:

I'll look into it. Have you tried building it yourself? If so, any issues with the build? You can also use the camotics-git package if you want the latest.

There is a newer v1.2.2-rc1 version since 28 July 2021. A "release candidate" should in general be quite robust.

It already includes the scons 4.3 and Python 3 patches, among many others.

So you might consider updating to it, or even adding on top of that the newer commits from master, which contain some additional fixes.
