Enhancement: Document building on Arch

[BenjamenMeyer]

This mainly makes it easy to locally build an Arch image for testing.

Thank you for submitting a pull request and becoming a contributor to Vega Strike's Build System Docker Images.

Please answer the following:

Code Changes:

• This is a documentation change only
• CI Change
• Dev Support Change

Issues:

• n/a

Purpose:

• Give devs the ability to make a docker image supporting Arch for testing purposes to help with triage/build issues on Arch.

1. The Funtoo image is expected to break right now
2. See https://gist.github.com/BenjamenMeyer/fec42f41a610fed910e738fbddc4e671 for how to test this

If you try to test Arch Linux then I do expect you'll see errors. I haven't been able to get that one to work but the dependencies seem to check out - cmake ../engine works; it just fails to compile (gcc errors). The main point of this change is to support testing the CMake configuration.

For a non-Debian distro add the debian tooling, but ensure that the lsb tooling is not installed. For instance with ArchLinux add dpkg to the dependency listing for pacman to install while building the image. This will cause it to detect that dpkg-buildpackage is there but lsb_release is not; previously this would cause it to break on the usage of etc/debian_version; however, with vegastrike/Vega-Strike-Engine-Source#806 and vegastrike/Vega-Strike-Engine-Source#805 it should no longer do so, but list it as an Unknown Debian distro.

IMO you should list the base-devel package which depends on make, automake, gcc, etc see Dependencies list on https://archlinux.org/packages/core/any/base-devel/

vegastrike/Vega-Strike-Engine-Source#801 (comment)

I do, however, run into other issues with Arch.

Need to install gcc12 and use it export CC=/usr/bin/gcc-12 CXX=/usr/bin/g++-12

v0.8.0 also need 2 patches https://aur.archlinux.org/cgit/aur.git/tree/PKGBUILD?h=vegastrike-engine

0.8.x branch need a cmake flag -DCMAKE_CXX_FLAGS="$CXXFLAGS -Wno-error=format-security" \ https://aur.archlinux.org/cgit/aur.git/tree/PKGBUILD?h=vegastrike-engine-release-git

@FabioLolix would you be open to submitting those as PRs?

I'll take a look later too, but PRs are welcome and get merged quickly too.

UPDATE:

• https://raw.githubusercontent.com/FabioLolix/AUR-artifacts/master/vegastrike-delete-include-eval.h.patch - we have eval.h gated based on the Python Version so this should not be required any longer.
• https://raw.githubusercontent.com/FabioLolix/AUR-artifacts/master/vegastrike-std-cerr-fix.patch - this is certainly legit, and I'd love to see you get the credit for it in our history.

yeah, we probably should have the base-devel packages in the listing. That said, while automake/autconf is listed we don't use it any more. I'll update the Arch here to include base-devel.

UPDATE: Unfortunately unlike Gentoo, Arch doesn't support slotting so there is only one version of a tool AFAICT. I added GCC 12 in there too so folks can set CC/CXX to gcc-12/g++-12 for testing. Confirmed my 0.8.x PR with Arch for building it.

No need, you already have those fixes in 0.8.x branch
