Guix builds happen in a container which does not have access to the network. Thus, you do have a DNS issues, but it's not one you can resolve within a Guix package build. Looking at the Ghostty documentation, their main build is with Nix, which has the same network restriction, so that's a good sign that this can be made to work. Looking at their PACKAGING.md[1], it says that the only step which requires an internet connection is running this command: --8<---------------cut here---------------start------------->8--- ./nix/build-support/fetch-zig-cache.sh --8<---------------cut here---------------end--------------->8--- Looking in that script[2], it basically just runs "zig build --fetch", with some extra work to fetch some other dependencies. I'm not familiar with Zig builds, but looking at build.zig.zon[3] it seems to list the required dependencies. To get a Guix package building you may need to package these dependencies, and then provide them as inputs to your Ghostty package. I'm not sure whether the Zig build system is set up to handle this properly. I couldn't find any examples of Zig packages with Zig dependencies, but I didn't try very hard.
