golang-crossbuild

what worked for me for cross-compiling go: https://github.com/elastic/golang-crossbuild docker images for macos and windows (not linux though) https://github.com/rust-cross/rust-musl-cross docker images for linux (yes, it's possible to use the same one for go, you just need to put go binary there) so it's static with musl libc and sure to not have some weird issues with old/new libc on old/new/whatever linuxes (it might be over the top and the zig thing might effectively do the same thing, but I never got it to compile) oh and apple-codesign rust cargo to get through the signing nonsense

Hm, this doesn't match my experience at all, I just use rcodesign (the third party rust tool), some plist and xar magic (that I honestly forgot) and call it a day it's sad that we need third party tool to be able to codesign and notarize effectively (and from other OSes and CIs), but it works now but maybe I miss something that the author needed and I didn't. The hardest part was cross-compiling for macOS but we did it too with these images from elasticsearch https://github.com/elastic/golang-crossbuild
