 Diamond (it/she) | i've done it before | 20:48:41 |
 jrick | pie without cgo doesn't really work. static pie is a thing, but go doesn't produce those | 20:50:31 |
| jrick | well it can, but i haven't tried to cross compile them | 20:50:58 |
| jrick | err, i have tried, and failed lol | 20:51:54 |
 kdn | yeah, CGO_ENABLED=0 go build works fine on NixOS | 20:52:15 |
| Diamond (it/she) | yeah for the explicit purpose of cross-building i wouldn't bother with PIE | 20:55:57 |
| Diamond (it/she) | or i guess just build a Nix OCI container instead | 20:56:14 |
| jrick | the issue with building static pie executables is that you need the target platform's ld.so and essentially embed it into the final binary | 20:57:05 |
| jrick | it works if you have the file and can set the appropriate go flags to link with it | 20:57:45 |
| jrick | but makes cross compiling a nightmare | 20:57:49 |
| kdn | I'd love to, but the team uses goreleaser to build for few-teen targets including different architectures, containers & operating systems | 20:58:28 |
| Diamond (it/she) | hm ic | 21:00:36 |
| kdn | I just wanted to adjust my local build to whatever they're running so I can make a proper entrypoint | 21:01:08 |
| Diamond (it/she) | i mean in terms of building containers for usage, whether it's Nix-built or FROM alpine Dockerfile-built doesn't matter too much | 21:02:58 |
| Diamond (it/she) | i mean the whole point of OCI containers is that it has that level of portability | 21:03:06 |
| Diamond (it/she) | i was gonna say if this tool is just dragged into the container as a build step then you can definitely have it build an image and use that in Dockerfile i think? | 21:03:40 |
| Diamond (it/she) | but idrk what you're doing | 21:03:47 |
| kdn | I've no clue either how the whole thing is set up, my guess is that the binary artifact is somewhat carried over from previous steps in the CI/GoReleaser | 21:05:55 |

| xgwq | Hi, I currrently try to package a go package that fetches the version from Buildinfo like this
func GetVersion() (ret string) {
if b, ok := debug.ReadBuildInfo(); ok && len(b.Main.Version) > 0 {
ret = b.Main.Version
} else {
ret = "unknown"
}
return
}
Building that with nix gets (devel) as version, how can I set the version to the real package version?
| 18:12:15 |
| Diamond (it/she) | you could look into fetchgit with preserving .git | 22:14:48 |
