goreleaser integration?

[jkroepke]

Existings projects using goreleaser to distribute go projects. It would be great, if there is a documentation how goreleaser can interact with solod.

And do you know any compatibility issues, if zig cc is used an compiler?

Goreleaser doesn't work with Solod, unfortunately. If we're talking about binary distribution, there are no tools for that right now.

As for zig cc cross-compilation, it does work. Just set the environment variables and you should be all set:

CC='zig cc' CFLAGS='--target=x86-linux-musl' so build -o main .
docker run --rm -v .:/app alpine:latest /app/main

As for zig cc cross-compilation, it does work. Just set the environment variables and you should be all set:

Note: It works with main, but not with stable 0.3 (so build: C compiler: exec: "zig cc": executable file not found in $PATH).

I did a quick test with

# yaml-language-server: $schema=https://goreleaser.com/static/schema.json

version: 2

builds:
  - main: .
    tool: so
    goos:
      - linux
    ldflags: [] # not supported

result into an error:

If so build supports at least -ldflags, it could work. ldflags is manatory, because it can't be disabled in goreleaser. goreleaser/goreleaser#1255

With an shell wrapper that omits -ldflags, plus env templating, here an working example:

# $schema: https://goreleaser.com/static/schema.json

version: 2

builds:
  - main: .
    tool: ./hack/so-goreleaser # shell wrapper
    goos:
      - linux
      - darwin
      - freebsd
    goarch:
      - amd64
      - arm64
    env:
      - CC=zig cc

      - >-
        CFLAGS=
        {{- if eq .Arch "amd64" -}}
          --target=x86_64
        {{- else if eq .Arch "arm64" -}}
          --target=aarch64
        {{- end -}}
        {{- if eq .Os "linux" -}}
          -linux-musl
        {{- else if eq .Os "darwin" -}}
          -macos
        {{- else if eq .Os "freebsd" -}}
          -freebsd
        {{- end }}

      - >-
        LDFLAGS=
        {{- if eq .Os "linux" -}}
          -static
        {{- end }}

results into

Interesting! Thanks a lot. I'll see if I can get so to work well with goreleaser in the next version (v0.5). The current version (v0.4) is feature-frozen now.
