find: -printf: unknown primary or operator on macOS

[Strum355]

Describe the bug
Skyscope uses flags for find that are non-existant on the BSD version of find, only on GNU version

To Reproduce

Append to WORKSPACE:

http_archive(
    name = "skyscope",
    sha256 = "2acf7b7f5bf3e66b83e1fac3aa6bcf71d173433ca6786f83d62fb5e9241fe7dc",
    urls = ["https://github.com/tweag/skyscope/releases/download/v0.2.6/skyscope.zip"],
)

load("@skyscope//:repository.bzl", "configure_skyscope")

configure_skyscope()

Run bazel shutdown && bazel build //cmd/gitserver && bazel run -- @skyscope//:import

Expected behavior
Works on both macOS and linux

Environment

• OS name + version: macOS 13.3 with bazel 6.1.1
• Version of the code: 0.2.6

Looks like the MacOS system I tested on has GNU findutils installed, so I missed this issue 🤦‍♂️. Thanks for reporting it @Strum355, I'll report back when I have a fix ready.

This should be fixed in the latest v0.2.7 release:

load("@bazel_tools//tools/build_defs/repo:http.bzl", "http_archive")
http_archive(
    name = "skyscope",
    sha256 = "5544313ec77adbc96856c4cdfb3dfc6b5409e05790860ae19c7d321fb585490b",
    urls = ["https://github.com/tweag/skyscope/releases/download/v0.2.7/skyscope.zip"]
)
load("@skyscope//:repository.bzl", "configure_skyscope")
configure_skyscope()

I'll leave this issue open for the moment. Let me know if you encounter further problems.

Since the change to distribute Skyscope on Linux as a single statically linked binary, there is no longer a wrapper script that calls find, so this issue is resolved (though to use Skyscope on MacOS now, you'll have to build it from source).
