For reasons that are not clear to me, the compilation of honggfuzz has the flag -D_HF_ARCH_LINUX that should not be there (as there is a select in honggfuzz.BUILD). Not sure why this is happening.

Steps to Reproduce the Problem

1. From a Mac, run bazel build //...

I'm leaning to think that there is an issue with Bazel.

If I change to use bazel 6.5.0, then

% git diff
diff --git a/.bazelversion b/.bazelversion
index a8907c0..f22d756 100644

Forcing to use bazel 7.0.0, then the same error shows up.

Bazelisk has a --bisect flag that automatically finds the breaking Bazel commit. Could you run that?

[lgalfaso]

OMG this was painful. Executed

BAZELISK_SHUTDOWN=True BAZELISK_CLEAN=True bazel --bisect=ba3e0cc691fc758ff9510271b962685fcaf14691..7.0.0 build "@honggfuzz//:honggfuzz_engine"

(yes, started with ba3e0cc691fc758ff9510271b962685fcaf14691 as bazel was somehow broken in many releases in between and had to do a scripted bisect using some other script to find a good build).

It shows that

first bad commit is bazelbuild/bazel@30d033c

This is, looks like this is related to bzlmod :(

To double check this, executed

bazel build --noenable_bzlmod "@honggfuzz//:honggfuzz_engine"

and it build without errors.

Not sure how to move forward, as I ended in this rabbit hole when trying to use rules_fuzzing as a dependency from Bazel Repository Central.

Side note, bazelisk is a good tool, but a little more flexibility, it would be amazing. eg

• Do something when a version from bazel is not available (ie, do not fail with the error "could not run Bazel: could not download Bazel: failed to download bazel: failed to download bazel: HTTP GET https://storage.googleapis.com/bazel-builds/artifacts/macos/1da8a825c0fba882f33ea6998a76ff8265fcd32c/bazel failed with error 404", just pick a few version up or down and keep on trying to reduce the range)
• Ask whether the result is good
