Error in label: label() got unexpected keyword argument 'single_file' with bazel 7.1.1

[JordanPhilipSmith]

I am using bazel 7.1.1. I am trying to use an external repo for GMP (GNU multiprecision) with bazel. I cloned this repo:

cd ~/dev
git clone https://github.com/robin-thomas/bazelify-gmp.git

When I try to compile it, I get an error with M4:

cd ~/dev/bazelify-gmp; bazel test //gmp_6_1_2/... --sandbox_debug --verbose_failures
Computing main repo mapping:
ERROR: Traceback (most recent call last):

"template": attr.label(
Error in label: label() got unexpected keyword argument 'single_file'
ERROR: Error computing the main repository mapping: initialization of module 'm4.bzl' failed

Thank you for your help,
Jordan

That repo is depending on an extremely old (and untagged) version of rules_m4. From https://github.com/robin-thomas/bazelify-gmp/blob/master/WORKSPACE:

git_repository(
    name = "io_bazel_rules_m4",
    remote = "https://github.com/jmillikin/rules_m4",
    commit = "2bf69df77dfb6b3ba6b7fc95c304b0dc279375bc",
)

Please try updating the dependency to one of the released versions of rules_m4.
