What's the simplest, easiest way to reproduce this bug? Please provide a minimal example if possible.

No response

Which operating system are you running Bazel on?

ubuntu 18.04 lts

What is the output of bazel info release?

No response

If bazel info release returns development version or (@non-git), tell us how you built Bazel.

bazel 0.24.1

What's the output of git remote get-url origin; git rev-parse master; git rev-parse HEAD ?

No response

Any other information, logs, or outputs that you want to share?

I use WSL, and reinstall the system today.

Just before I reinstall the system, it worked for me for many years.

Then, just after I reinstall the system today, it didn't work for me.

I think maybe perviously, when I compiled the program with bazel, it had zlib-1.2.11 on the website, so it could compile it without any problem. The latest time may be March 2022. Even after they deleted zlib-1.2.11, since I have already compiled it on my system, it would not generate a problem.

Then today I reinstalll the system, and it has no zlib in it, then it generates such problem.

Even I download zlib-1.2.12 manually and installed it by myself, the bazel still generates an error.

So I think possible solutions are:

1.update zlib-1.2.11 to zlib-1.2.12 in all the bazel related stuff
2.provide a method for us to specify bazel to download zlib-1.2.12 directly;
3.If we download zlib-1.2.12 and install it, bazel can detect it and would not download it again.

Thank you very much.

After a few hours, now I have solved it.

in ~/.cache/bazel/_bazel_ubuntu/eb9xxxxxxxxxxxxxx/external/com_google_protobuf/

there is a file protobuf_deps.bzl, and I can change the 1.2.11 to 1.2.12, as well as the sha256 field.
def protobuf_deps():
"""Loads common dependencies needed to compile the protobuf library."""

if "zlib" not in native.existing_rules():
    http_archive(
        name = "zlib",
        build_file = "@com_google_protobuf//:third_party/zlib.BUILD",
        sha256 = "91844808532e5ce316b3c010929493c0244f3d37593afd6de04f71821d5136d9",
        strip_prefix = "zlib-1.2.12",
        urls = ["https://zlib.net/zlib-1.2.12.tar.gz"],
    )

actually, at first I don't know the sha256 field. but after using bazel build again, it generates an error of wrong checksum, so I copied the checksum value to sha256 fileld and it worked finally.
