[riscv][risc-v][riscv64]Cannot build Bazel 7.1.0 on RISC-V 64 (Lichee PI4A)

[lazyprogrammerio]

Description of the bug:

Hello,

I am running Ubuntu 24.04 stock (riscv64) on the LicheePi 4A.

When trying to build bazel from source (7.1.0), I get an error, as it weirdly tries to build Bazel with Bazel (?) and it fails.

My first question is: why is it trying to build Bazel with Bazel -> Building Bazel with Bazel?

Reproduction steps:

# download and unzip / cd into bazel-7.1.0-dist.zip
# apt install java 21 jre and jdk
# dpkg --list |grep -i jdk

[lazyprogrammerio]

Seems like https://github.com/bazelbuild/rules_python/pull/1907/files is required to be able to build on riscv64.
bazelbuild/rules_python@daf4224 -> present in version 0.33+ of the rules_python.

Which means that only Bazel v8.00+ will be able to properly build, see 01f6dec.

One has to backport this commit 01f6dec to 7.1.0 and hope it builds.

[lazyprogrammerio]

From the documentation, I do not see a way to bootstrap without having a .dist release, how can I do it though with the git repo? Otherwise, I ll need to wait for a new tag and a release of 8.x.

[lazyprogrammerio]

RISC-V master is broken because this commit has been reverted/changed b34be09 and it was not applied when it got reverted in the main repo and the functionality was switched to using the bazel_rules repository https://github.com/bazelbuild/rules_java/blame/master/toolchains/BUILD#L141

I opened a PR here: bazelbuild/rules_java#198

@lazyprogrammerio hi
i am working on building tensorflow2.15.0 from source by bazel6.1.0.
i notice that the WORKFILE in tensorflow2.15.0 point to the rules_python is 0.26.0, which not support risc-v.
when i change the 0.26.0 to 0.33.0, i meet the error:

ERROR: /home/tf2150/tensorflow/WORKSPACE:61:10: //external:pypi: no such attribute 'requirements' in 'pip_repository' rule
ERROR: Error computing the main repository mapping: Encountered error while reading extension file 'requirements.bzl': no such package '@pypi//': error loading package 'external': Could not load //external package

you know something about it?
thanks very much!
