[7.7.0] Add support for riscv64 linux by kxxt · Pull Request #25699 · bazelbuild/bazel

kxxt · 2025-03-26T04:31:39Z

This patch brings enough support for bootstraping bazel itself on riscv64 linux platform.

Changes:

Bump rules_java for [7.x] Add JDK 21 toolchain for linux_riscv64 rules_java#282 Fix jni_md.h not found on linux_mips64 and linux_riscv64 rules_java#198
Use portable uname -m in mininize_jdk.sh (8.x: Add support for riscv64 linux #25236)
Bump stardoc to 0.7.1 and rules_jvm_external to 6.2 to fix CI failure
Add prebuilt jdk for riscv64
Bump abseil-cpp for unscaledcycleclock: remove RISC-V support abseil/abseil-cpp#1644

Tested on riscv 64 linux by bazel build //src:bazel --compilation_mode=opt

kxxt · 2025-03-26T04:46:49Z

Looks like the bump of stardoc brings some incompatible changes.

kxxt · 2025-03-26T11:48:03Z

Looks like the bump of stardoc brings some incompatible changes.

Fixed by bumping stardoc again to 0.7.1 (and bumping rules_jvm_external to 6.1 as a result)

The CI is complaining about lockfile not up to date. It is confusing as when I tried to update the lockfile locally, no change happened.

Hi @kxxt
Unfortunately, we are not planning another Bazel 7 release yet. However, if we do have another release, then we'll come back to this one and include the fix. Thank you!

Hi @kxxt Unfortunately, we are not planning another Bazel 7 release yet. However, if we do have another release, then we'll come back to this one and include the fix. Thank you!

Then I will keep this patch at downstream distro packaging for a while. Thanks!

Add riscv64 support to bazel7: Upstreamed as bazelbuild/bazel#25699 Upstream is currently not planning another bazel 7 release so we need to keep this patch at downstream for a while.

kxxt · 2025-03-31T04:10:31Z

I have changed the base branch to 7.6.1 and bumped rules_jvm_external again, which should fix the lockfile issue.

iancha1992 · 2025-09-12T21:36:30Z

@bazel-io fork 7.7.0

kxxt · 2025-09-17T04:25:45Z

The CI is failing with "ERROR: Error computing the main repository mapping: Error accessing registry https://bcr.bazel.build/: Failed to fetch registry file https://bcr.bazel.build/modules/rules_java/7.12.5/MODULE.bazel: Unknown host: bcr.bazel.build" error.

I am not sure what to do to fix it as it looks like a DNS/hosts configuration problem.

iancha1992 · 2025-09-17T18:16:37Z

@kxxt Can you please get this one merged to the master first? We'll cherry-pick the commit to the release branches after.

kxxt · 2025-09-17T23:39:36Z

@kxxt Can you please get this one merged to the master first? We'll cherry-pick the commit to the release branches after.

It is already in master: #25236 . But a cherry-pick is not sufficient, as more dependency bumps are required to make riscv64 support work on v7.

Unfortunately this didn't make it for 7.7.0 release, I'll have to close this one. We could backport to 8.5.0 if you want.
