Remote Build Failure with Kleaf on Android Common Kernel (14-6.1): Missing libcrypto-host.so

[DhanalakshmiDurairaj]

Hi everyone,

I am trying to build the Android Common Kernel (repo: common-android14-6.1) using Kleaf with Remote Build Execution (RBE). I'm using our own cluster setup with Buildfarm.

• Host platform: Ubuntu 20.04
• Cluster machines: Ubuntu 20.04
• bazel version:8.3.1
• Reference: Android Kernel Build Guide

The command I am running is:

tools/bazel run //common:kernel_aarch64_dist \
  --config=remote \
  --remote_executor=grpc://<IP_ADDRESS>:<PORT> \
  -- --destdir=out_dir

I got this error:
/path/android-kernel/build/kernel/BUILD.bazel:31:15: Creating wrapper for tar: @//build/kernel:hermetic-tools [for tool] failed: (Exit 127): bash failed: error executing HermeticToolsTar command (from target //build/kernel:hermetic-tools) /bin/bash -c ... (remaining 1 argument skipped)
realpath: error while loading shared libraries: libcrypto-host.so: cannot open shared object file: No such file or directory
Target //common:kernel_aarch64_dist failed to build

Is there a recommended way to resolve this, especially when using Buildfarm for remote execution?

Any help or suggestions would be greatly appreciated!

Thanks,
