To perform a Bazel build via SCons:

• You must be on a arm64 virtual workstation
• Build the Bazel-compatible target: python3 ./buildscripts/scons.py BAZEL_BUILD_ENABLED=1 --build-profile=fast --ninja=disabled --link-model=static -j 200 --modules= build/fast/mongo/db/commands/libfsync_locked.a

To perform a Bazel build and bypass SCons:

• Install Bazelisk: curl -L https://github.com/bazelbuild/bazelisk/releases/download/v1.17.0/bazelisk-linux-arm64 --output /tmp/bazelisk && chmod +x /tmp/bazelisk
• Build the Bazel-compatible target: /tmp/bazelisk build --verbose_failures src/mongo/db/commands:fsync_locked

To perform a Bazel build using a local Buildfarm (to test remote execution capability):

• For more details on Buildfarm, see https://bazelbuild.github.io/bazel-buildfarm
• (One time only) Build and start the Buildfarm: ** Change into the buildfarm directory: cd buildfarm ** Build the image: docker-compose build ** Start the container: docker-compose up --detach ** Poll until the containers report status running: docker ps --filter status=running --filter name=buildfarm
• (Whenever you build): ** Build the Bazel-compatible target with remote execution enabled: /tmp/bazelisk build --verbose_failures --remote_executor=grpc://localhost:8980 src/mongo/db/commands:fsync_locked
