Building CockroachDB - linux-on-ibm-z/docs GitHub Wiki

Building CockroachDB

The instructions provided below specify the steps to build CockroachDB version 25.4.2 on Linux on IBM Z for the following distributions:

  • RHEL (8.10, 9.4, 9.6, 9.7, 10.0, 10.1)
  • Ubuntu (22.04, 24.04, 25.10)

Important Notes:

  • You need to enable the EPEL repositories on RHEL distros. This can be done by installing the epel-release package:

    • RHEL 8.10

      sudo subscription-manager repos --enable codeready-builder-for-rhel-8-$(arch)-rpms
sudo dnf install https://dl.fedoraproject.org/pub/epel/epel-release-latest-8.noarch.rpm

    • RHEL (9.4, 9.6, 9.7)

      sudo subscription-manager repos --enable codeready-builder-for-rhel-9-$(arch)-rpms
sudo dnf install https://dl.fedoraproject.org/pub/epel/epel-release-latest-9.noarch.rpm

    • RHEL (10.0, 10.1)

      sudo subscription-manager repos --enable codeready-builder-for-rhel-10-$(arch)-rpms
sudo dnf install https://dl.fedoraproject.org/pub/epel/epel-release-latest-10.noarch.rpm

General Notes:

  • When following the steps below please use a standard permission user unless otherwise specified.
  • A directory /<source_root>/ will be referred to in these instructions, this is a temporary writable directory anywhere you'd like to place it.

1. Build using script

If you'd like to build CockroachDB using the manual steps, please go to STEP 2.

Use the following commands to build CockroachDB using the build script. Please make sure you have wget installed.

wget -q https://raw.githubusercontent.com/linux-on-ibm-z/scripts/master/CockroachDB/25.4.2/build_crdb.sh

# Build CockroachDB
bash build_crdb.sh   [Provide -t option for executing build with tests]

If the build completes successfully, go to STEP 5. In case of error, check logs for more details or go to STEP 2 to follow manual build steps

cp $SOURCE_ROOT/bazel-lib.patch .
cat <<EOF >BUILD
filegroup(
    name = "bazel-lib.patch",

echo 'build --config=dev
build --config nolintonbuild' >> .bazelrc.user
echo "test --test_tmpdir=$SOURCE_ROOT/cockroach/tmp" >> .bazelrc.user

sudo cp cockroach /usr/local/bin
sudo mkdir -p /usr/local/lib/cockroach
sudo cp _bazel/bin/c-deps/libgeos_foreign/lib/libgeos.so /usr/local/lib/cockroach/
sudo cp _bazel/bin/c-deps/libgeos_foreign/lib/libgeos_c.so /usr/local/lib/cockroach/
export PATH=$SOURCE_ROOT/cockroach:$PATH

4. Testing (Optional)

cd $SOURCE_ROOT/cockroach
./dev test -v -- --test_timeout=3600

Note:

  • Some test cases might experience time out problem. They should pass after increasing the timeout and running the test again. And remaining test cases will pass on re-run.

5. Verify
