How to Build ClickHouse on Linux for AARCH64 (ARM64) architecture

This is for the case when you have Linux machine and want to use it to build clickhouse binary that will run on another Linux machine with AARCH64 CPU architecture. This is intended for continuous integration checks that run on Linux servers.

The cross-build for AARCH64 is based on the Build instructions, follow them first.

Install Clang-8

Follow the instructions from https://apt.llvm.org/ for your Ubuntu or Debian setup.
For example, in Ubuntu Bionic you can use the following commands:

  1. echo "deb [trusted=yes] http://apt.llvm.org/bionic/ llvm-toolchain-bionic-8 main" | sudo tee /etc/apt/sources.list.d/llvm.list
  2. sudo apt-get update
  3. sudo apt-get install clang-8

Install Cross-Compilation Toolset 

  1. cd ClickHouse
  2. mkdir -p build-aarch64/cmake/toolchain/linux-aarch64
  3. wget 'https://developer.arm.com/-/media/Files/downloads/gnu-a/8.3-2019.03/binrel/gcc-arm-8.3-2019.03-x86_64-aarch64-linux-gnu.tar.xz?revision=2e88a73f-d233-4f96-b1f4-d8b36e9bb0b9&la=en' -O gcc-arm-8.3-2019.03-x86_64-aarch64-linux-gnu.tar.xz
  4. tar xJf gcc-arm-8.3-2019.03-x86_64-aarch64-linux-gnu.tar.xz -C build-aarch64/cmake/toolchain/linux-aarch64 --strip-components=1

Build ClickHouse 

  1. cd ClickHouse
  2. mkdir build-arm64
  3. CC=clang-8 CXX=clang++-8 cmake . -Bbuild-arm64 -DCMAKE_TOOLCHAIN_FILE=cmake/linux/toolchain-aarch64.cmake
  4. ninja -C build-arm64

The resulting binary will run only on Linux with the AARCH64 CPU architecture.
