How to build ClickHouse on Linux
================================

Build should work on Linux Ubuntu 12.04, 14.04 or newer.
With appropriate changes, build should work on any other Linux distribution.
Build is not intended to work on Mac OS X.
Only x86_64 with SSE 4.2 is supported. Support for AArch64 is experimental.

To test for SSE 4.2, do

.. code-block:: bash

    grep -q sse4_2 /proc/cpuinfo && echo "SSE 4.2 supported" || echo "SSE 4.2 not supported"


Install Git and CMake
---------------------

.. code-block:: bash

    sudo apt-get install git cmake3


Detect number of threads
------------------------

.. code-block:: bash

    export THREADS=$(grep -c ^processor /proc/cpuinfo)

Install GCC 6
-------------

There are several ways to do it.

Install from PPA package
~~~~~~~~~~~~~~~~~~~~~~~~

.. code-block:: bash

    sudo apt-get install software-properties-common
    sudo apt-add-repository ppa:ubuntu-toolchain-r/test
    sudo apt-get update
    sudo apt-get install gcc-6 g++-6


Install from sources
~~~~~~~~~~~~~~~~~~~~

Example:

.. code-block:: bash

    # Download gcc from https://gcc.gnu.org/mirrors.html
    wget ftp://ftp.fu-berlin.de/unix/languages/gcc/releases/gcc-6.2.0/gcc-6.2.0.tar.bz2
    tar xf gcc-6.2.0.tar.bz2
    cd gcc-6.2.0
    ./contrib/download_prerequisites
    cd ..
    mkdir gcc-build
    cd gcc-build
    ../gcc-6.2.0/configure --enable-languages=c,c++
    make -j $THREADS
    sudo make install
    hash gcc g++
    gcc --version
    sudo ln -s /usr/local/bin/gcc /usr/local/bin/gcc-6
    sudo ln -s /usr/local/bin/g++ /usr/local/bin/g++-6
    sudo ln -s /usr/local/bin/gcc /usr/local/bin/cc
    sudo ln -s /usr/local/bin/g++ /usr/local/bin/c++
    # /usr/local/bin/ should be in $PATH


Use GCC 6 for builds
--------------------

.. code-block:: bash

    export CC=gcc-6
    export CXX=g++-6


Install required libraries from packages
----------------------------------------

.. code-block:: bash

    sudo apt-get install libicu-dev libreadline-dev libmysqlclient-dev libssl-dev unixodbc-dev


Checkout ClickHouse sources
---------------------------

To get latest stable version:

.. code-block:: bash

    git clone -b stable git@github.com:yandex/ClickHouse.git
    # or: git clone -b stable https://github.com/yandex/ClickHouse.git

    cd ClickHouse


For development, switch to the ``master`` branch.
For latest release candidate, switch to the ``testing`` branch.

Build ClickHouse
----------------

There are two variants of build.

Build release package
~~~~~~~~~~~~~~~~~~~~~

Install prerequisites to build debian packages.

.. code-block:: bash

    sudo apt-get install devscripts dupload fakeroot debhelper

Install recent version of clang.

Clang is embedded into ClickHouse package and used at runtime. Minimum version is 3.8.0. It is optional.


You can build clang from sources:

.. code-block:: bash

    cd ..
    sudo apt-get install subversion
    mkdir llvm
    cd llvm
    svn co http://llvm.org/svn/llvm-project/llvm/tags/RELEASE_400/final llvm
    cd llvm/tools
    svn co http://llvm.org/svn/llvm-project/cfe/tags/RELEASE_400/final clang
    cd ..
    cd projects/
    svn co http://llvm.org/svn/llvm-project/compiler-rt/tags/RELEASE_400/final compiler-rt
    cd ../..
    mkdir build
    cd build/
    cmake -D CMAKE_BUILD_TYPE:STRING=Release ../llvm
    make -j $THREADS
    sudo make install
    hash clang

Or install it from packages. On Ubuntu 16.04 or newer:

.. code-block:: bash

    sudo apt-get install clang


You may also build ClickHouse with clang for development purposes.
For production releases, GCC is used.

Run release script:

.. code-block:: bash

    rm -f ../clickhouse*.deb
    ./release

You will find built packages in parent directory:

.. code-block:: bash

    ls -l ../clickhouse*.deb


Note that usage of debian packages is not required.
ClickHouse has no runtime dependencies except libc, so it could work on almost any Linux.

Installing just built packages on development server:

.. code-block:: bash

    sudo dpkg -i ../clickhouse*.deb
    sudo service clickhouse-server start


Build to work with code
~~~~~~~~~~~~~~~~~~~~~~~

.. code-block:: bash

    mkdir build
    cd build
    cmake ..
    make -j $THREADS
    cd ..

To create an executable, run ``make clickhouse``.
This will create the ``dbms/src/Server/clickhouse`` executable, which can be used with --client or --server arguments.
