tlm - Top-level Makefile

What's this, then? The tlm project contains the make information for building Couchbase on multiple platforms.

Table of Contents

Content

The file named CMakeLists.txt contains the full build description for Couchbase. It should be copied to the top of your source directory (this happens automatically when you are using repo).

The cmake directory contains macros used by cmake to configure a build of Couchbase.

Makefile is a convenience file that repo will put in the root of your source directory. It invokes cmake with a specific set of options. "All" flavors of make should be able to parse this makefile, and its defaults are set to match building on Microsoft Windows.

GNUmakefile is another convenience file that repo will put in the root of your source directory. GNU make will favor this file over Makefile and this file just overrides the defaults specified in Makefile.

How to build

Couchbase utilize CMake in order to provide build support for a wide range of platforms. CMake isn't a build system like GNU Autotools, but a tool that generates build information for external systems like: Visual Studio projects, XCode projects and Makefiles to name a few. Their good support for Microsoft Windows and Makefiles is the primary reason why we decided to move away from GNU Autotools. CMake isn't a magic pill that solved all our problems; it comes with its own list of challenges.

It is recommended to perform "out of source builds", which means that the build artifacts is stored outside the source directory.

Simple build

If you just want to build Couchbase and without any special configuration, you may use the Makefile we've supplied for your convenience:

trond@ok > mkdir source
trond@ok > mkdir build
trond@ok > cd source
trond@ok source> repo init -u git://github.com/couchbase/manifest -m branch-master.xml
trond@ok source> repo sync
trond@ok source> make

This would install the build software in a subdirectory named install. To change this you may run:

trond@ok source> make PREFIX=/opt/couchbase

Customize your builds

CMake offers a wide range of customizations, and this chapter won't try to cover all of them. There is plenty of documentation available on the webpage.

There is no point of trying to keep a list of all tunables in this document. To find the tunables you have two options: look in cmake/Modules/*.cmake or you may look in the cache file generated during a normal build (see build/CMakeCache.txt)

There are two ways to customize your own builds. You can do it all by yourself by invoking cmake yourself:

trond@ok > mkdir source
trond@ok > mkdir build
trond@ok > cd source
trond@ok source> repo init -u git://github.com/couchbase/manifest -m branch-master.xml
trond@ok source> repo sync
trond@ok source> cd ../build
trond@ok build> cmake -D CMAKE_INSTALL_PREFIX=/opt/couchbase -D CMAKE_BUILD_TYPE=Debug -D ERLANG_FOUND:BOOL=True -D ERLANG_INCLUDE_PATH:PATH=/opt/r14b04/lib/erlang/usr/include -D ERLC_EXECUTABLE:FILEPATH=/opt/r14b04/bin/erlc -D ERL_EXECUTABLE:FILEPATH=/opt/r14b04/bin/erl -D ESCRIPT_EXECUTABLE:FILEPATH=/opt/r14b04/bin/escript -DREBAR_SCRIPT=/root/src/repo3/tlm/cmake/Modules/rebar -G "Unix Makefiles" ../source
trond@ok build> gmake all install

Or pass extra options to the convenience Makefile provided:

trond@ok > mkdir source
trond@ok > mkdir build
trond@ok > cd source
trond@ok source> repo init -u git://github.com/couchbase/manifest -m branch-master.xml
trond@ok source> repo sync
trond@ok source> make PREFIX=/opt/couchbase EXTRA_CMAKE_OPTIONS='-D ERLANG_FOUND:BOOL=True -D ERLANG_INCLUDE_PATH:PATH=/opt/r14b04/lib/erlang/usr/include -D ERLC_EXECUTABLE:FILEPATH=/opt/r14b04/bin/erlc -D ERL_EXECUTABLE:FILEPATH=/opt/r14b04/bin/erl -D ESCRIPT_EXECUTABLE:FILEPATH=/opt/r14b04/bin/escript -DREBAR_SCRIPT=/root/src/repo3/tlm/cmake/Modules/rebar'

Microsoft Windows 2008R2

The following steps is needed to build Couchbase on Microsoft Windows 2008R2

  • Install OS, activate and run Windows Update and install all updates
  • Install Google Chrome (optional, but makes your life easier)
  • Install Visual Studio 2013 Professional
  • Install all updates from microsoft update
  • Install GIT and select the option to add GIT to path
  • Install Python 2.7 and add c:\python27 to path (manually)
  • Install 7-ZIP and add the installation to path (manually)
  • Install CMake and add to path
  • Install GO and add to path
  • Download and install 2008 runtime extensions
  • Create a directory named c:\tools and add it to your path.. Copy environment.bat and repo.exe from the google drive folder into this directory (@todo figure out where to store them)
  • Copy the directory depot from google drive to c:\ (endind up as: c:\depot)

Configuration

git

Repo will complain if git isn't properly configured. Setting name and email should be sufficient

C:\> git config --global user.email trond.norbye@gmail.com
C:\> git config --global user.name "Trond Norbye"

How to build

Before you may start to build on Microsoft Windows you have to set up the environment.

Open cmd.com and type in the following (assuming c:\compile\couchbase is the directory holding your source):

C:\> set source_root=c:\compile\couchbase
C:\> set target_platform=amd64
C:\> environment

You may now follow the build description outlined in How to build. Please note that the make utility on windows is named nmake.

MacOSX

Multiple versions of Mac OSX may work, but this list is verified with Mavericks.

Install the following packages from homebrew:

trond@ok> brew install cmake erlang git icu4c libevent snappy v8

Ensure that your PATH variable includes /usr/local/opt/icu4c/bin:

trond@ok> export PATH=$PATH:/usr/local/bin:/usr/local/opt/icu4c/bin

You should be all set to start compile the server as described above.

SmartOS

The following chapters describes how to configure and build under various containers hosted by SmartOS. [Joyent][joyent_link] provides a variety of datasets for various operating systems (CentOS, Fedora, FreeBSD, Debian, SmartOS, ...). This section is not intended to cover all of these, but covers a set of configurations known to work.

CentOS 6

The following descrtiption use the Centos-6 image imported by:

root@smartos~> imgadm import df81f45e-8f9f-11e3-a819-93fab527c81e

The KVM may be created with the following attributes (store in centos.json):

{
  "alias": "centos-6",
  "brand": "kvm",
  "resolvers": [
    "10.0.0.1",
    "8.8.4.4"
  ],
  "default-gateway": "10.0.0.1",
  "hostname": "centos",
  "ram": "2048",
  "vcpus": "2",
  "nics": [
    {
      "nic_tag": "admin",
      "ip": "10.0.0.201",
      "netmask": "255.255.255.0",
      "gateway": "10.0.0.1",
      "model": "virtio",
      "primary": true
    }
  ],
  "disks": [
    {
      "image_uuid": "325dbc5e-2b90-11e3-8a3e-bfdcb1582a8d",
      "boot": true,
      "model": "virtio",
      "image_size": 10240
    }
  ],
  "customer_metadata": {
    "root_authorized_keys": "ssh-rsa <my-personal-public-key>"
  }
}

Create the KVM with:

root@smartos~> vmadm create -f centos.json

You should now be able to ssh into the machine and run yum update and install all of the updates ;-)

Install as much as possible of the precompiled dependencies with:

root@centos~> yum install -y libevent-devel libicu-devel \
                             snappy-devel gcc gcc-c++ libcurl-devel \
                             make ncurses-devel openssl-devel svn \
                             expat-devel perl-ExtUtils-CBuilder \
                             perl-ExtUtils-MakeMaker tcl gettext

Unfortunately the YUM repository don't include all (and new enough) versions of all we need, so you need to install the following from source:

wget http://www.cmake.org/files/v2.8/cmake-2.8.12.1.tar.gz
wget http://download.savannah.gnu.org/releases/libunwind/libunwind-1.1.tar.gz
wget https://gperftools.googlecode.com/files/gperftools-2.1.tar.gz
wget -Ov1.9.2.tar.gz https://github.com/git/git/archive/v1.9.2.tar.gz
wget --no-check-certificate -Ov8.tar.gz \
     https://github.com/v8/v8/archive/3.19.0.tar.gz
wget http://www.erlang.org/download/otp_src_R16B03.tar.gz

gtar xfz cmake-2.8.12.1.tar.gz
gtar xfz libunwind-1.1.tar.gz
gtar xfz gperftools-2.1.tar.gz
gtar xfz v1.9.2.tar.gz
gtar xfz v8.tar.gz
gtar xfz otp_src_R16B03.tar.gz

cd git-1.9.2
gmake prefix=/usr install
cd ../cmake-2.8.12.1
./bootstrap && gmake all install
cd ../libunwind-1.1
./configure && gmake all install
cd ../gperftools-2.1
./configure && gmake all install
cd ../v8-3.19.0
gmake dependencies
gmake x64 library=shared -j 4
cp out/x64.release/lib.target/libv8.so /usr/local/lib
cp include/* /usr/local/include/
cd ../otp_src_R16B03
CFLAGS="-DOPENSSL_NO_EC=1" ./configure && gmake all install
cd ..

Install Google repo and you should be all set to start building the code as described above.

Ubuntu

The following descrtiption use the Ubuntu image imported by:

root@smartos~> imgadm import d2ba0f30-bbe8-11e2-a9a2-6bc116856d85

The KVM may be created with the following attributes (store in ubuntu.json):

{
  "alias": "ubuntu",
  "brand": "kvm",
  "resolvers": [
    "10.0.0.1",
    "8.8.4.4"
  ],
  "default-gateway": "10.0.0.1",
  "hostname":"ubuntu",
  "ram": "2048",
  "vcpus": "2",
  "nics": [
    {
      "nic_tag": "admin",
      "ip": "10.0.0.202",
      "netmask": "255.255.255.0",
      "gateway": "10.0.0.1",
      "model": "virtio",
      "primary": true
   }
  ],
  "disks": [
    {
      "image_uuid": "d2ba0f30-bbe8-11e2-a9a2-6bc116856d85",
      "boot": true,
      "model": "virtio",
      "image_size": 16384
    }
  ],
  "customer_metadata": {
    "root_authorized_keys": "ssh-rsa <my-personal-public-key>"
  }
}

Create the KVM with:

root@smartos~> vmadm create -f ubuntu.json

You should now be able to ssh into the machine and run aptitude and install all of the updates ;-)

Install as much as possible of the precompiled dependencies with:

root@ubuntu~> apt-get install -y git automake autoconf libtool clang \
                                 clang++ libevent-dev libicu-dev \
                                 libsnappy-dev libunwind7-dev erlang \
                                 libv8-dev make ccache ibcurl4-openssl-dev

A newer version of cmake and google perftools is needed so we have to compile them from source with:

wget http://www.cmake.org/files/v2.8/cmake-2.8.12.1.tar.gz
tar xfz cmake-2.8.12.1.tar.gz
cd cmake-2.8.12.1
./bootstrap && make && make install
cd ..
wget https://gperftools.googlecode.com/files/gperftools-2.1.tar.gz
tar xfz gperftools-2.1.tar.gz
cd gperftools-2.1
./configure && make && make install

Install Google repo and you should be all set to start building the code as described above.
