Compiling ArangoDB under Windows

This guide describes how to compile ArangoDB 3.4 and onwards under Windows.

Install chocolatey

With ArangoDB 3.0 a complete cmake environment was introduced. This alsostreamlines the dependencies on Windows. We suggest to usechocolatey.org to install most ofthe dependencies. For sure most projects offer their own setup & installpackages, chocolatey offers a simplified way to install them with less userinteractions. You can even use chocolatey viaansibles 2.7 winrm facilityto do unattended installations of some software on Windows.

First install the choco package manager by pasting this tiny cmdlet into acommand window with Administrator privileges (press Windows key, type cmdand hit Ctrl+Shift+Enter):

  1. @powershell -NoProfile -ExecutionPolicy Bypass -Command "iex ((new-object net.webclient).DownloadString('https://chocolatey.org/install.ps1'))" && SET PATH=%PATH%;%ALLUSERSPROFILE%\chocolatey\bin

Visual Studio and its Compiler

Since choco currently fails to alter the environment forMicrosoft Visual Studio,we suggest to download and install Visual Studio by hand.Currently Visual Studio 2017 is the only supported option.

You need to make sure that it installs the Desktop development with C++ preset,else cmake will fail to detect it later on. Furthermore, the Windows 8.1 SDK and UCRT SDKoptional component is required to be selected during Visual Studio installation, else V8will fail to compile later on.

After it successfully installed, start it once, so it can finish its setup.

More Dependencies

Now you can invoke the choco package manager for an unattended install of the dependencies(needs to be run with Administrator privileges again):

  1. choco install -y cmake.portable nsis python2 procdump windbg wget

Then we need to install the OpenSSL library from its sources or using precompiledThird Party OpenSSL Related Binary Distributions.

Optional Dependencies

Remember that you need to run below commands with Administrator privileges!

If you want to checkout the code with git, install it like this:

  1. choco install -y git

You need to allow andenable symlinks for your user.

If you intend to run the unit tests, you also need the following:

  1. choco install -y winflexbison ruby

Close and reopen the Administrator command window in order to continue with the ruby devkit:

  1. choco install -y ruby2.devkit

And manually install the requirements via the Gemfile fetched from the ArangoDB Git repository(needs to be run with Administrator privileges):

  1. wget https://raw.githubusercontent.com/arangodb/arangodb/devel/tests/rb/HttpInterface/Gemfile
  2. setx PATH %PATH%;C:\tools\DevKit2\bin;C:\tools\DevKit2\mingw\bin
  3. gem install bundler
  4. bundler

Note that the V8 build scripts and gyp aren’t compatible with Python 3.x hence you need python2!

Building ArangoDB

Download and extract the release tarball fromwww.arangodb.com/download/

Or clone the GitHub repository and checkout the branch or tag you need (e.g. devel)

  1. git clone https://github.com/arangodb/arangodb.git -b devel
  2. cd arangodb

Generate the Visual studio project files, and check back that cmake discovered all components on your system:

  1. mkdir Build64
  2. cd Build64
  3. cmake -G "Visual Studio 15 2017 Win64" ..

Note that in some cases cmake struggles to find the proper python interpreter(i.e. the cygwin one won’t work). You can force overrule it by appending:

  1. -DPYTHON_EXECUTABLE:FILEPATH=C:/Python27/python.exe

You can now load these in the Visual Studio IDE or use cmake to start the build:

  1. cmake --build . --config RelWithDebInfo

The binaries need the ICU datafile icudt54l.dat, which is automatically copied into the directory containing theexecutable.

If you intend to use the machine for development purposes, it may be more practical to copy it to a common place:

  1. cd 3rdParty/V8/v*/third_party/icu/source/data/in && cp icudt*.dat /cygdrive/c/Windows/

And configure your environment (yes this instruction remembers to the hitchhikers guide to the galaxy…) so thatICU_DATA points to c:\Windows. You do that by opening the explorer,right click on This PC in the tree on the left, choose Properties in the opening window Advanced system settings,in the Popup Environment Variables, another popup opens, in the System Variables part you click New, And variable name: ICU_DATA to the value: c:\Windows

HowtoSetEnv

Unit tests (Optional)

The unit tests require a cygwin environment.

You need at least make from cygwin. Cygwin also offers a cmake. Do not install the cygwin cmake.

You should also issue these commands to generate user information for the cygwin commands:

  1. mkpasswd > /etc/passwd
  2. mkgroup > /etc/group

Turning ACL off (noacl) for all mounts in cygwin fixes permissions troubles that may appear in the build:

  1. # /etc/fstab
  2. #
  3. #    This file is read once by the first process in a Cygwin process tree.
  4. #    To pick up changes, restart all Cygwin processes.  For a description
  5. #    see https://cygwin.com/cygwin-ug-net/using.html#mount-table
  7. # noacl = Ignore Access Control List and let Windows handle permissions
  8. C:/cygwin64/bin  /usr/bin   ntfs      binary,auto,noacl           0  0
  9. C:/cygwin64/lib  /usr/lib   ntfs      binary,auto,noacl           0  0
  10. C:/cygwin64      /          ntfs      override,binary,auto,noacl  0  0
  11. none             /cygdrive  cygdrive  binary,posix=0,user,noacl   0  0

Cygwin will create proprietary files as placeholders by default instead ofactually symlinking files. The placeholders later tell Cygwin where to resolvepaths to. It does not intercept every access to the placeholders however, sothat 3rd party scripts break. Windows Vista and above support real symlinks,and Cygwin can be configured to make use of it:

  1. # use actual symlinks to prevent documentation build errors
  2. # (requires elevated rights!)
  3. export CYGWIN="winsymlinks:native"

Note that you must run Cygwin as administrator or change the Windows grouppolicies to allow user accounts to create symlinks (gpedit.msc if available).

BTW: You can create symlinks manually on Windows like:

  1. mklink /H target/file.ext source/file.ext
  2. mklink /D target/path source/path
  3. mklink /J target/path source/path/for/junction

And in Cygwin:

  1. ln -s source target

Running Unit tests

You can then run the integration tests in the cygwin shell like that:

  1. Build64/bin/RelWithDebInfo/arangosh.exe \
  2. -c etc/relative/arangosh.conf \
  3. --log.level warning \
  4. --server.endpoint tcp://127.0.0.1:1024 \
  5. --javascript.execute UnitTests/unittest.js \
  6.   -- \
  7.   all \
  8.   --build Build64 \
  9.   --buildType RelWithDebInfo \
  10.   --skipNondeterministic true \
  11.   --skipTimeCritical true \
  12.   --skipBoost true \
  13.   --skipGeo true

Additional options —ruby c:/tools/ruby25/bin/ruby and —rspec c:/tools/ruby25/bin/rspecshould be used only if Ruby is not in the PATH.
