Apertium on Windows

We are in the process of porting Apetium to Windows. Lttoolbox has already been compiled successfully, but has not been tested extensively. We are now working on porting Apertium.

Getting the code

The Windows branch is currently in the unofficial GIT repository under the "windows" branch. To contribute, first follow the steps on Using the Apertium GIT repository. Now, we'll create a branch called "windows", which will track the "windows" branch in the remote repository:

  git branch --track windows origin/windows

To switch to the "windows" branch, issue:

  git checkout windows

Dependencies

You will need to get Windows versions of the following tools and libraries to compile the code under Windows:

• Microsoft's C++ compiler - the compiler is part of Visual Studio 2008 Express, which is available free of charge.
• CMake - a cross platform build tool
• libxml - the Windows binaries are at http://xmlsoft.org/sources/win32/; you will need:
  • libxml2
  • zlib
  • libiconv
  • libxslt
• libpcre - there are no Windows binaries available and you will have to build this from the source code.
• flex for Windows - it's probably easiest if you just download the Windows installer version.

Setting up the required tools and libraries

Installing Visual Studio

Be sure to start downloading Visual Studio 2008 first, since it is a fairly big download.

Installing CMake

Next, download and install the Windows version of CMake. Let the installer place CMake in your path, since it will be much easier to run CMake from the command line if you do this.

Installing the libxml libraries

The zip files of libxml2, zlib, libiconv and libxslt all have the familiar UNIX layout:

|- bin
|- include
|- lib
|- share

Unzip each of these archives and copy the bin, include, lib and share directories in each package into a common directory (for example C:\Program Files\libxml2).

Building and installing libpcre

Now, unzip the libpcre archive to a temporary folder. To compile libpcre, you will need have Visual Studio AND CMake already installed on your system. Now, open the Visual Studio 8.0 Command Prompt (Start -> Visual C++ 9.0 Express Edition -> Visual Studio Tools -> Visual Studio 8.0 Command Prompt). In this command prompt, go to the directory where you unpacked libpcre. Execute:

cmakesetup .

Click the button labelled "Configure". After CMake has gone through its motions, click OK. To compile libpcre, run:

nmake

After the compilation has succeeded, run:

nmake install

Provided that you haven't changed any setting when you ran the cmakesetup program, libpcre should install to C:\Program Files\PCRE.

Installing flex

If you have downloaded the binary archive, unzip them into something like C:\Program Files\Flex. If you downloaded the Windows installer, then just follow the installation wizard :).
