| This chapter describes SWIG usage on Microsoft Windows. |
| Installing SWIG and running the examples is covered as well as building the SWIG executable. |
| Usage within the Unix like environments MinGW and Cygwin is also detailed. |
| </p> |
| |
| |
| <H2><a name="Windows_installation"></a>3.1 Installation on Windows</H2> |
| |
| |
| <p> |
| SWIG does not come with the usual Windows type installation program, however it is quite easy to get started. The main steps are: |
| </p> |
| <ul> |
| <li>Download the swigwin zip package from the <a href="http://www.swig.org">SWIG website</a> and unzip into a directory. This is all that needs downloading for the Windows platform. |
| <li>Set environment variables as described in the <a href="#Windows_examples">SWIG Windows Examples</a> section in order to run examples using Visual C++. |
| </ul> |
| |
| <H3><a name="Windows_executable"></a>3.1.1 Windows Executable</H3> |
| |
| |
| <p> |
| The swigwin distribution contains the SWIG Windows executable, swig.exe, which will run on 32 bit versions of Windows, ie Windows 95/98/ME/NT/2000/XP. |
| If you want to build your own swig.exe have a look at <a href="#Windows_swig_exe">Building swig.exe on Windows</a>. |
| </p> |
| |
| |
| <H2><a name="Windows_examples"></a>3.2 SWIG Windows Examples</H2> |
| |
| |
| <p> |
| Using Microsoft Visual C++ is the most common approach to compiling and linking SWIG's output. |
| The Examples directory has a few Visual C++ project files (.dsp files). |
| These were produced by Visual C++ 6, although they should also work in Visual C++ 5. |
| Later versions of Visual Studio should also be able to open and convert these project files. |
| The C# examples come with .NET 2003 solution (.sln) and project files instead of Visual C++ 6 project files. |
| The project files have been set up to execute SWIG in a custom build rule for the SWIG interface (.i) file. |
| Alternatively run the <a href="#Windows_examples_cygwin">examples using Cygwin</a>. |
| |
| <p> |
| More information on each of the examples is available with the examples distributed with SWIG (Examples/index.html). |
| |
| <H3><a name="Windows_visual_studio"></a>3.2.1 Instructions for using the Examples with Visual Studio</H3> |
| |
| |
| <p> |
| Ensure the SWIG executable is as supplied in the SWIG root directory in order for the examples to work. |
| Most languages require some environment variables to be set <b>before</b> running Visual C++. |
| Note that Visual C++ must be re-started to pick up any changes in environment variables. |
| Open up an example .dsp file, Visual C++ will create a workspace for you (.dsw file). |
| Ensure the Release build is selected then do a Rebuild All from the Build menu. |
| The required environment variables are displayed with their current values. |
| </p> |
| <p> |
| The list of required environment variables for each module language is also listed below. |
| They are usually set from the Control Panel and System properties, but this depends on which flavour of Windows you are running. |
| If you don't want to use environment variables then change all occurrences of the environment variables in the .dsp files with hard coded values. |
| If you are interested in how the project files are set up there is explanatory information in some of the language module's documentation. |
| </p> |
| |
| <H4><a name="Windows_csharp"></a>3.2.1.1 C#</H4> |
| |
| |
| <p> |
| The C# examples do not require any environment variables to be set as a C# project file is included. |
| Just open up the .sln solution file in Visual Studio .NET 2003 or later, select Release Build, and do a Rebuild All from the Build menu. |
| The accompanying C# and C++ project files are automatically used by the solution file. |

| |
| |
| <p> |
| If you do not have access to Visual C++ you will have to set up project files / Makefiles for your chosen compiler. There is a section in each of the language modules detailing what needs setting up using Visual C++ which may be of some guidance. Alternatively you may want to use Cygwin as described in the following section. |
| </p> |
| |
| <H2><a name="Windows_cygwin_mingw"></a>3.3 SWIG on Cygwin and MinGW</H2> |
| |
| |
| <p> |
| SWIG can also be compiled and run using <a href="http://www.cygwin.com">Cygwin</a> or <a href="http://www.mingw.org">MinGW</a> which provides a Unix like front end to Windows and comes free with gcc, an ANSI C/C++ compiler. However, this is not a recommended approach as the prebuilt executable is supplied. |
| </p> |
| |
| <H3><a name="Windows_swig_exe"></a>3.3.1 Building swig.exe on Windows</H3> |
| |
| |
| <p> |
| If you want to replicate the build of swig.exe that comes with the download, follow the MinGW instructions below. |
| This is not necessary to use the supplied swig.exe. |
| This information is provided for those that want to modify the SWIG source code in a Windows environment. |
| Normally this is not needed, so most people will want to ignore this section. |
| </p> |
| |
| <H4><a name="Windows_mingw_msys"></a>3.3.1.1 Building swig.exe using MinGW and MSYS</H4> |
| |
| |
| <p> |
| The short abbreviated instructions follow... |
| </p> |
| |
| <ul> |
| <li>Install MinGW and MSYS from the <a href="http://www.mingw.org">MinGW</a> site. This provides a Unix environment on Windows. |
| <li>Follow the usual Unix instructions in the README file in the SWIG root directory to build swig.exe from the MinGW command prompt. |
| </ul> |
| |
| <p> |
| The step by step instructions to download and install MinGW and MSYS, then download and build the latest version of SWIG from SVN follow... |
| Note that the instructions for obtaining SWIG from SVN are also online at <a href="http://www.swig.org/svn.html">SWIG SVN</a>. |
| </p> |
| |
| <p> |
| <b>Pitfall note:</b> |
| Execute the steps in the order shown and don't use spaces in path names. In fact it is best to use the default installation directories. |
| </p> |
| |
| <ol> |
| <li> |
| Download the following packages from the <a href="http://www.mingw.org/download.shtml">MinGW download page</a> |
| or <a href="http://sourceforge.net/project/showfiles.php?group_id=2435">MinGW SourceForge download page</a>. |
| Note that at the time of writing, the majority of these are in the Current |
| release list and some are in the Snapshot or Previous release list. |
| <ul> |
| <li>MinGW-3.1.0-1.exe</li> |
| <li>MSYS-1.0.11-2004.04.30-1.exe</li> |
| <li>msysDTK-1.0.1.exe</li> |
| <li>bison-2.0-MSYS.tar.gz</li> |
| <li>msys-autoconf-2.59.tar.bz2</li> |
| <li>msys-automake-1.8.2.tar.bz2</li> |
| </ul> |
| </li> |
| |
| <li> |
| Install MinGW-3.1.0-1.exe (C:\MinGW is default location.) |
| </li> |
| |
| <li> |
| Install MSYS-1.0.11-2004.04.30-1.exe. Make sure you install it on the same |
| windows drive letter as MinGW (C:\msys\1.0 is default). |
| In the post install script, |
| <ul> |
| <li>Answer y to the "do you wish to continue with the post install?"</li> |
| <li>Answer y to the "do you have MinGW installed?"</li> |
| <li>Type in the the folder in which you installed MinGW (C:/MinGW is default)</li> |
| </ul> |
| </li> |
| |
| <li> |
| Install msysDTK-1.0.1.exe to the same folder that you installed MSYS (C:\msys\1.0 is default). |
| </li> |
| |
| <li> |
| Copy the followig to the MSYS install folder (C:\msys\1.0 is default): |
| <ul> |
| <li>msys-automake-1.8.2.tar.bz2</li> |
| <li>msys-autoconf-2.59.tar.bz2</li> |
| <li>bison-2.0-MSYS.tar.gz</li> |
| </ul> |
| </li> |
| |
| <li> |
| Start the MSYS command prompt and execute: |
| <div class="shell"><pre> |
| cd / |
| tar -jxf msys-automake-1.8.2.tar.bz2 |
| tar -jxf msys-autoconf-2.59.tar.bz2 |
| tar -zxf bison-2.0-MSYS.tar.gz |
| </pre></div> |
| </li> |
| |
| <li> |
| To get the latest SWIG SVN (version from Subversion source control), type in the following: |
| <div class="shell"><pre> |
| mkdir /usr/src |
| cd /usr/src |
| svn co https://swig.svn.sourceforge.net/svnroot/swig/trunk swig |
| </pre></div> |
| |
| <b>Pitfall note:</b> |
| If you want to check out SWIG to a different folder to the proposed |
| /usr/src/swig, do not use MSYS emulated windows drive letters, because |
| the autotools will fail miserably on those. |
| </li> |
| |
| <li> |
| You are now ready to build SWIG. Execute the following commands to build swig.exe: |
| <div class="shell"><pre> |
| cd /usr/src/swig |
| ./autogen.sh |
| ./configure |
| make |
| </pre></div> |
| </li> |
| </ol> |
| |
| |
| <H4><a name="Windows_cygwin"></a>3.3.1.2 Building swig.exe using Cygwin</H4> |
| |
| |
| <p> |
| Note that SWIG can also be built using Cygwin. |
| However, SWIG will then require the Cygwin DLL when executing. |
| Follow the Unix instructions in the README file in the SWIG root directory. |
| Note that the Cygwin environment will also allow one to regenerate the autotool generated files which are supplied with the release distribution. |
| These files are generated using the <tt>autogen.sh</tt> script and will only need regenerating in circumstances such as changing the build system. |
| </p> |
| |
| <H4><a name="Windows_building_alternatives"></a>3.3.1.3 Building swig.exe alternatives</H4> |
| |
| |
| <p> |
| If you don't want to install Cygwin or MinGW, use a different compiler to build |
| SWIG. For example, all the source code files can be added to a Visual C++ project |
| file in order to build swig.exe from the Visual C++ IDE. |
| </p> |
| |
| |
| <H3><a name="Windows_examples_cygwin"></a>3.3.2 Running the examples on Windows using Cygwin</H3> |
| |
| |
| <p> |
| The examples and test-suite work as successfully on Cygwin as on any other Unix operating system. |
| The modules which are known to work are Python, Tcl, Perl, Ruby, Java and C#. |
| Follow the Unix instructions in the README file in the SWIG root directory to build the examples. |
| </p> |
| |
| <H2><a name="Windows_interface_file"></a>3.4 Microsoft extensions and other Windows quirks</H2> |
| |
| |
| <p> |
| A common problem when using SWIG on Windows are the Microsoft function calling conventions which are not in the C++ standard. |
| SWIG parses ISO C/C++ so cannot deal with proprietary conventions such as <tt>__declspec(dllimport)</tt>, <tt>__stdcall</tt> etc. |
| There is a Windows interface file, <tt>windows.i</tt>, to deal with these calling conventions though. |
| The file also contains typemaps for handling commonly used Windows specific types such as <tt>__int64</tt>, <tt>BOOL</tt>, <tt>DWORD</tt> etc. |
| Include it like you would any other interface file, for example: |
| </p> |
| |
| <div class="code"><pre> |
| %include <windows.i> |
| |
| __declspec(dllexport) ULONG __stdcall foo(DWORD, __int32); |
| </pre></div> |
