| − | ===Compiler===
| + | |
| − | To compile [[FreeOrion]] you can use the MSVC 2005 or MSVC 2008 IDEs or SCons. In any case, the MSVC compiler is required and will be used; compiling with SCons is done from the command-line, but uses the same compiler as the IDE. The 2003 compiler is no longer supported due to bugs which prevent FreeOrion from compiling.
| + | |
| − | | + | |
| − | Visual Studio 2008 Express Edition may be [http://www.microsoft.com/express/vc/ downloaded for free] from Microsoft. Due to different registry keys being used, the Express Edition compiler may not be compatible with SCons, so if the newest version of SCons doesn't work, you'll have to use the project files to compile FreeOrion.
| + | |
| − | | + | |
| − | If you are a student, you may also be elligable for [http://www.dreamspark.com Microsoft Dreamspark], which will give you the full versions of MSVC 2008 or 2005 or several other Microsoft programs.
| + | |
| − | | + | |
| − | The commercial version of the Visual Studio 2005 compiler can be used with SCons or with the project files.
| + | |
| − | | + | |
| − | Note that the MSVC 2005 Service Pack 1 is required for FreeOrion to compile properly.
| + | |
| − | | + | |
| − | ===Software Dependencies===
| + | |
| − | The majority of FreeOrion dependencies can be found precompiled and packaged in the FreeOrion Windows SDK, from the [http://sourceforge.net/project/showfiles.php?group_id=75752&package_id=236893 SourceForge downloads page].
| + | |
| − | | + | |
| − | The SDK includes compiled libraries, headers and DLLs for: [[zlib]], OGRE, bullet, GraphViz, Boost, FreeType, GLEW, libpng, libjpeg, OpenAL, libvorbis, and libogg.
| + | |
| − | | + | |
| − | Other dependencies include:
| + | |
| − | | + | |
| − | * [http://www.python.org/download/ Python 2.5] - Needed for the SCons build system, and FreeOrion AI
| + | |
| − | | + | |
| − | * [http://www.scons.org/ SCons] - Optional for building FreeOrion and the GiGi libraries
| + | |
| − | | + | |
| − | * '''GiGi''' - Including '''GiGiOgre''' and '''GiGiOgrePlugin_OIS'''. These are included in the FreeOrion SDK. If building FreeOrion using SCons, GiGi but must be built from source and installed. The MSVC project files contain projects for the GiGi GiGi libraries that are needed by FreeOrion, and the DLLs .lib files will be placed in the FreeOrion folder when built. All GiGi dependencies are in the FreeOrion SDK and should be automatically detected when GiGi is built.
| + | |
| − | | + | |
| − | Depending on the compiler you're using and the versions of library and dll files in the SDK, you might need to compile some on your own. If you're using a version of the MSVC compiler other than 2008, [[zlib|zlib and libpng]] need to be compiled; the version in the SDK probably, which was built with MSVC 2008 probably will not work with another compiler. Similarly, the boost libraries in the SDK were built with MSVC 2008 and you may need to build or download other versions for other compilers.
| + | |
| − | | + | |
| − | If you need Boost libraries, there are Win32 installers available from [http://www.boostpro.com/products/free BoostPro Computing]. As of this writing, you want to install the headers, and the '''Multithreaded DLL''' versions of these libraries: '''date_time''', '''filesystem''', '''python''', '''regex''', '''serialization''', '''signals''', '''system''', and '''thread'''.
| + | |
| − | | + | |
| − | If you are building the [http://www.bulletphysics.com/Bullet/wordpress/ Bullet] physics library from source, the Bullet SDK provides project files for MSVC 2005. Only the library projects are needed to link with FreeOrion, not the App or Demo projects. Note that you need to modify the Project Properties -> C++ -> Code Generation -> Runtime Library to '''Multi-threaded DLL (/MD)''' and not a debug-related setting, otherwise you will get linking errors when trying to link the Bullet libraries with FreeOrion. The '''libbulletcollision''' and '''libbulletmath''' libraries and DLLs are used by FreeOrion.

| − | ==Compilation Instructions==
| + | |
| − | # First, get the [http://sourceforge.net/project/showfiles.php?group_id=75752&package_id=236893 FreeOrion SDK] from SourceForge. | + | |
| − | # Optionally, update FreeOrion to the latest revision in [[Compile#Subversion|SVN]] which should automatically also update GiGi.
| + | |
| − | | + | |
| − | | + | |
| − | | + | |
| − | ===Compiling with MSVC 2008 IDE===
| + | |
| − | # Open msvc2008\FreeOrion\FreeOrion.sln
| + | |
| − | # Configure the Python include and lib directories to where these are located on your system. These are accessed in the GUI at (Project->Properties->C/C++->General) and (Project->Properties->Linker->General). This is essential only for the "freeorionca" project, but all three projects have the directories in their settings by default.
| + | |
| − | # Use Build->Build Solution to build the three projects' release targets
| + | |
| − | | + | |
| − | | + | |
| − | If you get a crash right after running freeorion.exe before the program shows the intro splash screen, you may need to built zlib1.dll and libpng13.dll with MSVC 2008 due to incompatibility with the versions in the SDK, which were built with an earlier version of MSVC's compiler. See [[zlib|here]] for instructions, which are unfortunately not completely straightforward.
| + | |
| − | | + | |
| − | | + | |
| − | ===Compiling with SCons===
| + | |
| − | # If not done already, get SCons and Python ([[Compile_In_Windows#Software_Dependencies|see above]])
| + | |
| − | # Build and install GiGi using the instructions in README.txt in the SDK
| + | |
| − | # Follow the instructions in the FreeOrion SDK, as with GiGi.
| + | |
| − | | + | |
| − | Note that '''using SCons reduces compile time''' compared to compiling with the MSVC IDE, because common object files are only built one time instead of once for each executable.
| + | |
| − | | + | |
| − | As noted with for the MSVC 2008 IDE above, if you are compiling using the MSVC 2008 compiler and the FreeOrion SDK, you may get a crash when freeorion.exe starts. See above for a solution.

| − | ==Build Errors==
| + | |
| − | | + | |
| − | If building on one of the x64 variants of Windows (XP, Vista, Win7) and using the x64 variants of Python, you may get python-related errors while linking freeorionca '''error LNK2001: unresolved external symbol'''. This is due to [http://lists.boost.org/Archives/boost/2008/09/142776.php missing symbols] (in Python 2.5.2, 2.5.4 and 2.6.1, possibly others) in the x64 lib. To fix this issue use a 32-bit version of Python instead.
