Use FlightGear.sln to compile fgfs executable for Win32 or x64 architectures with Visual Studio 2008. Previous versions of Visual Studio are not officially supported anymore. Precompiled librairies and headers for compiling x64 executables with VS2008 : ftp://ftp.ihg.uni-duisburg.de/FlightGear/Win32/MSVC/fgfs-x64-VS90-3rdParty+OSG-20100501.zip Precompiled librairies and headers for compiling Win32 executables with VS2008 : ftp://ftp.ihg.uni-duisburg.de/FlightGear/Win32/MSVC/fgfs-win32-VS90-3rdParty+OSG-20100501.zip The VS2008 / v9.0 project files assume the directory layout below : Win32 build : * any_directory_on_any_drive / 3rdParty / ( includes plib, fltk, zlib, libpng, libjpeg, libtiff, freetype, libsvn, gdal, ... bin / include / lib / boost_1_39_0 / boost / source / ( Flightgear CVS directory - It can also be renamed FlightGear or anything else src / projects / VC90 / Win32 / ( generated at build time Debug / ( Debug executable Release / ( Release executable FlightGear.sln ( Main solution utils / install / msvc90 / OpenSceneGraph / ( OSG CMake install bin / include / lib / SimGear / ( SimGear CVS directory simgear / projects / VC90 / 3rdParty, boost_1_39_0 and install/msvc90 are included in the Win32 3rdParty archive. x64 build : * any_directory_on_any_drive / 3rdParty.x64 / ( includes plib, fltk, zlib, libpng, libjpeg, libtiff, freetype, ... bin / include / lib / boost_1_39_0 / boost / source / ( Flightgear CVS directory - It can also be renamed FlightGear or anything else src / projects / VC90 / x64 / ( generated at build time Debug / ( Debug executable Release / ( Release executable FlightGear.sln ( Main solution utils / install / msvc90-64 / OpenSceneGraph / ( OSG CMake install bin / include / lib / SimGear / ( SimGear CVS directory simgear / projects / VC90 / 3rdParty.x64, boost_1_39_0 and install/msvc90-64 are included in the x64 3rdParty archive. Typical setup should decompose into the following steps : 1. Install Visual Studio 2008 Express (http://msdn.microsoft.com/fr-fr/express/aa975050.aspx) 2. Install msysGit (http://code.google.com/p/msysgit/) 3. Create a new directory, say D:\FGFSDevel (or anything else) 4. Unzip precompiled Win32 3rd party archive in it 5. Open a Git Bash session and cd to the new directory ( cd /d/FGFSDevel ) 6. Get SimGear sources from Gitorious : git clone git://gitorious.org/fg/simgear.git SimGear 7. Get FlightGear source from Gitorious : git clone git://gitorious.org/fg/flightgear.git FlightGear 8. Go to D:\FGFSDevel\FlightGear\projects\VC90 and double-click on FlightGear.sln 9. Select the "Release" configuration 10. Open file D:\FGFSDevel\SimGear\simgear\version.h.in and change @VERSION@ into "2.0.0" or any current version 11. Save file as version.h in the same directory 12. Start build (usually F7) 13. Get the data from Gitorious too : git clone git://gitorious.org/fg/fgdata.git fgdata 14. Wait... 15. Add /install/msvc90/OpenSceneGraph/bin and /3rdParty/bin to your PATH environment variable 16. Enjoy - programs are in D:\FGFSDevel\FlightGear\projects\VC90\Win32\Release It is also possible to compile a Debug version. This is only useful when hacking the code because a Debug version is way slower than the Release one. The 64bit build is only available to people having the Professional edition of Visual Studio 2008. In that case, 14. above should be : 14. Add /install/msvc90-64/OpenSceneGraph/bin and /3rdParty.x64/bin to your PATH environment variable When the manual build works, it is possible to start it from the command line. This is useful when setting up a build server or automating the process of retrieving the code and building it in a scheduled task. To do that : 1. open a command line window 2. execute "C:\Program Files\Microsoft Visual Studio 9.0\Common7\Tools\vsvars32.bat" or "C:\Program Files (x86)\Microsoft Visual Studio 9.0\Common7\Tools\vsvars32.bat" in a 64bit environment (Vista 64-bit or Windows7 64-bit) You should see : "Setting environment for using Microsoft Visual Studio 2008 x86 tools." printed in the console 3. cd to the FlightGear project directory : D: cd \FGFSDevel\FlightGear\projects\VC90 (for example) 4. start the build with the command line below : msbuild FlightGear.sln /p:Configuration=Release /m or msbuild FlightGear.sln /p:Configuration=Debug /m That's all...
