Introduction

Because I saw lots of people on the forums and had a hard time compiling OgreODE myself I decided to write a quick howto on compiling OgreOde with Code::Blocks 1.4.7 on Windows XP [size_t error on Windows Vista? I'm going to check it] with a prebuilt OgreSDK Eihort 1.4.7 (though it should work similar with the sources) to go for the totally free way of 3D game programming
This howto is based on the current (April 27, 2008) versions of the software with OgreODE still trying to use the obsolete STLport. I hope it helps.

OgreOde_core and OgreOde_prefab

To compile the OgreOde_core and OgreOde_prefab:

• Install OgreSDKSetup1.4.7_CBMingW.exe
• Get ogreaddons\ogreode via SVN and put it into $(OGRE_HOME)\ogreaddons\ogreode
• Download ode-0.9 binaries (ode-win32-0.9.zip) from the ODE website
• Unzip them to ogreaddons\ogreode and rename the resulting ode-0.9 folder to ode - you should now have a folder $(OGRE_HOME)\ogreaddons\ogreode\ode
• Open ogreaddons\ogreode\scripts\CodeBlocks\OgreOde_SDK.workspace, ignore the messages about the missing demos and the message about the missing ode_SDK.cbp - we don't need to compile that ourselves because we've got the pre-compiled release
• We need to throw out the STL Port. Change the following in the project's properties:

Linker settings -> Link libraries:
   Delete stlportstlg.5.0 or stlport.5.0

 Search directories -> Compiler:
   Delete $(OGRE_HOME)\stlport\stlport
   Add $(OGRE_HOME)\ogreaddons\ogreode\include

 Search directories -> Linker:
   Change ..\..\ode\lib\Release to ..\..\ode\lib\DebugDLL or ..\..\ode\lib\ReleaseDLL

 
(The changes are the same for prefab, just there's no need to change the linker's search directories)

• In $(OGRE_HOME)\include rename the ode folder to something else - we don't want that one to be used
• In OgreOdeGeometry.cpp [line 903] change the line

dGeomTriMeshDataBuildSimple(_data,(const dReal*)_vertices, (int)vertex_count, _indices, (int)index_count);

to

dGeomTriMeshDataBuildSimple(_data,(const dReal*)_vertices, (int)vertex_count, (dTriIndex*)_indices, (int)index_count);

 
Thanks to rewb0rn for that hint!

• Add all c++ files from ogreaddons\ogreode\src and all from ogreaddons\ogreode\include to the OgreOde_Core project in Code::Blocks
• Compile! After the linking Code::Blocks might throw an error because of the post compile copy script. Ignore that and
• copy the output DLL from ogreaddons\ogreode\lib\Release (and later ogreaddons\ogreode\prefab\lib\Release) to $(OGRE_HOME)\bin\Release by hand
• Compile TinyXML, change paths in OgreOde_prefab and compile that one too

OgreOde_loader

To compile the OgreOde_loader:

• Import the VC++ project from ogreaddons\ogreode\loader\scripts\VC8 with Code::Blocks (select 'All Files (*.*)' if you can't find it)
• Change the directories, 'debug win32' (or 'release win32') would be just 'debug' (or 'release') these days

Search directories -> Compiler:
   Change $(ODE_HOME)\include to $(OGRE_HOME)\ogreaddons\ogreode\ode\include
   Add $(OGRE_HOME)\ogreaddons\ogreode\loader\include

 Search directories -> Linker:
   $(OGRE_HOME)\lib to $(OGRE_HOME)\bin\Debug or $(OGRE_HOME)\bin\Release

• Compile and copy the dll from ogreaddons\ogreode\loader\lib\Debug Win32 (or Release Win32) to $(OGRE_HOME)\bin\debug (or release)

Demos

To compile the demos:

• Remove the stlport wherever you can find it
• Add OgreOde_loader to the project's link libraries
• Add OIS to the linker project's link libraries
• Compile

 
Getting the demos running is a tricky job because you need to provide Ogre's as well as OgreODE's media directory. Give it a try or take a look at the forum thread.

Conclusion

If you experience any linking problems try adding OGREODEEXPORT_LOADER to the compiler defines. Because the post compile copy scripts didn't work for me I couldn't run the demos without changing resources.cfg, maybe someone can figure out what's wrong there. I'm gonna take a coffee break
