Since the Ogre 1.7 version, CEGUI is not an Ogre dependency anymore using its own basic interface for its samples now instead of CEGUI.

This means that from now on, you have to build CEGUI for your Ogre project yourself, in case you want to use the latest Ogre or CEGUI versions. Otherwise, you can grab the latest precompiled dependencies from Ogre download section and CEGUI download section. __Be careful:__ The current [[04/14/10] precompiled Win32 Ogre (1.7.0) and CEGUI (0.7.1) releases are not compatible. Either compile Ogre or CEGUI yourself to solve this problem.

The recommended approach however is to build CEGUI against the Ogre version you want to use.


Here are all the links you need: For the source it's recommended to get the latest stable branch version from SVN (link leads to CEGUI 0.7 version which is the latest version right now) You can also just download it packed from source code here If the branch version won't work you can try the latest stable snapshot which will most definitely be stable and working.

Additionally you will need dependencies suiting your compiler. Download them for your CEGUI version and unpack the "dependencies" folder into your CEGUI main folder, so that it will co-exist next to the folders "bin", "cegui","datafiles" etc.


Otherwise to obtain the needed source package and dependency package you might wanna check this link on how to obtain libray source for CEGUI.


Step-by-step guide

  • 1. Get the appropriate CEGUI version from the CEGUI download page or get the very latest CEGUI version from the SVN repository (see links and info above).
  • 2. Get the latest Ogre version. If you are compiling it yourself, you will need to build it first to get Ogre's .lib and .dll files ready for CEGUI.
  • 3. In your CEGUI folder there should be a folder called "projects" with a subfolder called "premake". It is recommended to use the custom premake version of CEGUI. Otherwise you can get version 3.6 or 3.7 of premake. Once you have premake extract the premake.exe file into the said folder.
  • 4. Open config.lua in the premake folder and edit the Ogre and OIS paths accordingly, so that they will point to the dependency files. In my case for example the 2 lines look like this (having the OGRE and CEGUI main folders on the same level):
OGRE_PATHS = { "../OGRE", "include/OGRE", "lib" }
OIS_PATHS = { "../OGRE", "include/OIS", "lib" }

Note: Remember to use forward slashes here! Just copying the paths from the Windows explorer will give you backward slashes. Replace them!

Next, set all Renderers you do not need to "false", in this case we will only need OGRE_RENDERER. You can also set all samples to false, except maybe SAMPLES_OGRE if you want to compile those.

Important: Since Ogre 1.7 the "boost" library is a new dependency of OGRE. If you are unsure if your Ogre version needs boost, you might want to check if there is a boost folder in your Ogre main folder. In case your Ogre version makes use of boost, you will additionally add boost to the extra paths of CEGUIOgreRenderer, in my case it looks like this: 

CEGUI_EXTRA_PATHS = { 
{ "../OGRE/boost_1_42", "", "lib", "CEGUIOgreRenderer" }
 }
  • 5. Next, we create our Visual Studio Projects - Execute build_vs2008.bat to create a Visual Studio 2008 project or execute any other .bat file for your respective compiler version.
  • 6. This should create CEGUI.sln in the premake folder. Open it.
  • 7. If you have the Ogre lib files seperated into a Debug and Release folder, you will have to change the path in the Linker settings of the project so they will point to the lib/Debug or lib/Release folder for each configuration respectively.
  • 8. Build the CEGUIOgreRenderer in Debug and Release mode, copy the CEGUIBase and CEGUIOgreRenderer .dll and .lib files as well as the CEGUI include folder and there you go, you're done!

Questions

For any suggestions and questions send a PM to me (Ident) or just ask in the forums and someone else will help you for sure... In case you need help building Ogre, I'd recommend reading for example short guide.
