Trying to add LUA to my project

[Habba]

I'm trying to get started with LUA and CEGUI (using with Ogre), but so far I have been very unsuccesful. I have tried to follow LUA tutorial found from CEGUI wiki, but it's hopelessly unfinished and undetailed.

Currently I'm getting a linker error saying:
Gui.obj : error LNK2001: unresolved external symbol "__declspec(dllimport) public: virtual class CEGUI::RefPtr<class CEGUI::Event::ConnectionInterface>
__thiscall CEGUI::LuaScriptModule::subscribeEvent(class CEGUI::EventSet *,class CEGUI::String const &,class CEGUI::String const &)" (__imp_?subscribeEvent@LuaScriptModule@CEGUI@@UAE?AV?$RefPtr@VConnectionInterface@Event@CEGUI@@@2@PAVEventSet@2@ABVString@2@1@Z)

I guess that has something to do with my compiler (VC++ 2005) not finding some .lib file, but that's just a guess.

So, I'd like to know what files I need to link, what SDK/etc. to install and paths to add in order to get LUA scripting to work.

I think I have Ogre 1.2, but I'm not so sure about CEGUI version. I tried to update it to 0.5, but I'm not quite sure if it was succesful.

Did you include the CEGUILua.lib or CEGUILua_d.lib file into your project. Error looks like a missing lib file

[Habba]

These are the .lib files I currently have included in my debug-verion. Don't really know if all of them are necessarily needed...

OgreMain_d.lib
CEGUIBase_d.lib
OgreGUIRenderer_d.lib
CEGUILua_d.lib
tolua++_d.lib
lua50_d.lib

It looks like an unsuccessful upgrade. most likely your headers and libraries do not match!

I downloaded Ogre SDK 1.2.4 for Visual Studio 8 (=2005) and Cegui Mk-2 Win32 SDKs 0.5.0b, installed both of them and added thos paths into my project directories, but it really didn't do anything.

So... what now then?

[lindquist]

iirc ogre comes with cegui libs and headers. remove these completely. also make sure you recompile the ogre renderer module!

[Habba]

also make sure you recompile the ogre renderer module!

Do what to what now...?

There is info on this on the Ogre and Cegui wikis/forums, have a search around.

Ogre has a GuiRenderer that uses Cegui, so when you get the Ogre source package it comes with a version of Cegui's libs and headers etc. Basically you need to make sure you are using the same Cegui that Ogre is using.

Right, I'll summary what's going on now:

1. Downloaded CEGUI 0.5b source package for VC8, along side with the needed dependencies
2. Downloaded Ogre 1.2.4 source package for VC8, along side with the needed dependencies
3. Copied the dependencies folder to Ogre/CEGUI source package folders, respectively
4. Opened the Visual Studio 2005 solution file from ...\CEGUI-0.5.0\makefiles\premake
5. Compiled the solution under Release and Debug settings
6. Updated OGRE to use the latest CEGUI, by following these instructions.
7. Opened the Visual Studio 2005 solution file from ..../ogrenew
8. Compiled the whole solution under Release settings

Now, I'm not quite sure what's the recommend method after this, should I use this folder as my include/lib directory, or should I copy all .h .dll and .lib files under my Ogre/CEGUI SDK directory. I tried to do both, but neither did work (might be that made mistakes there, since it's getting pretty messy after 4-5 days of constantly compiling, installing, copying and moving files.)

Edit: And the error remains unchanged.

[scriptkid]

It looks like you have followed the steps in the correct order. What is the exact error you are getting now?

Have you tried to get CEGUI and Ogre running without merging them? I mean have you tried to run a cegui sample after compiling, before you copied stuff over to Ogre?

The same for Ogre: did it compile and run before copying new cegui files over? I ask these questions to make sure that both libraries work in their 'pristine' setup.

[EDIT] i had already forgotten the topic Do Ogre and Cegui work together without the Lua part? [/EDIT]

Good luck!

They used to.. but now I see it isn't working anymore. I think I'll remove everything related to Ogre and CEGUI from my computer and reinstall these. Might not be impossible that something got messed up while I tried to update. If you won't hear about me for a while... wait longer, for I'll come back later then. And thanks for support.

By the way, if what I posted is the way to upgrade should be done, I suggest that this information would be put to Wiki, since I had to figure it out myself by Trial & Error.
