How to run CEGUI with Irrlicht

[dehseth]

I am having troubles with compiling my code. I just compiled static libraries of CEGUI and Irrlicht Renderer libs...

And I referenced the scr/include folder to my project. And I include header CEGUI.h... But it's not enough.... IrrlichtRenderer is not visible to my project:

Code: Select all

CEGUI::IrrlichtRenderer* myRenderer = new CEGUI::IrrlichtRenderer(g_device, true );

I also tried to add this path include\RendererModules\Irrlicht to my code and it says this function gets only one parameter (irrlicht device reference)....

So I decided to ask you guys, should I manually add this folder and IrrlichtRenderer header file or is there any other way (like defining a IRRLICHT_RENDERER)? And may you show me a working demo code which contains latest CEGUI and Irrlicht 1.7.1?

Thank you ......

CEGUI.h doesn't include renderer modules. You need to include "RendererModules/Irrlicht/CEGUIIrrlichtRenderer.h". You don't need to add it to path. But you probably will need to add irrlicht includes to path.

[dehseth]

ok I have added these two:

Code: Select all

#include <CEGUI.h>
#include <CEGUIIrrlichtRenderer.h>

#pragma comment(lib, "CEGUIBase_Static_d.lib")
#pragma comment(lib, "CEGUIIrrlichtRenderer_Static_d.lib")

CEGUI::IrrlichtRenderer& g_guiRenderer = CEGUI::IrrlichtRenderer::bootstrapSystem(*g_device);


And now I have other problems:

Error 7 error LNK2019: unresolved external symbol "__declspec(dllimport) public: void __thiscall CEGUI::System::renderGUI(void)" (__imp_?renderGUI@System@CEGUI@@QAEXXZ) referenced in function "public: void __thiscall CChessGame::Run(class irr::scene::ICameraSceneNode *)" (?Run@CChessGame@@QAEXPAVICameraSceneNode@scene@irr@@@Z) ChessGame.obj

Error 8 error LNK2019: unresolved external symbol "__declspec(dllimport) public: static class CEGUI::System & __cdecl CEGUI::System::getSingleton(void)" (__imp_?getSingleton@System@CEGUI@@SAAAV12@XZ) referenced in function "public: void __thiscall CChessGame::Run(class irr::scene::ICameraSceneNode *)" (?Run@CChessGame@@QAEXPAVICameraSceneNode@scene@irr@@@Z) ChessGame.obj

So smt is missing right? What should I include to get rid of these errors??


2. And I want to use static library, not DLL...... so I tried this but didn't work out:

Code: Select all

#define CEGUI_STATIC

Looks like you're not linking to the render module perhaps? You need to link to both CEGUIBase and whichever module you use.

Edit: I'm a moron. I didn't notice the pragma for libs. Nevermind me.

[Kulik]

Something is wrong because static libraries don't use the __declspec(dllimport)/dllexport. Try to define CEGUI_STATIC before you include any CEGUI include files.

I must say I don't work with static CEGUI, so I am not sure...

[dehseth]

well ok let's not use static linking for now..

but cannot run cegui with dll's either. source code compiles with no error but when I try to run it i get this:

Unhandled exception at 0x7c812afb in ChessterD.exe: Microsoft C++ exception: CEGUI::GenericException at memory location 0x0012e310..

this is two lines of code, app crashes at first line:

Code: Select all

CEGUI::IrrlichtRenderer& myRenderer = CEGUI::IrrlichtRenderer::create(*g_device);
   CEGUI::System::create(myRenderer);

I also tried this:

Code: Select all

CEGUI::IrrlichtRenderer& g_guiRenderer = CEGUI::IrrlichtRenderer::bootstrapSystem(*g_device);

any ideas? any body using irrlicht? any example code??


I figured out the problem, I needed this DLL: CEGUIExpatParser_d.dll.. Just copied this to run dir and it finally worked

Just for reference, but I noticed the exception message you posted is the standard windows error handler; this provides no insight into the reason the exception was thrown. If you wrap try/catch around CEGUI code you can display the actual error message; which in this case would have told you the missing module name. Also, CEGUI exception messages can generally be found in the CEGUI.log file.

I use vc8 with CEGUI 0.7.1 and Irrlicht 1.7.1. It works fine. All my issues have been related to my environment setting up the vc8 includes/libs/dlls properly for "release" and "debug" including building CEGUI properly from soruce for "release" and "debug". The code for bootstrap approach I use which works fine is:

IrrlichtDevice* device;

device = createDevice( m_DeviceType, windowSize, bits, fullscreen, stencilbuffer, vsync, 0);

CEGUI::IrrlichtRenderer& m_myRenderer = CEGUI::IrrlichtRenderer::bootstrapSystem( *device );

All the best.
