Error while intialising CEGUI with SFML

[arkdemon]

Hello eveyrone. I am new to CEGUI and this forum. I use SFML and I tried to use CEGUI with it. However, the program crashes at:

Code: Select all

CEGUI::OpenGLRenderer::bootstrapSystem();

or

Code: Select all

CEGUI::System::create(*renderer);

It is the first time I use CEGUI. I compiled it successfully, I can run the demos but I can t make my program run. My code is just this:

Code: Select all

#include <GL/glew.h>
#include <SFML/Window.hpp>
#include <SFML/Graphics.hpp>
#include <CEGUI/RendererModules/OpenGL/GL3Renderer.h>
#include <CEGUI/RendererModules/OpenGL/GLRenderer.h>

int main()
{
  sf::ContextSettings sets(4,4,4,3,3);//Initialize the window
  sf::RenderWindow screen(sf::VideoMode(640, 480), "Hello CEGUI!",sf::Style::Default, sets);
  screen.setVerticalSyncEnabled(true);

  glewExperimental = GL_TRUE;//Initialize GLEW
  GLenum err = glewInit();
  if(err !=  GLEW_OK){
      printf("%s\n", glewGetErrorString(err));
  }
  if(!GLEW_VERSION_3_3){
      printf("OpenGL Version too low\n");
  }

  CEGUI::OpenGLRenderer *myRenderer = &CEGUI::OpenGLRenderer::create();//Initialize CEGUI
  CEGUI::System::create(*myRenderer);//<-- Crashes

  return 0;
}


I do not understand at all.
If someone could help me, i would be very happy and if you need more info, please ask.
Thank you

PS: there are no logs

"Crashes"? More info required. If there are no logs then you need to tell us your OS, your CEGUI version and your SMFL version and whateveer else could be relevant. Also why don't u tell us how it "crashes"? I am sure you get an exception or MAV and we need to know where. We release all our psychics from the cages last year so we do not have the power to magically know these things anymore.

Also did you look at this? viewtopic.php?f=2&t=6656

Thank you for answering.
Sorry but the program crashes even before the render function. It crashes on the initialization.
My OS is Windows. I compile with Mingw 4.8.1 and my IDE is Qt Creator and I use CEGUI 0.8.3 and SFML 2.1.
When the window opens, the program crashes: the screen is white and a message appears with written: CEGUI.exe has stopped working. Windows is checking for a solution.
I stripped everything from the code except the initialization process so the code I gave you has no render function but just the initialization. Even if I try the stripped version it crashes at:

Code: Select all

CEGUI::System::create(*myRenderer);

or the boostrapSystem method.
I hope I am clearer.

[Ident]

No you are not clearer. Does your development environment not allow you to debug? you should start in debugging mode and see HOW it crashes.

I have no experience with your setup so there is no way i can help you other than you telling me how it crashes and in what code line.
Also did you look at the link i provided?

[arkdemon]

Yes I debuuged and it said it crashed at

Code: Select all

CEGUI::System::create(*myRenderer);

I posted the code earlier:

Code: Select all

#include <GL/glew.h>
#include <SFML/Window.hpp>
#include <SFML/Graphics.hpp>
#include <CEGUI/RendererModules/OpenGL/GL3Renderer.h>
#include <CEGUI/RendererModules/OpenGL/GLRenderer.h>
#include <CEGUI/System.h>

int main()
{
  sf::ContextSettings sets(4,4,4,3,3);//Initialize the window
  sf::RenderWindow screen(sf::VideoMode(640, 480), "Hello CEGUI!",sf::Style::Default, sets);
  screen.setVerticalSyncEnabled(true);

  glewExperimental = GL_TRUE;//Initialize GLEW
  GLenum err = glewInit();
  if(err !=  GLEW_OK){
      printf("%s\n", glewGetErrorString(err));
  }
  if(!GLEW_VERSION_3_3){
      printf("OpenGL Version too low\n");
  }

  CEGUI::OpenGLRenderer *myRenderer = &CEGUI::OpenGLRenderer::create();//Initialize CEGUI
  CEGUI::System::create(*myRenderer);//<-- Crashes

  return 0;
}

and it crashes at

Code: Select all

  CEGUI::System::create(*myRenderer);//<-- Crashes}

here are the libs I link:
libCEGUIOpenGLRenderer-0.a and libCEGUIBase-0.a

EDIT: yes I looked at the link but that is in the rendering process not at the initialization process which is where I am.

I can only repeat myself in a hopefully clearer way: You need to debug into CEGUI. Did you build and link CEGUI in debug mode? You should be able to debug inside the CEGUI library then, unless your compiler and toolset doesn't allow you this which means that it is total trash and not usable for any sort of serious development. I need to know where it crashes INSIDE CEGUI not INSIDE YOUR OWN CODE otherwise it is absolutely impossible to tell what could cause the problem, I can only guess. You see, I cannot reconstruct your crash from my side. So how should i know what is wrong.

[arkdemon]

Oh ok. Sorry I did not understand. I am currently recompiling CEGUI and I will tell you the results.
Thank you for trying to help me.

[arkdemon]

It does not seem to work when I compile: it can not find "-lDbgHelp" when building libCEGUIBase-0_d.dll.a

[Ident]

No idea. Try to google for the error to find out what it means.
