Hello World error

[Galhad]

Hi, i tried to make Irrlicht's Hello World application. It compiles without any errors, but when i run program it close automaticly. I run debugger and it show error:Your program reported an access violation (segmentation error). I use Dev-c++ and here is the code:

Code: Select all

#include <irrlicht.h>
 using namespace irr;

 int main()
 {
        // start up the engine
        IrrlichtDevice *device = createDevice(video::EDT_DIRECT3D8,
                core::dimension2d<u32>(640,480));

        video::IVideoDriver* driver = device->getVideoDriver();
        scene::ISceneManager* scenemgr = device->getSceneManager();

        device->setWindowCaption(L"Hello World!");


        // add a first person shooter style user controlled camera
        scenemgr->addCameraSceneNodeFPS();

        // draw everything
        while(device->run() && driver)
        {
                driver->beginScene(true, true, video::SColor(255,0,0,255));
                scenemgr->drawAll();
                driver->endScene();
        }

        // delete device
        device->drop();
        return 0;
 }

Please help.

I can't see any problems with the code.
Maybe you used the wrong DLL (the one for MSVC rather than gcc).

I suggest to get another IDE anyway, since Dev C++ is not supported anymore because it is ancient. Better get Code Blocks or Eclipse.

How can I see what DLL i used? I compiled first example and it works. i copied code to my project, compile it and i've got this same error. I add ibIrrlicht.a.

You should use the one in bin/Win32-gcc/.

Now I downloaded Code Block. And still have this same problem. Example works, but this code in other project not. Can you explain how use this DLL?

You just put the dll to the same folder as exe

[randomMesh]

Can you explain how use this DLL?

If you run your executable from the examples directory (bin/Win32-VisualStudio/), it would use the DLL inside, which is the one for MSVC. And because you used libIrrlicht.a, which is for gcc, this can not work.

Easiest way is to make a new folder, copy your executable and the DLL from bin/Win32-gcc/ to it and that's it. Just make sure you don't have a wrong Irrlicht DLL in windows/system32 or something.

I copy my executable, 01.HelloWorld (example) and dll. And it doesnt work. My executable and example. Earlier i compiled that example and in Win32-gcc folder it run normally.
EDIT I change build folder to Win32-gcc, compiled new project with this same code and now its works Thanks
