Problem with linker

[Sampei120]

When I go to compile a project I see this error

[Linker error] undefined reference to
`_imp___ZN3irr1 2createDeviceEN S_5video13E_DRI VER_TYPEERKNS_4 core11dimension 2dIiEEjbbbPNS_1 4IEventReceiver EPKw'

someone knows how can I do for delete this error???
Thanks

You are missing a function possibly with the name createDevice. Perhaps
the function is just not found by the linker (did you include all the
correct files?), perhaps the parameter types differ between the
prototype/class declaration and the implementation, perhaps the
constness of the function is different. There could be any number of
problems, but we'd need to see some code to figure out what is the
cause of the error.

You need to tell your linker where to find that function. If it is your
function, and you forgot to define it, you need to define it somewhere.

Thank you! This is the code...

#include <irrlicht.h>
using namespace irr;
using namespace core;
using namespace scene;
using namespace video;
using namespace io; // Serve per I/O
using namespace gui;
#pragma comment(lib, "Irrlicht.l ib")

int main()
{
// Creation of device
IrrlichtDevice *device = createDevice(ED T_DIRECTX8,
dimension2d<s32 >(640,480),
// ERROR
16,false,false, false,0);

// Creatio scene manager e GUI
IVideoDriver* driver = device->getVideoDriver ();
IGUIEnvironment * guienv = device->getGUIEnvironm ent();
ISceneManager* smgr=device->getSceneManage r();

// Screen
device->setWindowCapti on(L"Irrlicht 1.1");
guienv->addStaticText( L"Ciao Mondo!", rect<int>(10, 10, 70, 22), false,
true,
0, -1, true);

// mesh 3D
IAnimatedMesh* mesh = smgr->getMesh("earth .x");

// Apply the mesh
IAnimatedMeshSc eneNode* node = smgr->addAnimatedMes hSceneNode(mesh );
node->setScale(vecto r3df(40.0,40.0, 40.0));

// Light
smgr->addLightSceneN ode(0, vector3df(0,100 ,-200),
SColor(0,200,20 0,200), 10000.0f,-1);

// Static Camera
smgr->addCameraScene Node(0, vector3df(0,70,-100),
vector3df(0,10, 0));

// Scene
while (device->run())
{
driver->beginScene(tru e, true, SColor(0,0,0,0) );
smgr->drawAll();
guienv->drawAll();
driver->endScene();
}

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

but I don't miss the function... I think...

Is this library being linked with your project when you compile and link it?
int main()
{
// Creation of device
IrrlichtDevice *device = createDevice(ED T_DIRECTX8, dimension2d<s32 >(640,480),

Here you call a function, that is not defined in the sources you show,
so presumably you must link with the library mentioned above.

Did you check that your lib file "Irrlicht.l ib" is in your default lib
path? If not, I would try adding the path to that library in your
pragma.

#pragma comment(lib, "somepath/Irrlicht.lib")

Sometimes, the order of the linked libraries makes a difference when the
linker should find what is needed...
