Irrlicht LNK2019: unresolved external symbol __imp__createDevice referenced in function _main

I am trying to build the example 01.HelloWorld" of Irrlicht using VS 2010. When I do I get the error:

LNK2019: unresolved external symbol __imp__createDevice referenced in function _main

I found a possible solution for this problem, and tried to apply some solutions in the answer, by changing int main to int _tmain(int argc, _TCHAR* argv[]) and int _tmain() but it didn't work.

#include <irrlicht.h>

using namespace irr;

using namespace core;
using namespace scene;
using namespace video;
using namespace io;
using namespace gui;

#ifdef _IRR_WINDOWS_
#pragma comment(lib, "Irrlicht.lib")
#pragma comment(linker, "/subsystem:windows /ENTRY:mainCRTStartup")
#endif
#include <tchar.h>

int main()
{
    IrrlichtDevice *device =
        createDevice( video::EDT_SOFTWARE, dimension2d<u32>(640, 480), 16,
            false, false, false, 0);

    if (!device)
        return 1;

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

    IVideoDriver* driver = device->getVideoDriver();
    ISceneManager* smgr = device->getSceneManager();
    IGUIEnvironment* guienv = device->getGUIEnvironment();

    guienv->addStaticText(L"Hello World! This is the Irrlicht Software renderer!",
        rect<s32>(10,10,260,22), true);

    IAnimatedMesh* mesh = smgr->getMesh("../../media/sydney.md2");
    if (!mesh)
    {
        device->drop();
        return 1;
    }
    IAnimatedMeshSceneNode* node = smgr->addAnimatedMeshSceneNode( mesh );

    if (node)
    {
        node->setMaterialFlag(EMF_LIGHTING, false);
        node->setMD2Animation(scene::EMAT_STAND);
        node->setMaterialTexture( 0, driver->getTexture("../../media/sydney.bmp") );
    }

    smgr->addCameraSceneNode(0, vector3df(0,30,-40), vector3df(0,5,0));

    while(device->run())
    {
        driver->beginScene(true, true, SColor(255,100,101,140));

        smgr->drawAll();
        guienv->drawAll();

        driver->endScene();
    }

    device->drop();
    return 0;
}

What fixed this for me was adding

#ifdef _MSC_VER
#pragma comment(lib, "Irrlicht.lib")
#endif

Just on what you've provided, there are three likely solutions:

  1. You didn't add lib/VisualStudio to your additional linker directories.

  2. IrrLicht.dll is missing from the project directory.

  3. The code is looking for _main(), not main(), and not _tmain(). Try changing int main() to int _main().

This probably won't work, but it's the best I can do working on what I've got.
