Help with tutorial 1, dll not found

[Guest]

OK, I was trying the "Hello World" tutorial... now don't you dare to laugh I get no errors while compiling the code, but an error message that basically says "Irrlicht.dll not found" (My winXP isn't english). I use Visual C++ 6.0 and I just started with C++. I know some basic programming with VB and Java. What does "#pragma comment(lib, "Irrlicht.lib")" do? Can't I do it "manually" or something? Since the dll can't be found.

This is my code:

Code: Select all

#include <irrlicht.h>
using namespace irr;

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

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

int main()
{
	IrrlichtDevice *device =
		createDevice(EDT_SOFTWARE, dimension2d<s32>(512, 384), 16,
			false, false, false, 0);
	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 engine!",
	 rect<int>(10,10,200,22), true);

	IAnimatedMesh* mesh = smgr->getMesh("C:/Documents and Settings/Carl/Skrivbord/Irrlicht/Kopia av Files/irrlicht-0.9/media/media/sydney.md2");
	IAnimatedMeshSceneNode* node = smgr->addAnimatedMeshSceneNode( mesh );

	if (node)
	{
	node->setMaterialFlag(EMF_LIGHTING, false);
	node->setFrameLoop(0, 310);	
	node->setMaterialTexture( 0, driver->getTexture("C:/Documents and Settings/Carl/Skrivbord/Irrlicht/Kopia av Files/irrlicht-0.9/media/media/sydney.bmp") );
	}

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

	while(device->run())
	{
		driver->beginScene(true, true, SColor(0,200,200,200));

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

		driver->endScene();
	}
	device->drop();
return 0;
}

I think I got it right And I did like it says in the beginning of the tutorial.

We also need the location of irrlicht.lib to be listed, so select the 'Libraries' tab and add the \lib\VisualStudio directory.

IF i skip that, I get this out put:

--------------------Configuration: Cpp1 - Win32 Debug--------------------
Linking...
LINK : fatal error LNK1104: cannot open file "Irrlicht.lib"
Error executing link.exe.

Cpp1.exe - 1 error(s), 0 warning(s)

If I do what I think is the right thing I get:

--------------------Configuration: Cpp1 - Win32 Debug--------------------
Compiling...
Skipping... (no relevant changes detected)
Cpp1.cpp

Cpp1.obj - 0 error(s), 0 warning(s)

BUT... since the dll can't be found, I can't run it
Any foolprof way to link the dll? In the code itself? (to "link" is the right word?) I don't know that much yet, but I really want to. I'm usually good at finding solutions, but this is just annoying

Thanks in advance!

just copy the dll from the bin dierectory into the same directory as the executable or into your system32 directory

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

I think this line instructs the compiler to somehow automatically link irrlicht.lib.

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

I think this line instructs the compiler to somehow automatically link irrlicht.lib.

Thanks a lot. I don't see the model, but thanks. It finds the dll now.

EDIT: I found a misstype, that's why the model didn't show up. I copy and pasted the path, but I did't see that it became "/media/media" instead of just "/media".

yes, the #pragma comment tells the linker to link to that file rather then using the alternative method of setting your library file location in the project options/properties.
