Cannot open include file irrlicht

RockViper · Post by **RockViper** » Mon Jul 07, 2008 7:59 pm

I need some help. I have been trying to build a sollution, the project is the simple hello world irrlicht app. I cannot get the solution to compile without the error:

fatal error C1083: Cannot open include file: 'irrlicht': No such file or directory

Ok, so I know how to set my include and lib directories, and I did that from the start. I even pointed to two directories each having a copy of irrlicht.h. I have checked them and rechecked them and they are correct but VC++2008 still says cannot find irrlicht.h header file.

Im eager to get started with Irrlicht. I was checking out ogre, which I was able to compile with no errors the first time I compiled, but the examples that come with it are VERY SLOW(often 4 to 2 fps). So I tried Irrlicht and WOW, the speed diffference is amazing(1000 fps on one demo, 100fps on multianimation demo with 65 animated characters on screan)! I wanna get started now!

Somebody tell me what Im doin wrong please, thank you.

Heres a pic to help you in giving me advice

try to include "irrlicht.h" instead of "irrlicht"

Thanks for the advice but I've already tried that. In Visual Studio 8 you don't put .h after header files, you just use #include <irrlicht>. Using #include <irrlicht.h> gives 69 errors. Its wierd, I have checked everything, #include <irrlicht> is the correct way to include, thats how i included header files with the ogre sdk and never had a problem.

Im sorry I mean Visual Studio 9, which is Visual Studio 2008

In my projects in 2008, I always use #include <irrlicht.h>. Just to check, I went and changed it to #include <irrlicht>, and I got the fatal file doesn't exist error. Add the .h and post the errors you get; they are probably unrelated.

69 nine errors is a progress compared to "can't find irrlich.h"
Tell us first of 69 and lets get starting.

Thanks for the help. Im not sure about the <.h> being required, I believe you it's just that I remember while trying to compile some code from the book Sams Teach Yourself C++ in 24 hours(source written for VC++6) and the code wouldnt compile, seems like the solution was a combination of dropping <.h> from header files and also using, using namespace std;. I would love it if you would say, "I told you so" pointing out a solution and help me compile the code

Below is the source im trying to compile and following that are the errors generated when I try to build the solution.

Code: Select all


#include <irrlicht.h>

using namepsace irr;
using namepsace core;
using namepsace scene;
using namepsace video;
using namepsace io;
using namepsace gui;

int main()
{
	IrrlichtDevice *device =
		createDevice(EDT_SOFTWARE, dimension2d<s32>(512, 384), 16,
			false, false, false, 0);

	device->setWindowCaption(L"Hey BItches! - 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("../media/sydney.md2");
	IAnimatedMeshSceneNode* node = smgr->addAnimatedMeshSceneNode( mesh );

	if (node)
	{
		node->setMaterialFlag(EMF_LIGHTING, false);
		node->setFrameLoop(0, 310);	
		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;

I tried looking up where I found the info about dropping the <.h> from header files in VS9 but all I could find was this youtube video showing a simple tutorial that uses #include <header> instead of #include <header.h>

http://www.youtube.com/watch?v=9CfnN98UK5g

and another showing the include without .h

http://www.metacafe.com/watch/1257193/v ... _lesson_1/

Thanks for helping me get this solved. Just justifing my reasoning behind dropping the .h.

night_hawk · Post by **night_hawk** » Mon Jul 07, 2008 9:13 pm

The "without .h" thingy is for standardized headers

iostream, fstream, vector, map are examples of headers that used to have .h at their ending in older times, but now are used without. Why? No idea

Ion Dune · Post by **Ion Dune** » Mon Jul 07, 2008 9:13 pm

namespace is misspelled in all of those (namepsace). If you fix that, it should work.

Also, what you must have been thinking of is #include <iostream>, you don't use a .h there, and you also use the namespace std.

RockViper · Post by **RockViper** » Mon Jul 07, 2008 9:25 pm

Excuse the language in the code, Its not directed to you guys, it was an attempt at humor, didn't think anyone was gonna see the code

I knew it was some dumb mistake I made lol, thanks guys, awesome help. Can you believe I didn't notice the mispelling of namespace lol, or the fact that it must be mispelled because it was not highlighted as a keyword lol. Im embarrassed but greatful

If ya don't mind, I did as you said and now I am left with only 2 errors, help me out please.

Here comes the source, then the errors.

Code: Select all


#include <irrlicht.h>

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

int main()
{
	IrrlichtDevice *device =
		createDevice(EDT_SOFTWARE, dimension2d<s32>(512, 384), 16,
			false, false, false, 0);

	device->setWindowCaption(L"Hey BItches! - 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("../media/sydney.md2");
	IAnimatedMeshSceneNode* node = smgr->addAnimatedMeshSceneNode( mesh );

	if (node)
	{
		node->setMaterialFlag(EMF_LIGHTING, false);
		node->setFrameLoop(0, 310);	
		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;

I think I figured it out. I had omitted the line #pragma comment(lib, "Irrlicht.lib") while trying to figure out what I was doing wrong, read somewhere that you shouldnt do it like that, anyways. Thanks for you help, very fast response

I would like to recomend some awesome books for you guys.

Wordware - Programming Game AI By Example
AI Game Engine Programming

I think I like AI Game Engine Programming a little better because it seems "deeper" in its knowledge. It touches on the psychology aspect of programming AI engines, very good stuff. I recomend both.

Thanks again!

How's a borg supposed to have some fun when this forum is infested with people who actually want to help?
