undefined reference to irr::createDevice

i'm trying to compile a sample application with irrlicht. I unpacked the zip file and under Eclipse CDT i have set the include and library paths. However, i always get this error:

undefined reference to `irr::createDevice(irr::video::E_DRIVER_TYPE, irr::core::dimension2d<int> const&, unsigned int, bool, bool, bool, irr::IEventReceiver*, char const*)'

I'm using linux ubuntu 8.04.

Any ideias ?

Well it would seem that somehow Eclipse is not finding irrlicht, or at least part of it.

You did include irrlicht.h didn't you? ( #include <irrlicht.h>)

are you trying to compile the first example?

What's the char* you've put as the final parameter of createDevice? It's certainly never been a parameter before version 1.4 of irrlicht (though could be in 1.4, i've not upgraded yet, tut tut).

EDIT: i see what it is now, the version of irrlicht.. but you shouldn't use it so don't specify a parameter for that, though it shouldn't be what's causing the problem...

You'll need to actually link with the Irrlicht library. I'm sure your IDE documentation will tell you how to do that.

He said he's setup the library paths.... but maybe they're wrong or something... does it say anything when linking that it couldn't find the library?

Do you have the pragma comment that the tutorials use for linking?

Well, simply setting the paths need not automatically link the library. You will need a link command somewhere, either via pragma for MSVC, or via a compiler swtich.

Yes, he did say that.

#pragma is implementation (i.e. compiler) dependent.

Does Eclipse understand it?

No, apparently not.

Well, Eclipse is not a compiler, so why should it? If you can use Eclipse with MSVC it should support the pragma stuff.

Heh, fair point. Good luck using MSVC on Ubuntu though.
