I'm using Irrlicht 1.4.2, newton 1.53, and Iphysics 1.2. Is there a more recent version? I can't find one.
You're not linking to the proper libraries.

I kind of guessed at linking. There is no documentation at all about newton linking, and there are multiple link folders.

The newton libs are linked correctly. The IPhysics libs aren't.
Software documentation is like sex. If it's good you want more. If it's bad it's better than nothing.

it also could be the order of the libs !!!
I link first to libNewton.a and after that to libIPhysics.a and it works !!!
If I link first to IPhysics then I'll get linker errors... :lol:

I guess I don't understand how to link properly under Visual Studio. I went Tools->Options and added new include and lib directories. That worked for Irrlicht, so I assumed it would work for IPhysics. How do I do it?

just adding the directories is not enough...
did you also link against the IPhysics and Newton libs ???
for VS it is usually a pragma statement at the beginning of the main.cpp (like the one for Irrlicht.lib)... ;)
so it should look something like this:

Code: Select all

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

I'm now getting this:

Code: Select all

1>IPhysics.lib(CPhysics.obj) : MSIL .netmodule or module compiled with /GL found; restarting link with /LTCG; add /LTCG to the link command line to improve linker performance
1>LINK : warning LNK4098: defaultlib 'MSVCRT' conflicts with use of other libs; use /NODEFAULTLIB:library
1>main.obj : error LNK2001: unresolved external symbol "class irr::IrrlichtDevice * __cdecl irr::createDevice(enum irr::video::E_DRIVER_TYPE,class irr::core::dimension2d<int> const &,unsigned int,bool,bool,bool,class irr::IEventReceiver *,char const *)" (?createDevice@irr@@YAPAVIrrlichtDevice@1@W4E_DRIVER_TYPE@video@1@ABV?$dimension2d@H@core@1@I_N22PAVIEventReceiver@1@PBD@Z)
1>C:\Documents and Settings\Killian\My Documents\Visual Studio 2008\Projects\testing\Debug\irrlicht_test.exe : fatal error LNK1120: 1 unresolved externals
Does this mean I need an older version of Irrlicht?
