Help with IPhysics

Hi,
I can't compile my project using IPhysics.
The problem is when linking.
The message that appears is:

.objs\main.o:main.cpp:(.text+0x13e): undefined reference to `CPhysics::CPhysics()'
.objs\main.o:main.cpp:(.text+0x167): undefined reference to `CPhysics::init(irr::ITimer*)'
.objs\main.o:main.cpp:(.text+0x28d): undefined reference to `CPhysics::addEntity(SPhysicsCube*)'
.objs\main.o:main.cpp:(.text+0x3fe): undefined reference to `CPhysics::addEntity(SPhysicsCube*)'
.objs\main.o:main.cpp:(.text+0x492): undefined reference to `CPhysics::update()'
.objs\main.o:main.cpp:(.text+0x502): undefined reference to `CPhysics::~CPhysics()'
.objs\main.o:main.cpp:(.text+0x529): undefined reference to `CPhysics::~CPhysics()'
collect2: ld returned 1 exit status

Can anyone help?

looks like you didn't add the IPhysics files to your project

What do you mean by adding the IPhysics files to my project?
Do you mean including them? I've done that.
I've linked both Newton.lib and IPhysics.lib and included both.

~If your using Dev C++

Are the include folder files in the compilers include folder or not? If not you have to include them manually with Project Options->Directories->Include Directories then add the folder the IPhysics include files are in to it. Also, you may wanna put IPhysics at top, of the included directories list.

No, i'm using code::blocks.
I've included all the IPhysics, Newton and Irrlicht files manually in the project build options.

I also get these linker errors in Dev C++

I have put the include folder in the include section of directories in project options, the library folder in the library section and the .lib in the linker section in parameters.

I've even tried the .a available.

I just tried compiling the example source with all the project options set up, and I get this:

Hi, dwfait,

When you're compiling the project, how long does the linking take?
My project takes 5 minutes to link only! If i dont link with IPhysics, it takes 23 seconds. Why?

Anyway, the error you get, its exactly the same as mine. Does anyone know how to fix this?

dwfait · Post by **dwfait** » Thu Dec 14, 2006 5:51 pm

It's pretty fast compiling / linking for me...always under 5 seconds. Although my program is only a very small test program.

RapchikProgrammer · Post by **RapchikProgrammer** » Thu Dec 14, 2006 6:15 pm

You cant work with .a using iphysics for now, cause the .a file online is v1.1 and the package for iphysics is 1.2 so its gonna cause probs! Only .lib supporting compilers for now!

dwfait · Post by **dwfait** » Thu Dec 14, 2006 6:55 pm

Thanks, but I've been trying it with the .lib aswell and still no worky

dwfait · Post by **dwfait** » Thu Dec 14, 2006 8:12 pm

Is there an old version of IPhysics that works with the .a, or an updated version of the .a somewhere?

monkeycracks · Post by **monkeycracks** » Thu Dec 14, 2006 11:09 pm

I just compiled up a .a for Irrlicht 1.2, IPhysics 1.2, and the latest Newton release(Not sure which one that is).

PM me if ya need it
