Has anyone successfully compiled OgreNewt (and a project with it) on Linux? If so, how?
Even getting to the point where OgreNewt compiled on my system wasn't exactly trivial and that just led me to the "undefined reference" errors that others have posted about for over a year.
To start off, I grabbed OgreNewt from the svn (identifies as 2.1.0):
http://svn.ogre3d.org/svnroot/ogreaddon ... t/newton20
And the latest *compiled* Newton library for linux from the Newton site:
http://www.newtondynamics.com/downloads ... .29.tar.gz
That's version 2.29, though, and is thoroughly incompatible with OgreNewt from the svn.
I then grabbed the latest Newton source:
http://newton-dynamics.googlecode.com/f ... s-2.33.rar
Nicely packed in a rar, showing the love (*cough*) for Linux users right off.
The Newton source from the rar contains several flaws for the 32bit linux version, at least, from paths missing a "project" to unsupported (in gcc 4+) typecasting -- and an undefined _ASSERT. The fixes were relatively straightforward, though (hint static_cast), and I finally managed to get Newton to compile. Note that it identifies itself as 2.31 not 2.33 in Newton.h.
Okay... so finally having a compatible version of Newton, OgreNewt from the svn compiled.
However, trying to compile a blank OgreNewt project results in the aforementioned "undefined reference" errors:
The blank OgreNewt project initially complained of multiple missing header files that the OgreNewt installation had not copied to the include directory (specifically OgreNewt_ConvexCast.h, OgreNewt_RayCastVehicle.h, and OgreNewt_stdafx.h). That was easily remedied, though, by copying those 3 header files to the OgreNewt include library to join their brethren.
That's pretty much how I got as far as I did (I wasn't taking notes, so I might've left out something, like adding OgreNewt to configure.ac). But has anyone gotten to the point where it actually works?
