Box2D under ubuntu 9.10

I've upgraded to 9.10 and am having a problem building the box2D module!

I get the error:

" conflicting declaration 'BBObject *joint' "

in line 227 of 'glue.cpp'

Installing BMax to 9.10 did involve some changes to other source files, I followed the instructions in the Linux Sub-Forum to get it to work. Is this related to my problem with Box2D?

Any advice greatly appreciated as cpp code is a mystery to me.

Hi.

My version of the box2d module has this at line 227 :

	void bmx_b2shape_setrestitution(b2Shape * shape, float32 restitution);

What version are you using? 1.03 ?

I should probably do a release, as I believe that the current version in SVN should be okay to build against the latest GCC.

Yeah, I'm using 1.03...

glue.cpp reads:

void bmx_b2joint_attachobject(b2Joint * joint, BBObject *joint);

at line 227. I just downloaded what I saw on googlecode.

Thanks for the module, by the way. I've been having fun with it.

I've just released 1.04, which should (hopefully) solve your build issues.

Summary of changes since 1.03 :

* Updated to box2d svn (rev 207)
* Added b2LineJoint type.
* Added b2ShapeDef.SetUserData() method.
* Added b2Mat22.GetAngle() method.
* Added b2Mat22 Create... methods, and others.
* Added shape SetFriction() and SetRestitution() methods.
* Fixed contact filter example and docs.
* Added b2EdgeShape type.
* Added staticedges, dynamicedges, pyramidstaticedges and buoyancy examples.
* Added buoyancy types + methods.
* Added b2Body SetMass() method.
* Added b2BodyDef GetMassData() method.
* Converted bool handling in glue to use ints instead.

There's lots of cool new stuff there, and a few more examples.

Have fun :-)

That works now, thanks! And thanks for the update in general.

Feels like I have a fully-functioning linux machine now :)
