Importing to Creator help (- specifically Using Box2D with Qt Creator (2.0))

[Dynite]

Hi,

I've been trying to follow the instructions here: http://labs.trolltech.com/blogs/2010...box2d-is-easy/
But I'm having a whole load of problems.

Firstly my path and sdk etc were all messed up.

So finally I was able to build Box2D and run the testbed via MSVC2005.
Then I tried to import Box2D.h and seemed to have a lot of import problems. (headers, including existing, c:\box2d\..... didn't seem to work)

Eventually I copied the Box2.d and other folders to my project folder and things started to be found.

However once I'd finally changed the source so it compiled (the blog's tutorial seems to be out of date) then I had lots of linker errors about couldn't find _ZSDSomeFunction... etc..

Can someone explain what I should be doing in noob friendly steps please? Smiley

How does your project file look like?

[Dynite]

I literally just did "New Project, Qt Gui Project" So whatever the default is.

I am willing to start from scratch so If you just created a new qt gui project then tried to import, compile and link the Box2D stuff as an idiot's guide that would be very very helpful!

I was wondering whether I've got a compiler mismatch. I.e building Box2d with msvc and qt with mingw.

Is Box2D a library?

[Dynite]

yes - http://code.google.com/p/box2d/

I'm using Version : Box2D_v2.1.2.zip Box2D Release 2.1.2 Featured

If it's a library then you should let qmake know about it

So I need to add something like this?

LIBS += -Lc:\Box2d\Box2d\debug\ -lBox2d

where the L defines path and l defines .lib file ?

Does compiler of library matter? I.e.

MSVC library linking to Mingw Qt project?

Compiler should not matter, but probably it's better to use the same compiler for everything.
