[SOLVED] Irrbullet: Help Getting It to work in project

[Oster200]

I am using Visual Studio c++ 2008 and I read that readme.txt file but i feel like i am doing it wrong.

3.1. Add these search directories to your project:
%irrBullet%/source
%irrBullet%/source/bheaders
%irrBullet%/source/bheaders/Bullet

So do i go Tool->Options->Projects and Solutions->VC++ Directories then switch Show Directories for: Include Files?

3.2. add "#include <irrBullet.h>" to the top of your project
with the other includes.

Added that at the top

3.3. add these files to your linker (available in the libs/ folder):
libirrBullet.a, libbulletdynamics.a, libbulletsoftbody.a
libGIMPACTUtils.a (if you use GImpact),
liblinearmath.a, libbulletcollision.a

Make sure the linker files are in that order for irrBullet
or your project will not compile.

Then do I have to go Tool->Options->Projects and Solutions->VC++ Directories then switch Show Directories for: to library?
I think this is wrong because you can only select folders so you cant select them in order.

I know a lot of people here use bullet...I just need to know the steps on how to install.
Do i need the bullet to be installed be for the bullet wrapper?
And where do i put the stuff in first post.

[CuteAlien]

Just to be sure you understood that correct... the "add "#include <irrBullet.h>" to the top of your project" means to the top of your source-file, not to the top of the Include Files Directories (there you add the directory).
And you can change the order of libs after adding them by moving them up-down.
And I suppose you have to add bullet certainly if you want to use it with some wrapper.

Aside from that... you didn't tell which problem you actually have - so no one really knows what you need help with. Any errors?

[zerochen]

ah now i understand what you are trying to do:D

you have to add something like those paths to the lib settings:

F:\Irrlicht\tools\irrBullet\lib\win32_visualstudio\2008
F:\Bullet\lib

then you have to add the libs explicit here:
right click on your project -> properties -> linker -> input

[Oster200]

then you have to add the libs explicit here:
right click on your project -> properties -> linker -> input

That are these lib right? libirrBullet.a, libbulletdynamics.a, libbulletsoftbody.a
libGIMPACTUtils.a (if you use GImpact),
liblinearmath.a, libbulletcollision.a

If so why do they have an .a after them do i out them in with out the lib infront and without the .a after so it would be like this irrBullet.lib for example?

and this is where i write it right?

[zerochen]

yeah this is the right place.
.a are for linux
.lib for windows

so i think you have to change the names to *.lib and enter they in the box in the right order

thats my include order: (names may be different)
BulletMultiThreaded.lib
BulletCollision.lib
BulletDynamics.lib
BulletSoftBody.lib
LinearMath.lib

Well this is what i got for errors
i copied the helloworld from the irrbullet project

just now:

Code: Select all

[CuteAlien]

You haven't added the directory where irrBullet.h can be found to the include directories then.

[Oster200]

Where would irrbullet.h be?

[zerochen]

in your irrbullet source folder of course
like you wrote in 3.1

[Oster200]

Well I now have several linking errors *sigh*.
I just copied the code in irrbullet helloworld.

[zerochen]

you have to add both cpp files to the project (helloworldexample.cpp and exampleframework.cpp)

[Oster200]

Thankyou zerochen it is working you are amazing

and we cant forget you, CuteAlien.

[Nash94]

did yo rename all the .a files to .lib? Im using VS10 and i get "Unable to start program irrBullet.lib The specificed file is an unrecognized or unsupported binary format" error

[zerochen]

hi,

you cant rename the files. you have to recompile bullet and then you get the .lib files (if you are on windows)

.a = linux lib files
.lib = windows lib files
