Box2D Forums

I am trying to compile the helloworld and testbed box2d projects using the qnx blackberry ide, c++.

I have added the box2d library as a reference in my project so it is finding all the box2d files for importing.

the box2d library is building good for the bb dev alpha simulator.

I am getting the error:
cannot find -lBox2d in helloworld. (problems area in qnx) No line number.

then:
skipping incompatible C:\----------\Box2D\Simulator-Profile\libBox2D.a when searching for -lBox2D
HelloWorld C/C++ Problem


i haven't changed anything on the helloworld or testbed. straight from github.

using windows 7 64bit.

any ideas? i cannot find anything on these forums on this and on google.....

'Incompatible' probably means that the file is not built for the same architecture you are compiling for.
I have seen this when mixing libs between 32-bit and 64-bit platforms, and I would not be surprised that the blackberry has a different architecture to both of these. If you downloaded the libBox2D.a file from somewhere or built it for a target other than blackberry, I guess you'll have to compile it with different settings to make sure it can link with the rest of your compiled files.

hmmm.... will try it out.

I am running windows 64-bit.

ok, not getting through.

the version of box2d i downloaded, which i imported into the qnx eclipse ide, is found at:

https://github.com/blackberry/Box2D

is there another build of box2d i should use?

I am not seeing anywhere in eclipse to build as 32bit or 64bit.

How can i do this?

thanks again.

Ok, i think i got it to build when choosing the device option only.

it's giving the error when you are building for the simulator. (makes no sense to me).

i don't have a device though, and the samples that come with the bb bnk compiled fine on the simulator.

so....to summarize....

-- box2d building for simulator or device.
-- testbed and helloworld not building for simulator, building for device...giving same error

i guess i will have to get a playbook.....dammit!!!! lol
