Troubles compiling some code

[Kalash]

I have fuly compiled bullet using msvc and all seems to be find, I have libs, and examples working.

I tried to compile a small project but I have errors under codeblock:

CBulletObjectAnimator.cpp:: undefined reference to `btRigidBody::btRigidBody(float, btMotionState*, btCollisionShape*, btVector3 const&)'
CBulletObjectAnimator.cpp:: undefined reference to `btSphereShape::btSphereShape(float)'
obj\Release\include\Bullet\CBulletObjectAnimator.o(.rdata$_ZTV13btConvexShape[vtable for btConvexShape]+0x14):CBulletObjectAnimator.cpp:: undefined reference to `btCollisionShape::getBoundingSphere(btVector3&, float&) const'
obj\Release\include\Bullet\CBulletObjectAnimator.o(.rdata$_ZTV23btGImpactShapeInterface[vtable for btGImpactShapeInterface]+0x14):CBulletObjectAnimator.cpp:: undefined reference to `btCollisionShape::getBoundingSphere(btVector3&, float&) const'
CBulletPhysicsUtils.cpp:: undefined reference to `btConvexHullShape::btConvexHullShape(float const*, int, int)'
:: === Build finished: 5 errors, 0 warnings ===

I included the following libs:

libboxbox.lib
libbulletcollision.lib
libbulletdynamics.lib
libbulletmath.lib
libGIMPACT.lib
libGIMPACTUtils.lib
libconvexdecomposition.lib
libquicksteb.lib

What's wrong? Did I forgot something?
Thanks.

Ok, I searched help in the examples and I changed :

rigidBody = new btRigidBody((btScalar)mass,
motionState,
collisionShape,
localInertia
);

into :

Code: Select all

rigidBody = new btRigidBody(btRigidBody::btRigidBodyConstructionInfo(
    (btScalar)mass,
    motionState,
    collisionShape,
    localInertia)
  );

and one error disapeared.

The others still exists, the concerned code seems to be :

Code: Select all

btCollisionShape *collisionShape = new btSphereShape((btScalar)1.0f);

and

Code: Select all

btConvexHullShape* aConvexHullShape = new btConvexHullShape((btScalar*)&aBtVertBuffer[0], aBtVertBuffer.size());

(All the values mays be correct)

Hi, I have a similar problem. I also included all libraries from the lib folder and I get the following linker errors:

Code: Select all

CPhysicsSimulatorBullet.obj : error LNK2019: unresolved external symbol "public: void __thiscall btRigidBody::setDamping(double,double)" (?setDamping@btRigidBody@@QAEXNN@Z) referenced in function "public: virtual class IPhysicsObject * __thiscall CPhysicsSimulatorBullet::createTriggerObject(int,class IEntity *,struct SShape &)" (?createTriggerObject@CPhysicsSimulatorBullet@@UAEPAVIPhysicsObject@@HPAVIEntity@@AAUSShape@@@Z)
CShapeConverterBullet.obj : error LNK2001: unresolved external symbol "public: virtual void __thiscall btBoxShape::calculateLocalInertia(double,class btVector3 &)const " (?calculateLocalInertia@btBoxShape@@UBEXNAAVbtVector3@@@Z)

.\..\bin/main.exe : fatal error LNK1120: 4 unresolved externals

I changed the constructor of btRigidBody accordingly to the previous post and that solved one problem, but this 4 unresolved externals still remain.

I cannot imagine what could be wrong with for example setDamping(double,double), I looked into the examples, but it seems that nothing has changed. I'm kinda stuck with this atm....

Any help appreciated, thanks,
Ronin

Edit: The errors occured with switching from Bullet 2.62 to 2.66 btw...

I am using btRigidBody constructor like that

Code: Select all

rigidBody = new btRigidBody(mass,
    motionState,
    collisionShape,
    localInertia)
  );

but I got a fatal error "cannot open input file 'libboxbox.lib' ", I don't understand where is the problem

@blt_nub : Check your link to libboxbox.lib.

Did you already figure out about the issue with codeblock? It is not clear what is going wrong.

Can you try to:
- clean and rebuild all libraries
- use CMake to generate Codeblock projectfiles, and use codeblock to build the libraries and application (instead of using msvc)

Hope this helps,
Erwin

I used CMake to create Makefile for MinGW but I can't compile, I've some errors:

Code: Select all
