Can not build demo

[ByB]

As a newbie at Bullet, I 'm afraid I still need your help for my problem.

With VC++ I created a dialog based program (with MFC) and tried to integrate Bullet on it.

I included src directory in my project settings and added the following lines :
// Adding Bullet specific libraries
#pragma comment (lib, "C:\\BULLET\\bullet-2.75\\lib\\libbulletmath.lib")
#pragma comment (lib, "C:\\BULLET\\bullet-2.75\\lib\\libbulletdynamics.lib")
#pragma comment (lib, "C:\\BULLET\\bullet-2.75\\lib\\libbulletcollision.lib")
on my project.

At this point, compilation was working perfectly.

Then I used the code I found on this page : http://bulletphysics.org/mediawiki-1.5. ... ello_World
Now I get 3 errors when compiling, telling that "no overloaded function needs 3 parameters" at the following lines :

btAxisSweep3* broadphase = new btAxisSweep3(worldAabbMin,worldAabbMax,maxProxies);
btCollisionShape* fallShape = new btSphereShape(1);
btRigidBody* groundRigidBody = new btRigidBody(groundRigidBodyCI);
btRigidBody* fallRigidBody = new btRigidBody(fallRigidBodyCI);

I am quite sure the code is correct as I cut & paste it from the wiki. So I think I am missing something at project settings ... What can I do to make this demo work for me ? Is there something wrong with using the MFC and Bullet together ?

Thank you for your help.

FYI, the error code from VC++ compiler is always the same : "error C2661 : 'function' : no overloaded function takes number parameters"

FYI, I just noticed that only the Debug version of my program shows the problems I indicated before. The release version seems to compile with no problems.

May be that code (from wiki) you use was written for a diffrent version of Bullet than the one you have ... So realization of some methods may not coincide ...

I added step-by-step instructions for building the Hello World example with Visual Studio 2008 in the Bullet Wiki: http://bulletphysics.org/mediawiki-1.5. ... om_scratch

It is likely some global new/delete operator in the MFC or Windows headers that conflict with the new/delete operator in Bullet, see Bullet/src/LinearMath/btScalar.h

Code: Select all

#define BT_DECLARE_ALIGNED_ALLOCATOR() \
   SIMD_FORCE_INLINE void* operator new(size_t sizeInBytes)   { return btAlignedAlloc(sizeInBytes,16); }   \
   SIMD_FORCE_INLINE void  operator delete(void* ptr)         { btAlignedFree(ptr); }   \
   SIMD_FORCE_INLINE void* operator new(size_t, void* ptr)   { return ptr; }   \
   SIMD_FORCE_INLINE void  operator delete(void*, void*)      { }   \
   SIMD_FORCE_INLINE void* operator new[](size_t sizeInBytes)   { return btAlignedAlloc(sizeInBytes,16); }   \
   SIMD_FORCE_INLINE void  operator delete[](void* ptr)         { btAlignedFree(ptr); }   \
   SIMD_FORCE_INLINE void* operator new[](size_t, void* ptr)   { return ptr; }   \
   SIMD_FORCE_INLINE void  operator delete[](void*, void*)      { }   \

Can you try to include the Bullet include files before any MFC/Windows includes (or first in the stdafx.h / precompiled header file if you use those)?

Otherwise, we need more information about the errors. If above doesn't help, can you copy and past a few more lines of the actual error message (around 10 lines should do)?

Thanks,
Erwin

I have the same problem as ByB.

Here my entire error list:
Error 1 error C2661: 'btAxisSweep3Internal<BP_FP_INT_TYPE>::operator new' : no overloaded function takes 3 arguments
Error 2 error C2661: 'btSphereShape::operator new' : no overloaded function takes 3 arguments
Error 3 error C2661: 'btCollisionObject::operator new' : no overloaded function takes 3 arguments
Error 4 error C2661: 'btCollisionObject::operator new' : no overloaded function takes 3 arguments

When I try

Can you try to include the Bullet include files before any MFC/Windows includes (or first in the stdafx.h / precompiled header file if you use those)?

It say:
Error 1 fatal error C1189: #error : WINDOWS.H already included. MFC apps must not #include <windows.h> c:\program files\microsoft visual studio 9.0\vc\atlmfc\include\afxv_w32.h

There are a few possible solutions.

One is to undefine the global new and delete definitions, by adding those lines just before adding the Bullet headers:

Code: Select all

#undef new
#undef delete
#include "btBulletDynamicsCommon.h"

A better solution is saving the new/delete macros, then undefining them, and later restoring them. This is described here:
http://stackoverflow.com/questions/1128 ... riding-new
So before including the Bullet header(s), add:

Code: Select all

#ifdef new
#define NEW_WAS_DEFINED
#pragma push_macro("new")
#undef new
#endif

And afterwards add:

Code: Select all

#ifdef NEW_WAS_DEFINED
#undef NEW_WAS_DEFINED
#pragma pop_macro("new")
#endif

And the same for delete.

The last solution is to get rid of windows.h from the Bullet headers, there is only headerfile that needs a fix, which is Bullet\src\LinearMath\btQuickprof.h
Make sure to define

Code: Select all

#define BT_NO_PROFILE 1

Hope this helps,
Erwin

Thank you very much Erwin Coumans.
