hello world compile error

[Moustique]

Hello all,
I am new for Bullet, when I built Bullet "Hello world" application (create a ground plane and some spheres).

But I met link errors:

error LNK2001: unresolved external symbol "public: virtual void __thiscall btCollisionShape::getBoundingSphere(class btVector3 &,float &)const " (?getBoundingSphere@btCollisionShape@@UBEXAAVbtVector3@@AAM@Z)
1>First_Bullet.obj : error LNK2001: unresolved external symbol "public: virtual float __thiscall btCollisionShape::getAngularMotionDisc(void)const " (?getAngularMotionDisc@btCollisionShape@@UBEMXZ)
1>First_Bullet.obj : error LNK2001: unresolved external symbol "public: virtual float __thiscall btCollisionShape::getContactBreakingThreshold(float)const " (?getContactBreakingThreshold@btCollisionShape@@UBEMM@Z)
1>First_Bullet.obj : error LNK2001: unresolved external symbol "public: virtual void __thiscall btSphereShape::calculateLocalInertia(float,class btVector3 &)const " (?calculateLocalInertia@btSphereShape@@UBEXMAAVbtVector3@@@Z)
1>C:\Documents and Settings\zhwang\My Documents\My PhD\CODE in progress\code\Ogre Physics\OgreBullet\Bullet_Start\First_Bullet\Debug\First_Bullet.exe : fatal error LNK1120: 5 unresolved externals

I have linked BulletCollision.lib and BulletDynamics.lib and linearMath.lib,
the errors still exist!

I am dying and looking forward to your kind reply.

regards

How about header search paths to your header files? But I wouldn't have thought that would give those errors.

Hello,
thank you for your reply,
but the errors really happened. i think there is no problem of header files searching, if so there would have been some errors, like "can not open .h file".

I am thinking about the lack of lib files but I did not know which lib files are exactly needed, since I have added necessary lib files.

thank you for your help.

No, this is not a library not found error but a symbol not found error. Where did you get the library files from? If possible build them yourself or simply add the source files into your project. Ranlib them first into a library if required (windows 32k command limit bug).

Hello
Thank you for your reply,
and I followed ypur advice and just add the header files in my project, but unfortunately,
I failed again.

I could not figure out which files (header file or lib file) are missed.

Looking forward to your help!

I meant header files and source files (*.h and *.cpp) from bullet. The lib file is most probably lacking certain source files so add what you need. In general you need the source files except the BulletExtras ones.

Hello

I really do not understand.

Are you compiling with the bullet .cpp files or the .lib files? As mentioned, try without the lib files but compiling in the .cpp files from the Bullet distribution. This also includes LinearMath or how the directory is called. If you include the .cpp files in there the symbols should exist otherwise you have a seriously broken distribution.
