[solved] bullet compilation issue

[madMAx4]

Hi,
when i try to compile bullet with g++-3.4.6 or g++-4.1.1 i get the following errors:

Code: Select all

In file included from /mnt/kk/devel/bullet-2.50b/src/BulletCollision/CollisionDispatch/btCollisionDispatcher.h:25,
                 from /mnt/kk/devel/bullet-2.50b/src/BulletCollision/CollisionDispatch/btCollisionWorld.h:73,

make: *** [all] Error 1

same with new 2.50b

i used to comment these lines out:

Code: Select all

btAlignedObjectArray.h line 58:

m_data[i].~T();

and

Code: Select all

btAlignedObjectArray.h line 125:

m_data[m_size].~T();

i think gcc doesn't compete with the syntax.

so is there any other way to do that?

[Erwin Coumans]

Which platform are you compiling on? What STL version is installed?

Can you report the compiler/STL versions implementation of vector::destroy for your platform?

Also, can you try to replace
m_data.~T();
by
m_data.T::~T();

Does that help?
Thanks,
Erwin

thx for your reply,

i'm compiling under gentoo linux with libstdc++ v3.3.4
compiler is as said above gcc-i686-pc-linux-gnu-3.4.6.

i forgot to say that this error only occurs when i include "btBulletDynamicsCommon.h" into my project.
compilation of the library works without any error.

That is an important detail, so it seems to be a conflict with your source code/other includes.

Can you put the #include "btBulletDynamicsCommon.h" at the very first line of your .cpp source file, and see if that helps? Try to avoid including it in another header file.

Thanks,
Erwin

yeah it's working now, thx. i put

Code: Select all

#include "btBulletDynamicsCommon.h"
#include "btBulletCollisionCommon.h"

at the top of my .cpp as you said.

at first, these includes were above them:

Code: Select all

//irrlicht
#include "irrlicht.h"

//common
#include <iostream>
#include "glm.c"
#include <wchar.h>
