[SOLVED]Building bullet extras

hello every one, I am new to Ogre world and I am trying to build OgreBullet on Ubuntu 11.04, I can´t download deb package, it gives me some strange errors, but everything was good when i tried to build it from source, i just use autogen.sh configure make and make install, but when trying to build it i get error that ConvexBuilder.h cannot be found, so i searched and i found out that it is part of Bullet Extras,so i just copied it to the folder,but it seems i need to build bullet extras and thats what i just cannot find out how to do that. I build Bullet, but it didn´t build extras. So can anybody give me any advice on how to build extras, or any other way to get OgreBullet working? Thanks a lot and sorry for my English.

You would probably be better of building bullet with the CMake files, omniyo wrote a guide here:

viewtopic.php?f=12&t=14193


cmake . -G "Unix Makefiles" -DBUILD_DEMOS=FALSE -DINSTALL_EXTRA_LIBS=TRUE
make -j4
sudo make install


Your problem with the tutorial (from the main forum), you can resolve by updating the OgreBullet_Collision_test.h header:


OgreBullet_Collision_testFrameListener(
SceneManager *sceneMgr,
RenderWindow* win,
Camera* cam,
Vector3 gravityVector,
AxisAlignedBox bounds)


First of all thank you very mutch for your second advice. To the first thing, i followed the guide exactly, but I´am still getting errors when trying to build Ogre Bullet tutorial, /usr/local/lib/libOgreBulletCol.so: undefined reference to `btPolyhedralConvexShape::initializePolyhedralFeatures()'
/usr/local/lib/libOgreBulletDyn.so: undefined reference to `btAngularLimit::set(float, float, float, float, float)'
collect2: ld returned 1 exit status so I want to ask whether it matter if i have my libConvexDecomposition and libGIMPACTUtils like static library(.a)? And second whether i need to specify the path to bullet/ogre libs/includes somewhere? Please note I´am not only the Ogre and Bullet n00b but linux n00b too:D I don´t know anything about makefiles at all.

I haven't tried running against the static bullet libs, however you can build bullet shared libs by adding -DBUILD_SHARED_LIBS=TRUE to your bullet build command line (see bullet INSTALL).

What happens when you try to build the demo from the command line, something like:


g++ -o test OgreBullet_Collision_test.cpp -I. \
`pkg-config --cflags --libs OGRE OIS` `pkg-config --cflags OgreBullet bullet` \
/media/sda8/Libraries/Physics/bullet_static/lib/libOgreBulletDyn.a \
/media/sda8/Libraries/Physics/bullet_static/lib/libOgreBulletCol.a \
/media/sda8/Libraries/Physics/bullet_static/lib/libBulletDynamics.a \
/media/sda8/Libraries/Physics/bullet_static/lib/libBulletCollision.a \
/media/sda8/Libraries/Physics/bullet_static/lib/libLinearMath.a \
/media/sda8/Libraries/Physics/bullet_static/lib/libConvexDecomposition.a \
/media/sda8/Libraries/Physics/bullet_static/lib/libGIMPACTUtils.a


OR


g++ -o test OgreBullet_Collision_test.cpp -I.\
`pkg-config --cflags --libs OGRE OIS` `pkg-config --cflags OgreBullet bullet` \
-L/media/sda8/Libraries/Physics/bullet_static/lib \
-Wl,-static -lOgreBulletDyn -lOgreBulletCol -lBulletDynamics -lBulletCollision -lLinearMath -lConvexDecomposition -lGIMPACTUtils -Wl,-Bdynamic


Does it matter if it cannot find OpenCL when running cmake command? PS: building from command line wasn´t successful due to including, and i really don´t want to rewrite all my includes into the bash
Edit: I´ve tried to build it with -DINSTALL_BUILD_SHARED_LIBS=TRUE, but no luck, still no shared libs for extras

Finally solved, it was caused by bad library types of Bullet, you must link static Bullet libs but shared OgreBullet libs, thats the only configuration that works for me:D
Here is my Linker input to be perfectly clear:
/usr/lib/libOgreMain.so /usr/lib/libOIS.so /usr/local/lib/libOgreBulletCol.so /usr/local/lib/libOgreBulletDyn.so /usr/local/lib/libBulletCollision.a /usr/local/lib/libBulletDynamics.a /usr/local/lib/libLinearMath.a /usr/local/lib/libConvexDecomposition.a /usr/local/lib/libGIMPACTUtils.a
