Small Patch

Added to OgreAddons tracker.

MinGW refuses to link to the inline getRay...() functions. It appears that MinGW is compiling the functions out of existence. The inline variety works fine with MSVC.

Making the addEntity and addMesh methods virtual so that they can be redefined by an inheriting class. Useful for application specific specialization.

Applied, Thanks a lot !
Does Linux/mingw build out of the box from SVN now ?

I think you may still be missing the bug in OgreBulletCollisionsTerrainShape.h where "OgreBulletCollisionsPrerequisites.h" should be "OgreBulletCollisionsPreRequisites.h".

../Collisions/include/Shapes/OgreBulletCollisionsTerrainShape.h:5:47: error: OgreBulletCollisionsPrerequisites.h: No such file or directory


Also some of the material files need updated for ogre 1.6.x:

01:58:56: Can't assign material 19 - Default to SubEntity of chassis50 because this Material does not exist. Have you forgotten to define it in a .material script?

eg, chassis.material:

-material 19 - Default
+material "19 - Default"



On Linux (bullet2.7.4beta1) I also had a problem with ConvexDecomposition. When building bullet it appears the ConvexDecomposition headers/libs dont appear to be installed. When building the demo I get the following error:


/media/sda1/LIBRARIES/OGRE/ogreaddons/ogrebullet/Collisions/src/.libs/libOgreBulletCol.so: undefined reference to `ConvexBuilder::~ConvexBuilder()'
/media/sda1/LIBRARIES/OGRE/ogreaddons/ogrebullet/Collisions/src/.libs/libOgreBulletCol.so: undefined reference to `ConvexBuilder::process(ConvexDecomposition::DecompDesc const&)'
/media/sda1/LIBRARIES/OGRE/ogreaddons/ogrebullet/Collisions/src/.libs/libOgreBulletCol.so: undefined reference to `ConvexBuilder::ConvexBuilder(ConvexDecomposition::ConvexDecompInterface*)'
collect2: ld returned 1 exit status
make: *** [OgreBullet_Demo] Error 1


To resolve the above I linked libConvexDecomposition.a against OgreBulletCol and CPPFLAGS to point to the ConvexDecomposition headers.

Thx. Material and Case typo fixed now.

How can I add that to linux build ? any hindsight/patch ?

hey dermont, when trying to build the Demos I'm having exact the Problem you mentiond.
I've tried to solve it by adding -lConvexDecomposition when building ogreBullet, but it ain't worked. Seems I've missed something, could you please describe in detail how you solved it.

thanks

I think if you're building bullet via autotools config it's called libconvexdecomposition and is in bullet-2.74/Extras. The lib name may be different if your using scons. To build OgreBullet something like this (where rpath may not be needed):


CXXFLAGS="-I/media/sda1/LIBRARIES/OGRE/ogre-v1-6-2/Samples/Common/include -I/media/sda1/LIBRARIES/PHYSICS/bullet-2.74/Extras/ConvexDecomposition" LDFLAGS="-L/media/sda1/LIBRARIES/PHYSICS/bullet-2.74/Extras -Wl,-rpath,/media/sda1/LIBRARIES/PHYSICS/bullet-2.74/Extras" LIBS="-lconvexdecomposition" ./configure


Thanks for your reply.
I've found the libconvexdecomposition in the Extras folder of bullet and have build and installed it.
The lib name I've used seems to be valid, cause it is accepted, but my initial Problem is still not solved by that.

I still get the undefined reference to `ConvexBuilder::~ConvexBuilder()' and so on.

How are you building the demo? Are you linking against libconvexdecomposition? The only other thing I can think of trying is to add the convexdecomposition lib to the end of your ogrebullet/Collisions/src/Makefile.am, e.g:

libOgreBulletCol_la_LIBADD = \
$(OGRE_LIBS) \
$(bullet_LIBS) \
-lconvexdecomposition


Yay thx that solved that Problem. now I can Build the Demos.

But when I tried to run them I got this:
An exception has occured: OGRE EXCEPTION(5:ItemIdentityException): Unable to locate vertex program called Ogre/BasicVertexPrograms/AmbientOneTexture. in GpuProgramUsage::setProgramName at OgreGpuProgramUsage.cpp (line 61)

I think you need to add some Ogre resources, I got fed up trying to figure which and added everything. This is my resource.cfg file.

I've had tryed it that way but it aint worked, but with your resource file it works
