Hi again,

I'm trying to add Bullet Extension made by penguins916 here, however I'm getting Linker errors (unresolved externals) when building Horde3D.dll. I tried with Bullet 2.8.2 and 2.74 libraries that can be found on the GameEngine version. I also tried to compile a separate Bullet download package (2.8.2) on GitHub but with same errors.

Here is the error list thrown by VC2008

Code:

Added this to CMakeList.txt on the root folder

Code:
option(HORDE3D_BUILD_BULLET "Build the Bullet extension into Horde3D" ON)
if(HORDE3D_BUILD_BULLET)
   add_subdirectory(Extensions/Bullet)
   #include path to bullet
   #include_directories(/usr/include/bullet/)
   
   set(HORDE3D_EXTENSION_SOURCES
      ${HORDE3D_EXTENSION_SOURCES}
      ${Horde3D_SOURCE_DIR}/Extensions/Bullet/Source/egPhysics.h
      ${Horde3D_SOURCE_DIR}/Extensions/Bullet/Source/egPhysics.cpp
      ${Horde3D_SOURCE_DIR}/Extensions/Bullet/Source/extension.h
      ${Horde3D_SOURCE_DIR}/Extensions/Bullet/Source/extension.cpp
      ${Horde3D_SOURCE_DIR}/Extensions/Bullet/Source/utMath.h
      ${Horde3D_SOURCE_DIR}/Extensions/Bullet/Source/utXMLParser.h
      ${Horde3D_SOURCE_DIR}/Extensions/Bullet/Source/utXMLParser.cpp
      )
   set(HORDE3D_EXTENSION_INSTALLS
      ${HORDE3D_EXTENSION_INSTALLS}
      "extMan().installExtension( new Horde3DBullet::ExtBullet() );\n"
      )
   set(HORDE3D_EXTENSION_INCLUDES
      ${HORDE3D_EXTENSION_INCLUDES}
      "\n#include \"Extensions/Bullet/Source/extension.h\"\n"
      )
   set(HORDE3D_EXTENSION_LIBS
      BulletCollision BulletDynamics LinearMath
      )
      
endif(HORDE3D_BUILD_BULLET)


and pointing to include and lib directories of bullet once I generated the solution.

Any ideas?

EDIT For some reason CMake did not include the Terrain and Sound generated libs in the Additional Library Dependencies. Works ok now. :)
