c++ - undefined reference openscenegraph

Question

我正在尝试从这里编译一个 ROS OSG 项目 https://github.com/uji-ros-pkg/visualization_osg并不断收到以下错误:

    CMakeFiles/osg_interactive_markers_demo.dir/examples/osg_interactive_markers_demo.cpp.o: In function `main':
/home/user/catkin_ws/src/visualization_osg/osg_interactive_markers/examples/osg_interactive_markers_demo.cpp:28: undefined reference to `osgViewer::View::addEventHandler(osgGA::EventHandler*)'
/home/user/catkin_ws/src/visualization_osg/osg_interactive_markers/examples/osg_interactive_markers_demo.cpp:29: undefined reference to `osgViewer::View::addEventHandler(osgGA::EventHandler*)'
/home/user/catkin_ws/devel/lib/libosg_utils.so: undefined reference to `osg::NodeVisitor::NodeVisitor(osg::NodeVisitor const&, osg::CopyOp const&)'
/home/user/catkin_ws/devel/lib/libosg_interactive_markers.so: undefined reference to `osg::Group::removeChild(osg::Node*)'
/home/user/catkin_ws/devel/lib/libosg_utils.so: undefined reference to `osg::NodeVisitor::apply(osg::Geometry&)'
/home/user/catkin_ws/devel/lib/libosg_interactive_markers.so: undefined reference to `osg::Group::getNumChildren() const'
/home/user/catkin_ws/devel/lib/libosg_utils.so: undefined reference to `osg::NodeVisitor::apply(osg::Drawable&)'

据我了解应该存在链接问题，但我找不到修复它的方法。我的 CMake 文件如下所示:

cmake_minimum_required(VERSION 2.8.3)
project(osg_interactive_markers)

find_package(catkin REQUIRED COMPONENTS roscpp tf interactive_markers)

find_package(osg_utils REQUIRED)
find_package(osg_markers REQUIRED)
find_package(OpenSceneGraph REQUIRED COMPONENTS osgSim osgUtil osgDB osgFX osgGA osgTerrain osgViewer osgText osgWidget osgManipulator osg)

catkin_package(
INCLUDE_DIRS include
LIBRARIES ${PROJECT_NAME}

)

include_directories(include ${catkin_INCLUDE_DIRS} ${osg_utils_INCLUDE_DIRS} ${osg_markers_INCLUDE_DIRS} ${OpenSceneGraph_INCLUDE_DIRS})

  src/draggers.cpp
)

target_link_libraries(${PROJECT_NAME} ${catkin_LIBRARIES} ${OPENSCENEGRAPH_LIBRARIES}  ${OSGUTILS_LIBRARIES} ${OSGMARKERS_LIBRARIES} -lGLU )

add_executable(osg_interactive_markers_demo examples/osg_interactive_markers_demo.cpp)
target_link_libraries(osg_interactive_markers_demo ${PROJECT_NAME} ${catkin_LIBRARIES} ${OPENSCENEGRAPH_LIBRARIES} ${OSGUTILS_LIBRARIES} ${OSGMARKERS_LIBRARIES} -lGLU )

add_dependencies(${PROJECT_NAME} ${catkin_EXPORTED_TARGETS})

configure_file(osgInteractiveMarkersConfig.cmake.in ${CMAKE_CURRENT_BINARY_DIR}/lib/${CMAKE_PROJECT_NAME}Config.cmake @ONLY)

install(FILES ${CMAKE_CURRENT_BINARY_DIR}/lib/${CMAKE_PROJECT_NAME}Config.cmake 
        DESTINATION share/${CMAKE_PROJECT_NAME} )

install(
TARGETS
osg_interactive_markers_demo 
${PROJECT_NAME}
ARCHIVE DESTINATION ${CATKIN_PACKAGE_LIB_DESTINATION}
LIBRARY DESTINATION ${CATKIN_PACKAGE_LIB_DESTINATION}
RUNTIME DESTINATION ${CATKIN_PACKAGE_BIN_DESTINATION}
)
install(DIRECTORY include/${PROJECT_NAME}
DESTINATION ${CATKIN_PACKAGE_INCLUDE_DESTINATION})

有什么想法可以在这里完成吗？我是 OSG 的新手，非常感谢您的帮助。

问题已解决，原因是OSG安装错误(双重)
