Question

我正在关注有关如何创建ROS自定义消息的“ WS Newman's”教程。编译“消息/服务'example_msg / Num'的依赖性已更改。请重新运行cmake”

时，发生以下错误

Num.msg有

std::advance

Cmakelists.txt

Header header
int32 demo_int
float64 demo_double

package.xml

project(example_msg)

find_package(catkin REQUIRED COMPONENTS
  roscpp
  std_msgs
  message_generation
)
add_message_files(
   FILES
   Num.msg
#   Message2.msg
)
generate_messages(
 DEPENDENCIES
 std_msgs
 )
catkin_package(

CATKIN_DEPENDS message_runtime
)
include_directories(
  include ${catkin_INCLUDE_DIRS}
# include
  ${catkin_INCLUDE_DIRS}
)
add_executable(example_ros_message_publisher
  src/example_ros_message_publisher.cpp
)
add_dependencies(example_ros_message_publisher ${${PROJECT_NAME}_EXPORTED_TARGETS} ${catkin_EXPORTED_TARGETS})
target_link_libraries(example_ros_message_publisher
  ${catkin_LIBRARIES}
)

example_ros_message_publisher.cpp

  <exec_depend>roscpp</exec_depend>
  <exec_depend>std_msgs</exec_depend>
  <export>
     </export>
</package>

当我运行catkin_make install时，出现以下错误。 “消息/服务'example_msg / Num'的依赖关系已更改。请重新运行cmake。”

柳絮中的错误。要触发更深层次的重建，可以触摸包含CMakeLists.txt的软件包的example_msg/Num文件。
