ROS学习（二）-自定义话题消息

如何自定义话题消息

1. 定义msg文件；
2. 在package.xml中添加功能包依赖；

message_generation
message_runtime

3. 在CMakeList.txt添加编译选项；

find_package(......  message_generation)

add_message_files(FILES Person.msg)
generate_messages(DEPENDENCIES std_msgs)

catkin_package(......  message_runtime)

4. 编译生成语言相关文件；

在文件路径src路径下添加完publisher 和 subscriber cpp文件后
在CMakeList.txt中配置编译规则

add_executable(person_publisher src/person_publisher.cpp)
target_link_libraries(person_publisher ${catkin_LIBRARIES})
add_dependencies(person_publisher ${PROJECT_NAME}_generate_messages_cpp)

add_executable(person_subscriber src/person_subscriber.cpp)
target_link_libraries(person_subscriber ${catkin_LIBRARIES})
add_dependencies(person_subscriber ${PROJECT_NAME}_generate_messages_cpp)
