[人工智能]ROS写srv且自动建立h头文件

新建包

mkdir -p ROSworkspace/second_ws/src
cd ROSworkspace/second_ws
catkin_make

新的srv的pkg

cd src
catkin_create_pkg service_demo roscpp rospy std_msgs
cd service_demo
mkdir srv
cd srv
gedit Greeting.srv

里面输入代码

int64 a
int64 b
---
int64 sum

然后要修改CMakeList.txt和package.xml

Package.xml里面新增

<build_depend>message_generation</build_depend>
<exec_depend>message_runtime</exec_depend>

CMakeList.txt修改

find_package(catkin REQUIRED COMPONENTS
  roscppge
  rospy
  std_msgs
  message_generation
)

add_service_files(
  FILES
  Greeting.srv
)

generate_messages(
#   DEPENDENCIES
#   std_msgs
)

catkin_package(
#  INCLUDE_DIRS include
#  LIBRARIES service_demo
#  CATKIN_DEPENDS roscpp rospy std_msgs
#  DEPENDS system_lib
  LIBRARIES service_demo
  CATKIN_DEPENDS message_runtime
)
)

最后一行加上
include_directories(include ${catkin_INCLUDE_DIRS})

最后一步

回到second_ws的目录下

catkin_make

在devel中的include中可以看到.h文件
