1、具體問題

CMake Error at /opt/ros/kinetic/share/genmsg/cmake/genmsg-extras.cmake:155 (message):

2、背景

在跟古月老師的ROS視訊課中出現的一個問題

在做話題訂閱釋出之後建立了功能包内的消息類型，如下所示：

3、建立服務，添加服務相關配置

但是出現如下錯誤：

CMake Error at /opt/ros/kinetic/share/genmsg/cmake/genmsg-extras.cmake:155 (message):
  generate_messages() must be called after add_service_files()
Call Stack (most recent call first):
  linlinshi/CMakeLists.txt:66 (add_service_files)

4、問題分析

添加服務配置應該在添加消息之上，意為先配置服務後配置消息

Generate_messages(DEPENDENCIES std_msgs)

## Generate services in the 'srv' folder
# add_service_files(
#   FILES
#   Service1.srv
#   Service2.srv
# )

add_service_files(FILES AddTwoInts.srv)

           

5、變更為

## Generate services in the 'srv' folder
# add_service_files(
#   FILES
#   Service1.srv
#   Service2.srv
# )

add_service_files(FILES AddTwoInts.srv)

Generate_messages(DEPENDENCIES std_msgs)
           

6、再次編譯，即可成功
