1 建立package
catkin_create_pkg beginner_tutorials roscpp
2 导入Qt
Qt中打开整个工作空间的src/CMakeLists.txt 在倒数第二行最后加入，最后一行include是为了写代码时候智能提示
FILE(GLOB children ${CMAKE_SOURCE_DIR}/*)
FOREACH(child ${children})
IF(IS_DIRECTORY ${child})
file(GLOB_RECURSE dir_files "${child}/*")
LIST(APPEND extra_files ${dir_files})
ENDIF()
ENDFOREACH()
add_custom_target(dummy_${PROJECT_NAME} SOURCES ${extra_files})
include_directories(/home/xiaophuang/catkin_ws/devel/include)
右键点击project，执行run cmake,输入的参数是-DCMAKE_BUILD_TYPE=Debug
这样workspace下面的所有非空文件夹都会被导入
3 添加文件，文件夹
在package下新建一个srv文件夹（在Qt下面好像不能建文件夹，在外面建立文件夹）
在Qt下新建一个AddTwoInts.srv文件放在srv文件夹下面，输入
int64 a
int64 b
----
int64 sum
修改package.xml，CMakeLists.txt
测试一下
rossrv show beginner_tutorials/AddTwoInts
4， Debug
要是按F5提示(注意不要选错要调试的程序)
This does not seem to be a "Debug" build.
