The name of the file "AddTowInts.srv" is wrong in the CMakeLists.It should be "AddTwoInts.srv", so it appeared "Message service file not found" when building. It is a very stupid mistake!

You need to add the line message_runtime to catkin_package e.g.

catkin_package(
    CATKIN_DEPENDS
    message_runtime
)

BTW, you should also add to the package.xml file the following line

 <run_depend>message_runtime</run_depend>

Thank you for your help. I did as what you said, but it doesn't work.I couldn't find where errors are now! When I used catkin_make install in my catkin workspace, it outputed these:

make: *** [cmake_check_build_system] Error 1
Invoking "make cmake_check_build_system" failed

I don't have enough points to upload files, so I share them in my google email.

Hmm... Everything looks in order. Try running catkin make install a few times. Sometimes it helps
