Hi, I have a problem with catkin_make that stop me from building my project. He seems to compile my c++ file before generating my message and service.

####
#### Running command: "make -j1 -l1" in "/home/philippe/design3/app/build"
####
Scanning dependencies of target Kinocto
[  7%] Building CXX object kinocto/CMakeFiles/Kinocto.dir/src/Kinocto.cpp.o
In file included from /home/philippe/design3/app/src/kinocto/src/Kinocto.cpp:1:0:
**/home/philippe/design3/app/src/kinocto/include/Kinocto.h:10:34: fatal error: kinocto/StartKinocto.h: No such file or directory**
compilation terminated.
make[2]: *** [kinocto/CMakeFiles/Kinocto.dir/src/Kinocto.cpp.o] Error 1
make[1]: *** [kinocto/CMakeFiles/Kinocto.dir/all] Error 2

In bold, wecan see that he can't find my service StartKinocto.h that doesnt exist because it havent been generated first... If I comment the code that use this service the service file is generated after Kinocto.cpp :

#### Running command: "make -j1 -l1" in "/home/philippe/design3/app/build"

Is that normal? What should I do?

OK, so I found out what was the problem... Even if your .srv is in your package you still need to add your package to his own dependencies... Kind of weird.

In my CMakeList.txt of the package kinocto I had:

add_executable(Kinocto src/Kinocto.cpp)

After the line above, I simply added this :

add_dependencies(Kinocto kinocto_gencpp)

No more error and the .srv files are generated.

I think it should be documented in the tutorials...

It is documented in this tutorial: http://www.ros.org/wiki/ROS/Tutorials/WritingPublisherSubscriber%28c%2B%2B%29 (catkin). if you see another tutotiral that misses that, tell us of fix it.

@KruseT It should be documented in the CreatingMsgAndSrv Tutorial. This issue has proven to be a headache.

Also, if using catkin make sure this is part of your code

## Generate added messages and services with any dependencies listed here
## std_msgs is neccessary to generate message and service files
generate_messages(
   DEPENDENCIES
   std_msgs
)

catkin_package(
   LIBRARIES ptu46
   CATKIN_DEPENDS message_runtime
)
