There are several tutorials on MoveIt website on C++ API like [this one](http://docs.ros.org/kinetic/api/moveit_tutorials/html/doc/pr2_tutorials/planning/src/doc/move_group_interface_tutorial.html). I've downloaded them, built using `catkin build` and now can run those examples using `roslaunch`. But how exactly do I compile and run my own code? If I copy one of the example cpp-files to `${CATKIN_WS}/moveit_mycode/`, say `move_group_interface_tutorial.cpp`, edit a couple of lines, then what do I do next?
My take is that I shouldn't use `gcc` straightforwardly, but rather `catkin build`, which means I need a `CMakelists.txt` or something similar. Also, should I write a `.launch` file? I realize this is a very basic question, but I couldn't figure it out. I couldn't find any info on the topic, too, neither on MoveIt website nor anywhere else. I'd appreciate any help!
I'm on ROS Kinetic, Ubuntu 16.04.

Can I build nodes in packages separately?
Can I build nodes in packages separately and use own CMakeLists for them?
One of my nodes can't use C++ 11, but other depends on it. Also I want to separate them to git-submodules.

Can we directly install ROS Kinetic packages on PC running Ubuntu 16.04 without installing ROS Kinetic on that PC ?
Hi,
I'm new to the ROS and Ubuntu world.While I was trying to install ROS Kinetic on PC running Ubuntu 16.04 a new question arose to my mind that "**whether it is always necessary to install first the ROS Kinetic on the PC running Ubuntu 16.04 or we can directly install ROS Kinetic packages like TurtleSim,Catkin,etc. on the PC using the command 'sudo apt-get install ros-kinetic-[PACKAGE_NAME]' without installing the ROS on PC(which will include some of the packages already in it)."**
And if it is possible to directly install packages on the PC running Ubuntu without completely installing ROS on PC,will we be able to used all the commands of the ROS like roscore,rosrun,rospack,source the environment,catkin,etc. in that PC.
Link:- http://wiki.ros.org/kinetic/Installation/Ubuntu
Any help in these question will be highly appreciated.

move_base: does not publish/subscribe anything when roslaunch from local catkin workspace
Hello all. I'm having trouble getting my own local nodes (in a catkin workspace called arc_ws) to run with the navigation stack.
I have a slightly modified launch file from navigation_stage/launch. It looks as follows:

But while doing a catkin_make, I still get the error fatal error: dynamicEDTOctomap.h: No such file or directory

ROSserial trys to build all packages in catkin workspace
I have a simple catkin workspace with two packages:
gababot_core
jake
The gababot_core depends on ROSserial. The jake package does not. If I 'purge' my workspace and remove `build/` and `devel/` and then try to rebuild `catkin_make` it crashes with the following error:
*** Warning, failed to generate libraries for the following packages: ***
jake ('NoneType' object has no attribute '_md5sum')
Traceback (most recent call last):
File "/opt/ros/kinetic/share/rosserial_arduino/make_libraries.py", line 91, in
rosserial_generate(rospack, path+"/ros_lib", ROS_TO_EMBEDDED_TYPES)
File "/opt/ros/kinetic/lib/python2.7/dist-packages/rosserial_client/make_library.py", line 561, in rosserial_generate
raise Exception("Failed to generate libraries for: " + str(failed))
Exception: Failed to generate libraries for: ["jake ('NoneType' object has no attribute '_md5sum')"]

make[1]: *** [gababot_core/CMakeFiles/gababot_core_ros_lib.dir/all] Error 2
Makefile:138: recipe for target 'all' failed
make: *** [all] Error 2
So ROSserial tries to generate arduino libraries for jake. It doesn't make sense, because jake doesn't depend on ROSserial (esp. not rosserial_arduino). When I run `catkin_make` a second time it actually works fine and builds everything as I expect.
So why does ROSserial try to build libraries for all packages in my catkin folder instead of just the ones dependent on it? And how do I turn it off? :D

What is the benefit of metapackages?
I can't figure out what is the benefit of using metapackages, as opposed to just putting stuff in different folders.
It seems metapackages can't be whitelisted or blacklisted, they cannot be used while defining dependencies of other catkin packages. They are not allowed to have common scripts for e.g. software delivery. It's just a package.xml and CMakeLists.txt.
So what's the point?

How to subscribe to ros_arduino_msgs?
I'm using the ROSArduinoBridge to connect an ODROID to an Arduino and I'd like to subscribe to a digital sensor topic that the ROSArduinoBridge is publishing. I can't figure out the C++ syntax to be able to do this. Has anyone ever done this before and would be able to help me figure this out? I've checked the basic ROS Subscriber tutorials and tried to #include "ros_arduino_msgs/Digital.h", but the compiler says it can't find that file and I don't know what it should be. Any help would be appreciated, thanks!

ROSberryPi - Install new packages
Hi all! I am not totally new to ROS,but it is the first time I use it on a Raspberry Pi.
I have a question regarding the installation of new packages on Rosberry Pi. Do I have to launch this command everytime I install a new package?
sudo ./src/catkin/bin/catkin_make_isolated --install -DCMAKE_BUILD_TYPE=Release --install-space /opt/ros/indigo
Can't I just use catkin_make --pkg and compile just that new package? Cause this catkin_make_isolated takes a lot of time.
Moreover do I have to use that one also when I create a pkg by myself or can I just use catkin_make?
Thx!!

Linking issues with catkin: undefined references

Catkin: Building install space from prebuilt devel space
Hello,
I have a catkin/ros project with full install rules, and I use 'catkin build' to build the project. I am trying to make it so I can build the project in a normal devel/build space, and then generate an installer from those results, but I am having issues understanding how catkin wants me to do this.
Building with an install space enabled produces a correct installer. Unfortunately, enabling the install space requires rebuilding everything.
catkin clean #Start Fresh
catkin build #Build devel space
catkin config --install #Enable install space
catkin build #Fails saying it is necessary to clean first
catkin clean
catkin config --install #Already set above, just making it clear this is set.
catkin build #Correctly builds install space! But cleaning and rebuilding (with different compiler flags is not acceptable).
My current solution is
catkin clean #Start Fresh
catkin build #Build devel space
catkin build -j1 --make-args install #Necessary to make catkin/cmake not randomly crash
The j1 is there because without it, catkin has threading issues and fails randomly (likely because I am triggering the install rules without catkin knowing so it does not create the install locks). I am trying to figure out the RIGHT way to make an install from an already build project, but the documentation has not mentioned it, or is referring to very old versions of catkin that are no longer applicable.
Are there any documents or commands/arguments I should look into?

installing my ros package
I have a python node that takes xbox 360 controller inputs and publishes to cmd_vel topic. This node works fine when the ROS master is running on my laptop.
The robot i've built has a raspberry pi on it which runs the ROS master, and I use my laptop to run RVIZ and the node mentioned above, communicating with the ROS master via wifi. The problem is that i cant run the node on my laptop with the ros master being on the pi.
The comms between the two computers works fine, installed nodes on either work fine. I.e RVIS runs happily on the laptop and i can rostopic echo stuff. But when i try and run the node that i made in the catkin_ws i get something along the lines of the following -
Unable to register with master node [http://192.168.0.101:11311/]: master may not be running yet. Will keep trying.
Every time i reboot my machine i need to source the bash file in devel or whichever one it is (ROS reminds me of a messy university dorm room sometimes), I think this is the problem, as if i try and run a preinstalled node like the teleop key, it can't talk to the ros master. But then if i source ~/.bashrc (which is done by default in every new terminal) it can't find my package, which has my joystick node in it.
My question is, how do i install this package onto my system, much in the same way apt-get does when you install a ros package that way? A google search makes me think rosinstall might be what im after, but trying to find meaningful documentation is like trying to boil water in a chocolate tea pot. As per with anything ROS related.
Cheers in advance.

reset CATKIN_WHITELIST_PACKAGES
I am building a subset of the packages in my catkin workspace using CATKIN_WHITELIST_PACKAGES. However, when I want to rebuild the whole workspace (without CATKIN_WHITELIST_PACKAGES set), it still only builds the whitelisted packages. I assumed that the whitelist is only temporary for each build, but it seems like it is globally stored. I couldn't find any documentation on it.
If I want to change the whitelist, the only thing I can do is to remove `build` and `devel`. Can anyone provide me with some more information about CATKIN_WHITELIST_PACKAGES, i.e. what exactly it does and where it is stored?

How to edit/compile ROS source code
Good afternoon,
I am trying to encrypt ros logs for a project, I currently have jade installed and running on an ubuntu OS. I believe the files I need to edit are in the ros_comm packages (rosconsole and rosout cpp files) that I found on the ROS Core Stack Github page.My biggest hurdle right now that I am facing is that I am having difficulty setting up my environment that would let me compile the source code. If you know of any tutorials or information that would give me an idea of how to edit and compile sections of the source code it would be greatly appreciated.
Thank you for your time,
Tyler

ROS message subfolder
Hi,
I noticed that ROS does not correctly see message files in subfolders of the "msg" folder. The add_message_files command can take a DIRECTORY command which works partly:
add_message_files(
DIRECTORY
msg/subfolder1
FILES
testmessage.msg
)
Both `catkin_make_isolated` and `catkin build` run perfectly but after a `source devel/setup.bash`, the `rosmsg list` command does not show this testmessage. If I change the subfolder name to something different in the CMakeLists file, cmake complaints about the missing path. Hence, the folder path is recognized partly.
The only solution I found was to move all message files out of subfolders such they are directly placed at e.g., `msg/testmessage.msg`. Then, the `rosmsg list` command shows the message.
Is there another way to use subfolders for message definitions?
Thanks!

JetBrains CLion IDE setup for ROS
I've downloaded it a couple of days ago, but I still have not figure out how to configure it correctly to work with ROS.
If I import a simple ROS project it gives me the following error, but I can compile (and run) it from the terminal:
Error: By not providing "Findcatkin.cmake" in CMAKE_MODULE_PATH this project has asked CMake to find a package configuration file provided by "catkin", but CMake did not find one.
Could not find a package configuration file provided by "catkin" with any of the following names:
catkinConfig.cmake catkin-config.cmake
Add the installation prefix of "catkin" to CMAKE_PREFIX_PATH or set "catkin_DIR" to a directory containing one of the above files. If "catkin" provides a separate development package or SDK, be sure it has been installed.
I'd like to know where to properly set these environmental variables and how can I get the equivalent of `catkin_make` from inside the IDE.
Thanks in advance!

Why run catkin_init_workspace inside src folder?
I don't unstand why we run catkin_init_workspace inside the src folder, shoudn't it be the root folder, which is the catkin workspace folder?
$ mkdir -p ~/catkin_ws/src
$ cd ~/catkin_ws/src
$ catkin_init_workspace
