ROS Indigo on Ubuntu 14.04 LTS

ROS Lunar on Ubuntu 16.04 LTS

catkin_make starts up and gets as far as BUILD_SHARED_LIBS is on and then hangs. There are no high cpu processes listed in top, and no output to dmesg at all.

What else can I check to investigate why it hangs?


A clean install of Lunar worked fine until today.

Delete build and devel, and try running things as follows:

catkin_make VERBOSE=1

If things hang, see what it was doing.

Seeing the in that ps output: how many packages do you have, and what sort of machine is this?

Verbose output: Still hangs after BUILD_SHARE_LIBS is on.

We have one package with 8 nodes. This machine is an Intel NUC, we previously used a Surface Pro 3 that worked flawlessly for the past year or more, then recently stopped working.

Does catkin_tools work? That is not a solution, but just trying to get some more info.

catkin_tools: command not found

Is it a command I should be running? Do I need to have something else installed first? I did the ros-lunar-desktop-full install.

catkin build just ran for an hour and didn't get anywhere...

Let's take a step back: can you build an empty workspace (with catkin_make or catkin build, I don't care). So:

  1. open a new terminal (no auto sourcing anything)
  2. source /opt/ros/$distro/setup.bash
  3. mkdir -p /tmp/empty_ws/src
  4. cd /tmp/empty_ws
  5. catkin_make

I followed your instructions exactly and it behaves the same as before. Hangs after BUILD_SHARED_LIBS is on :(

Thank you for your help, I really appreciate it! We are definitely at our wit's end with this thing and none of the similar issues we found online had a working solution.

There was a single package in our system that did not adhere to the naming conventions (package name contains capital letters). Catkin threw a warning and then hung on build until the package was removed/renamed.

It wasn't obvious that it was a fatal error considering the message was prefixed with "Warning" and not "Error".

Thanks for reporting back.

Not adhering to naming conventions should definitely not be a fatal error or cause Catkin to hang.

If you can create an MWE and report it here that would be great.
