I'm following the source installation on Debian Stretch on an armel platform. When I come to the final step of running catkin_make_isolated, I get the following error:

$ ./src/catkin/bin/catkin_make_isolated --install -DCMAKE_BUILD_TYPE=Release
Traceback (most recent call last):
  File "./src/catkin/bin/catkin_make_isolated", line 12, in <module>
    from catkin.builder import build_workspace_isolated
  File "./src/catkin/bin/../python/catkin/builder.py", line 66, in <module>
    from catkin_pkg.terminal_color import ansi, disable_ANSI_colors, fmt, sanitize
ImportError: No module named terminal_color

It seems this is due to a version mismatch, but I'm not sure where exactly. I'm running this in a Docker file, so it should be very reproducible:

Looking at http://wiki.ros.org/Client%20Libraries it appears as if a lot of languages have ROS client libraries. However, upon closer inspection, half of the ones I looked at have not been updated in years and provide only the bare minimum features.

Are there any bindings outside Python and C++ that are mature enough to be used in anything more than a toy project?

Which programming language have mature and maintained client libraries? Looking at http://wiki.ros.org/Client%20Librarie

I have a Catkin package that generates several binaries and libraries, but unlike some other packages, pkg-config can't find them.

ROS seems to have set the path to both my Kinetic installation, as well as my workspace.

echo $PKG_CONFIG_PATH 
somelocation/workspace/devel/lib/pkgconfig:somelocation/ros_catkin_ws/install_isolated/lib/pkgconfig

When I ask pkg-config --list-all about it, it does know about all of the ROS libraries, and also about things I installed in my own workspace, like joy and uuid. But it does not find the libraries I wrote myself.

I went over to the CMakeLists.txt of joy to see if I could find anything obvious that has to be done to generate the correct files, but can't see anything. There is no .pc file in the repo either. I also tried to google around, but all results are about using external packages inside ROS, not about using ROS package outside it.

Currently I'm just doing this, but that apparently does not get you any pkg-config files. Full source: https://github.com/RoboTeamTwente/rob...

  add_library(Skill
        $<TARGET_OBJECTS:treegen>
        $<TARGET_OBJECTS:tactics>
        $<TARGET_OBJECTS:utils>
        $<TARGET_OBJECTS:skills>
        $<TARGET_OBJECTS:conditions>
        )
  add_dependencies(Skill 
        ${${PROJECT_NAME}_EXPORTED_TARGETS}
        ${catkin_EXPORTED_TARGETS}
        )

When I run this, there is no output

$ pkg-config --list-all | grep -i skill

So what is the correct way to tell pkg-config about my library, just like joy and uuid?

Ok. Thanks!

Ah! Catkin makes a pkg-config entry for the whole roboteam_tactics, rather than any individual libraries I define. If I

I need to use ROS with a library that does not support Python 2, which is over a decade old at this point. I'm finding mixed information about Python 3 support in ROS Melodic.

I'm installing from source using the instructions on the wiki. I used Python 3 to install the initial packages

sudo pip3 install -U rosdep rosinstall_generator wstool rosinstall

After setting up my locale correctly, I got up to the point where wstool has initialised the standalone workspace. But after that I run rosdep to install all the dependencies, and I see a lot of Python 2 packages scrolling by.

rosdep install --os=debian:stretch --from-paths src --ignore-src --rosdistro melodic --skip-keys=sbcl -y

Is there a way ROS Melodic can run on Python 3?

It might be worth mentioning that I could not care less about what the whole system runs on, as long as I can have a single Python 3 node to receive some messages and use this particular Python library. So if I can install rospy on Python 3 that should be enough I think?
