Rock-display crashes when displaying Point Clouds or envire maps in Ubuntu 16.04

Ubutnu 16.04: Rock-display crashes when displaying point clouds or envire maps with the following output:

Unknown frame: world
Qt has caught an exception thrown from an event handler. Throwing
exceptions from an event handler is not supported in Qt. You must
reimplement QApplication::notify() and catch all exceptions there.

terminate called after throwing an instance of 'std::runtime_error'

Unknown frame: world

Rather looks like a bug in the visualization plugin that expects a "world" frame to be present.

[planthaber]

or the newer click handler in vizkit3d has this issue @arneboe

[arneboe]

I'll add it to my todo list :D
Is this a blocker or can you work around the bug for the time being?

[mmaurus]

@arneboe It is hard to check if the created maps from slam3d are correct, if I can't see them.
I have other things to do, but I would need it in 2 weeks.

[arneboe]

@mmaurus I'll try :-)

[arneboe]

@mmaurus I am having a hard time reproducing this bug. The tests in slam/maps/test/viz all work for me. Can you provide a minimal example that fails?

[mmaurus]

@arneboe Try the navigation example as described here:
https://git.hb.dfki.de/transfit/documentation

Before, check if the checkout of slam3d with tag 1.0.0 worked

So far I spent 4 hours trying to compile. Following bugs so far.

• kccdtools is missing osdeps: libcoin80-dev libsoqt-dev-common liblpsolve55-dev libsoqt4-dev
• libply forces g++5 but osdep not set
• rock_Python crashes with python3
• ndlcom/RobotConfig is missing osdep libxml++-2.6
• sensor_processing/kccdtools is missing ossdeps: libsoqt4-dev liblpsolve55-dev libsoqt-dev-common
• imu_xsens is missind osdep libudev
• control/joint_control is missing osdep libgsl
• sempr-core is missind osdeps: libodb-dev odb libodb-sqlite-dev libgeos-dev libgeos++-dev libgeographic-dev, sqlite
• ndlcom/ RobotConfig benötigt is missing gem nokogiri, libffi-dev
  *planning/motion_planners/src/planners/trajopt/trajopt_sco/include/sco/SQPConfig.h needs to include math.h

@planthaber @mmaurus

Still I have more that 10 build errors left before I can start experimenting with your setup...

[mmaurus]

That's weird because I've never heard of most of these osdeps.
And I did a new install last week, which worked fine.

Which OS are you using?

[arneboe]

Freshly installed ubuntu 18.04.
Probably you had most of them installed already :)

[mmaurus]

Ah ok... check this out:
https://github.com/sempr-tk/sempr/wiki/SEMPR-on-Ubuntu-18.04
There are some special steps for sempr on Ubuntu 18.04

[mmaurus]

I also tried the tests in slam/maps/test/viz. They all work for me, too...
So the error might be somewhere else.

[arneboe]

rock_transfit/planning/orogen/motion_planning_libraries/motion_planning_libraries.orogen:20: invalid type motion_planning_libraries/Config: cannot find /motion_planning_libraries/Config in registry (OroGen::ConfigError)

This is where I am stuck right now. Do I need the motion_planning_libraries for the example?

[arneboe]

I give up. I spent ~6 hours trying to get transfit to run and still cannot even run the first of the four ruby scripts. I will gladly look into it again if you can provide a working example (e.g. a docker image) that crashes vizkit but I cannot spend more time on fixing unrelated transfit bugs.
