Does not configure on Ubuntu 18.04

[mmaurus]

Hi.
This rock task does not configure on Ubuntu 18.04 with the following errors / Typelib Warnings:

• invalid type motion_planning_libraries/Config: cannot find /motion_planning_libraries/Config in registry (OroGen::ConfigError)
• ignoring /std/pair</double,/double>, it has private base classes
• ignoring /motionplanninglibraries/Config since its field mFootprintRadiusMinMax is of the ignored type /std/pair</double,/double>

Looks like the typelib can't figure out std::pair.

Any solutions?

Can you verify that this is solved by rock-planning/planning-motion_planning_libraries#16 ?

[mmaurus]

Yes I can confirm that. Now, it fails when linking with undefined reference to 'RTT::internal::DataSource::getType() const' and undefined reference to 'RTT::internal::DataSource::getTypeName() const'

I just had the same issue and it was "solved" for me by removing the Task "Test" from the orogen-file. What does this test? Does someone know if it is required?

@mmaurus Did you find another solution?

Update: Ok, it solved it on my notebook, but on Sherpa I have the same problem again, now with the Task "Task".

@2maz Is this also the reason that this is not in rock-master19.06?

[mmaurus]

I still have this problem with rock debian package 20.01. Not with 19.06!

@mmaurus as we figured out wIth master-20.01 this linking issue exists, when using return type bool for an operation. I am afraid, however, this will only be fixed in the upcoming release, which will have a clean way of linking and using includes based on separate package prefixes - anticipating EO June for bionic/amd64 ready for testing.

[mmaurus]

@2maz unfortunately, this issue is not fixed with the new debian packages 20.06

[mmaurus]

One solution/workaround would be to change the operation "generateEscapeTrajectory" to returning an int instead of a bool
