Great Work Oscar.
For making ROSplan work for noetic.
Is something missing because the build is breaking?

The problem is: cc1plus: error: -Werror=deprecated-copy: no option -Wdeprecated-copy
I introduced a workaround which works on my PC, however it does not seem to work on the integration server, you can try on your PC, maybe you are lucky

[harshkakashaniya]

You are right !!!
There are some warnings while it is been build.
But it is working fine on my PC.
Thank you ...

Dear oscar,
I had a question for you.
can we add negative conditions in our problem file ?

Planner is not able to plan if I have a negative condition in problem file.
for example:
(not (docked kenney))

does not work ..

any solutions.

Hi It never makes sense to put negative facts in a problem file - PDDL uses the closed world assumption and, therefore, absence of a fact is the way you say the fact is false. Some planners, but not all, handle negative preconditions in the actions. POPF/OPTIC do not. There are solutions to this - the standard one is to "mirror" conditions. That is, when you want the condition (not (P)) as a precondition, you create the condition (notP) and add that as precondition. You now ensure that every action that adds P deletes notP and every action that deletes P adds notP. Another option is to try to find a planner that works with negative preconditions. Cheers Derek

Dear Derek,
Thank you very much for your detailed answer and export preaching.
now I understood the thinking behind this.
Everything makes much more sense now.

Regards,
Harsh

I am having issues with the sensing interface:

Hi @harshkakashaniya,
I just opened a PR #277 to address the issue with the sensing interface. This will fix the issue you're experiencing, and it's due to Noetic using Python 3.

Great Work Oscar.

Is something missing because the build is breaking?

The problem is: cc1plus: error: -Werror=deprecated-copy: no option -Wdeprecated-copy I introduced a workaround which works on my PC, however it does not seem to work on the integration server, you can try on your PC, maybe you are lucky

Hi @oscar-lima ,

Thanks for the noetic extension. I also faced problems building ROSPlan for noetic. I fixed it by adding -Wno-error in [1] in the rosplan_dependencies CMakeList.

[1] SET (RDDL_CMAKE_CXX_FLAGS "${RDDL_CMAKE_CXX_FLAGS} -g -Wall -W -Wno-sign-compare -Wno-deprecated -ansi -pedantic -Werror -std=c++11 -O3 -DNDEBUG -fomit-frame-pointer -Wno-error=deprecated-copy")

Tks for this !!
