Hi, I am running the newest version of the Starterkit (SDK 1.10.0, URSim 5.8.0.10253) on a VirtualBox and I am having trouble getting the MyDeamon example cap to work. I want to run the python deamon, the rest is commented out, I have also commented out the compile section in the pom.xml file. Th…

Hi @anon91754699 I have seen issues with the execution permissions for the daemon in the felix-cache. That is resulting in the same symptoms that you are having. [Screenshot from 2021-01-12 03-02-07] In these cases there is no issue on the real robot. Best regards Ebbe

I have no problem and the daemon is runnable. Please check the below. [helloworld]

The permissions are set as in your screenshot and the Deamon starts without problems from the terminal. Is there any chance to obtain a log of the Deamon process?

I don’t know how to log the daemon process. The deamon may not be started once run as sudo. It is not recommemded to start as sudo. Please re-install ursim and try again. $ ./install-ursim.sh UR3 (or UR5, UR10)

No success unfortunately. I get a strange error now though 12:53:53.563 ERROR - Problem with installation of bundle {thread: Thread-3 , loggerClass: com.ur.polyscope.urcaps.internal.daemonservice.DaemonServiceManager} java.io.IOException: Could not set executable flag on file /home/ur/ursim/ursim-…

Could it be connected to the way I build the cap? In my pom.xml I put <ursim.home>~/ursim/ursim-5.8.0.10253</ursim.home> and I build with $ mvn install -P ursim Installing it manually after mvn install and putting it into the program folder failed as well though.

I have <ursim.home>/home/ur/ursim/ursim-5.8.0.10253</ursim.home> in pom.xml, can you try this?

I found the issue! It seems that the python setup got messed up somehow which lead to an import error. I have corrected the error and after reinstalling the ursim with ./install.sh it works now. I have also realized that logs of the deamon execution can be found under /ursim/ursim-<version>/serv…

Micheal could you elaborate on how you recognized a fault and what you did to fix it - I am having a similar issue.

Hi @anon36990825 , the fist thing I would suggest is to have a look into your Deamon log which you can find in /ursim/ursim-<version>/service/bundle@<yourcap>/log/log/current From this you should already get a good idea what is going wrong. Are you using a Python deamon? Do you require a certain …

Thanks for the response micheal. Unfortunately I don’t have a log appearing at that location. My service folder is appearing in my home directory for ur but is empty. I have notice that URSIM_ROOT doesn’t seem to be set - I think this may be why the service folder is in the wrong location Edit :…
