[SOLVED] `DaemonContribution::start()` always ends in `ERROR`

URCap Development URCaps SDK
5

Thank you very much @hch!

As you pointed out runit was not installed at all, probably because when I installed the simulator, the script crashed without advertise the failure.

I don’t know exactly what was wrong the first time but I’m going to describe here all the modifications that I have done to properly install the simulator and the SDK on Ubuntu 16.04.

Thank you again and hope this helps,
Alessandro Tondo @qbrobotics

Install URsim PolyScope 3.3.3.292 on Ubuntu 16.04

  1. open the install.sh in the ursim-3.3.3 directory;

  2. openjdk-6-jre is no more supported on Ubuntu 16.04; switch to openjdk-8-jre by renaming the proper field of commonDependencies (I cannot say that this has no drawbacks, it seems to work well though):

     commonDependencies='libcurl3 openjdk-8-jre ...'

  3. change the java version control accordingly (note the 1.8.0 instead of the 1.6.0):

     versionString=`java -version 2>&1 | head -n1 | grep 1\.8\.0`
 if [[ -z $versionString ]]
 then
         echo "Please select Java version 1.8 using update-alternatives"
         return
 fi

  4. [optional] if you have installed a non-english Ubuntu, probably your desktop directory is not called ~/Desktop. In such a case use something like this when creating the executable shortcuts or simply rename the path with your desktop directory name:

     # source the user directories for every language (then use $XDG_DESKTOP_DIR)
 source ~/.config/user-dirs.dirs
 # create launch files
 echo "Create shortcuts on the desktop"
 for TYPE in UR3 UR5 UR10
 do
 	FILE=$XDG_DESKTOP_DIR/ursim-$VERSION.$TYPE.desktop
 	...

  5. you are almost done, just open a terminal and type ./install.sh;

  6. [optional] if you have previously installed the URCaps SDK, you might force the dependencies installation with something like apt-get install -f;

  7. [optional] if you get stuck like me while installing runit, please follow this topic. In brief, you have to comment out the final part of /var/lib/dpkg/info/runit.postinst because it tries to call upstart which is no longer used in the newer Ubuntu releases, and than simply force the installation process (i.e. sudo apt-get install -f);

  8. [optional] if you get stuck on point 7, simply rerun ./install.sh again;

  9. if everything goes as expected you will find three executable shortcuts on your desktop.

Install URCaps SDK 1.0.0.23 on Ubuntu 16.04

  1. open the install.sh in the sdk-1.0.0-23 directory;

  2. [optional] if you have previously installed the simulator, you might force the debian installation at the end of the installer (i.e. use --force-all):

     sudo dpkg -i --force-all urtool/*.deb

  3. [important] check if the debian package has been installed correctly through dpkg -s urtool3. It should prompt something like this (be sure that the status is Status: install ok installed):

     Package: urtool3
 Status: install ok installed
