I found the problem. Some files of knowrob_basics_tutorial, such as init.pl in the prolog folder and ccrl2_map_objects.owl in the owl folder have '.in' at the end of their name. I removed that and everything seems to work now. So rename init.pl.in to init.pl and it works.

I was trying one of the first CRAM tutorial and it says 'launch lisp REPL.' I have installed roslisp but when i run 'rosrun roslisp_repl repl' as the roslisp tutorial says to do, I get "[rosrun] Couldn't find executable named repl below /opt/ros/groovy/share/roslisp_repl"

Any ideas what I am doing wrong?

Btw, I am using Ros Groovy on ubuntu 12.04.

Thanks!

It is a rosbuild stack using this tutorial: http://wiki.ros.org/catkin/Tutorials/... and I have run rosmake knowrob and it showed me no errors.

Ok yes. I did miss that. I have now installed knowrob and the tutorials from source like the link showed. And both knowrob and knowrob_basics_tutorial are in /home/groovy_workspace/stacks and are found by roscd. But still I get the same error.

In the git tutorial they assume you have installed ros from svn. But I have not and I don't know what the correct directories are in my case. I have a catkin workspace in my home folder. Should I install it there?

What I did was install knowrob like it said in the tutorial and this works fine. For the knowrob tutorials I used http://wiki.ros.org/ROS/Tutorials/Sta... to install it from github in the opt/ros/groovy/stacks, where knowrob also is.

I installed ros groovy on ubuntu 12.04. The version of swipl is SWI-Prolog version 5.10.4 for i386. When I roscd knowrob I get /opt/ros/groovy/stacks/knowrob

Is this solved? I put the knowrob_basics_tutorial package in /opt/ros/groovy/stacks/ and I still get this error.

Hi

In the MainActivity of android_tutorial_teleop there are some things wrong I think:

In MainActivity.java these are used:

• R.id.virtual_joystick_snap
• R.id.virtual_joystick
• R.id.visualization

And in res/menu/settings_menu.xml

• @+id/virtual_joystick_properties
• @+id/virtual_joystick_snap

And in res/layout/main.xml

• @+id/virtual_joystick

The compiler looks for these ids in the R.java of android_honeycomb_mr2 but the only (relevant) id that is in there is public static int virtual_joystick_layout=0x7f05003b;.

How can I solve this. I could really use this tutorial.

Cheers!

Hi

I wanted to run rosjava_tutorial_pubsub and rosjava_tutorial_services in eclipse. These need the project rosjava. But there is an error in the source code. In the src/test/java, int the org.ros package in ParameterServerTestNode.java At line number 112 it gives this error: The method setInt32Array(List<integer>) in the type TestArrays is not applicable for the arguments (int[])

Just to let you know.

I have troubles installing rosjava_core.

• hg clone https://code.google.com/p/rosjava rosjava_core (this ran fine)
• ./gradlew gives me this error:

Building > :rosjava_actionlib:compileJava > Resolving dependencies ':rosjava_a:rosjava_actionlib:compileJava

FAILURE: Build failed with an exception.

• What went wrong: Could not resolve all dependencies for configuration ':rosjava_actionlib:compile'. > Could not find group:ros, module:message.actionlib_msgs, version:0.0.0-SNAPSHOT. Required by: ros.rosjava_core:rosjava_actionlib:0.0.0-SNAPSHOT

Then I tried this tutorial: http://docs.rosjava.googlecode.com/hg/rosjava_core/html/installing.html

• sudo apt-get install python-setuptools (ran fine)
• easy_install --prefix ~/.local -U rosinstall

error: can't create or remove files in install directory

The following error occurred while trying to add or remove files in the installation directory:

[Errno 2] No such file or directory: '/home/katrijne/.local/lib/python2.7/site-packages/test-easy-install-4763.write-test'

The installation directory you specified (via --install-dir, --prefix, or the distutils default setting) was:

/home/katrijne/.local/lib/python2.7/site-packages

This directory does not currently exist. Please create it and try again, or choose a different installation directory (using the -d or --install-dir option).

• export PATH=$PATH:~/.local/bin
• ... (see the tutorial)
• easy_install --prefix ~/.local -U pygments (gives the same error as the previous easy_install)
• roscd rosjava_core
• ./gradlew install

Can you help me?

export ROS_WORKSPACE=what_you_need_it_to_be. But if you made your workspace with rosws you don't need to change it manually.

ROS_WORKSPACE is the path to the folder where you put all the packages you make yourself. Sometimes also for extra packages you want to install. You should check out the tutorials on ros.org.

Try to look for the files in ./build/install/rosjava_tutorial_pubsub/bin
