Problem with the semantic_map editor knowrob_gui running

As the semantic map editor is moved into knowrob_gui. But the tutorial and document has not been updated. Do anyone know what is the problem with this:

When I compiled the knowrob_gui successfully in groovy on Ubuntu 12.04 and run it

$rosrun knowrob_gui KnowRobGUI

It displays that:

find: ‘/jre/lib/’: No such file or directory Cannot find libjsig ... maybe you need to set JAVA_HOME?

It is not clear in the tutorial in knowrob org

PS: @moritz would you please update the tutorial if possible?

Well, the error message is rather clear, you need to set the JAVA_HOME environment variable. Google helps how to do this:

export JAVA_HOME=/usr/lib/jvm/default-java

You can either enter this command in the shell or add it to your ~/.bashrc to have it set automatically in every newly opened shell.

Thanks, I set the JAVA_HOME at first but not work. I re-installed a new system and it is OK, but new error occurred. It says [FATAL ERROR Could not find system resources

Try setting the SWI_HOME_DIR environment variable as indicated here: http://www.swi-prolog.org/FAQ/FindResources.html

export SWI_HOME_DIR=/usr/lib/swi-prolog
