2019-05-20 02:34:26 -0500 marked best answer Documentation of stack not updating after being added to rosdistro/kinect.yaml

The problem: I followed the guidelines in Indexing Your ROS Repository for Documentation Generation and everything seemed to worked fine until the documentation page generation.

The stack: auction_mehtods_stack

The steps undertaken:

1) updated https://github.com/ros/rosdistro/blob... with the new stack for indexing.

2) The pull request was accepted.

3) The indexer job finished and status reported ok.

4) However, the documentation page for the corresponding stack in wiki.ros.org did not correctly update to include the new distro documentation.

The question: Did someone faced a similar problem, or have any suggestion on how to resolve this issue?

Hello, @adrianohrl I noticed that something changed on the repository I stored the code. Tomorrow I'm planning to put it to github and update the documentation for the stack. Sorry for this inconvenience, and thanks for the heads-up!

2013-07-08 13:36:04 -0500 answered a question Problem at json_prolog

I was geeting a similar error while issuing the command $rosrun json_prolog json_prolog ias_semantic_map

The result was: find: `/jre/lib/': No such file or directory Cannot find libjsig ... maybe you need to set JAVA_HOME?

Since I'm using the openjdk (default in Ubuntu 10.04) I did the following to get it to work.

1) type java -version to see that it is installed


2) check if have the following path /usr/lib/jvm/default-java/jre/lib


3) if the path exists then $sudo nano /etc/bash.bashrc


4) add at the end of the file

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

export JAVA_HOME

PATH=$PATH:$JAVA_HOME/bin

export PATH


5) save and exit


6) restart the terminal or open a new one and test the command (in my case $rosrun json_prolog json_prolog ias_semantic_map)
