Where is ROS_ROOT?

[realtime-neil]

Do I detect some discrepancy in how ROS_ROOT is documented?

There's this:

// Next try to load the default config file from ROS_ROOT/config/rosconsole.config

-- https://github.com/ros/rosconsole/blob/6135fd34af6b3b48b2c779ec6626db7c2147048b/src/rosconsole/impl/rosconsole_log4cxx.cpp#L139

...which seems to agree with these:

$ cat /opt/ros/kinetic/share/ros/config/rosconsole.config
#
#   rosconsole will find this file by default at $ROS_ROOT/config/rosconsole.config
#
#   You can define your own by e.g. copying this file and setting
#   ROSCONSOLE_CONFIG_FILE (in your environment) to point to the new file
#
log4j.logger.ros=INFO
log4j.logger.ros.roscpp.superdebug=WARN
$ ( . /opt/ros/kinetic/setup.sh; echo "\${ROS_ROOT}=${ROS_ROOT}";)
${ROS_ROOT}=/opt/ros/kinetic/share/ros

But then, there's this:

ROS_ROOT sets the location where the ROS core packages are installed. export ROS_ROOT=/home/user/ros/ros export PATH=$ROS_ROOT/bin:$PATH

-- https://wiki.ros.org/ROS/EnvironmentVariables#ROS_ROOT

...which doesn't seem to exist in my installation:

$ ( . /opt/ros/kinetic/setup.sh; test -d "${ROS_ROOT}/bin"; echo $?; )

Is the documentation incorrect?

I am not sure if you have seen the ROS support guidelines but we kindly ask to raise questions like this on answers.ros.org instead.

The rational for asking all kind of questions in a single place is:

• There are many more people reading questions there so your chances on getting an answer and in a timely manner are much higher.
• In the future other users will search there for similar problems and can find your question and the potential answers.
• The issue tracker in this repo is used to track bugs, feature requests, etc. But your question is not such an action item.

Therefore I will close this ticket here for now. If you have asked your question on answers.ros.org please feel free to add a link to the question to this ticket so that future readers can find the related question.
