ignore cd path echo when using CDPATH, which breaks catkin usage

[rhaschke]

cd'ing echos the reached directory to the console when the CDPATH environment variable is used
This breaks the extraction of _CATKIN_SETUP_DIR, because now the directory is listed twice!

Can you please provide some more information for this?

Whenever I invoke cd with an absolute path it won't print anything since it does not use the CDPATH variable. Is that behavior different on your system?

Also if your CDPATH actually matches the cd folder used in the setup files do you actually have moved the workspace somewhere else and use CDPATH to keep it working?

Dear Dirk,

you are right, that cd with an absolute path won't print anything.
However, if you use a relative path, it will print the reached directory.
This proved to be a problem for building some packages (though, not all)
as well for sourcing the ROS environment, e.g. using source
install/setup.bash (without an absolute path).

For example, building groovy desktop from source, I get the following
error when building std_msgs:

catkin_generated/env_cached.sh: 12: .: Can't open
*/vol/ros/groovy/build_isolated/std_msgs/catkin_generated**
**/vol/ros/groovy/build_isolated/std_msgs/catkin_generated/setup_cached.sh*
make[1]: *** [CMakeFiles/std_msgs_generate_messages_cpp.dir/all] Error 2
make[1]: *** Waiting for unfinished jobs....

This error originates in the double output of the path in env.sh, which
is marked bold above.

I use CDPATH indepentendly from ROS. I didn't move the workspace. Plain
usage of CDPATH to ease hopping to certain (non-ROS) directories.

Kind regards, Robert
