Real ros root

asked 2012-07-24 08:49:05 -0500

updated 2012-07-24 13:00:01 -0500

ROS_ROOT doesn't point to the root of a ros installation (i.e. where setup.sh, the base binaries, base libs reside), but I'm looking for installation root for use with a release script I'm writing.

Is there a way to figure this out programmatically? I know for example in fuerte I could simply figure out what the relative path is and adjust, but it's different for previous versions, and I'd like to use a sanctioned way to avoid edge cases/be future-proof.

Future releases of ROS will try to move away from the concept of a ROS_ROOT to be FHS compliant, meaning users will be able to install ROS like other other software into e.g. /usr/local/. So there will not be any ROS_ROOT anymore in the future. To be future-proof, do not assume that a ROS_ROOT exists, even in concept.

You can see these REPs for this:
