How to add the tape_measure branch to my existing gazebo 7.9 installation? Please answer in detail.

edit

That branch hasn't been touched in a long time, so I suspect the amount of effort to revive it would be non-trivial.

I haven't tried it, but the steps should go something like this:

1. Clone gazebo

   hg clone http://bitbucket.org/osrf/gazebo
   cd gazebo
   

2. Move to latest gazebo7 branch

   hg up gazebo7
   

3. Merge in tape_measure. This is the tricky part, because you'll need to solve many conflicts

   hg merge tape_measure
   

4. Then follow the usual installation process

   mkdir build
   cd build
   cmake ..
   make -j8
   sudo make install
   

You'll probably need to tweak the code a few times until it builds successfully. Also note that the tape_measure branch has never been completed, so it may not work as expected. That said, if you get it to work, it would be great if you could contribute it back to the community!

Cheers
