Hello, When I try to install ros by following the wiki, I get this error :

$ rosinstall ~/ros "http://packages.ros.org/cgi-bin/gen_rosinstall.py?rosdistro=cturtle&variant=base&overlay=no"

/Library/Python/2.5/site-packages/rosinstall-0.5.16-py2.5.egg/rosinstall/vcs/svn.py:49: Warning: 'with' will become a reserved keyword in Python 2.6
Traceback (most recent call last):
  File "/usr/local/bin/rosinstall", line 5, in <module>

    with open(os.devnull, 'w') as fnull:
            ^
SyntaxError: invalid syntax

I have python 2.5:

$ ls -l `which python`
lrwxr-xr-x  1 root  wheel  72 11 sep  2010 /usr/bin/python -> ../../System/Library/Frameworks/Python.framework/Versions/2.5/bin/python

I found the same problem happend on debian - link

How can I solve the problem?

To get this to work on python 2.5 you need to add

from __future__ import with_statement

at the top of the rosinstall script.

Two questions:

  1. Why OS 10.5? It's ancient!
  2. Why cturtle? Diamondback is better. (See the Diamondback OS X install instructions)

Installing diamondback on OS X is, itself, a tricky process, but it does work. See this howto for extensive documentation on getting everything working.
