[ros-users] Problem with Rosmake on Timer

Hi to all,

I trying to reproduce the Timer Package from http://www.ros.org/wiki/roscpp_tutorials/Tutorials/Timers and these are the commands i entered.


1. roscreate -pkg --xcproj Timer roscpp std_msgs
2. rospack export --lan=cpp --attrib=cflags Timer
3. rospack export --lan=cpp --attrib=flags Timer
4. rosmake --rosdep --install

But this following errors occurs
----------------------------------------------------------------------------------------------------------------------------------------------------
Usage: rosmake [options] [PACKAGE]...

rosmake: error: ambiguous option: --rosdep (--rosdep-install, --rosdep-yes?)
Traceback (most recent call last):
  File "/opt/ros/cturtle/ros/bin/rosmake", line 65, in <module>
    if rma.main():
  File "/opt/ros/cturtle/ros/tools/rosmake/src/rosmake/rosmake.py", line 706, in main
    options, args = parser.parse_args()
  File "/usr/lib/python2.6/optparse.py", line 1396, in parse_args
    self.error(str(err))
  File "/usr/lib/python2.6/optparse.py", line 1578, in error
    self.exit(2, "%s: error: %s\n" % (self.get_prog_name(), msg))
  File "/usr/lib/python2.6/optparse.py", line 1568, in exit
    sys.exit(status)
SystemExit: 2
---------------------------------------------------------------------------------------------------------------------------------------------------
What does this error means?

if i change the command to rosmake only,

  -- Configuring incomplete, errors occurred!
--------------------------------------------------------------------------------------------------------------------------------------------------------------------}
