Question

I am trying to launch this file with a bumblebee

<launch>
  <node pkg="camera1394stereo" type="camera1394stereo_node" name="camera1394stereo_node" output="screen" >
    <param name="video_mode" value="format7_mode3" />
    <param name="format7_color_coding" value="raw16" />
    <param name="bayer_pattern" value="grbg" />
    <param name="bayer_method" value="" />
    <param name="stereo_method" value="Interlaced" />
    <param name="camera_info_url_left" value="" />
    <param name="camera_info_url_right" value="" />
  </node>
</launch>

as it is explained in http://wiki.ros.org/camera1394stereo but I keep getting this error

ERROR: cannot launch node of type [camera1394stereo/camera1394stereo_node]: can't locate node [camera1394stereo_node] in package [camera1394stereo]

However when I do sudo apt-get install ros-indigo-camera1394stereo y do not get any error and everything is installed without problems.

Does anybody know why cannot I launch the file?

It looks like the latest Indigo binary release, 1.0.3, lacked the necessary CMake commands to install the node and nodelet. That has apparently been fixed in source, but not yet re-released. It appears that a 1.0.5 release may be in the works. There was an issue #4 regarding this, now closed. I suggest contacting the maintainer by commenting on that issue, maybe re-opening it.

For now, you'll have to check out the source into your catkin workspace and build it yourself.

How to build from source:

First, create a catkin workspace:

$ source /opt/ros/indigo/setup.bash
$ mkdir -p ~/catkin_ws/src
$ cd ~/catkin_ws/src
$ git clone https://github.com/srv/camera1394stereo.git

Install all the dependencies:

$ cd ..
$ rosdep install --from-paths src --ignore-src --rosdistro indigo -y

Then, build everything:

$ catkin_make
$ source devel/setup.bash
