I am trying to install the indigo release "robot" set of packages on armhf from source.

For the class_loader package, the changelog states:

0.2.0 (2013-03-13)

• use find_package for Poco/dl instead to make it work on other platforms
• update Poco cmake file to include libdl on non-windows systems
• No longer CATKIN_DEPEND on console_bridge

However the packages CMakeLists.txt still contains (on line 9)

find package(console_bridge REQUIRED)

Am I safe in removing the requirement?

Thanks in advance

I am writing node to publish several sonar readings in a skirt being driven by an arduino. My node listens on the serial port and advertises an array of sensor_msgs/Range. I am depending on the ros-hydro-serial package to drive the serial port. I wanted to handle communications between the arduino and the node with parameter values. Therefore I am trying to look for and set all possibilities using ROS parameters. (Note: issuetracker does not seem to have anything on the serial package so I thought I would post here first. I have taken out support for stopbits_one_point_five and am not being held up. No urgency but would like to know if I am doing something wrong)

I was using the attributes of a serial connection in a switch and received a compiler error. "error: duplicate case value".

<snip of code>
switch (foo) {
   . . . 
   case serial::stopbits_one_point_five :
      this;
      that;
      break;
   case serial::stopbits_two :   //compiler issues the duplicate case value error for this line
      the other;
      break;
    . . . 
}
</snip>

I note in looking at the header it contains.

<snip of the ROS hydro serial.h header>
/*!
 * Enumeration defines the possible stopbit types for the serial port.
 */
typedef enum {
  stopbits_one = 1,
  stopbits_one_point_five,
  stopbits_two = 2
} stopbits_t;
</snip>

This has the affect of assigning the same value for the stopbits_one_point_five and the stopbits_two values.

My environment: Ubuntu 12.04 gcc 4.6.3

Thank you very much - that did the trick. I had to add visualization to the SUBSYS_DEPS in .../examples/CMakeLists.txt file and start over.

I am attempting to build ros from source. while attempting to link pcl_example_extract_clusters_normals I get the error:

/usr/bin/ld cannot find -lpcl_visualization

It looks like visualization has not yet been built and am guessing there is a build order issue.

Alternatively, is there a safe way to make and install a sub-component?

I am getting several errors in downloading tf2 and geometry-experimental packages with wstool (ubuntu:precise).

No. New to ROS and am not sure what packages I will need. This is a group of us and my task is to get the full to build on pi.

Any pointers as to what is wrong would be greatly appreciated...

Obtained package using wstool for desktop-full. OS is debian:wheezy (raspberry pi)
