and this repository

https://github.com/mikejmills/vision_...

works. It seems it is a matter of using the latest openCV 3.1.0, 3.1.0 does not work with the standard cv_bridge.

Used mikejmills version and compiled correctly.

I'm trying to install cv_bridge on a BeagleBone running Debian. I am using ROS Indigo.

I am getting the following error:

[  5%] Building CXX object vision_opencv/cv_bridge/src/CMakeFiles/cv_bridge_boost.dir/module_opencv2.cpp.o

Tried the usual Google searching and couldn't find an answer. I have OpenCV installed (3.1.0), and verified that OpenCV is working.

Anyone have any thoughts/suggestions?

Thanks Mark

Thanks dornhege, that's what I was hoping. I'll give it a try today. I normally have a separate workspace for custom packages, but I am trying to keep the released ROS packages and my packages separate.

@gvdhoorn - a combination of both. There are some packages that recompile/link every time (camera_calibration_parsers is an example), while others just check to see if anything changed. All the messages are rebuilt everytime. And yes it takes that long. I'm compiling on the BeagleBone, from a SDcard, so I have to look into the speed there.

I am developing on a BeagleBone Black, running Debian Wheezy, using ROS Indigo. All the packages I need to use need to be compiled, which is no big deal.

But, right now when I need to compile a single package, all the packages are re-built. Currently I'm up to about 78 packages that I am building every time I add a new one, and that takes about 2 hours.

The steps I am using to build are (these are steps listed here http://wiki.ros.org/indigo/Installati... section 3) :

rosinstall_generator ros_comm ros_control joystick_drivers --rosdistro indigo --deps --wet-only --exclude roslisp --tar > indigo-custom_ros.rosinstall

(add my new package to the list above step)

wstool merge -t src indigo-custom_ros.rosinstall
wstool update -t src

rosdep install --from-paths src --ignore-src --rosdistro indigo -y -r --os=debian:wheezy

sudo ./src/catkin/bin/catkin_make_isolated --install -DCMAKE_BUILD_TYPE=Release --install-space /opt/ros/indigo

in the last step, can I add the --pkg <name> command somewhere in there so I can only compile that one package? Like this?

sudo ./src/catkin/bin/catkin_make_isolated ***--pkg name***  --install -DCMAKE_BUILD_TYPE=Release --install-space /opt/ros/indigo

Is there another way? Is anything going to break if I do this?

Thanks!

I appreciate everyones feedback. I should have re-read the original link on installing on Debian. I did do a rosdep check... but missed the part about urdfdom(I reran it to verify)... Since this is Debian Wheezy on a BeagleBone, I need to compile a lot of system files including urdfdom, along with all ROS packages... Sometimes my eyes get crossed :)

By following the compile instructions for liburdfdom, I was able to successfully compile the rs_control package.

Thanks!

I have had ROS (indigo) running on a BeagleBone Black (running debian), by compiling everything, following this link:

http://wiki.ros.org/indigo/Installati...

I then tried to compile in ros_control (following all the steps at the bottom of the page)

rosinstall_generator ros_comm ros_control --rosdistro indigo --deps --wet-only --exclude roslisp --tar > indigo-custom_ros.rosinstall

The compile failed when trying to compile joint_limit_interface:

  By not providing "Findurdfdom.cmake" in CMAKE_MODULE_PATH this project has

  CMake did not find one.

  Could not find a package configuration file provided by "urdfdom" with any
  of the following names:

    urdfdomConfig.cmake
    urdfdom-config.cmake

  Add the installation prefix of "urdfdom" to CMAKE_PREFIX_PATH or set
  "urdfdom_DIR" to a directory containing one of the above files.  If
  "urdfdom" provides a separate development package or SDK, be sure it has
  been installed.

Looking around, there seems to be some talk on this, but I am still confused on how to proceed with the build.

Anyone have any step by step instructions on how to proceed?

Thanks!

This is my first attempt at ROS, and I have spent a lot of time researching and reading, but there is one "small" piece that escapes me... Here is my setup

PC (Ubuntu 14.04) Full ROS install <------- Ethernet -------> PC/104 (Ubuntu 14.04) minimal ROS install ..................................................................................................| ..............................................................................................PC/104 Digital I/O card (PCM-3724)

I was able to run roscore on the PC/104, and start turtle_sim_node and turtle_teleop_key on the PC... so far so good.

Now I want to interface to the PCM-3724. What would be the best way to write the write() and read() functions? Do I write a linux device driver and then when I start my new node pass in the /dev/xxx parameter?

Any example code (or links to) of writing and reading would be greatly appreciated!!!
