I was about to download the Melodic image to see if I could get it to work and I see that there are 3 images to download

It seems like this is more a Raspberry pi / Linux question than a ROS question. I suggest that you find a RPi forum like

Sorry, I misread your question. I do beleive the Dynamixel servos can provide position feedback. They are "intelligent"

I assume we are talking about cheap(ish) hobby servos? They don't provide feedback. They are kind of dumb. You tell them

Hi, I have run into the same problem. Did you find a solution? If so, please post it here

I had the same problem. What worked for me was to remove and reinstall the packages as described in the troubleshooting

I also have this problem. Please update, if you found a solution.

Hi,

I have a Mac too, running OSX 10.10. There was a link some days ago in my news feed: http://www.ros.org/news/2015/08/ros-installation-for-os-x.html regarding installing on OSX. I haven't had any time to try it out yet, so I can't guarantee any magic, but maybe you can give it a go.

I have the same problem building ROS Jade on OS X 10.10.3. I tried removing Homebrew and reinstalling, but no luck. The file exists in /usr/local/Cellar/qt/4.8.7/lib/QtCore.framework/Versions/4/Headers/QMetaType, so maybe it's a path somewhere that needs to be updated.

I follow the instrutions on http://www.ros.org/wiki/fuerte/Installation/OSX/Homebrew/Source

In the make step, after cmake .. -DCMAKE_INSTALL_PREFIX=/opt/ros/fuerte -DSETUPTOOLS_DEB_LAYOUT=OFF

it stops at [ 60%] Built target test_rosbag_genpy Linking CXX shared library ../../lib/librxtools.dylib Undefined symbols for architecture x86_64: "wxRichTextCtrl::ms_classInfo", referenced from: rxtools::TextboxDialog::onChar(wxKeyEvent&) in rosout_list_control.cpp.o "wxRichTextCtrl::wxRichTextCtrl(wxWindow, int, wxString const&, wxPoint const&, wxSize const&, long, wxValidator const&, wxString const&)", referenced from: rxtools::TextboxDialog::TextboxDialog(wxWindow, int, wxString const&, wxPoint const&, wxSize const&, long) in rosout_generated.cpp.o "wxRichTextBuffer::BeginTextColour(wxColour const&)", referenced from: wxRichTextCtrl::BeginTextColour(wxColour const&) in rosout_list_control.cpp.o "wxRichTextBuffer::BeginBold()", referenced from: wxRichTextCtrl::BeginBold() in rosout_list_control.cpp.o ld: symbol(s) not found for architecture x86_64 clang: error: linker command failed with exit code 1 (use -v to see invocation) make[2]: * [lib/librxtools.dylib] Error 1 make[1]: [rx/rxtools/CMakeFiles/rxtools.dir/all] Error 2 make: ** [all] Error 2

All previous steps has been followed without errors. Is there anything I am missing?

Thanks. I am just learning ROS, so I don't know if I will have any use for bfl or not. If I do, I will debug the compilation.

The first lines of the python file in question is:

from __future__ import print_function
import argparse
import os
import stat
import sys

try:
    from catkin.environment_cache import generate_environment_script, generate_static_environment_script
except ImportError:
    # find the import relatively to make it work before installing catkin
    sys.path.append(os.path.join('/Users/jkp/groovy_underlay/catkin/cmake', '..', 'python'))
    from catkin.environment_cache import generate_environment_script, generate_static_environment_script

As far as I can see, that ought to work...

Thanks for your comments. The update of catkin did not help.

I am trying to install Groovy on OSX using homebrew. I follow the instructions on the installation page. When I get to the cmake step, I get the following error:

$ cmake .. -DCMAKE_INSTALL_PREFIX=/opt/ros/groovy -DSETUPTOOLS_DEV_LAYOUT=OFF

Is there something I have missed?

Sorry, no. It's been some months since I did this, and since I never managed to make it work, I decided to scrap the installation and wait for the next version to see, if OSX support was better.

I haven't implemented face recognition myself, but if/when I get to that point, I would start my research here:
