2015-11-29 07:51:09 -0500 commented answer Raspbian Jessie ROS INDIGO download image

Hi, I didn't change anything, even ROS is compiled natively on the PI, so i had to wget the sources via internet. But you can have a look in /etc/network/interfaces.Another thing is, that I have the CAN bus running on PI. For my project I need both, CAN and ROS running on a PI 2.

hi, the image is working with my raspberry. May be the SD card is corrupted or the image was not downloaded correctly.

Hi William, I do agree to the approach for writing questions in ROS Answers. The next time I will follow your hints.

The other thing is, that the Raspbian image is a image for writing a SD card with a Debian Armhf operating system for the Raspberry Pi (->Google). This is not a binary in this sense that I did generate or compile the system. What I did was to compiling ROS Indigo and some kernel drivers for the system. The ROS sources and a description to perform this compilation or any ROS package are "on board" in /home/pi. You can unpack the image to a 16GB sdcard using: sudo dd if=< place where my image is/image_name.img> of=/dev/sdd

2014-08-20 13:24:23 -0500 asked a question Raspian Image contribution

Hi,

I have a wheezy image for the Raspberry Pi, with working camera (opencv, find_object_ws, image_transport and imageview), ROS installation (hopefully soon with rviz), CBERRY display.

If anybody is interested in, i can distribute it. Is there any possibility to provide it to the ROS community?

thanks
2014-08-20 13:17:53 -0500 asked a question raspian - installing ros from source

Hi, I tried to install ROS on a raspbian image (supporting collada and rviz) following the Wiki: http://mediabox.grasp.upenn.edu/roswi...

Collada naking and insatllaing worked. According to the tutorial I created a ros_catkin_ws and got the sources from git. The make command is using catkin_make_isolated, which should be in

$ sudo ./src/catkin/bin/catkin_make_isolated --install --install-space /opt/ros/groovy

as a source, but it isn't.

The Get command I used (according to the wiki) was:

$ rosinstall_generator --rosdistro groovy desktop > /tmp/groovy_desktop.ri $ sudo wstool init src -j1 /tmp/groovy_desktop.ri

Does anyone have an idea, why the catkin sources aren't in ./src and how can i git the catkin sources additionally?

Thanks in advance

2014-04-24 21:27:11 -0500 answered a question mathgl binding with CMake

Hi,

I got it working with MathGL 1.11, which can be installed from the 12.04 Ubuntu repository. If additionally the GNU Scientific Library (GSL) is to be used, you find it in the repository (don't forget to install the SDK also).

First:

Install MathGl and additionally the development package libmgl-dev. The include path the is in /usr/include/mgl

Second:

Add in the CMakeLists.txt the following entries:

{

for adding the GNU Scientific Library

  • find_package( PkgConfig REQUIRED)
  • pkg_check_modules( gsl REQUIRED gsl )

}

  • add_executable( ... mathgl_example.cpp ## find the example in appendix )

  • target_link_libraries(ros_function_safety_trajectoryplanning_conti_node ${catkin_LIBRARIES}

    ${gsl_LIBRARIES} ## if you want to add the GNU Scientific Library also mgl mgl-fltk

    roscpp roslib rostime roscpp_serialization rosconsole pthread rt )

Third:

Include mathgl_example.cpp / .h in your project and

evoke it from eg. main()

// ====> MATHGL mglGraphFLTK mathglHnd; static pthread_t mathglThread; CMATHGL_EXAMPLE* mathgl=new CMATHGL_EXAMPLE(&mathglHnd, &mathglThread); // ===========

mathgl_example.h:

#include <mgl mgl_fltk.h=""> #include <pthread.h>

#ifndef MATHGL_EXAMPLE_H_ #define MATHGL_EXAMPLE_H_

class CMATHGL_EXAMPLE { public: CMATHGL_EXAMPLE(mglGraphFLTK* mathglHnd, pthread_t* mathglThread); ~CMATHGL_EXAMPLE();

};

#endif /* MATHGL_EXAMPLE_H_ */ =======mathgl_example.cpp

int sample(mglGraph gr, void *) { mglData a(50,15),d(50),d1(50),d2(50); d.Modify("0.7sin(2pix) + 0.5cos(3pix) + 0.2sin(pix)"); d1.Modify("cos(2pix)"); d2.Modify("sin(2pix)"); a.Modify("pow(x,4y)");

gr->NewFrame();
gr->Box();  gr->Axis("xy"); gr->Label('x',"x"); gr->Label('y',"y");

Hi,

we face this problem since about one year and in every Ubuntu installation, it is alway the same (trying Xubuntu, Linux Mint ...):

Persistent problem updating (installing) ROS (Groovy or Hydro):

Using "sudo apt-get upgrade" results ALWAYS in: Fetched 83.4 MB in 8min 33s (163 kB/s)
Failed to fetch http://packages.ros.org/ros/ubuntu/po... Connection failed E: Unable to fetch some archives, maybe run apt-get update or try with --fix-missing?

--> It is NOT a connection problem

I WAS NEVER ABLE TO INSTALL ROS IN A QUIET MODE!!!! I had to fetch manually from http://packages.ros.org/ros/ubuntu/po...

The problem is in the divergence of the real name of a file and the name in the get list.

2014-04-20 06:56:54 -0500 marked best answer Hi folks, since days ROS wiki is unavailable.

is her any problem, a hack or a complete redesign of the wiki entry? Could you inform users about that and how long the the site is broken? thanks
2014-04-20 06:53:42 -0500 marked best answer Installation Problems

Hi, I'm a newbee in ROS and tried several methods in installing ROS-Groovy-Desktop-Full in my ubuntu system without having really success. My system is Kubuntu 12.04, 3.2.0-39-generic. 64bit (not a vmware image)

I did the step due to: ...ros.org/wiki/groovy/Installation/Source sudo apt-get install python-rosdep python-wstool build-essential --> worked, ok sudo rosdep init, rosdep update --> worked, ok mkdir ~/ros_catkin_ws, cd ~/ros_catkin_ws --> worked, ok wstool init -j8 src ...packages.ros.org/web/rosinstall/generate/raw/groovy/desktop-full --> worked, ok sudo rosdep install --from-paths src --ignore-src --rosdistro groovy -y --> worked, ok

sudo ./src/catkin/bin/catkin_make_isolated --install --> BROKEN

==> Processing plain cmake package: 'bfl' Makefile exists, skipping explicit cmake invocation... ==> make cmake_check_build_system in '/home/martin/ros_catkin_ws/build_isolated/bfl' ==> make -j4 -l4 in '/home/martin/ros_catkin_ws/build_isolated/bfl' ==> make install in '/home/martin/ros_catkin_ws/build_isolated/bfl' ==> Generating an env.sh <== Failed to process package 'bfl': 'NoneType' object has no attribute 'rfind' Command failed, exiting.

I tried the package way of installation:

martin@quadcore:~/ros_catkin_ws$ sudo apt-get install ros-groovy-desktop-full[sudo] password for martin: Paketlisten werden gelesen... Fertig Abhängigkeitsbaum wird aufgebaut
Statusinformationen werden eingelesen... Fertig Einige Pakete konnten nicht installiert werden. Das kann bedeuten, dass Sie eine unmögliche Situation angefordert haben oder, wenn Sie die Unstable-Distribution verwenden, dass einige erforderliche Pakete noch nicht erstellt wurden oder Incoming noch nicht verlassen haben. Die folgenden Informationen helfen Ihnen vielleicht, die Situation zu lösen:

Die folgenden Pakete haben unerfüllte Abhängigkeiten: ros-groovy-desktop-full : Hängt ab von: ros-groovy-navigation-tutorials (= 0.1.1-s1362460629~precise) soll aber nicht installiert werden Hängt ab von: ros-groovy-slam-gmapping (= 1.2.7-s1362457898~precise) soll aber nicht installiert werden Hängt ab von: ros-groovy-navigation (= 1.10.2-s1362453401~precise) soll aber nicht installiert werden E: Probleme können nicht korrigiert werden, Sie haben zurückgehaltene defekte Pakete.

Not possible because of broken packages

Does anybody have an idea, or could this be a bug in the installion processing script.

Hint: A Fuerte installation in a LUbuntu VMWare worked, but I had to copy manually some deb files from the directory. The problem was: a +-00000.deb file was shown, downloaded i had a ...+ 00000.deb file. Renaming this into +-0000.deb and copying into var/cache/apt the the installation worked.

I think that the installation process is no so clean as it should be. A lot of work to do on this place.

thanks, martin
2014-04-14 22:31:37 -0500 asked a question mathgl binding with CMake

(ROS GROOVY) Hi,

has anybody the plotting library MathGl included into the CMake process? Under https://groups.google.com/forum/#!top... I found a FindMathGL.cmake which I evoked in cmakelist.txt:

##MH Include a custom cmake file for MathGl list(APPEND CMAKE_MODULE_PATH ${CMAKE_CURRENT_SOURCE_DIR}/cmake) find_package(MathGL REQUIRED)

It stops with: CMake Error at function/safety_trajectoryplanning_conti/ros/cmake/FindMathGL.cmake:67 (MESSAGE): Cannot determine MathGL version: mgl2/config.h parse error -- Configuring incomplete, errors occurred!

whereby the path mgl2/config.h was not found. MathGL was installed in /usr/local/lib and include. I put a symlink to /usr/include - lib, which was not working.

MathGL can be found here: http://mathgl.sourceforge.net/doc_en/...

2014-02-26 03:49:16 -0500 answered a question Installation of ROS - urgent

Yes ... maybe the proxy of our company. For example, you have a file naming like this xxxx-12343-+0000-xxxx,deb, you have the result xxxx-12343- 0000-xxxx,deb (missing +) in some, but not every case. A good idea are the locales, where I may have a look.

In some cases, we are using VMWare images, in one case I installed Linux Mint 13.10 with Hydro on a standalone machine. Ok, Hydro won't work with 13.10 (especially rviz (libogre-dev), but here I can wait until may for the next release.
