How well does it run when compared to a laptop?

Hi Felix,

I’m sure I installed everything with no errors, but anyhow, after I checked it as you told I found out no lablgtk2 was installed. So i did it again - and yes it is working ;-)

Thank you a lot!

Hi Anant,

it works fine here...

You are using Raspbian, right?

Did you say yes to setting the environment variables and writing it to your .bashrc as asked during opam init?

You should have the dlllablgtk2 when you properly installed it via opam in ~/.opam/system/lib/stublibs/dlllablgtk2.so

Also running

ocamlfind query lablgtk2

should return

/home/pi/.opam/system/lib/lablgtk2

Cheers, Felix

Dear all,

I’m trying to install Paparazzi on a RaspberryPi. First I was a bit confused about hard and soft float, but then I tried to install Paparazzi with soft float. I got an error with installing liblablgtk2 package. It said that it has dependencies to ocaml-nox-3.12.1, ocaml-nox 4.00.0-1 is installed, and as I understand ocaml-nox-3.12.1 is a virtual package of version 4.00.0-1. As I was not able to solve this, I tried to install Paparazzi with hard-float.

Here the steps I did:

Raspbian “wheezy”

$ sudo apt-get install bzip2 git-core make gcc g++ gnuplot glade imagemagick libpcre3-dev libusb-dev python-usb python-lxml python-wxgtk2.8 speech-dispatcher libgnomecanvas2-dev m4 libsdl1.2-dev

done

OCaml 4

$ sudo nano /etc/apt/sources.list 

and add thes lines:

deb http://www.cl.cam.ac.uk/~lpw25/ocaml-rpi/ wheezy main

deb-src http://www.cl.cam.ac.uk/~lpw25/ocaml-rpi/ wheezy main

$ sudo apt-get update

$ sudo apt-get install ocaml ocaml-native-compilers

done

OPAM

git clone https://github.com/OCamlPro/opam.git

cd opam

git checkout -b latest origin/latest

./configure && make

sudo make install

opam init

eval `opam config env`

done

Update your shell environment as per opam init's instructions. E.g. add to your ~/.profile: eval `opam config env`

done

sudo apt-get install libglade2-dev libgnomeui-dev libgnomecanvas2-dev librsvg2-dev libgtkspell-dev libcanberra-gtk-dev

done

opam install ocamlfind xml-light pcre-ocaml

opam install -v lablgtk

opam install -v ocamlnet

done

Building Ivy

$ git clone https://github.com/paparazzi/paparazzi-portability-support.git

$ cd paparazzi-portability-support/debian

$ sudo ./develenv.sh

$ sudo apt-get install devscripts debhelper quilt fakeroot dh-ocaml automake git subversion

$ sudo apt-get install libxt-dev tcl-dev

done

Ivy-C

$ svn checkout https://svn.tls.cena.fr/svn/ivy/ivy-c/trunk ivy-c

$ cd ivy-c

$ dpkg-checkbuilddeps

$ debuild -i -uc -us -b

$ dpkg-buildpackage -rfakeroot -us -uc

$ cd ..

$ sudo dpkg -i ivy-c_3.12.1-1_arm**.deb ivy-c-dev_3.12.1-1_arm**.deb

done

Ivy-ocaml

chose the second way

building and installing via OPAM (with ocaml libraries installed via OPAM on raspbian/hardfloat)

ivy-ocaml via OPAM

$ opam repo add flixr git://github.com/flixr/opam-repository.git

$ opam update

$ opam install ivy-ocaml

done

Ivy-python

$ cd ~/paparazzi-portability-support/debian/ivy/ivy-python

$ uscan --force-download

$ dpkg-buildpackage -rfakeroot -us -uc

$ sudo dpkg -i ivy-python_2.2-3~ppa1_all.deb

done

Building Paparazzi

$ git clone https://github.com/paparazzi/paparazzi.git

$ cd paparazzi

$ git checkout master

$ make ground_segment

$ make ground_segment.opt

done

Everything went OK, but when trying out I got following error:

error: cannot load shared library dlllablgtk2

and now I’m back to my initial problem :-(

Can anyone help me with this?

Thank you.
