[Paparazzi-devel] Installing Paparazzi on RaspberryPi

[Anant M. Khadkikar]

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.
