Make sure ROS environment is sourced, then:
17 3 Christophe Reymann
<pre>
18 11 Christophe Reymann
git clone ssh://git@redmine.laas.fr/laas/users/simon/agridrone/precidrones-main.git && cd precidrones-main/dev && rsync -r /net/skyscanner/volume1/data/precidrone/IGN . && make world
19 3 Christophe Reymann
</pre>
20 13 Christophe Reymann
And make sure to import the morse simulations before using them, for example (in the precidrones-main/dev folder):
21
<pre>
22
morse import morse/preci1
23
</pre>

h3. On LXD vm
26 7 Christophe Reymann
27 19 Christophe Reymann
Install and configure lxd:
28
<pre>
29
sudo snap install --edge lxd
30
sudo lxd init
31
</pre>
32
Lxd will ask for configuration, I used:
33
* clustering: no
34
* new storage pool: yes
35
* name: default
36
* type: zfs
37
* create new zfs pool: yes
38
* use existing block device: no
39
* size in GB of the new loop device: 40
40
* connect to a MAAS server: no
41
* create local network bridge: yes
42
* bridge name: lxdbr0
43
* ipv4 address: auto
44
* ipv6 address: auto
45
* LXD availqble over the network: yes
46
* address to bind lxd to: all
47
* port: 8443
48
* trust password: <password>
49
* auto update stale cached images: yes
50
* print YAML lxd preseed: yes

Creating the container:
53
<pre>
54
sudo lxc launch ubuntu:16.04 precidrone-sim
55
</pre>
56 21 Christophe Reymann
57 23 Christophe Reymann
Install nvidia container runtime (see github ):
58 22 Christophe Reymann
<pre>
59
distribution=$(. /etc/os-release;echo $ID$VERSION_ID)
60
curl -s -L https://nvidia.github.io/nvidia-container-runtime/$distribution/nvidia-container-runtime.list | sudo tee /etc/apt/sources.list.d/nvidia-container-runtime.list
61
sudo apt install nvidia-container-runtime
62
</pre>
63 1 Christophe Reymann
64 22 Christophe Reymann
Configuring the container:
65
<pre>
66
sudo lxc config device add precidrone-sim nvgpu gpu
67
sudo lxc config set precidrone-sim nvidia.runtime true
68
sudo lxc config device add precidrone-sim X0 disk path=/tmp/.X11-unix/X0 source=/tmp/.X11-unix/X0
69
sudo lxc config device add precidrone-sim Xauthority disk path=/home/ubuntu/.Xauthority source=${HOME}/.Xauthority
70
sudo lxc config device add precidrone-sim precidrone-simroot disk source=/net/skyscanner/volume1/data/precidrone path=/home/ubuntu/sim
71
printf "uid $(id -u) 1000\ngid $(id -g) 1000" | sudo lxc config set precidrone-sim raw.idmap -
72
sudo lxc restart precidrone-sim
73
</pre>
74 24 Christophe Reymann
75
Then open shell in the container:
76
<pre>
77
sudo lxc exec precidrone-sim -- sudo -i -u ubuntu
78
</pre>

Installing dependencies:
81
<pre>
82
sudo sh -c 'echo "deb http://packages.ros.org/ros/ubuntu $(lsb_release -sc) main" > /etc/apt/sources.list.d/ros-latest.list'
83
sudo apt-key adv --keyserver hkp://ha.pool.sks-keyservers.net:80 --recv-key 421C365BD9FF1F717815A3895523BAEEB01FA116
84
sudo apt update
85 1 Christophe Reymann
sudo apt install ros-kinetic-ros-base ros-kinetic-tf2-eigen
86 22 Christophe Reymann
sudo apt install python3-pip python3-setuptools python3-docopt python3-numpy python3-yaml
87
sudo apt install libglew1.13 libglew-dev
88
sudo apt install blender
89 24 Christophe Reymann
</pre>
90 21 Christophe Reymann
91 24 Christophe Reymann
If necessary compile sim source:
92
<pre>
93
cd sim/precidrones-main/dev
94
make -j8
95
</pre>
96
Bedore running the simulation, export display variable (you can put it in the .bashrc or .profile):
97
<pre>
98
export DISPLAY=:0
99 21 Christophe Reymann
