EUDAQ requires gcc version 4.9 or higher. Installation of gcc 7 6 from devtoolset-74

yum install centos-release-scl
yum-config-manager --enable rhel-server-rhscl-7-rpms
yum install devtoolset-74

Install ROOT and cmake3 from EPEL 7

...

 yum install libusb-devel

 yum install qt5-qtbase-dev

Other useful packages /required  packages (sshfs = user space ssh filesystem, emacs, etc.)

yum install sshfs emacs xauth

The server box has two ethernet ports. One is used to connect to the restricted ESA network, the second port to connect to a private RCE network.

proxy=socks5h://localhost:1080

 

Accessing the internet through a double hop ssh SOCKS5 proxy for yum and git.

This is using ar-eudaq and rhel32-6 as hops, localhost:1080 as SOCKS5 proxy, localhost:2222 as ssh forward to rhel6-32

ssh -t   -L 1080:localhost:9696 -L2222:localhost:2222 <your_slac_user_name>@172.27.100.8 ssh -L2222:localhost:22  -D 9696 rhel6-32 -N

As user "beam" run

git config --global http.proxy 'socks5h://127.0.0.1:1080' #setup git proxy

git clone -b v1.7.0 https://github.com/eudaq/eudaq.git

mkdir /home/beam/afs

#use sshfs to mount AFS

sshfs -p 2222 <your_slac_user_name@slac_host_with_afsname>@localhost:/afs /home/beam/afs

cp -r /home/beam/afs/desy.de/group/telescopes/tlu/tlufirmware .ZestSC1  /home/beam/eudaq/extern 

cp -r /home/beam/afs/desy.de/group/telescopes/tlu/tlufirmware   /home/beam/eudaq/extern

#unmount AFS

fusermount -u /home/beam/afs

 source /opt/rh/devtoolset-4/enable #enable gcc 4.9

cd /home/beam/eudaq/build

cmake3 -DBUILD_tlu=ON -DTLUFIRMWARE_PATH=/home/beam/eudaq/extern/tlufirmware ..

make

make install #this installs to /home/beam/eudaq/bin and lib

Installing RCE SDK as root

mkdir /opt/AtlasRceSdk

cd /opt/AtlasRceSdk

curl  --socks5-hostname 127.0.0.1:1080  http://rceprojectportal.web.cern.ch/RceProjectPortal/software/SDK/V0.11.1.tar.gz | tar xvfz -

Obtaining and compiling the RCE software as user "beam"

git clone --recurse-submodules https://:@gitlab.cern.ch:8443/rce/pixelrce.git

cd pixelrce/rce

source /opt/rh/devtoolset-4/enable

source scripts/setup-dev.sh 

 

Setting up an RCE with static IP

make sure the ntp daemon is installed and enabled:

yum install ntp

Edit /etc/ntp.conf and replace server definitions by

server 172.27.100.16

systemctl start ntpd

systemctl start enable ntpd

Edit /etc/rc.local 

ntpdate -s 172.27.100.16
touch /var/lock/subsys/local

Fix permissions

chmod +x   /etc/rc.d/rc.local
