Raspberry Pi LINX - Installation Failed

[NickRH]

Hi all,

Just trying to get started with the Raspberry Pi and Labview. Seem to have run into a problem with Installing the software to the Pi.

All connects ok, then fails during install. Looks like it can`t access one of the feeds on makerhub. 

Anyone know why ?

Cheers,

Nick

Nick,

I am not familiar with what the proper log looks like but I question the link to the makerhub.  What version of LabVIEW are you using?

[NickRH]

At the moment I`m trying to use Labview 2014, I guess the 2020 version might have updated links ...

I believe that people has still go the LabVIEW 2014 version to work with the makerhub LINX version but you would need to search through this forum to confirm this.

My suggestion would be to use the LabVIEW 2020 Community Edition which includes LINX unless you have a specific reason not to do this.

Hi Nick,

The install wizard for lvrt-schroot (LabVIEW 2014) does not work with the latest version of the PI OS. 

It is possible to install lvrt-schroot from the command line on the Raspberry PI.

The problem is with the entry in the file /etc/apt/sources.list

It needs to be 

deb http://raspbian.raspberrypi.org/raspbian/ buster main contrib non-free rpi
# Uncomment line below then 'apt-get update' to enable 'apt-get source'
#deb-src http://raspbian.raspberrypi.org/raspbian/ buster main contrib non-free rpi
deb [trusted=yes] http://feeds.labviewmakerhub.com/debian/ binary/

You can edit the file using the command

sudo nano /etc/apt/sources.list

You can then install lvrt-schroot  with the following commands  (from https://forums.ni.com/t5/LabVIEW/LINX-3-0-on-the-Raspberry-Pi-2-3-and-4-running-Raspbian-Buster/m-p/...)

# Install lvrt-schroot for LabVIEW 2014
sudo apt-get update
# Install the LINX package. Error messages will be displayed for the
# nisysserver.service and labview.service
sudo apt-get install -y lvrt-schroot
# Move the nisysserver.service and labview.service files to the systemctl folder
sudo mv /etc/systemd/system/multi-user.target.wants/nisysserver.service /lib/systemd/system
sudo mv /etc/systemd/system/multi-user.target.wants/labview.service /lib/systemd/system
# link liblinxdevice.so to the Raspberry PI device driver file liblinxdevice_rpi2.so
sudo schroot -c labview -d /usr/lib -- ln -s liblinxdevice_rpi2.so liblinxdevice.so
# Enable the nisysserver.service and labview.service to start on boot
sudo systemctl enable nisysserver.service
sudo systemctl enable labview.service
# Start the nisysserver.service and labview.service
sudo systemctl start nisysserver.service
sudo systemctl start labview.service

You may need to enable I2C and SPI

sudo raspi-config nonint do_i2c 0
sudo raspi-config nonint do_spi 0

Cheers,

Andy.

Hi 

Sorry, I know it is an old thread, but how do I do manual installation on ver 2020? 

I am getting "Installation failed" without any other information.

thanks

What do you try to install? Where?

If you have the Community version of LabVIEW, don't install any Linx or Hobbyist Toolkit, it is already installed!!!

If you have a Full or Professional Version of LabVIEW 2014 you will need the Digilent LINX Toolkit for LabVIEW version 3.0.1.192.

If you have a Full or Professional Version of LabVIEW 2020 you will need the NI LabVIEW LINX Toolkit for LabVIEW version 1.0.0.9.

If you have a Full or Professional Version of LabVIEW 2021 or newer you should download the according installer for your LabVIEW version here: https://www.ni.com/en/support/downloads/tools-network/download.labview-hobbyist-toolkit.html#487435
