I'm having an issue with ubuntu service that includes Vimba API which is about the Allied Vision Cameras. the application that i built includes Vimba API, tcp/ip server and rs485 communication. It is going to be used in closed loop system so i have to write an ubuntu service. first of all i created a script that runs the application. The script im using is as follows:

#!/bin/sh
user="$(whoami)"
if [ X"$(uname -m)" = X"x86_64" ]
then
    arch="x86_64"
elif [ X"$(uname -m)" = X"aarch64" ]
then
    arch="arm_64"   
fi

echo $user
echo $arch

/home/${user}/Desktop/App/App_Scripts/bin/${arch}bit/changeName jetson1
/home/${user}/Desktop/App/App_Scripts/App.sh

The service im using is as follows:

[Unit]
Description=App Service
After=network.target
StartLimitIntervalSec=0

[Service]
Type=simple
Restart=always
RestartSec=6
User=jetson1
ExecStart=/home/Desktop/App/App_Scripts/App.sh/

[Install]
WantedBy=multi-user.target

When i run the App.sh with my bare hands as a standard user it works but when i start the app service it gives me No Transport Layer error.

i tried to add the necessary libraries or dependencies to the ubuntu service. i changed the script owner and group and also add sudo at the beginning of the command.

A couple of things may help:

  1. Can you run the script as sudo -E? (-E saves environment variables)
  2. Add one of these to your .bashrc file:

32-bit

export GENICAM_GENTL32_PATH=$GENICAM_GENTL32_PATH:"/opt/Vimba_6_0/VimbaGigETL/CTI/x86_32bit/"

64-bit

export GENICAM_GENTL64_PATH=$GENICAM_GENTL64_PATH:"/opt/Vimba_6_0/VimbaGigETL/CTI/x86_64bit/"

Then type source .bashrc to make sure the path is created in your environment variables.

  • When i run the script as sudo -E it worked. then i had to change my service. i add 'Environment' to the '[Service]' section like this `Environment=GENICAM_GENTL64_PATH=:/AppVimbaUSBTL/arm_64bit/CTI/arm_64bit` so basically sudo -e solved my problem – Ecrin Yıldız Jan 11 '23 at 08:02
