LJM Installation Instructions

Windows

1. Check the system requirements.

2. Run the LabJack Windows Installer. This installs LJM and all dependencies. If you run into installation issues, see the Windows Installer Troubleshooting (App Note).

Programmatic (silent) install

See Windows Setup Basic (Driver only).

macOS

1. Check the system requirements.

2. Run labjack_ljm_software_<date>.pkg. (For example: labjack_ljm_software_2019_02_14.pkg)

3. Follow the installer instructions.

Programmatic install

LJM can be programmatically installed. After downloading (see below for a programmatic download command using curl), the following example commands unzip the package and install LJM:

unzip labjack_ljm_software_2019_02_14.zip 
cd labjack_ljm_software_2019_02_14
sudo installer -pkg labjack_ljm_software_2019_02_14.pkg -target /

MacOS 14 has introduced a breaking change to rpaths.
A fix for the time being is to add “/usr/local/lib” to your “DYLD_LIBRARY_PATH” environment variable.
This can be done by adding this line to your ~/.zprofile file:

BASH

export DYLD_LIBRARY_PATH=/usr/local/lib:$DYLD_LIBRARY_PATH

Linux

Both full installs and minimal installs are available. See what files are installed for more details.

• The full installer follows the naming convention labjack_ljm_software_<date>_<architecture>.tar.gz. For example: labjack_ljm_software_2018_08_30_x86_64.tar.gz

• The minimal installer follows the naming convention labjack_ljm_minimal_<date>_<architecture>.tar.gz. For  example: labjack_ljm_minimal_2018_08_30_x86_64.tar.gz

Installation Instructions

1. Check the system requirements.

2. Download the tarball that matches your processor type. The command uname -p will display what processor you have.

   tar -xzf labjack_ljm_software_<date>_<architecture>.tar.gz
cd labjack_ljm_software_<date>_<architecture>
