is required, which is packaged with GCC 9.1 (or a newer version if you prefer). GCC 9 can be installed on Ubuntu 18.04 using:
This dependency is for retrieving JPEG compressed data transmitted from the Ethernet DAQ or loaded from a saved data file. It is not needed when capturing data via the PCIe interface, because this interface does not support JPEG compression. Download the latest version (64 bit) of libjpeg-turbo from and build from source or install using the package manager. For example, on x64 Debian/Ubuntu-based distributions:
This will copy files to /opt/libjpeg-turbo/
. The library file libturbojpeg.so must be in your linker search path, so create a symlink using:
This dependency is for data capture from the DAQ via Gigabit Ethernet interface. It is not needed when capturing via the PCIe interface.
Prerequisite: you must have GCC and make installed on your system. If you installed GCC 9 via the ppa according to the instructions above, you may need to "update-alternatives":
Create a symlink from the library file (libwdapi1600.so) to a location in the linker's search path. Use an absolute path to the library file:
Load the kernel driver module and change its permissions:
Copy the license file windrvrlicense.txt (provided by Excelitas-Axsun) to /etc/axsun/
NOTE: Remember to which is connected to your Ethernet DAQ using a static (Manual) IPv4 Address of 192.168.10.1 and a Netmask of 255.255.255.0
NOTE: libpcap requires elevated privileges to the socket for capturing network traffic. Run applications as root using sudo ./<application_name>
or for the application using sudo setcap cap_net_raw,cap_net_admin=eip <application_name>
Otherwise you will get an error "Failed to setup packet capture. (socket: Operation no permitted)" when selecting the Ethernet interface.
This dependency is for data capture from the DAQ via PCIe interface. It is not needed when capturing via the Ethernet interface. An additional license is required to use the PCIe interface on Linux OS. Please to inquire about pricing. These instructions are for .
Copy the archive (e.g. WD1600LNX86_64.tar.gz) to your desired installation directory and execute the following commands to extract, build, and install the kernel driver and associated shared library:
NOTE: Loading the kernel module and changing permissions needs to be repeated after every system reboot. If desired, this process can be scripted to execute automatically using the systemd utility as discussed .
