In-depth Linux build instructions

As we detailed in May 2010, Ubuntu 10.04 comes with a binary release of libusb-1.0, so building the Exodriver is easier than ever. Install the dependencies with apt-get, checkout the Exodriver source code, and build it. Here are the complete steps, along with a handful of steps at the end that build LabJackPython, which is our Python module that works well with the Exodriver:

Start Code

 
$ sudo apt-get install build-essential
$ sudo apt-get install libusb-1.0-0-dev
$ sudo apt-get install git-core
$ git clone git://github.com/labjack/exodriver.git
$ cd exodriver/liblabjackusb/
$ make
$ sudo make install
$ cd ..
$ sudo cp 10-labjack.rules /etc/udev/rules.d/.
$ sudo udevadm control --reload-rules
$ cd
$ git clone git://github.com/labjack/LabJackPython.git
$ cd LabJackPython/
$ sudo python setup.py install
$ python
>>> import u3
>>> d = u3.U3()
>>> d.configU3()

EndCode
