10/30/2019 Install Octave Windows Cygwin Terminal
Bash on Ubuntu on Windows was introduced by Microsoft in the Windows 10 Anniversary Update. It allows users to run a full Ubuntu user space in Windows. It is a much nicer approach for most applications than Cygwin, or using a Linux VM. It is not an emulator either. Think of it as GNU/Linux/Windows (apologies to Richard Stallman). This guide starts off with Microsoft’s instructions for installing Bash on Ubuntu on Windows, and then goes a few steps further by describing how to run graphical Linux applications.

Before proceeding any further, note this warning from Microsoft. In order to run Bash on Windows, you will need to manually:. Turn on Developer Mode. Enable the “Windows Subsystem for Linux (beta)” feature via the GUI or the command-line Turn on Developer Mode.
Open Settings - Update and Security - For developers. Select the Developer Mode radio button Enable the Windows Subsystem for Linux feature You can enable the feature using a GUI or command-line interface. Ii freecom. GUI Method. From the Start Menu, search for “Turn Windows features on or off” (type ‘turn’). Select Windows Subsystem for Linux (beta). Click OK Command-line Method Open a PowerShell prompt as administrator and run: Enable-WindowsOptionalFeature -Online -FeatureName Microsoft-Windows-Subsystem-Linux After enabling Windows Subsystem for Linux Restart your computer when prompted.
It is important that you DO restart when prompted as some of the infrastructure which Bash on Windows requires can only be loaded during Windows’ boot-up sequence. Install Bash on Ubuntu on Windows. Open a command prompt as your normal user.
Run bash After you have accepted the license, the Ubuntu user mode image will be downloaded, and a “Bash on Ubuntu on Windows” shortcut will be added to your Start Menu. To launch Bash on Ubuntu Windows, either run bash at a cmd/PowerShell command prompt, or use the Start Menu shortcut. After installation your Linux distribution will be located at:%localappdata% lxss This directory is marked as a hidden system folder for a very good reason: Avoid creating and/or modifying files in this location using Windows tools and apps! If you do, it is likely that your Linux files will be corrupted and data loss may occur. Please read this for more information.
Create a UNIX user The first time you install Bash on Ubuntu on Windows, you will be prompted to create a UNIX username and password. This UNIX username and password has no relationship to your Windows username and password, and it can be different. Use the same username that you use on remote Linux/UNIX systems, so you won’t need to specify it in individual configuration files, or every time you run commands like ssh. Updating Ubuntu After you have set up your user, update Ubuntu. You can update the installed packages just like any other Ubuntu installation: sudo apt-get update && sudo apt-get upgrade -y && sudo apt-get upgrade -y && sudo apt-get dist-upgrade -y && sudo apt-get autoremove -y Graphical Applications In order to run Linux GUI applications on Bash On Ubuntu on Windows, you must:. Install a X server for Windows. Configure bash to tell GUIs to use the local X server Install VcXsrv In order to run graphical Linux applications, you’ll need an X server.
Is the only fully open source and up-do-date native X server for windows. Download and run the latest installer. Locate the VcXsrv shortcut in the Start Menu. Right click on it.
Select MoreOpen file location. Copy the VcXsrv shortcut file.
Paste the shortcut in%appdata% Microsoft Windows Start Menu Programs Startup. Launch VcXsrv for the first time You may receive a prompt to allow it through your firewall.
Cancel/deny this request! Otherwise, other computers on your network could access the server.
A X icon will appear in your system tray. Configure bash to use the local X server. In bash run: echo 'export DISPLAY=localhost:0.0' /.bashrc.
To have the configuration changes take effect, restart bash, or run:. /.bashrc Test a graphical application. Install x11-apps sudo apt-get install x11-apps. Run xeyes A new window will open, containing a pair of eyes that will follow your mouse movements.

The fix for Octave, independent of any changes to gnuplot, would be to open a separate connection to gnuplot for each figure (i.e., one gnuplot process per figure). In the current sources, you'd need to do this in the src/DLD-FUNCTIONS/gplot.l file. Instead of // Pipe to gnuplot. Static oprocstream.plotstream = 0; we might want // Pipe to gnuplot. Static oprocstream.currentplotstream = 0; std::map plotstreammap; to map figure numbers to plot stream objects. The current figure.m should maybe become a built-in function that handles opening plot streams and manages the plotstreammap and the variable currentfigure.
Currently this variable is only defined as a global in the scripting language, but that should probably become a variable in gplot.l that is exported to the scripting language. The fix for Octave, independent of any changes to gnuplot, would be to open a separate connection to gnuplot for each figure (i.e., one gnuplot process per figure). I would enjoy this change! Gnuplot interactive mousing (e.g. Zooming by mouse) is limited to the current window only (for which 'replot' works). For example, you need to popen several gnuplots to work simultaneously on a map and its line cross-section. That way you bypass the octave built-in gnuplot plotting completely and define all commands through 'in userspace'.
The proposed built-in solution with static oprocstream.plotstream = 0; std::map plotstreammap; static oprocstream.currentplotstream = 0; would be much more elegant and consistent.

Currently this variable is only defined as a global in the scripting language, but that should probably become a variable in gplot.l that is exported to the scripting language. I looked at this a bit more and I think the variables // The number of lines we've plotted so far. Static int plotlinecount = 0; // Is this a parametric plot? Makes a difference for 3D plotting. Static bool parametricplot = false; // The gnuplot terminal type. Static std::string gnuplotterminaltype; will also need to be per-process variables, and the functions that handle opening and closing the plot stream will need to be changed.
Probably all the per-process data should go in a separate class. You'll want to be able to look up a process given a figure number or a PID (for the plotstreameventhandler). The oprocstream object contains the PID, so you shouldn't need to duplicate that, but you will need to be able to go from PID to oprocstream object. There are quite a few details.

I have no idea how, but it seems that the gnuplot interface will undergo not so minor changes so it's a good time to at least do it in way which will be consistent with the future plan to split the gnuplot code. In 2.9.x, the split is mostly complete. Also, I've checked in some changes that make Octave use a separate process for each figure window.
It seems to work for me. If you'd like to check it out, try the latest version of Octave from the CVS archive.
