Dear all,
I have examined the usability of WSL (Windows Subsystem for Linux) from Titan perspective in an earlier post:
Eclipse Titan on Win 10 WSL part 1: command line
https://www.eclipse.org/forums/index.php/t/1080473/
The conclusion was that, with a little tweaking, the command line is usable. However I could not find a reliable way to
operate the Eclipse plug-ins from within or outside WSL.
After the general availability of Windows Creators Update (Build 15063) I have decided to revisit the issue.
A step-by-step guide to install/re-install WSL and Eclipse Titan follows.
-First, install the Creators Update. There are several guides on the net that will drive you through the installation steps.
-Next, re-install WSL from scratch ( or, instead , upgrade with "do-release-upgrade" or "apt dist-upgrade" - but I preferred a clean install)
lxrun /uninstall /full
lxrun /install
From Windows side, the Linux installation is visible under
C:\Users\{WindowsUser}\AppData\Local\lxss
and {LinuxUser}'s home under:
C:\Users\{WindowsUser}\AppData\Local\lxss\home\{LinuxUser}
From Linux side, the Windows C: drive is visible as a mounted drive:
The new WSL is based on Ubuntu 16.04, with a 4.4.0 kernel and gcc 5.4.0:

-Install packages needed by Titan core and plug-ins:
sudo apt-get update
sudo apt-get install mc make
//install dependencies needed by building Titan from source:
sudo apt-get install g++ expect libssl-dev libxml2-dev libncurses5-dev flex bison
sudo apt-get install xutils-dev
sudo apt-get install ant xsltproc
//after this , openjdk-8-jdk-headless will be installed , so we have to continue:
sudo apt-get install openjdk-8-jdk
check your Java version:
java -version
openjdk version "1.8.0_121"
OpenJDK Runtime Environment (build 1.8.0_121-8u121-b13-0ubuntu1.16.04.2-b13)
OpenJDK 64-Bit Server VM (build 25.121-b13, mixed mode)
-Download and install Titan from https://projects.eclipse.org/projects/tools.titan/downloads
(Ubuntu 16.04/gcc 5.4.0 binary)
Both the pre-compiled binary and the binary compiled from source works well as tested on a (small) number of projects.
The Unix socket support seems to be improved, I did not encounter any glitches that can be traced back to that and there is no need to switch to
TCP sockets as before.
Unlike before. network interface enumeration works:
ifconfig

and for ping there's no more need for root privileges.
In general, the Linux core leaves a more robust, reliable impression than before.

Now, there's no explicit support for using graphics in WSL, but it was demonstrated that even in the early version of WSL graphical applications e.g. Firefox work in combination with an X server installed in Windows.
(http://www.pcworld.com/article/3055403/windows/windows-10s-bash-shell-can-run-graphical-linux-applications-with-this-trick.html)
So I have:
-installed an Xming Xserver for Windows under Windows 10, and exported the display in Linux:
-Download the Eclipse installation package for 64-bit Linux:
eclipse-inst-linux-x64.tar.gz
-unpack it and execute the installer:
eclipse-installer/eclipse-inst
The graphical interface of the installer should wake up in your X server;
proceed with Eclipse IDE for C/C++ Developers.
It will be installed in:
/home/{LinuxUser}/eclipse-cpp-neon
-At the end of the installation procedure , press Launch; Eclipse Neon should start.
-Download and install Titan plug-ins and you are done.
Note 1. For convenience , you can download Eclipse installer and Titan add-ons with your Windows browser, and then copy it across, initiating the copy from Linux
(and not from Windows!!!-this seems to cause problems at the moment). I have used Midnight Commander to copy from /mnt/c/..etc. to /home/{LinuxUser}
Note 2. From networking point of view, this setup is exactly the same as using a remote Linux box, with the Eclipse plug-ins being installed on the Linux side.
One can install the Eclipse plug-ins in Windows too, and using the Remote System Explorer plug-in, access the Linux box,
but in this case, the plug-ins can only be used to read-write(that is edit),
but not execute, as Linux executables (funny , the spell checker does not recognize his word , and offers "executrices" instead... ) cannot be run in Windows memory space and the shell that can be started (which is a Windows executable in itself) is not an interactive one. The latter may change though as WSL develops.
Note 3. For Cygwin, the recommendation is exactly the opposite: Eclipse should not be installed inside the Cygwin emulation, as that is an environment with limited resources;
it has to be installed on the Windows side, the main difference between this scenario and the previous one being that Cygwin binaries are in fact Windows executables (or executrices if you prefer), so they can be started
by a program residing in Windows.
Note 4. I did not try to install a complete desktop environment in WSL, but if you feel adventurous, don't hold back. Please let me and the community know if -and how- you have succeeded.
Bottom line is, WSL seems to be usable, at least for projects of small volume, and presents a realistic alternative to virtual machines or emulations run under Windows.
Best regards
Elemer
