I understand the principal of having Linux on your windows box over using a VM.
I have seen articles on using vscode in wsl with the vscode wsl extension.
My question is why would I do this over just using vscode on Windows.
Might sound like a silly question and I hear people saying I can now develop on Linux where my company is is windows, I just don't understand what the benefits are
It all depends on what you are developing, if its C# with the target operating system being windows or azure there is little benefit.
Personally I work in nodejs, our target deployment OS is centos running in AWS-EC2, so it makes total sense. There is a lot of tooling that runs better in a linux environment than in a dos/powershell environment. Also when testing we are running the code in an environment that is close to our target env which reduces the chances of unforeseen issues further.
Does this make sense? what are you developing day to day and what is your target environment?
I'm running Minecraft on a headless Linux server with OpenJDK. I've added a bunch too many mods and its lagging (even on my local network) without using too much CPU or memory (e.g. its lagging, but its still got resources it can use). So I'm pretty sure its a mod fault.
To save the hassle of removing/adding mods one by one to see whats causing the error, my research led me to VisualVM where you can profile the java application and see which entities are doing what and with what resources. With any luck it should point out the mod consuming the most resources, and the most ticks.
Given its a headless server, and VisualVM is a window/GUI application, I've successfully managed to get it running and passing the GUI back to my Windows client using X over SSH.
Trouble is now, that its telling me that I need to use JDK and not JRE. Which is fair enough. Except OpenJDK has JDK in its name, rendering all googling futile. I cannot for the life of me, find if JDK is included in OpenJDK, what its named, and where it may be located. The other problem is, most of the troubleshooting guides I find are for Windows, and dont help me find the JDK on linux.
As some background information, I'm running Debian, and I know OpenJDK's JRE is installed here: /usr/lib/jvm/java-7-openjdk-amd64/jre
Can someone tell me please, if JDK is in OpenJDK, or I need to install it as well? If I do need to install it, is there an OpenJDK equivelant for JDK? If its already included, can someone provide some tips on locating it, so I can point VisualVM at it instead of the JRE?
The OpenJDK has a JDK, but there is also a cut down version which is just the JRE. I would use locate javac and if it can't find it, you need to install the JDK.
I've been using VMWare Player for ages now for both Windows development on my Linux box and (more importantly) automated testing of Windows applications.
Basically what I do is to:
have my development VM running and I build my code and automatically transfer the install package to Linux.
when this shows up at Linux, automatically copy a "known-state", snapshot VM to my test work area (I say snapshot but it's really just a backup copy of the whole directory, not a real VMWare snapshot).
also automatically start the VM in the work area once it's copied.
the VM has a single never-changing startup script which pulls a real startup script from Linux and runs it.
that startup script is responsible for getting down the install package and doing a silent install.
it then runs a test suite and uploads results back to Linux where I have automated scripts which check them.
So, it's basically a one-button test process.
Now I notice more and more people seem to be using VirtualBox.
First off, I'd like to confirm that it can also do a similar thing, primarily being able to backup and restore whole VMs and having shared folders between VirtualBox and Linux.
Secondly, and this is the crux: I'd like to know if that has any concrete advantages over VMWare Player, especially for the automated testing jobs.
I switched to VirtualBox because of one concrete advantage, I wasn't able to setup the network as I wanted to in player. I don't remember if it was bridging or port-forward or whatever that didn't work, but something didn't work the way I wanted it to with the network-setup (cause I needed the pay-version for that) and thus I switched. Personally I've found that both have good and bad sides, but I still use virtualbox cause of that network-thing.
Looking for some help with getting xdebug to behave with my setup. My goal is to be able to debug Joomla code.
First let me preface saying that about a year ago I was able to get a version xdebug to work with Eclipse PDT 2.1 with xampp under Vista 32bit. However, now I'm on a new machine, and I wanted to get everything working with the latest versions. I did so by following through this walk-through. Now, trying to do the same thing I can't get it to work.
First, as per the walk-through, I downloaded php_xdebug-2.0.0-5.2.2.dll. Quickly realized that I needed an xdebug for php 5.3. So, I found the xdebugs Tailored Installation Instructions and followed that. My php.ini section looks as thus:
[XDebug]
;; Only Zend OR (!) XDebug
zend_extension = "D:\xampp\php\ext\php_xdebug-2.1.0-5.3-vc6.dll"
xdebug.remote_enable=true
xdebug.remote_host=localhost
xdebug.remote_port=10000
xdebug.remote_handler=dbgp
xdebug.profiler_enable=1
xdebug.profiler_output_dir="D:\xampp\tmp"
So this got the xdebug to actually show up in the phpinfo(). But, in Eclipse when I Debug As Php Webpage, it at first appears to connect, however if I step to the next line of code the debugger just sits there saying it is stepping, indefinitely. Sometimes apache will crash. I tried ports 9000, and 10000 with no avail.
What I did find out is, if I use the the php_xdebug.dll that comes with XAMPP 1.7.3, I actually can connect and step without any issues, EXCEPT, that version of xdebug apparently has a major bug in it that causes all my variables to be listed as 'Uninitialized'. So it is basically useless, however, it does give some hope that I have some of this stuff set up correctly.
So, my current setup thus: Win7 32bit, XAMPP 1.7.3 (PHP 5.3.1, Apache 2.2.14), Eclipse PDT 2.2
I have very limited experience with basically all the tools here so I'm kinda at a loss of what to do. Any help would be greatly appreciated. I searched some of the other posts here with similar issue but most of them appear to be for older versions of these components.
your report is somewhat confusing. As far as I understand you, your setup works as soon as you replace the XDebug-dll. Then your (primary) problem cannot be related to your settings, as far as you also adjusted zend_extension, of course.
Though xdebug.remote_port=10000 seems odd. Std is 9000. If you use 9000, the you have to tell Eclipse in Window/Preferences/PHP/Debug/Debuggers to also listen to that port for XDebug.

What's the best setup for developing Linux apps from a Windows workstation? Right now I'm connected via SSH to our Linux development server and am using Eclipse, forwarded over SSH via PuTTY, to the public domain version of Xming running on my Windows workstation. It works, but it's not great; Eclipse's response times are far from snappy (noticeably worse than Eclipse running natively on my much slower Windows workstation), I can't resize some dialog boxes, and I haven't figured out a good way to reconfigure my fonts.
Is there a better setup available?
Edit: This is for C/C++ development.
Options for Linux on Windows:
Tools Only
Given you're using Eclipse I'm going to assume you want a full IDE, but if you can get by with just the GNU/Linux tools, there are a few choices.
cygwin gives you a bash shell with lots of tools, including an X11 server. This has been around awhile and is mature.
msys is a smaller, lightweight alternative to cygwin.
GNU utilities for Win32 is another lightweight alternative. These are native versions of the tools, as opposed to cygwin which requires a cygwin DLL to fake out its tools into thinking they are running on Linux.
Linux in a Windows Process
There are several packages that will run Linux as a Windows process, without simulating an entire PC as virtualization does. They use Cooperative Linux, a.k.a. coLinux, which is limited to 32-bit systems. These don't have the overhead of virtualizing, and they start up faster since you're not booting a virtual PC. This is a little more on the experimental side and may not be as stable as some of the virtualization options.
Portable Ubuntu
andLinux
Virtualization
Virtualization software lets you boot up another OS in a virtual PC, one that shares hardware with the host OS. This is pretty tried-and-true. There are nice options here for taking snapshots of your Virtual PC in a particular state, suspend/resume a virtual PC, etc. It's nice to be able to experiment with a virtual PC, add a few packages, then revert to a previous snapshot and "start clean".
VMWare
VirtualBox
VirtualPC
In my case...
Sounds like your environment has different performance characteristics, but here's my situation: I started out with Eclipse on my Windows laptop (doing Rails development), found this sluggish, and switched to using putty to ssh into a fast Linux box. I do my editing via an emacs running on the Linux server, displayed on Windows using Xming. Or I use native emacs on Windows, editing the files shared via NFS. The latter is slower in my environment due to sluggish saves.
When working from home, I ditch X because it is too slow with remote clients, and just run emacs -nw within a putty window. I then use GNU screen so that I have multiple "windows", and so that I can easily resume where I left off if my network connection flakes out.
The best approach that I've found is to:
keep your code portable
develop natively on your desktop
verify any OS dependencies (minimize these as much as possible)
deploy to your target regularly, test & debug there
I know that this isn't a direct answer, but using an IDE for development through X is painful with most of the free tools. The only way that I've been productive doing work this way was when I was running a UNIX-like on my desktop so X was native. If you are going to use this approach, try a commercial X solution on the desktop.
Other than that, consider ditching the IDE and doing your development and debugging via SSH, a terminal editor (e.g., vi, pico, ee, emacs), make/ant, and gdb.
The best approach for you is going to be driven by your programming language and the type of application you're developing. If you are doing GUI applications, then using X might be the only approach that is acceptable. If you are doing back-office/daemon development, then the SSH and terminal approach will probably work though you probably want to get really comfortable with either vi or emacs.
EDIT: just noticed that you are doing C/C++ development. Consider using a cross platform framework if you aren't already. Using something like Qt, APR, ACE, or Poco should make it possible to natively develop under Windows with a deploy/debug step to your Linux environment.
For development I usually use a Linux virtual machine on my Windows box. It will probably send Linux users running to the bathroom to wash their hands, but I do all of my development in Visual Studio, and I have a custom Visual Studio plugin that invokes G++ through the virtual machine and pipes the output into the VS output window. With a quick change of a Combo box I can build and test for Windows or Linux.
An easy to setup option would be to run Eclipse natively in windows but deploy the code via a Samba share on the Linux machine (which you can mount as another drive) (or SSH/SCP if SMB is not an option) and then run it there via SSH console.
Another easy to setup option is to simply develop on Linux via freenx or a similar tool instead of a full blown X session, check this answer: https://serverfault.com/questions/11367/remote-desktopping-from-windows-to-linux/11372#11372
The other options (Virtualization, Linux running inside windows, Cygwin) are indeed valid but have their drawbacks, like being more machine demanding, harder to setup, or not equivalent enough to the actual linux environment, but may very well be worth your while if you have the machine and the scenario justifies their use.
Doing everything on the Linux side will always have some drawbacks
if your machine is Windows.
I personally have a Linux box where everybody else has Windows and
do Windows dev inside a VM, but it has costed me a lot of RAM and some network setup pains.
I find coLinux tremendously helpful when developing on Windows for Linux, it's basically a linux system running in parallel to your Windows OS (i.e. as a service) and can be configured to simply show up on your LAN, basically like a virtual machine does. Also, it's much more full featured than CygWin, and its performance is really remarkable - I can easily run non-trivial stuff under coLinux, and still run simulators at 90+ fps.
Also, coLinux can be easily set up to run X11 and window managers like gnome/KDE, so that you can for example use something like vnc to access your linux desktop.
Cooperative Linux is the first working free and open source method for optimally running Linux on Microsoft Windows natively. More generally, Cooperative Linux (short-named coLinux) is a port of the Linux kernel that allows it to run cooperatively alongside another operating system on a single machine
. For instance, it allows one to freely run Linux on Windows 2000/XP, without using a commercial PC virtualization software
such as VMware, in a way which is much more optimal than using any general purpose PC virtualization software.

There are multiple solutions, I'd recommend No. 1
A VM (Virtual Machine) running a flavor of linux as a guest operating system inside Windows. Start with VirtualBox which is free.
To make managing it easier you can use a tool like Vagrant. Vagrant is a tool for building and managing virtual machine environments in a single workflow. With an easy-to-use workflow and focus on automation, Vagrant lowers development environment setup time, increases production parity. So you code in your Windows PC and compile/run the application on a Linux system using Vagrant. Vagrant is free! Similar tool: Docker can be used too. For this setup you can use any IDE, I'd recommend VSCode its quite handy for C/C++ with intellisense but Eclipse should work too.
Web based tool like Nitrous.io which is discontinued, but you can host your own open-source version of the Nitrous IDE called Nitrous Solo which lets you host your own instance of the Nitrous IDE on your preferred cloud provider.
Windows 10 provides provides Windows Subsystem for Linux, try using that to compile and run your project. This requires a 64-bit version of Windows 10 Anniversary Update or later (build 1607+).
Cygwin / MinGW are popular bash tools for Windows, they might be able to compile and/or run your application.
Cygwin might be helpful.
I've done what you want to do for exactly the same reason: full control over the output (you're having font issues with your current solution) and much slower Windows machine than the remote Linux development box.
Most answers are bogus: having a "Linux development environment" is not just "having an IDE". It's about having the whole Un*x power at your fingertips.
Is it a local or remote Linux server? bandwith issues? Because on a LAN, even an old 100 MBit/s LAN, FreeNX flies. How's the load on that Linux server?
Setup the free FreeNX on the Linux system, install the free FreeNX client on the Windows machine and bingo, you've got your Linux development environment at your fingertips.
FreeNX is much more efficient than VNC, it's night day (VNC is actually pretty bad perfs wise, even compare to Windows's Remote Desktop... But FreeNX flies).
Regarding speed, a long time ago, I set up my main Linux workstation (it was a Pentium 4 / 2GB of memory back in the days) on which I was developing full-time using IntelliJ IDEA (another IDE), to serve a full X session (complete with a window manager etc.) that another developer was displaying remotely to... run another IntelliJ instance (and access all the Un*x niceties). It was on a LAN 100 Mbit/s and it was as if the app was local for the other developer.
Anyway, on today's hardware I cannot imagine how this could not work: I now have here a Core 2 Duo / 4GB of ram as my main desktop and a Gigabit LAN.
Such a setup was working perfectly 4 years ago, it would work perfectly today.
Now if you tell me you have bandwith issues or that the Linux machine you've got your account on is under heavy load or that it's not on the LAN, then things may be different...
How the younger developers who want a powerful Un*x system do it at the company I'm consulting for nowadays (that only has Windows desktops)? Most of them bring their shiny MacBook Pro and use that to develop ;)
I'm using xming as well and suffer from the same problems with Eclipse. Apparently, neither switching to cygwin makes it fast enough. Eventually I switched to developing in vim via xming. It doesn't take as much time as I feared to get used to all the key combinations, and the performance is absolutely smooth. Actually, now sometimes I use vim even when working natively.
Either a Virtual Machine with a Linux-based dev environment, or a local copy of some toolchain-agnostic IDE (e.g. Notepad++, with testing done via MinGW or CygWin as far as you can), or just write in Notepad++ and keep uploading to your dev machine and testing there, which is what I do.
You might try other X servers on Windows such as xwin32 and hummingbird. Note that these are commercial implementations.
Another solution is to install a VM server on your Windows box and install Linux on the VM. Options include VMware (non-free) and Microsoft Virtual PC (free download). VMware is much nicer than VirtualPC (64-bit support, more incentive to support Linux client OSes, etc.).
EDIT: In the last 13 years since this post was originally made, Cygwin/X (and Xming) has gotten a lot better. It's worth trying again. I now use it for my everyday work again.
You could take a look at setting up a svn server on the linux box and then using something like TeamCity todo a build on commit. You could write your code locally and do a commit when you want it to be compiled.
I don't know if there's a more modern route, but the standard way in my time was to run X Windows in Microsoft Windows, that way you can run any number of applications on your Ubuntu machine and control them and display them in Microsoft Windows
Check Check out.
You could try using any of the linux distros for windows, even windows-store have ubuntu, SUSE etc for windows and this could help reduce your coding efforts. This linux distros contain linux shell, kernel etc so you won't be needing linux system everytime debugging or testing your code.
You could also use Visual Studio Code which is far better and fast compared to eclipse and is even supported in linux and mac.
Check this for ubuntu distro on windows store.
Linux distros can also be downloaded from other sources but microsoft urges to use the one from Windows-Store.
Use Linux! I usually have the other problem: developing win under linux.
There is no reason for not doing so: I have win running on a virtual box now almost all the time.
Linux comes with a lot of development tools.
The problem is:
is it a graphical interface?
If no you will have no problems as soon as your code STD/portable.
(X allows you simple stuff too but for an nice application today you need a bit more.)
If Yes then you will have a lot of problems when you actually port the code
on the running platform.
Is it supposed to be portable/exchangeable between linux and windows?
if not, just develop on the native OS. Way less pain. You have Eclipse for both
platforms. Even if you think to port the code on a later stage,
just do the work for one first.
I developed a couple of graphical application under linux which are actually right now
used only under windows. My recipe is: GTK/GNOME. I made it running with cygwin and mingw.
But I guess that Qt has the same usable environment too.
My code went on win with no changes!
[ok.. a couple of touching on file paths... but was a bug..]
There is no way to develop under win and hope to be running on linux unless you are sure
not to use any win libs. That is: in a graphical application almost no chance. Or a lot of
checking... Or you will not be using any win facility. Forget Visual Studio.
Check indeed wine and the winehq pages.
Unless the problem is another, like: using team sharing facilities, or svn or whatever.
Which is not a code development problem but a bit more on the organizational side.
Bottom line:
It is way easier to port a free code on win then a proprietary code on the free market.
