Oh dear, I always get that the wrong way around, you need :0, not 0:.
It's probably something else anyway, it depends how the network stacks
on the linux and win subsystems are set up.

export DISPLAY=:0

Your view makes perfect sense, no worry! :-)
It would be good if this new Bash in Windows helped Windows
contributor build, hence code for GIMP, since the project is seriously
lacking from developers on this platform.

Now what I don't understand is that you are trying to build *on*
Windows *for* Windows, yet you are writing about cross-building. That
should be a native build instead, not a cross-build… unless I really
misunderstand what this bash shell on Windows is, but I don't think
that's supposed to be an emulator, right?!
So if I understand you well, you don't want to cross-build. :-)

Now to know exactly how we can help you though, it is necessary that
you explain exactly what you already did, just as Michael Schumacher
proposed.
The fact is that you actually won't find what you are looking for
(someone who already did it and could give you hints) since — as I
said — we are lacking dedicated Windows developer. You are maybe the
first to try building on this new Windows-Bash shell, and in that
respect, you are an explorer of this new Windows feature. In the end,
if you manage to do it, you will likely be the one able to explain
others. :-)

Now we can still help you with generic and theoretical help on what we
know about building GIMP in general, but not specific help.
But feel free to ask and tell us on your advances on the matter. We
are very interested on the topic. Also you can always ask me stuff
personally. I am the GIMP newcomers mentor, so reaching out to Windows
developers in one of my hope to improve GIMP.
Thanks!

Re: [Gimp-developer] Windows 10 and Bash on Ubuntu

[jcupitt]

It sounds like you've managed it! As Partha says, you can't run graphical
Linux programs directly from win10, you need to install an X11 server on
the Windows side.

>From the win desktop, install an X11 server, there are loads of free ones,
and start it running. Check the instructions on how to set the display
variable.

Back in the Linux shell, enter something like

export DISPLAY=0:

Then try running your gimp build. People have got the entire KDE desktop
working this way, so there's a good chance it'll just work.

You've made a Linux build of gimp so it won't be directly useful to windows
users, or easy to package or distribute. You'll need to look into the mingw
cross-compiler if you want to make a native windows binary from Linux.

Re: [Gimp-developer] Windows 10 and Bash on Ubuntu

[Petteri Soininen]

Hi

Not gaining personally anything, but maybe making development builds 
more accessible to those who come from MS Windows backgrounds.


Now they have to setup a Msys2 environment and do builds with that, 
which isn't as easy as it sounds with instructions that are partly 
outdated, but if Win10 has an Ubuntu shell, that probably is quite same 
for everyone who uses it, so why not try to build GIMP for Windows with 
that? GIMP isn't supposed to be an elitist Linux application, but a 
serious cross platform tool for everyone. Or so I have thought this far.

Well, GIMP is a graphical application and X11 are not officially 
supported on WSL. So, first you'll need to install X11 and then set 
the display appropriately. If you are familiar with Linux this should 
not be a problem. I think the command is something like export display.


If you simply plan to cross build, I am not sure what you are gaining 
with WSL.


Hope that helps.

I'd probably try cross build since after 'sudo apt-get install gimp' and 
trying to run it, it fails on 'cannot open display' so I think that 
indicates the shell cannot run it under windows and gimp needs to be 
built as a cross build. But as said, I'm just a beginner.  :)

Hi Petteri,

this is the point where you should explain what you did in

to reproduce what you did, without knowing what you did.
