Building under windows

[Ian McCallion]

Does anyone build octave under windows?

If so is there a beginners guide somewhere that I can follow to get me started?

The windows version of octave is cross-compiled from linux, i.e. built
on a Linux computer. I think you will find it challenging to do a native
build to say the least. The standard way to build the windows version is
to use mxe-octave, info here:

https://wiki.octave.org/Windows_Installer

You might be able to do this on Windows 10 if you install the linux
subsystem for Linux and and build it in that environment. Never tried
this, and have no idea if it works.

FYI  the Windows subsystem for Linux details:

https://docs.microsoft.com/en-us/windows/wsl/install-win10

Would be great if this worked and we could document it.

Some months ago, I installed the "Ubuntu App" for the Windows subsystem for
Linux and successfully compiled Octave with it.
Installing the App is as easy as hitting the "Install" button in the Windows
Store.
The instructions for compiling Octave are the same as for a "real" Ubuntu.
With an installed X-Server for Windows (I used VcXsrv), it even runs with
the GUI. I thought that plotting was possible too. But testing that now, it
crashes the X-Server.
A real downside is that all file operations seem to be incredibly slow.
Thus, compilation took quite some time. This might be a local system thing
(maybe antivirus?).
To get a true native Windows application, cross-compiling with MXE Octave is
still necessary. I never tried that with the "Ubuntu App" however.

Personally, I went back to running Ubuntu in a "real" VM because that seemed
to perform much faster.

It would be interesting to hear other's experience.

I have tried to build octave 4.4.1 on wsl using using ubuntu 18.04.  Slow build on wsl relys on slow fork on wsl.  That is similar to slow fork  on cygwin. fork in wsl is faster than that on  cygwin.

I tried this before but I abandon to do it because it is very very slow.
It is better to prepare real linux PC to purchase corei5 PC from net auction.
(I do it)

For me it does not crash but no plot appear with qt graphics_toolkit.|
For fltk, plot appear immediately.
