Is anyone using msys to build OpenJDK?

[Volker Simonis]

It is a long time ago (~2012) that I added and fixed the MinGW/Msys build
[1] on Windows. We at SAP used it productively for some years because at
that time Cygwin was terrible slow, buggy, had no 64-bit version, wasn’t
really maintained very well, etc...

But things have changed to the opposite since then and we‘ve switched to
Cygwin at least 3 years ago (can‘t find the exact date now).

As far as I know, there haven‘t been any serious users of the MinGW/Msys
build since then. At that time MinGW/Msys had some serious problems which
made it impossible to do parallel builds. Not sure if that has been fixed
by now?

I personally always liked MinGW/Msys compared to Cygwin because of the (at
least in my eyes) more intuitive way of handling Unix/Windows paths it’s
simplicity and speed. I’m not sure however if it is currently actively
supported, and if the old problems have been fixed.

So to finally answer your question :) I don’t think anybody is currently
using the MinGW/Msys build and I doubt that it will work without bigger
adaptions and fixes.

Regards,
Volker
