Is anyone using msys to build OpenJDK? (original) (raw)

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

From the source history, it appears that with JDK9 we dropped support for msys:

http://hg.openjdk.java.net/jdk/jdk/rev/2a2e56f4c03b This was committed about 1.5 years ago - are you suggesting that perhaps we added support for msys2 later on (perhaps unofficial or undocumented)?

If anyone is currently using msys to build OpenJDK, I'm curious to know what version so I can replicate that environment. As we are trying to add WSL support, we are touching all sorts of places in configure, and there is a big risk that we break the existing msys support. I would like to be able to setup an environment so I can at least do basic verification of such changes. I know we initially set this up for msys, but later I tried msys2, which seemed a lot more modern and easy to use. I do remember there were several options on how to setup it up exactly though. /Erik
