Hello,
Glad to hear you got Cygwin in order!
The officially supported toolchain for jdk/jdk (current mainline for JDK
11) is VS 2017. We recently upgraded from 2013. Amber seems to be pretty
much up to date with that from looking at the repo changes. You can
check at the top of toolchain_windows.m4 for the list of VS versions.
The order of that list shows our preference. I do not think 2010 works
well since we upgraded from that to 2013 a long time ago in JDK 9. I do
believe 2015 should work, but last I tried, I needed to add
--disable-warnings-as-errors to get through. For 2017, you only need the
"BuildTools" edition if you want to minimize the install. If you want
the Visual Studio IDE, then community edition works just as well.
If you are running Windows 10, you can also try installing the Windows
Subsystem for Linux. In my experience, OpenJDK builds pretty much out of
the box in Ubuntu under WSL as long as you provide a bootjdk of the
correct version (for Linux). You get a Linux binary that works in WSL
(or native Linux).

Hello guys,
I tried the rebaseall and it worked. Tbh, I hadn't really looked into
cygwin that much since I wanted to avoid having PATH conflicts between
3 different versions of tools (one windows, one msys, and one cygwin).
I should have done that right away though since it was really easy to
get working, and also runs 'configure' about 10x faster (although
having to use the installer to install packages is somewhat annoying).
I think I'll just shelf msys2 for now, since it's not that important
to me, and building openjdk is more of a hobby thing any ways. Btw,
the patch that you linked, Magnus, is private, i.e. it returns a '403
- Forbidden'.
I have thought about using virtualbox to emulate linux to build in
there, but it requires me to enable virtualization in my BIOS and
doing that makes my machine boot up significantly slower. Fast startup
is more important to me (like I said, building ojdk is more of a hobby
thing). I also have a decade old PC that runs Ubuntu, but I'm sharing
the monitor with someone else, so I can't always use it. That's why
I've settled on getting the build to work natively.
Any ways, I ran configure and ended up with the following (I'm trying
to build the amber repo btw):
```

```
I tried with VS 2015 community, but it was warning about not being
supported? I guess that change hasn't propagated to the amber repo
yet, so I'm using VS 2012 express. (I have also tried installing VS
2010 express, which I believe is recommended, but it doesn't seem to
include a compiler? There's a service pack which I think includes the
compiler, but it requires windows SDK 7.1 which 'encountered some
problems during installation' *sigh*).
Then running `make clean images` I had an error about inttypes.h
missing, which I downloaded to fix that error, but now it's also
complaining about other stuff like:
```
j:\cygwin64\home\Jorn\cygwin-projects\amber\test\fmw\gtest\include\gtest/gtest-printers.h(550)
: error C2977: 'std::tuple' : too many template arguments
j:\progra~2\micros~3.0\vc\include\utility(73) : see
declaration of 'std::tuple'
```
And many more such errors after that. So I suppose VS 2012 express
isn't supported either (even though it doesn't give a warning)? Maybe
I'm missing something, I only installed VS 2012 express from here:
https://www.visualstudio.com/vs/older-downloads/ . Or does the amber
repo require some tricks to get working?
Close yet so far. Thanks,

I second the advice to get cygwin up and running. Cygwin is the
canonical way to build on windows. Unless you have really pressing
reasons to use something else, I would use what (almost) everyone else
uses.
I have my windows build env up and running on a fresh windows machine
usually in ~30 minutes. It should not be rocket science. I use both
windows 7 and 10 for my work.
Some more points, in additions to what the others wrote:
- 64bit seems to be the standard: 64bit windows, building 64bit ojdk
with a 64bit cygwin. Other configurations may work but are less well
tested. Just something to keep in mind.
- If you do not trust your windows machine and suspect its software
stack may be messed up somehow, there is always the option of
installing a fresh copy of windows in a virtual machine, e.g.
VirtualBox, and install the tool chain from scratch (cygwin + vistual
studio).
Best Regards & good luck,
Thomas

Hi Jorn,
As you probably have understood by now, porting OpenJDK to msys2 is
not just
a simple quick fix. If all you want is to build OpenJDK on your Windows
computer, you are probably better off by trying to fix your Cygwin
installation. From your description, it sounds like you'll need to
rebase
it: http://cygwin.wikia.com/wiki/Rebaseall.
If you want to pursue the msys2 path (and I'd appreciate it; it
would be
good to get OpenJDK working on msys again), I suggest you start by
looking
at the work that had been done before (but never merged into
mainline). See
this conversation:
http://mail.openjdk.java.net/pipermail/build-dev/2017-October/019897.html
Peter Budai got the msys part working, but he had more ambitious
goals of
getting gcc to build on Windows, which is magnitudes more work, so
his patch
was never finished. Nevertheless, he published a patch in [1] which got
stripped by the mailing list. I've put it up here:
http://cr.openjdk.java.net/~ihse/msys2/jdk9-mingw.patch
It is for jdk9 so it's not possibly to apply out of the box, but you
can
probably see what's been done and trying to reimplement it. I think the
"magic" part is setting MSYS2_ARG_CONV_EXCL= (the empty string), which
disables msys2 path mangling.
Good luck!
