<p>The OpenJDK build cannot handle paths with spaces in them, and on
Windows, where the default installation directories of things like
Visual Studio and the SDK have spaces in the directory names, we
rely on short paths to work around this. If you installed Visual
Studio in the default location, you should not need to point to a
tools dir, and doing so won't help if the paths can't be expressed
without spaces in them. It's annoying that Windows seems to have
turned off short path generation by default in later versions.</p>
<p>You could try enabling 8dot3name on the whole volume (C:) using
fsutil [1], but you probably need to reinstall Visual Studio after
that to get the short path names generated for all the directories
in the installation.<br>

<div>Usually Microsoft Visual Studio c compiler (as
installed by Visual Studio installer) already has
short names set. It seems the short name has to be 8
characters in length and you can't set it when some
process is running in that directory. You can check
the short path in Windows cmd's "dir /x" command. And
try configure without --with-toolchain-version and
--with-tools-dir and only set these flags if it fails
without those flags: you declare version is 22 but you
point to MSVC 2019's directory, and you should point
to the bin directory within the VC directory.</div>

<p>Hello Anil,</p>
<p>Building in a VM on a laptop should
be doable, but given how resource
intensive the JDK build is, you
could run into problems like you
describe. You are most likely to get
the best build performance running
natively on the machine and OS you
have, so my recommendation is to
build for Windows in your case. If
you still prefer to build for Linux,
I think the best option is to use
WSL. See doc/building.md for
instructions on how to build for
Linux in WSL. To build for Windows,
I recommend installing Cygwin as the
most straightforward and well tested
option for a POSIX support layer on
Windows. Once installed, you won't
need to run any Windows commands as
Cygwin emulates a Linux/Unix
environment. Again see
doc/building.md for instructions on
how to install a build environment
on Windows.</p>
