At the moment, the only open source toolchain supporting windows-arm64
is llvm-mingw (https://github.com/mstorsjo/llvm-mingw).
There is some progress on gcc, but it is not yet fully upstream.
MSYS2 uses llvm-mingw for windows-arm64 environment.
On my side, I used a windows-arm64 machine with MSYS2 native environment.
It would be handy to cross compile, and the problem is not really QEMU
itself, but to cross compile all the dependencies.
For x86_64, we use fedora, which provides convenient precompiled mingw
packages for dependencies.
It's definitely not impossible to do the same for windows-arm64, but it
just takes much more effort.
Is there an MSYS2 or other distributor that provides windows-aarch64
builds of the glib and other library dependencies?
MSYS2 does, but it's complicated to download packages by hand if it's
your idea. Better to cross compile it.
I could run a QEMU cross compile on Debian with the llvm toolchain and
msys2 clangarm64 packages installed with pacman. The resulting installer
is here:
https://qemu.weilnetz.de/aarch64/
The only tools which was missing and which I had to build before running
the QEMU build is aarch64-w64-mingw32-windmc.
It looks like the NSIS installer is i386 code, so I don't know whether
it can be used on Windows for aarch64.
I also have no suitable Windows host for testing the binaries, so no
test was done.
