rtools40 on Mac M1 running Windows 10 on ARM in Parallels Desktop

[thioulouse]

Hi, I am trying to install rtools40 on a Mac M1 running Windows 10 on ARM in Parallels Desktop 16.5.0. The reason why I am doing this is that I would like to be able to build binaries of my packages on the same machine. It is already possible to build R and binary packages (both x86_64 and arm64) on the Apple M1 Macs under macOS, so it would be nice to be able to build the binaries under Windows 10 on ARM. Is there any possibility to do it ?

The problem is that when I try to use the 64-bit rtools40 installer, it says that "The 64-bit installer cannot be used on 32-bit Windows". And when I try to use the 32-bit rtools40 installer, it says that "The 32-bit installer cannot be used on 64-bit Windows".

Windows Settings reports System type as "64-bit operating system, ARM-based processor".

R itself and the Rgui are running fine in 32-bit mode, but the 64-bit version does not run...

I have never tried arm on Windows, but I would not expect regular x64 binaries to just work. Are you using the x64 emulation mode as described in https://blogs.windows.com/windows-insider/2020/12/10/introducing-x64-emulation-in-preview-for-windows-10-on-arm-pcs-to-the-windows-insider-program/ ?

I can modify the installer to allow arm64, but I am not sure if the compilers will actually run: https://github.com/r-windows/rtools-installer/commit/6aa5da09c97d09b76e8101749f2fb0bd25009b93

Could you try to install the latest rtools40 installer from: https://ftp.opencpu.org/rtools/installer/rtools40-x86_64.exe

[thioulouse]

Yes, using x64 emulation mode or R would not run. But only the 32bits (i386) version of R runs, not the 64 bits (x64).

And this latest rtools40 installer works too ! Thanks ! I'll try to compile something now...

[thioulouse]

Compilers run fine (for both arch) but install only works in i386 arch (not for x64), which is coherent with R behaviour in this setup. Also, there are some Cygwin warnings but I was able to load and run the compiled package.
