Running x86 programs with qemu #171

Closed rulet closed 4 years ago

Hello. It's actually not an issue. I have a question if you can help to run x86 programs with qemu on your system on raspberry pi 3 v.B? The purpose is to run simple windows application with wine. Can you provide some instructions for that?

That's really outside the scope of this project... That said, you need to emerge qemu with QEMU_USER_TARGETS="x86_64" (and whatever other targets you want). You can then set up a chroot with wine in it and run that, similar to how qemu and a chroot can be used to compile arm programs from an x86_64 host.

All that said, aarch64 (64bit arm) is a fairly RISC instruction set, which can be easily translated to the CISC instruction set of x86_64. The inverse is not true. Do not expect decent performance going this route (i386 dos programs work reasonably inside dosbox, late 90s programs might work passably).

Thanks @perkinslr. Closing.
