# Cross compiling

General guide for cross compiling.

## Debian ARM64

A painless guide for cross compilation (or to test NCE) from a x86_64 system without polluting your main.

- Install QEMU: `sudo pkg install qemu`
- Download Debian 13: `wget https://cdimage.debian.org/debian-cd/current/arm64/iso-cd/debian-13.0.0-arm64-netinst.iso`
- Create a system disk: `qemu-img create -f qcow2 debian-13-arm64-ci.qcow2 30G`
- Run the VM: `qemu-system-aarch64 -M virt -m 2G -cpu max -bios /usr/local/share/qemu/edk2-aarch64-code.fd -drive if=none,file=debian-13.0.0-arm64-netinst.iso,format=raw,id=cdrom -device scsi-cd,drive=cdrom -drive if=none,file=debian-13-arm64-ci.qcow2,id=hd0,format=qcow2 -device virtio-blk-device,drive=hd0 -device virtio-gpu-pci -device usb-ehci -device usb-kbd -device intel-hda -device hda-output -nic user,model=virtio-net-pci`
