# Troubleshooting
## `binfmt_misc`
Linux is able execute binaries from other architectures, meaning that it should be
possible to make use of `pi-gen` on an x86_64 system, even though it will be running
ARM binaries. This requires support from the [`binfmt_misc`](https://en.wikipedia.org/wiki/Binfmt_misc)
kernel module.
You may see the following error:
```
update-binfmts: warning: Couldn't load the binfmt_misc module.
```
To resolve this, ensure that the following files are available (install them if necessary):
```
/lib/modules/$(uname -r)/kernel/fs/binfmt_misc.ko
/usr/bin/qemu-arm-static
```
You may also need to load the module by hand - run `modprobe binfmt_misc`.
