#### for PI4
#### for Raspberry Pi 3

Warning, you need a 64bit OS:

If building on the Pi, you will also need a large swap (2 GB+)
and reduce GPU memory to a minimum (e.g. 16 MB) using `raspi-config`
(and reboot) before starting the build:

You can use e.g. '`make -j4`' to speed up the build, but on a Pi 3 with 1GB memory you will likely
run out of memory at some point and need to run the build again.
Still, this can be faster if your build is attended.

```
git clone https://github.com/ptitSeb/box64
cd box64
mkdir build; cd build; cmake .. -DRPI3ARM64=1 -DCMAKE_BUILD_TYPE=RelWithDebInfo
make
# or e.g. make -j4
sudo make install
```
