I might not have Amiberry — an optimized Amiga emulator for Raspberry Pi — running quite yet, but the build instructions at midwan/amiberry are a bit lacking. If you want to compile it under Raspbian Stretch, you’ll need the following packages:
sudo apt install libsdl2-dev libxml2-dev libxml2-utils libsdl2-ttf-dev libsdl2-image-dev
This will at least allow you to get it to build correctly with:
make -j2 PLATFORM=rpi3-sdl2-dispmanx
More later when/if I get it working.
