I have never tried to compile this on an ARM platform. I am happy that it actually works.

Error: Cannot control floating point exceptions and rounding mode on this platform

This means that it doesn't know how to control floating point exceptions on the ARM platform. You can ignore this as long as you are not working with floating point exceptions.

Error 320: Unresolved external symbol _print_string in module calculator.ob

You are missing the library libc_light.li or libc.li

FILE=calculator
./forw -ass $FILE.as
./forw -link $FILE.ex $FILE.ob libc.li libc_light.li math.li
./forw -emu $FILE.ex -list=out.txt

🤩

So it works
