Rasberry PI 4: gcc: error: unrecognized command line option ‘-mno-red-zone’; did you mean ‘-fno-regmove’?

[Gys]

I have a Raspberry Pi 4 with 4Gb memory and tried the 'Getting Started' code from the readme:

wget https://justine.lol/cosmopolitan/cosmopolitan-amalgamation-0.2.zip
unzip cosmopolitan-amalgamation-0.2.zip
printf 'main() { printf("hello world\\n"); }\n' >hello.c
gcc -g -O -static -nostdlib -nostdinc -fno-pie -no-pie -mno-red-zone \
  -o hello.com.dbg hello.c -fuse-ld=bfd -Wl,-T,ape.lds \
  -include cosmopolitan.h crt.o ape.o cosmopolitan.a

The gcc line gives the error gcc: error: unrecognized command line option ‘-mno-red-zone’; did you mean ‘-fno-regmove’?

The gcc -v output:

Any ideas?

AFAIK, this only works on x86 platforms, raspbery pie is ARM.

Ok, I did not realize the example is x86 only.

@Gys Apparently Cosmopolitan binaries can even run on ARM if you have qemu installed! See https://github.com/jart/cosmopolitan/issues/73
