I am tring to install XV6 on my MacOS. These are the steps I followed:
- Downloaded xv6 from https://github.com/mit-pdos/xv6-public
- Installed qemu using
brew install qemu - Installed i386-elf toolchain from https://github.com/nativeos/homebrew-i386-elf-toolchain. Used these commands:
brew tap nativeos/i386-elf-toolchain
brew install nativeos/i386-elf-toolchain/i386-elf-binutils
brew install nativeos/i386-elf-toolchain/i386-elf-gcc
After cloning the xv6-public repo, I changed the Makefile to the one given in https://github.com/ashr123/XV6-MacOS-Makefile/tree/master
Now I ran make qemu clean from the xv6-public directory.
I get this error:
i386-elf-gcc -fno-pic -std=gnu17 -static -fno-builtin -fno-strict-aliasing -O2 -Wall -MD -ggdb -m32 -march=i686 -Werror -fno-omit-frame-pointer -fno-stack-protector -fno-pie -no-pie -c -o sh.o sh.c

I don't understand what went wrong. All help is appreciated. Thanks in advance.
