Description
I'm on MacOS Monterey, and this is the output of rustup show
Default host: x86_64-apple-darwin
rustup home: /Users/andre/.rustup
installed toolchains
--------------------
stable-x86_64-apple-darwin
nightly-x86_64-apple-darwin (default)
active toolchain
----------------
nightly-x86_64-apple-darwin (overridden by '/Users/andre/Desktop/xv6-rust/rust-toolchain')
rustc 1.67.0-nightly (e75aab045 2022-11-09)
I also already had i386-elf-gcc installed:
$ i386-elf-gcc -v
Using built-in specs.
COLLECT_GCC=i386-elf-gcc
COLLECT_LTO_WRAPPER=/usr/local/Cellar/i386-elf-gcc/11.2.0_1/libexec/gcc/i386-elf/11.2.0/lto-wrapper
Target: i386-elf
Configured with: ../configure --prefix=/usr/local/Cellar/i386-elf-gcc/11.2.0_1 --target=i386-elf --disable-multilib --disable-nls --disable-werror --without-headers --without-isl --enable-languages=c,c++
Thread model: single
Supported LTO compression algorithms: zlib zstd
gcc version 11.2.0 (GCC)
Did a few modifications on Makefile
CC := i386-elf-gcc
LD := i386-elf-ld
OBJDUMP := i386-elf-objdump
OBJCOPY := i386-elf-objcopy
NM := i386-elf-nm
AR := i386-elf-ar
And also changed the content of rust-toolchain file:
nightly-x86_64-apple-darwin
OK, let's try make all. Got this:
i386-elf-nm -n obj/user/wc > obj/user/wc.sym
