After reading #Ueber’s post about their use of #Zig, I tried it to random C and C++ projects:

export CC="zig cc"
export CXX="zig c++"
make

At least for relatively small projects such as nnn this seems to result working results. Still quite impressive. Next iteration would to replace Makefile with build.rs.

Also one tool that I like, ncdu, has successfully executed such conversion: https://dev.yorhel.nl/ncdu

I think I’ll try Linux with tinyconfig next by using this hacky script as basis next:

#!/usr/bin/env bash

set -e

make defconfig
scripts/config --set-str CONFIG_INITRAMFS_SOURCE "initramfs.txt"
yes '' | make oldconfig

cat > initramfs.txt << EOF
dir /dev 755 0 0
nod /dev/console 644 0 0 c 5 1
nod /dev/loop0 644 0 0 b 7 0
dir /bin 755 1000 1000
slink /bin/sh busybox 777 0 0
file /bin/busybox initramfs/busybox 755 0 0
dir /proc 755 0 0
dir /sys 755 0 0
dir /mnt 755 0 0
file /init initramfs/init.sh 755 0 0
EOF

mkdir initramfs

curl -sSf https://dl-cdn.alpinelinux.org/alpine/edge/main/x86_64/busybox-static-1.36.1-r25.apk | tar zx --strip-components 1
cp busybox.static initramfs/busybox

cat > initramfs/init.sh << EOF
#!/bin/sh
mount -t proc none /proc
mount -t sysfs none /sys
sh
EOF

It is from my old’ish post: https://social.kernel.org/notice/AgzHqrYFGplZuYr3gG
