Building Oasis Linux from Alpine Linux

building-oasis-linux-on-alpine.md

Following the official install instructions I built Oasis under Alpine Linux (which already uses musl libc), requiring the following:

Notes:

• Needed to symlink lua to lua5.4
• Built in a few minutes
• Resulting binaries (with no toolchain) totaled 82 MB
• Full source, build objects, Git overhead, etc. added roughly 1.5 GB
• I didn't build a kernel or add a bootloader since I was planning to use this in a chroot or container

Dependencies:

apk add binutils bison cc curl git gzip linux-headers lua ninja tzdata-utils pax xz zutils

config.lua: Needed to set platform and cc (note the second key was not present in the template!)

target={
  platform='x86_64-alpine-linux-musl-gcc',
  cc='x86_64-alpine-linux-musl-gcc',
