# Main makefile for the toolchain

|
# Steps:
|
|
# 1) toolchain/binutils/compile
|
|
# build & install binutils
|
|
# 2) toolchain/gcc/minimal/compile
|
|
# build & install a minimal gcc, needed for steps 3 & 4
|
|
# 3) toolchain/kernel-headers/compile
|
|
# install kernel headers, needed for step 4
|
|
# 4) toolchain/libc/headers/compile
|
|
# build & install libc headers & support files, needed for step 5
|
|
# 5) toolchain/gcc/initial/compile
|
|
# build & install an initial gcc, needed for step 6
|
|
# 6) toolchain/libc/compile
|
|
# build & install the final libc
|
|
# 7) toolchain/gcc/final/compile
|
|
# build & install the final gcc
|
|
# 8) toolchain/libc/utils/compile
|
|
# build & install libc utilities
|
|
#
|
|
# For musl, steps 2 and 4 are skipped, and step 3 is done after 5
