usage: $program TARGET_ARCH
This script creates a local cross-compiler, and uses it to
cross-compile an Adélie Linux base system for new architecture.
Steps for introducing new architecture include:
- adding the compiler tripler and arch type to abuild
- adding the arch type detection to apk-tools
- adjusting build rules for packages that are arch aware:
gcc, musl, binutils, easy-kernel
- create new kernel config for easy-kernel
After these steps the initial cross-build can be completed
by running this with the target arch as parameter, e.g.:
./$program aarch64
