Instead of apk adding dependencies to sysroot, use the EXTRADEPENDS_TARGET to pass in these dependencies. This does not leave the sysroot in dirty state, but instead cleans it up.

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

|
