Cross-Compilation Environment
Continue improving Cross Compilation tools:
- get usage scenarios from cross-build tool users
- address issues observed from cross-building ALIP packages with xdeb and pdebuild-cross
(packages with broken cross-support, strip issues with native libs, xdeb package-crossing fails on some packages)
- consider multiarch integration and how that affects approach (cross-dep metadata, new paths, timescales for change)
- Need to make package-config have arch-dependent binaries (see http://
- consider pros/cons of one capable, monolithic tool vs a set of integrated 'do one job well' tools:
(Cross-dep satisfier, build-recurser, package-crosser, cross-builder, bootstrapper, source downloader, package uploader)
- management/use of internal/external repositories
- xdeb issues: caching/rebuild behaviour with --only-explicit, packages that fail to cross
