Debian Conference 2015 The annual Debian developer meeting

Discussion of the state of Multiarch, Crossbuilding, Bootstrapping, and Cross-toolchains in Debian. There has been good progress in these areas recently, but numerous issues remain, such as Multiarch dpkg/apt/aptitude inconsistencies, cross-dependencies, and how Cross-toolchains in the archive should look.

Not everyone is interested in all of this so the session will be spit into chunks: 11:00 Multiarch 13:00 Crossbuilding and bootstraping 15:00 Cross-toolchain packaging

Agenda:

Multiarch things:

• Multiarch (not!) in Policy
• dpkg/apt/aptitude inconsistencies
• cross-dependencies
• bootstrapping-related issues
• embedded interpreter problem

Agreement on the correct interpretations of some things is needed:

1) if a package foo with arch:A depends on bar:any where bar is m-a:no and arch:A, is that dependency satisfied?

2) Do we accept https://wiki.debian.org/Multiarch/InterpreterProposal? If not what should we do instead?

3) Should we declare 666772 (apt cross-build-dep handling should be liberal with Arch: all packages) wontfix officially (and document corollary) ?

Crossbuilding:

General roadmap - what still needs doing?

Feedback from users on what we have so far is very welcome.

• Cross-dependencies
• Multiarching more packages
• toolchain support packages
• Cmake crossing - state?
• Using build profiles
• sbuild issues
• Documentation

Bootstrapping

Followup from Helmut's talk on Monday.

Cross-Toolchains

gcc-5 uses -cross standalone packages gcc-4.9 uses wdotap multiarch packages

• Everyone happy with standalone packages?

• Should cross-toolchains be multibbed?

• What set of toolchains should be pre-built in the archive?

• What about toolchains not provided as binaries? Cross-gcc source-generator OK?

• What ancilliary packages are needed?
