There are major downsides too: using multibuild means that local development of such packages is functionally impossible.

You mean because of that nasty @BUILD_FLAVOR@ substitution? I really hope that we can find a sane alternative, like the one I suggest earlier in this thread.

You are also saying it's okay to occupy more builders at a time (which is probably not actually okay to do at scale). You also lose the

OBS is all about parallelization. That's a feature that needs to be leveraged as much as possible :-)

guarantee that the binary artifacts are always in sync, since a failure for one flavor doesn't stop another. That is a subtle kind of breakage that's hard to perceive and fix.

May happen but is a pretty standard problem to have. In fact we have that all the time with different architectures for example. And in the end mingw32 and mingw64 are nothing else than architectures. Just weirdly packaged as there's no general concept of handling cross arch packages. So no nothing special here. Doesn't sound like a big deal to me.

Duplication in the spec is something that is solvable (cf. SUSE-style single-spec for Python and Ruby). But losing understandability and coherence is something I'd rather not see us do.

Like I said, at the expense of more macro magic. I wouldn't consider myself a total novice in rpm macros but what python is doing there is close to witchcraft. That works in a situation where most packages are standard situations, using the same build system etc. Mingw packages are just like any other package in the distro. Ie has to deal with all build systems anyone ever invented means all the quirks and hacks needed to deal with them. On top of that cross compilation hacks. cu Ludwig -- (o_ Ludwig Nussel //\ V_/_ http://www.suse.com/ SUSE Software Solutions Germany GmbH, GF: Felix Imendörffer HRB 36809 (AG Nürnberg) -- To unsubscribe, e-mail: opensuse-buildservice+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse-buildservice+owner@opensuse.org
