#33259: cmake portgroup: out of source build option, possibly by default ---------------------------+-------------------------------- Reporter: ryandesign@… | Owner: macports-tickets@… Type: enhancement | Status: new Priority: Normal | Milestone: Component: ports | Version: Resolution: | Keywords: Port: | ---------------------------+-------------------------------- Comment (by larryv@…): Replying to [comment:48 rjvbertin@…]:

Is there or has there ever been a cmake-0.0 portgroup? I'd feel more comfortable moving the old default behaviour to a "previous version"

What? This would be weird and confusing.

rather than obliging everyone to delve into their portfiles or portgroup files to bump a version when their products just work with the new OOS approach. It also means that maintainers who do nothing will keep using non-OOS builds

Yes, that’s what Michael and I want because we don’t know that all the portfiles will “just work”. So the question is whether this should be opt- in or opt-out. If we decided on opt-out, we already have a simple implementation: Change the default in `cmake-1.0` and be done with it. Ports that can’t deal with the default behavior would just add “`cmake.out_of_source no`”.

which kind of goes against the very reasons OOS builds were made the default

I don’t agree. The point of portgroups is to cut down on portfile boilerplate, not necessarily to reduce maintainer effort. Also: Given that this modification would change the default build behavior, I think it’d be a good thing to require portfiles to be updated for it. It’s confusing when a port’s behavior mysteriously changes because of portgroup action-at-a-distance, especially if it breaks. This happens all too often, and it can be difficult to debug.

Note that demoting the current default to a legacy portgroup also means there is no or less reason to port other modifications to it...

I think maintaining parallel portgroups is a minor problem. Forgetting to change one or the other would not be the end of the world; someone else could just clean up afterwards. -- Ticket URL: <https://trac.macports.org/ticket/33259#comment:49> MacPorts <https://www.macports.org/> Ports system for OS X
