Hi Emil, I would like to revive an idea from a few years ago: > Drop the "auto" all-together. > > It adds a _ton_ of complexity while making the build semi-magical/not > as deterministic. >
I can certainly sympathize here. I maintain a ton of build infrastructure for a wide variety of projects and the whole "auto" thing is realy a pain to deal with from both an implementation and maintenance perspective. > The only downside is that we may need to tweak our scripts _once_ to > list exactly what we want to build ;-) > That's be nice, but it's simply not reality. For the past several years I've neaded to tweak our mesa builds scripts every few releases. I don't think that's particularly a problem so I'm not raising it as an issue, just that the config options are regularly evolving, which is okay, theyre not static though. > IIRC the Gnome people have been actively working for removing such > autodetection in their packages. > ... > Distributions already explicitly specify what they want and most of > our autodetection is effectively a bad copy of that. > The big difference vs gnome is that *most* gnome packages are consumed by users only as system libraries and thus package maintainers are the ones build them, so it's not a big deal to have to explicitly configure it how you want. Seldom will you have a miscelaneous user needing to build and use thier own version of GNOME libs. Mesa, on the other hand, has an extensive set of users just like that. A substantial portion of mesa's user base are graphics developers that have no idea what most of the mesa options are or what they do, but just need to have a new mesa build to fix a bug their OpenGL code is hitting. As much as dealing with the "auto" implementation sucks, I think it's important that the default out-of-the-box with no arguments configuration should be sane and likely to produce something useful, even if not optimal. - Chuck
