Let me rephrase my questions: Which specific options do distros want? All of the ones we have as optional dependencies already, or just a specific subset, or something else? In the past we had options like "only build the tools" because someone asked for that, and that also doens't exist anymore iirc. -Daniel -- Daniel Vetter Software Engineer, Intel Corporation http://blog.ffwll.ch ___ xorg@lists.x.org: X.Org support Archives: http://lists.freedesktop.org/archives/xorg Info: https://lists.x.org/mailman/listinfo/xorg Your subscription address: %(user_address)s

What would distro's want from the meson build (since I think it's > useful to cut down a bit from the all the options, mostly they didn't > really work after a short while anyway)? That works fine for developers building it out of their ~/projects directory, but not so well for distros. Source distros in particular don't work well with so-called "automagic" dependencies, i.e., those that are enabled if detected by the configure script without the ability to explicitly disable them. Gentoo's dependency tracking works by saying "Depend on package XYZ iff support for XYZ is requested". Automagic deps break this by assumption by linking with XYZ if it happens to be installed even if support isn't requested. If we just want to make everything required, then... I guess that will work. But because autotools already has configuration support, the source code is already ready. FWIW, this came to my attention recently because I worked with the Chrome team at Intel to add v1.22 to Gentoo. I suggested switching to Meson and then realized it wasn't configurable at all. ___ xorg@lists.x.org: X.Org support Archives: http://lists.freedesktop.org/archives/xorg Info: https://lists.x.org/mailman/listinfo/xorg Your subscription address: %(user_address)s
