Per comment #11 on bug #504356, mesa upstream appears to have forced libudev as a requirement for 10.2.x on Linux systems for DRI (non-Linux systems do not need it). Since I am running with mdev on a few of my installs, this results in a build failure, and may need additional patching to resolve: checking if more special flags are required for pthreads... no checking for PTHREAD_PRIO_INHERIT... no checking for LIBDRM... yes checking for LIBUDEV... no checking for GLPROTO... yes checking for DRI2PROTO... yes checking for XF86VIDMODE... yes checking for DRIGL... yes configure: error: libudev-dev required for building DRI !!!

Some observations: * Upstream forces udev only on Linux. This is because they do not want to support udev-less configurations on Linux. * We could simply disable the configure.ac check and issue a warning to the user that mesa might not work properly (e.g. not find the correct driver filename automatically). * Most stuff apparently works without udev, DRI3 being one exception.
I have to wonder how mesa is dealt with in embedded situations where they use mdev. I'm on the buildroot ML, but I don't recall if anything mesa-related involving udev has gone by. I did find this, though: https://bugs.freedesktop.org/show_bug.cgi?id=75212 Per comment #6, would it make sense to have a separate libudev package from udev or eudev to provide the udev support that mesa is looking for?
(In reply to Joshua Kinard from comment #3) [...] > Per comment #6, would it make sense to have a separate libudev package from > udev or eudev to provide the udev support that mesa is looking for? Isn't possible to install udev package even only for using libudev from it and people finally booting using mdev?
I've recommended to _AxS_ that we use the --enable-sysfs flag, which lets the loader query stuff in /sys rather than using libudev.
+ 25 Nov 2014; Ian Stakenvicius (_AxS_) <axs@gentoo.org> + +files/mesa-10.2-sysfs-instead-of-libudev.patch, mesa-10.2.8.ebuild, + mesa-10.3.0.ebuild, mesa-10.3.1.ebuild, mesa-10.3.4.ebuild, metadata.xml: + Added sysfs use flag to allow libudev to be optional on linux, backported to + 10.2.8 for stabilization +
I think 'udev' is better name for USE flags: 1) nothing in tree has 'sysfs' 2) a lot packages have 'udev' USE flags 3) it controls udev dep in mesa ebuilds
