With sys-kernel/linux-headers-4.3, compiling x11-wm/mutter-3.22.2 fails with: wayland/meta-wayland-tablet-tool.c:43:37: fatal error: linux/input-event-codes.h: No such file or directory With sys-kernel/linux-headers-4.4, compiling succeeds. This makes sense because input-event-codes.h was added between 4.3 and 4.4: https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=f902dd893427eade90f7eaf858e5ff8b150a5a12 Possibly this only happens with +wayland, I didn't test with -wayland. mutter use flags: -debug -gles2 -input_devices_wacom +introspection -test -udev +wayland relevant part of emerge --info: Portage 2.3.0 (python 3.4.5-final-0, default/linux/amd64/13.0, gcc-5.4.0, glibc-2.22-r4, 4.8.6 x86_64) ================================================================= System uname: Linux-4.8.6-x86_64-Intel-R-_Core-TM-_i7-3770_CPU_@_3.40GHz-with-gentoo-2.2 KiB Mem: 16323700 total, 1067136 free KiB Swap: 0 total, 0 free Timestamp of repository gentoo: Sun, 13 Nov 2016 07:29:32 +0000 sh bash 4.3_p48 ld GNU ld (Gentoo 2.25.1 p1.1) 2.25.1 app-shells/bash: 4.3_p48::gentoo dev-java/java-config: 2.2.0-r3::gentoo dev-lang/perl: 5.22.2::gentoo dev-lang/python: 2.7.12::gentoo, 3.4.5::gentoo dev-util/cmake: 3.6.2::gentoo dev-util/pkgconfig: 0.28-r2::gentoo sys-apps/baselayout: 2.2::gentoo sys-apps/openrc: 0.21.7::gentoo sys-apps/sandbox: 2.10-r1::gentoo sys-devel/autoconf: 2.13::gentoo, 2.69::gentoo sys-devel/automake: 1.11.6-r1::gentoo, 1.14.1::gentoo, 1.15::gentoo sys-devel/binutils: 2.25.1-r1::gentoo sys-devel/gcc: 5.4.0::gentoo sys-devel/gcc-config: 1.7.3::gentoo sys-devel/libtool: 2.4.6::gentoo sys-devel/make: 4.1-r1::gentoo sys-kernel/linux-headers: 4.4::gentoo (virtual/os-headers) sys-libs/glibc: 2.22-r4::gentoo
I can confirm this issue. I solved switching to linux-headers-4.8 as suggested by dolphinling.
Same requirement here on ia64 workstation with global USE=wayland flag. Émeric
Checked -wayland, it is not necessary there. Fixed in commit https://gitweb.gentoo.org/repo/gentoo.git/commit/?id=b6d1847f6177eff0a37fa08994329519ded4a7be Thanks for reporting.
