Created attachment 513120 [details] build.log I recently switched to the new 17.1 profile and did a complete world-rebuild, including gcc. All packages compiled successfully, with the exception of glibc. The versions of glibc I tried emerging were 2.26-r3 and 2.26-r5, both failing the same way: Right at the beginning of compilation, it complains about not finding stddef.h and stdbool.h. I suspect it has something to do with the order I emerged glibc and gcc during the world-rebuild, possibly removing something from which the ebuild cannot recover from. Attached you can find the full build-log and the following is my emerge --info: Portage 2.3.19 (python 3.5.4-final-0, default/linux/amd64/17.1, gcc-7.2.0, glibc-2.26-r3, 4.14.9 x86_64) ================================================================= System uname: Linux-4.14.9-x86_64-Intel-R-_Core-TM-_i7-3720QM_CPU_@_2.60GHz-with-gentoo-2.4.1 KiB Mem: 16305044 total, 349472 free KiB Swap: 0 total, 0 free Timestamp of repository gentoo: Wed, 03 Jan 2018 18:30:01 +0000 Head commit of repository gentoo: 0012abc6273f02d8932dbf833522416694ee9dff sh bash 4.4_p12 ld GNU ld (Gentoo 2.29.1 p3) 2.29.1 app-shells/bash: 4.4_p12::gentoo dev-java/java-config: 2.2.0-r3::gentoo dev-lang/perl: 5.26.1-r1::gentoo dev-lang/python: 2.7.14-r1::gentoo, 3.5.4-r1::gentoo dev-util/cmake: 3.10.1::gentoo dev-util/pkgconfig: 0.29.2::gentoo sys-apps/baselayout: 2.4.1-r2::gentoo sys-apps/openrc: 0.34.11::gentoo sys-apps/sandbox: 2.12::gentoo sys-devel/autoconf: 2.13::gentoo, 2.69-r4::gentoo sys-devel/automake: 1.15.1-r1::gentoo sys-devel/binutils: 2.29.1-r1::gentoo sys-devel/gcc: 7.2.0::gentoo sys-devel/gcc-config: 1.9.1::gentoo sys-devel/libtool: 2.4.6-r4::gentoo sys-devel/make: 4.2.1-r1::gentoo sys-kernel/linux-headers: 4.14::gentoo (virtual/os-headers) sys-libs/glibc: 2.26-r3::gentoo Repositories: gentoo location: /usr/portage sync-type: rsync sync-uri: rsync://rsync.gentoo.org/gentoo-portage priority: -1000 sync-rsync-extra-opts: x-portage location: /usr/local/portage masters: gentoo priority: 0 local-crossdev location: /usr/portage-musl masters: gentoo priority: 9999 ACCEPT_KEYWORDS="amd64 ~amd64" ACCEPT_LICENSE="@FREE" CBUILD="x86_64-pc-linux-gnu" CFLAGS="-march=native -O2 -pipe" CHOST="x86_64-pc-linux-gnu" CONFIG_PROTECT="/etc /usr/share/gnupg/qualified.txt" CONFIG_PROTECT_MASK="/etc/ca-certificates.conf /etc/dconf /etc/env.d /etc/fonts/fonts.conf /etc/gconf /etc/gentoo-release /etc/revdep-rebuild /etc/sandbox.d /etc/terminfo /etc/texmf/language.dat.d /etc/texmf/language.def.d /etc/texmf/updmap.d /etc/texmf/web2c" CXXFLAGS="-march=native -O2 -pipe" DISTDIR="/usr/portage/distfiles" EMERGE_DEFAULT_OPTS="--keep-going --with-bdeps=y --quiet-build=y --color=y --complete-graph" FCFLAGS="-O2 -pipe" FEATURES="assume-digests binpkg-logs config-protect-if-modified distlocks ebuild-locks fixlafiles merge-sync multilib-strict news parallel-fetch preserve-libs protect-owned sandbox sfperms strict unknown-features-warn unmerge-logs unmerge-orphans userfetch userpriv usersandbox usersync" FFLAGS="-O2 -pipe" GENTOO_MIRRORS="http://distfiles.gentoo.org" LANG="en_US.UTF-8" LDFLAGS="-Wl,-O1 -Wl,--as-needed" MAKEOPTS="-j8 -l4" PKGDIR="/usr/portage/packages" PORTAGE_CONFIGROOT="/" PORTAGE_RSYNC_OPTS="--recursive --links --safe-links --perms --times --omit-dir-times --compress --force --whole-file --delete --stats --human-readable --timeout=180 --exclude=/distfiles --exclude=/local --exclude=/packages --exclude=/.git" PORTAGE_TMPDIR="/var/tmp" USE="alsa amd64 bzip2 cli colord crypt cups cxx dri iconv ipv6 lcms multilib ncurses nptl offensive openmp readline seccomp ssl tk unicode zlib" ABI_X86="64 32" ALSA_CARDS="usb-audio" APACHE2_MODULES="authn_core authz_core socache_shmcb unixd actions alias auth_basic authn_alias authn_anon authn_dbm authn_default authn_file authz_dbm authz_default authz_groupfile authz_host authz_owner authz_user autoindex cache cgi cgid dav dav_fs dav_lock deflate dir disk_cache env expires ext_filter file_cache filter headers include info log_config logio mem_cache mime mime_magic negotiation rewrite setenvif speling status unique_id userdir usertrack vhost_alias" CALLIGRA_FEATURES="kexi words flow plan sheets stage tables krita karbon braindump author" COLLECTD_PLUGINS="df interface irq load memory rrdtool swap syslog" CPU_FLAGS_X86="aes avx f16c mmx mmxext popcnt sse sse2 sse3 sse4_1 sse4_2 ssse3" ELIBC="glibc" GPSD_PROTOCOLS="ashtech aivdm earthmate evermore fv18 garmin garmintxt gpsclock isync itrax mtk3301 nmea ntrip navcom oceanserver oldstyle oncore rtcm104v2 rtcm104v3 sirf skytraq superstar2 timing tsip tripmate tnt ublox ubx" INPUT_DEVICES="keyboard mouse joystick evdev" KERNEL="linux" L10N="en en_US" LCD_DEVICES="bayrad cfontz cfontz633 glk hd44780 lb216 lcdm001 mtxorb ncurses text" LIBREOFFICE_EXTENSIONS="presenter-console presenter-minimizer" LINGUAS="en en_US" OFFICE_IMPLEMENTATION="libreoffice" PHP_TARGETS="php5-6 php7-0" POSTGRES_TARGETS="postgres9_5" PYTHON_SINGLE_TARGET="python3_5" PYTHON_TARGETS="python2_7 python3_5" RUBY_TARGETS="ruby24 ruby25" USERLAND="GNU" VIDEO_CARDS="intel i915 i965" XTABLES_ADDONS="quota2 psd pknock lscan length2 ipv4options ipset ipp2p iface geoip fuzzy condition tee tarpit sysrq steal rawnat logmark ipmark dhcpmac delude chaos account" Unset: CC, CPPFLAGS, CTARGET, CXX, INSTALL_MASK, LC_ALL, PORTAGE_BUNZIP2_COMMAND, PORTAGE_COMPRESS, PORTAGE_COMPRESS_FLAGS, PORTAGE_RSYNC_EXTRA_OPTS

It failed the same way; With -v added, it gives the following output: Using built-in specs.

No, /usr/local/include only contains some old headers for local things (wayland-headers for testing, toxcore-headers), but nothing that would fool system headers in any way. > 3. What does 'find /usr/ -name stddef.h' find? Modulo headers found within /usr/local/MATLAB, /usr/gnat and /usr/src/linux* (which are obviously not of interest), it finds stddef.h in the following places: /usr/x86_64-pc-linux-musl/usr/include/linux/stddef.h /usr/x86_64-pc-linux-musl/usr/include/stddef.h /usr/lib/gcc/x86_64-pc-linux-musl/7.2.0/include/stddef.h /usr/lib/gcc/x86_64-pc-linux-gnu/7.2.0/include/stddef.h /usr/lib/clang/5.0.1/include/stddef.h /usr/share/syslinux/com32/include/bitsize32/stddef.h /usr/share/syslinux/com32/include/stddef.h /usr/share/syslinux/com32/include/bitsize64/stddef.h /usr/share/syslinux/com32/include/bitsize/stddef.h /usr/include/linux/stddef.h /usr/include/c++/v1/stddef.h /usr/include/wine-vanilla-2.20/wine/msvcrt/stddef.h /usr/include/wine-d3d9-2.19/wine/msvcrt/stddef.h /usr/include/wine-staging-2.19/wine/msvcrt/stddef.h Again, we can probably highlight the /usr/lib/gcc/x86_64-pc-linux-gnu/7.2.0/include/ folder we talked about before.
Okay, I think I found the problem. The glibc-emerge works as soon as I renamed the "/usr/lib/include" folder to something else. You might want to test this by issuing mkdir /usr/lib/include and then checking if the emerge fails for you on the 17.1 profile. Of course I won't set this to resolved, as the emerge obviously should not fail when this folder is present.

'mkdir /usr/lib/include' breaks glibc the same for me. It's caused by the following code: https://sourceware.org/git/?p=glibc.git;a=blob;f=configure.ac;h=ca1282a6b3f8c5369c133a47f5c8239c3f2d32b5;hb=HEAD#l1018 where glibc tries hard to use only two system include paths (and not all include paths gcc knows about): one include and one include-fixed.

Very interesting. Well, it seems like it made sense to test the 17.1 with an "old" Gentoo-system with a lot of cruft (it's now almost 6 years old). I'll stay tuned for the fix in the ebuild.
*** Bug 687468 has been marked as a duplicate of this bug. ***
I did not get to in in 2 years and did not come up with a cheap check in glibc or in ebuilds. Let's close it as WONTFIX and deal with user's build breakages on case-by-case basis.

Very nice, thank you very much! This bug was definitely an oddity, and I'm glad to see it fixed.
