Created attachment 454128 [details, diff] patch for llvm 3.9.0 to work on arm64 for abi="arm64" the line: local abi_chost=$(get_abi_CHOST "${abi}") will return an empty CHOST which is used and not checked to create symlinks in /usr/bin/. Here is a patch attached to guard against that, because the symlinks are not so important if one does not cross compile for that architecture. A better way would be to repair get_abi_CHOST on arm64. == emerge Info: Portage 2.3.0 (python 3.4.3-final-0, default/linux/arm64/13.0, gcc-5.4.0, glibc-2.22-r4, 4.8.7-gentoo aarch64) ================================================================= System uname: Linux-4.8.7-gentoo-aarch64-with-gentoo-2.2 KiB Mem: 131943496 total, 128095004 free KiB Swap: 0 total, 0 free Timestamp of repository gentoo: Wed, 23 Nov 2016 13:30:01 +0000 sh bash 4.3_p48 ld GNU ld (Gentoo 2.25.1 p1.1) 2.25.1 ccache version 3.2.4 [enabled] app-shells/bash: 4.3_p48::gentoo dev-lang/perl: 5.20.2::gentoo dev-lang/python: 2.7.10-r1::gentoo, 3.4.3-r1::gentoo dev-util/ccache: 3.2.4::gentoo dev-util/cmake: 3.7.0::gentoo dev-util/pkgconfig: 0.28-r2::gentoo sys-apps/baselayout: 2.2::gentoo sys-apps/openrc: 0.19.1::gentoo sys-apps/sandbox: 2.10-r1::gentoo sys-devel/autoconf: 2.69::gentoo sys-devel/automake: 1.14.1::gentoo, 1.15::gentoo sys-devel/binutils: 2.25.1-r1::gentoo sys-devel/gcc: 4.9.3::gentoo, 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: 4.3::gentoo (virtual/os-headers) sys-libs/glibc: 2.22-r4::gentoo Repositories: gentoo location: /usr/portage sync-type: rsync sync-uri: rsync://rsync.gentoo.org/gentoo-portage priority: -1000 rust location: /var/lib/layman/rust masters: gentoo priority: 0 ACCEPT_KEYWORDS="arm64" ACCEPT_LICENSE="*" CBUILD="aarch64-unknown-linux-gnu" CFLAGS="-O2 -pipe -mtune=thunderx" CHOST="aarch64-unknown-linux-gnu" CONFIG_PROTECT="/etc /usr/share/gnupg/qualified.txt" CONFIG_PROTECT_MASK="/etc/ca-certificates.conf /etc/env.d /etc/fonts/fonts.conf /etc/gconf /etc/gentoo-release /etc/revdep-rebuild /etc/sandbox.d /etc/terminfo" CXXFLAGS="-O2" DISTDIR="/usr/portage/distfiles" FCFLAGS="-O2" FEATURES="assume-digests binpkg-logs buildsyspkg ccache config-protect-if-modified distlocks ebuild-locks fixlafiles merge-sync news parallel-fetch preserve-libs protect-owned sandbox sfperms splitdebug strict unknown-features-warn unmerge-logs unmerge-orphans userfetch userpriv usersandbox usersync xattr" FFLAGS="-O2" GENTOO_MIRRORS="http://distfiles.gentoo.org" LANG="en_US.UTF-8" LDFLAGS="-Wl,-O1 -Wl,--as-needed" MAKEOPTS="-j96" 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="acl arm64 berkdb bzip2 cli cracklib crypt cxx dri fortran gdbm iconv modules multilib ncurses nls nptl openmp pam pcre readline seccomp session ssl tcpd unicode xattr zlib" 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" CAMERAS="ptp2" COLLECTD_PLUGINS="df interface irq load memory rrdtool swap syslog" ELIBC="glibc" GPSD_PROTOCOLS="ashtech aivdm earthmate evermore fv18 garmin garmintxt gpsclock itrax mtk3301 nmea ntrip navcom oceanserver oldstyle oncore rtcm104v2 rtcm104v3 sirf superstar2 timing tsip tripmate tnt ublox ubx" INPUT_DEVICES="keyboard mouse evdev" KERNEL="linux" LCD_DEVICES="bayrad cfontz cfontz633 glk hd44780 lb216 lcdm001 mtxorb ncurses text" LIBREOFFICE_EXTENSIONS="presenter-console presenter-minimizer" OFFICE_IMPLEMENTATION="libreoffice" PHP_TARGETS="php5-6" PYTHON_SINGLE_TARGET="python2_7" PYTHON_TARGETS="python2_7 python3_4" RUBY_TARGETS="ruby20 ruby21" USERLAND="GNU" VIDEO_CARDS="fbdev dummy v4l" 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, EMERGE_DEFAULT_OPTS, INSTALL_MASK, LC_ALL, PORTAGE_BUNZIP2_COMMAND, PORTAGE_COMPRESS, PORTAGE_COMPRESS_FLAGS, PORTAGE_RSYNC_EXTRA_OPTS, USE_PYTHON
The arch profile should be ensuring that CHOSTs are set correctly. I'm not really interested in working that around in random applications.
note: proposed profile fix: https://bugs.gentoo.org/show_bug.cgi?id=602466 fixing CHOST issues
commit 3977562864163fc4887ab1f59a3c92ac7ea4bb6d Author: Michał Górny <mgorny@gentoo.org> AuthorDate: Sat Jan 14 18:54:34 2017 Commit: Michał Górny <mgorny@gentoo.org> CommitDate: Sat Jan 14 19:14:24 2017 profiles/default/linux/arm64: Fix parent to little-endian, #600590 Fix the parent profile of default/linux/arm64 from top-level arch/arm64 to little-endian subprofile. This is what the profile structure suggests, and (unlike the top profile) it defines CHOST (and CHOST_arm64) as required by package manager, eclasses and ebuilds. profiles/default/linux/arm64/parent | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-)
