I'm trying to cross-compile a working Gentoo environment to an AMD 64-bit architecture on 32-bit host. I set up the cross-compile environment using the steps on https://quidecco.de/mediawiki/index.php/Converting_Gentoo_to_64-bit, and then tried to emerge ncurses. It fails when invoking make_keys in the build process because it compiles the executable using the target compiler instead of the host compiler. From what I read, the ebuild should be invoking configure with the --with-build-cc to specify the native compiler, which it does not do. Is this a bug in the ncurses ebuild or is crossdev providing some other means for this which I'm missing? Reproducible: Always Steps to Reproduce: 1. Set up cross-compile environment 2. run "emerge ncurses" 3. fail Actual Results: die message Expected Results: no die message, installed package # emerge --info Portage 2.1.3.19 (default-linux/amd64, gcc-4.1.1, unavailable, 2.6.22-gentoo-r2 i686) ================================================================= System uname: 2.6.22-gentoo-r2 i686 AMD Athlon(tm) 64 Processor 3500+ Timestamp of tree: Mon, 19 Nov 2007 17:30:01 +0000 ccache version 2.4 [disabled] app-shells/bash: 3.2_p17 dev-lang/python: 2.4.4-r6, 2.5.1-r2 dev-python/pycrypto: 2.0.1-r6 dev-util/ccache: 2.4-r7 sys-apps/baselayout: 1.12.9-r2 sys-apps/sandbox: 1.2.18.1-r2 sys-devel/autoconf: 2.13, 2.61-r1 sys-devel/automake: 1.5, 1.6.3, 1.7.9-r1, 1.8.5-r3, 1.9.6-r2, 1.10 sys-devel/binutils: 2.18-r1 sys-devel/gcc-config: 1.3.16 sys-devel/libtool: 1.5.24 virtual/os-headers: 2.6.22-r2 ACCEPT_KEYWORDS="amd64" CBUILD="x86_64-pc-linux-gnu" CFLAGS="-O2 -march=athlon64 -mtune=athlon64" CHOST="i686-pc-linux-gnu" CONFIG_PROTECT="/etc" CONFIG_PROTECT_MASK="/etc/env.d /etc/gconf" CXXFLAGS="-O2 -march=athlon64 -mtune=athlon64" DISTDIR="/usr/portage/distfiles" FEATURES="distlocks metadata-transfer sandbox sfperms strict unmerge-orphans userfetch" GENTOO_MIRRORS="ftp://mirror.pacific.net.au/linux/Gentoo http://mirror.qubenet.net/mirror/gentoo/ http://mirror.etf.bg.ac.yu/gentoo" MAKEOPTS="-j2" PKGDIR="/usr/portage/packages" PORTAGE_RSYNC_OPTS="--recursive --links --safe-links --perms --times --compress --force --whole-file --delete --delete-after --stats --timeout=180 --exclude=/distfiles --exclude=/local --exclude=/packages --filter=H_**/files/digest-*" PORTAGE_TMPDIR="/var/tmp" PORTDIR="/usr/portage" SYNC="rsync://rsync.gentoo.org/gentoo-portage" USE="amd64 berkdb bitmap-fonts cli cracklib crypt dri fortran iconv ipv6 isdnlog midi mudflap ncurses nls openmp pam pcre perl pppd python readline reflection session spl ssl tcpd truetype-fonts type1-fonts xorg zlib" ALSA_CARDS="ali5451 als4000 atiixp atiixp-modem bt87x ca0106 cmipci emu10k1x ens1370 ens1371 es1938 es1968 fm801 hda-intel intel8x0 intel8x0m maestro3 trident usb-audio via82xx via82xx-modem ymfpci" ALSA_PCM_PLUGINS="adpcm alaw asym copy dmix dshare dsnoop empty extplug file hooks iec958 ioplug ladspa lfloat linear meter mulaw multi null plug rate route share shm softvol" ELIBC="glibc" INPUT_DEVICES="keyboard" KERNEL="linux" LCD_DEVICES="bayrad cfontz cfontz633 glk hd44780 lb216 lcdm001 mtxorb ncurses text" USERLAND="GNU" VIDEO_CARDS="apm ark chips cirrus cyrix dummy fbdev glint i128 i810 mach64 mga neomagic nv r128 radeon rendition s3 s3virge savage siliconmotion sis sisusb tdfx tga trident tseng v4l vesa vga via vmware voodoo" Unset: CPPFLAGS, CTARGET, EMERGE_DEFAULT_OPTS, INSTALL_MASK, LANG, LC_ALL, LDFLAGS, LINGUAS, PORTAGE_COMPRESS, PORTAGE_COMPRESS_FLAGS, PORTAGE_RSYNC_EXTRA_OPTS, PORTDIR_OVERLAY

your setup is incorrect you say you're converting from 32bit to 64bit, yet you set your CBUILD to x86_64-pc-linux-gnu which means anything x86_64-pc-linux-gnu produces has to be executable at build time
