After building the toolchain, emerging gcc natively for the target-system, so it can be used later on the system itself, it encounters errors, that can be avoided by filtering out cpu specific CFLAGS (in my case -mtune and -mcpu). If not filtering out, configure stops.
Reopen with some errors, a lot more useful that describing it... :)
Here is my make.conf #If this line is used, getting errors CFLAGS="-Os -mcpu=405 -mtune=405 -fomit-frame-pointer -pipe" #If this, compiles cleanly #CFLAGS="-Os -fomit-frame-pointer -pipe" CXXFLAGS="${CFLAGS}" CHOST="powerpc-softfloat-linux-uclibc" CBUILD="i686-pc-linux-gnu" CTARGET="powerpc-softfloat-linux-uclibc" USE="-gpm -pcre -crypt -ldap -nls -X -ipv6" ACCEPT_KEYWORDS="-* ppc" ERRORS: ... checking build system type... i686-pc-linux-gnu checking host system type... i686-pc-linux-gnu checking for i686-pc-linux-gnu-ar... i686-pc-linux-gnu-ar checking for i686-pc-linux-gnu-ranlib... i686-pc-linux-gnu-ranlib checking for i686-pc-linux-gnu-gcc... gcc checking for suffix of object files... configure: error: cannot compute suffix of object files: cannot compile See `config.log' for more details. make: *** [configure-build-libiberty] Error 1 !!!

First some things for the BUILD, then for the HOST. For the BUILD-stage, there must be some flags filtered out. For now, I'm happy without -mtune and -mcpu, because of the possibility to recompile gcc on the target with flags. emerge --info Portage 2.1.1 (!../usr/local/profiles/uclibc/ppc-softfloat/2.6, gcc-3.4.6, uclibc-0.9.28-r0, 2.6.17-gentoo-r7 i686) ================================================================= System uname: 2.6.17-gentoo-r7 i686 Intel(R) Pentium(R) 4 CPU 2.80GHz Gentoo Base System version 1.12.5 Last Sync: Sat, 30 Sep 2006 03:00:01 +0000 distcc 2.18.3 i686-pc-linux-gnu (protocols 1 and 2) (default port 3632) [disabled] ccache version 2.3 [disabled] app-admin/eselect-compiler: [Not Present] dev-java/java-config: 1.2.11-r1 dev-lang/python: 2.4.3-r1 dev-python/pycrypto: 2.0.1-r5 dev-util/ccache: 2.3 dev-util/confcache: [Not Present] sys-apps/sandbox: 1.2.17 sys-devel/autoconf: 2.13, 2.59-r7 sys-devel/automake: 1.4_p6, 1.5, 1.6.3, 1.7.9-r1, 1.8.5-r3, 1.9.6-r2 sys-devel/binutils: 2.16.1-r3 sys-devel/gcc-config: 1.3.13-r3 sys-devel/libtool: 1.5.22 virtual/os-headers: 2.6.17-r1 ACCEPT_KEYWORDS="ppc" AUTOCLEAN="yes" CBUILD="i686-pc-linux-gnu" CFLAGS="-Os -mcpu=405 -mtune=405 -fomit-frame-pointer -pipe" CHOST="powerpc-softfloat-linux-uclibc" CONFIG_PROTECT="/etc /usr/kde/3.4/env /usr/kde/3.4/share/config /usr/kde/3.4/shutdown /usr/kde/3.5/env /usr/kde/3.5/share/config /usr/kde/3.5/shutdown /usr/share/X11/xkb /usr/share/config /usr/share/texmf/dvipdfm/config/ /usr/share/texmf/dvips/config/ /usr/share/texmf/tex/generic/config/ /usr/share/texmf/tex/platex/config/ /usr/share/texmf/xdvi/ /var/Projekte/ppc-embedded/etc" CONFIG_PROTECT_MASK="/etc/env.d /etc/gconf /etc/revdep-rebuild /etc/terminfo" CTARGET="powerpc-softfloat-linux-uclibc" CXXFLAGS="-Os -mcpu=405 -mtune=405 -fomit-frame-pointer -pipe" DISTDIR="/usr/portage/distfiles" FEATURES="autoconfig distlocks metadata-transfer nodoc noinfo noman sandbox sfperms strict" GENTOO_MIRRORS="ftp://linux.rz.ruhr-uni-bochum.de/gentoo-mirror/ ftp://ftp.uni-erlangen.de/mirrors/gentoo" LINGUAS="" 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'" PORTAGE_TMPDIR="/var/tmp" PORTDIR="/usr/portage" SYNC="rsync://rsync.gentoo.org/gentoo-portage" USE="ppc bitmap-fonts cli dlloader dri elibc_uclibc input_devices_evdev input_devices_keyboard input_devices_mouse kernel_linux ncurses readline reflection session spl truetype-fonts type1-fonts uclibc userland_GNU video_cards_dummy video_cards_fbdev video_cards_v4l xorg zlib" Unset: EMERGE_DEFAULT_OPTS, INSTALL_MASK, LANG, LC_ALL, LDFLAGS, MAKEOPTS, PORTAGE_RSYNC_EXTRA_OPTS, PORTDIR_OVERLAY
Could you attach the config.log it references in the error (if you are still even having this problem)?
(In reply to comment #3) Sorry, takes to mauch time to set this up again for the moment... Perhaps I can do it in 1 or 2 weeks...
