Build fails with fortran/arith.c:52: undefined reference to `mpfr_get_z_2exp', so it seems libmpfr related. Reproducible: Always Steps to Reproduce: 1. Unmask sys-devel/gcc-4.6.1-r1 2. emerge -1 gcc Actual Results: Build fails. Expected Results: Successful emerge. My amd64 box at work runs Ubuntu 10.04 and I set up Gentoo Prefix in my home. Due to bug 362315 , I had to enable USE=vanilla for gcc-4.6.1-r1, Since this could be libmpfr related (mpfr_get_z_exp has been renamed mpfr_get_z_2exp somewhen in the past): My prefix installation uses def-libs/libmpfr-3.0.1 and dev-libs/mpc-0.9. emerge --info: Portage 2.2.01.19572-prefix (prefix/linux/amd64, gcc-4.5.3, unavailable, 2.6.32-34-generic x86_64) ================================================================= System uname: Linux-2.6.32-34-generic-x86_64-Dual_Core_AMD_Opteron-tm-_Processor_280-with-debian-squeeze-sid Timestamp of tree: Tue, 08 Nov 2011 06:10:01 +0000 app-shells/bash: 4.2_p10 dev-lang/python: 2.7.2 dev-util/cmake: 2.8.6-r3 dev-util/pkgconfig: 0.26 sys-devel/autoconf: 2.68 sys-devel/automake: 1.11.1 sys-devel/binutils: 2.21.53.0.2 sys-devel/gcc: 4.5.3-r1 sys-devel/gcc-config: 1.4.1-r00.2 sys-devel/libtool: 2.4-r4 sys-devel/make: 3.82 Repositories: gentoo_prefix x-local_ebuilds Installed sets: ACCEPT_KEYWORDS="~amd64 ~amd64-linux" ACCEPT_LICENSE="* -@EULA" CBUILD="x86_64-pc-linux-gnu" CFLAGS="-O2 -pipe -fomit-frame-pointer" CHOST="x86_64-pc-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/portage /etc/revdep-rebuild /etc/terminfo" CXXFLAGS="-O2 -pipe -fomit-frame-pointer" DISTDIR="/home/paul/gentoo/usr/portage/distfiles" FEATURES="assume-digests binpkg-logs collision-protect distlocks ebuild-locks fixlafiles news parallel-fetch preserve-libs protect-owned sfperms splitdebug strict unknown-features-warn unmerge-logs unmerge-orphans userfetch" FFLAGS="" GENTOO_MIRRORS="http://distfiles.gentoo.org" LANG="en_US.UTF-8" LDFLAGS="-Wl,-O1" MAKEOPTS="-j9" PKGDIR="/home/paul/gentoo/usr/portage/packages" PORTAGE_CONFIGROOT="/home/paul/gentoo/" PORTAGE_RSYNC_OPTS="--recursive --links --safe-links --perms --times --compress --force --whole-file --delete --stats --timeout=180 --exclude=/distfiles --exclude=/local --exclude=/packages" PORTAGE_TMPDIR="/home/paul/gentoo/var/tmp" PORTDIR="/home/paul/gentoo/usr/portage" PORTDIR_OVERLAY="/home/paul/gentoo/local_ebuilds" SYNC="rsync://rsync.prefix.freens.org/gentoo-portage-prefix" USE="amd64 berkdb blas bzip2 cli cracklib crypt cxx dri fortran gdbm iconv ipv6 mmx modules mudflap ncurses nls nptl nptlonly openmp pcre pdf pppd prefix python readline session sse sse2 ssl sysfs tcpd unicode 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 mmap_emul mulaw multi null plug rate route share shm softvol" APACHE2_MODULES="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 stage tables krita karbon braindump" 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 ubx" INPUT_DEVICES="keyboard mouse evdev" KERNEL="linux" LCD_DEVICES="bayrad cfontz cfontz633 glk hd44780 lb216 lcdm001 mtxorb ncurses text" PHP_TARGETS="php5-3" RUBY_TARGETS="ruby18" USERLAND="GNU" VIDEO_CARDS="fbdev glint intel mach64 mga neomagic nouveau nv r128 radeon savage sis tdfx trident vesa via vmware 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: CPPFLAGS, CTARGET, EMERGE_DEFAULT_OPTS, INSTALL_MASK, LC_ALL, LINGUAS, PORTAGE_BUNZIP2_COMMAND, PORTAGE_COMPRESS, PORTAGE_COMPRESS_FLAGS, PORTAGE_RSYNC_EXTRA_OPTS

We should probably get 3.1.0 in the tree.
(Please note that I have no clue whatsoever about ebuilds, so what I did may contain stupid mistakes.) I took the mpfr-3.1.0 ebuild from the main tree and did three trivial changes. Here is the diff: 3c3 < # $Header: /var/cvsroot/gentoo-x86/dev-libs/mpfr/mpfr-3.1.0.ebuild,v 1.1 2011/10/03 17:43:00 vapier Exp $ --- > # $Header: 19c19 < KEYWORDS="~amd64" --- > KEYWORDS="~ppc-aix ~x64-freebsd ~x86-freebsd ~hppa-hpux ~ia64-hpux ~x86-interix ~amd64-linux ~ia64-linux ~x86-linux ~ppc-macos ~x64-macos ~x86-macos ~m68k-mint ~sparc-solaris ~sparc64-solaris ~x64-solaris ~x86-solaris" 47c47 < --docdir=/usr/share/doc/${PF} \ --- > --docdir=${EPREFIX}/usr/share/doc/${PF} \ 56c56 < pushd "${D}"/usr/share/doc/${PF} >/dev/null --- > pushd "${D}"${EPREFIX}/usr/share/doc/${PF} >/dev/null With this, mpfr emerges just fine (although that pushd looks weird), but the compilation of gcc fails in the configure phase: checking for the correct version of gmp.h... yes checking for the correct version of mpfr.h... yes checking for the correct version of mpc.h... yes checking for the correct version of the gmp/mpfr/mpc libraries... no configure: error: Building GCC requires GMP 4.2+, MPFR 2.3.1+ and MPC 0.8.0+. Said libraries are in ${EPREFIX}/usr/lib so I have no clue about this error.
Hi, Jordi, your modifications are right, just replace "${D}"${EPREFIX} with a shortcut "${ED}". have a look at my updates at bug 391799
Thanks for getting 3.1.0 in the tree and patched up! The configure problem still persists, though. Since this only popped up after the mpfr update, it's most likely libmpfr, but I do not know how to make sure it isn't mpc or gmp that is causing this error.
so, mpfr is now successfully installed, and gcc still claims it cannot find (the right) mpfr/gmp/mpc libs? Are you using Prefix gcc/ld, or are you attempting to build that one?
Exactly. I am using the prefix gcc-4.5.3, which was built against the old mpfr-3.0.1. But 4.5.3 also fails with the same configure error when I try to build it with mpfr-3.1.0.

I am using exactly the same versions gcc-4.5.3-r1 with mpfr-3.1.0, gmp-5.0.2_p1 and mpc-0.9-r1 on many servers, including Fedora Core 3 and 10, Red Hat EL 5.[56], and Centos 4.9, x86-linux and amd64-linux. Let's see what goes wrong.
Also, paste "nm -D ${EPREFIX}/usr/lib/libmpfr.so | grep mpfr_get_z_2exp" please.
maybe we should "wild retreat" on mpfr here, due to bug #390425
The configure error is the one described above. I'll attach the whole build.log. nm -D ${EPREFIX}/usr/lib/libmpfr.so | grep mpfr_get_z_2exp returns 0000000000024ab0 T mpfr_get_z_2exp so the symbol is there.

My impression was that my prefix was a > fairly standard one, but something seems seriously broken. Hmmm, interesting... Just played around at my debian Squeeze box (should be the nearest distro to Ubuntu 10.04) I guess during the configure of mpc, it looked into /usr/include first to get gmp.h and mpfr.h. Just paste 'cpp --verbose' and 'gcc-config -l' and lets see.
(In reply to comment #19) > There is a seemingly related bug out there recently, bug 392655 Hmm... Yeah. I am wondering why mpc caused lots of issues recently. I guess this bug is due to cpp incdir search path, and bug 392655 is due to gcc libdir search path.

Then we will have to look into the config.log and build.log for mpc to figure out where /usr/include/gmp.h comes in. Could you please attach those? HINT ==== In order to get config.log and build.log for mpc, use ebuild instead of emerge (which will delete tmp build files after a success build): ebuild ${EPREFIX}/usr/portage/dev-libs/mpc/mpc-0.9-r1.ebuild compile and get config.log and build.log as usual.
(In reply to comment #22) > /home/paul/gentoo/usr/include just for a quick verification, do you really have /home/paul/gentoo/usr/include/{gmp.h,mpfr.h} ? Another possibility is to emerge gcc-4.2.4 and use it to compile mpc, mpfr and gmp, and then gcc-4.5.3 to see if the problem still exists.
Oh, you are accepting the "~amd64" keyword. Is there a strong reason for that? ebuild with only ~amd64 has not been confirmed to work with prefix yet. Usually we only accept ~amd64-linux.
(and a month old tree, which is years in prefix)

Yes, the header files are there. I'll try the gcc-4.2 route. The ~amd64 keyword was a copy-paste error and I removed it, but I had nothing installed that was not ~amd64-linux anyway.

Hi Jordi, I could find no clue inside the logs. They look quite normal :(

They look quite normal :( I compiled gcc-4.2.4 and used that the rebuild those libraries and gcc-4.5.3 - nothing changed. My situation looks different than the one in bug 392655 , as the prefix paths come before the system paths: LIBRARY_PATH=/home/paul/gentoo/usr/lib/gcc/x86_64-pc-linux-gnu/4.5.3/:/home/paul/gentoo/usr/lib/gcc/x86_64-pc-linux-gnu/4.5.3/../../../../x86_64-pc-linux-gnu/lib/../lib/:/home/paul/gentoo/usr/lib/gcc/x86_64-pc-linux-gnu/4.5.3/../../../../lib/:/lib/../lib64/:/usr/lib/../lib64/:/home/paul/gentoo/usr/lib/gcc/x86_64-pc-linux-gnu/4.5.3/../../../../x86_64-pc-linux-gnu/lib/:/home/paul/gentoo/usr/lib/gcc/x86_64-pc-linux-gnu/4.5.3/../../../:/lib/:/usr/lib/ Could you check if your libmpc is linked to your prefix libmpfr/libgmp?

Can you please try without USE=vanilla? That's supposed to break on Prefix, and a likely cause of this.

Indeed, gcc-4.6.1 now compiles fine, even though libmpc is still linked to the system libmpfr and libgmp, I thought this was the main problem and did not try to compile gcc again after the automatic fortify patches were disabled for host with an old glibc, making USE=vanilla unnecessary. So thanks for all the help!
