Bug ID: 57738 Summary: gcc-4.8.1 bootstrap gets unrecognized symbol type "gnu_unique_object" (centos6.4) Product: gcc Version: 4.8.1 Status: UNCONFIRMED Severity: normal Priority: P3 Component: bootstrap Assignee: unassigned at gcc dot gnu.org Reporter: karl at freefriends dot org I'm trying to compile gcc-4.8.1 from the original source on CentOS 6.4 (32-bit). I unpacked gcc and mpc-1.0.1, mpfr-3.1.2, gmp-5.1.2 (the latest released versions of each), made symlinks to the libs, and ran configure from a sibling directory, like this: tar xf gcc-4.8.1.tar.bz2 ... mkdir gccbuild cd gccbuild ../gcc-4.8.1/configure --prefix=/usr/local/gnu --enable-languages=c,c++,objc make bootstrap This went along fine for quite a while, but then aborted with (full command below; it's just whatever gcc's make does): g++ -c -DIN_GCC_FRONTEND -g -DIN_GCC [...] ../../gcc-4.8.1/gcc/cp/except.c /tmp/ccKcKFPk.s: Assembler messages: /tmp/ccKcKFPk.s:7332: Error: unrecognized symbol type "gnu_unique_object" /tmp/ccKcKFPk.s:8051: Error: unrecognized symbol type "gnu_unique_object" make[3]: *** [cp/except.o] Error 1 make[3]: Leaving directory `/u/local/gnu/src/gccb/gcc' Looking at the configure output, I see: checking assembler for gnu_unique_object... no So, on the face of it, it seems that cp/except.c shouldn't be trying to use this feature? FWIW, /usr/bin/as --version on this system (CentOS 6.4, fully patched) says: GNU assembler version 2.20.51.0.2-5.36.el6 20100205 Thanks, Karl For the record, here is the full compile line that failed. g++ -c -DIN_GCC_FRONTEND -g -DIN_GCC -fno-exceptions -fno-rtti -fasynchronou\ s-unwind-tables -W -Wall -Wwrite-strings -Wcast-qual -Wmissing-format-attribute\ -pedantic -Wno-long-long -Wno-variadic-macros -Wno-overlength-strings -fno-com\ mon -DHAVE_CONFIG_H -I. -Icp -I../../gcc-4.8.1/gcc -I../../gcc-4.8.1/gcc/cp -I\ ../../gcc-4.8.1/gcc/../include -I../../gcc-4.8.1/gcc/../libcpp/include -I/usr/l\ ocal/gnu/src/gccb/./gmp -I/usr/local/gnu/src/gcc-4.8.1/gmp -I/usr/local/gnu/src\ /gccb/./mpfr/src -I/usr/local/gnu/src/gcc-4.8.1/mpfr/src -I/usr/local/gnu/src/g\ cc-4.8.1/mpc/src -I../../gcc-4.8.1/gcc/../libdecnumber -I../../gcc-4.8.1/gcc/.\ ./libdecnumber/bid -I../libdecnumber -I../../gcc-4.8.1/gcc/../libbacktrace .\ ./../gcc-4.8.1/gcc/cp/except.c -o cp/except.o
