------- Comment #6 from dmarkman at mac dot com 2009-08-28 14:37 ------- thanks for the answer. Here is what I did in the fresh new gcc-4.4.1 folder I issued ./configure --prefix=/home/dmarkman/Development/GCC/macintel64/gcc-4.4.1/build --enable-languages=c,c++ --with-gmp=/home/dmarkman/Development/GCC/macintel64/gmp-4.3.1/build --with-mpfr=/home/dmarkman/Development/GCC/macintel64/mpfr-2.4.1/build -build=x86_64-apple-darwin10.0.0 --host=x86_64-apple-darwin10.0.0 --target=x86_64-apple-darwin10.0.0
and now I got another error: /Volumes/Macintosh_HD/Users/Shared/Development/GCC/gcc-4.4.1/host-x86_64-apple-darwin10.0.0/prev-gcc/xgcc -B/Volumes/Macintosh_HD/Users/Shared/Development/GCC/gcc-4.4.1/host-x86_64-apple-darwin10.0.0/prev-gcc/ -B/home/dmarkman/Development/GCC/macintel64/gcc-4.4.1/build/x86_64-apple-darwin10.0.0/bin/ -g -O2 -DIN_GCC -W -Wall -Wwrite-strings -Wstrict-prototypes -Wmissing-prototypes -Wcast-qual -Wold-style-definition -Wc++-compat -Wmissing-format-attribute -pedantic -Wno-long-long -Wno-variadic-macros -Wno-overlength-strings -DHAVE_CONFIG_H -o cc1plus-dummy \ cp/cp-lang.o stub-objc.o cp/call.o cp/decl.o cp/expr.o cp/pt.o cp/typeck2.o cp/class.o cp/decl2.o cp/error.o cp/lex.o cp/parser.o cp/ptree.o cp/rtti.o cp/typeck.o cp/cvt.o cp/except.o cp/friend.o cp/init.o cp/method.o cp/search.o cp/semantics.o cp/tree.o cp/repo.o cp/dump.o cp/optimize.o cp/mangle.o cp/cp-objcp-common.o cp/name-lookup.o cp/cxx-pretty-print.o cp/cp-gimplify.o tree-mudflap.o attribs.o c-common.o c-format.o c-pragma.o c-semantics.o c-lex.o c-dump.o i386-c.o darwin-c.o c-pretty-print.o c-opts.o c-pch.o incpath.o cppdefault.o c-ppoutput.o c-cppbuiltin.o prefix.o c-gimplify.o c-omp.o tree-inline.o dummy-checksum.o main.o libbackend.a ../libcpp/libcpp.a ../libdecnumber/libdecnumber.a ../libcpp/libcpp.a ./../intl/libintl.a -liconv ../libiberty/libiberty.a ../libdecnumber/libdecnumber.a -L/home/dmarkman/Development/GCC/macintel64/gmp-4.3.1/build/lib -L/home/dmarkman/Development/GCC/macintel64/mpfr-2.4.1/build/lib -lmpfr -lgmp ld: duplicate symbol _init_inline_once in libbackend.a(tree-inline.o) and tree-inline.o collect2: ld returned 1 exit status make[3]: *** [cc1plus-dummy] Error 1 make[2]: *** [all-stage2-gcc] Error 2 make[1]: *** [stage2-bubble] Error 2 make: *** [all] Error 2 and BTW, from the gcc-4.4.1 I called command: find . -name *.o | xargs file and I saw that majority of the .o files have x86_64 arch., but there are .o file with i386 (especially from prev-gcc/i386 and i386/libgcc folders) also I did try to build gcc with x86_64 kernel, unfortunately config.guess doesn't guess right, because uname -p still returns i386 only uname -m returns x86_64 I found that very confusing command arch also returns i386 and now I can say that building gcc on x86_64 kernel machine gave me the same duplication error thanks in advance -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=41180
