Hi all, I have to use GCC 4.0.4 (yes I know it is old, I plan to update to a new version with plugins in the future, but that will take a LOT of work). I recently started using a 64 bit Ubuntu OS instead of 32 bit. However I cant seem to get GCC 4.0.4 to compile on this platform. Basically while compiling I get a link error linking libgcc which is shown below. Does anyone know if it is possible to build this version of GCC for 64 bit Ubuntu? I don't mind patching it a little to get it up and running, but this is the first time I have looked at working with 64 bit platforms and am not familiar with ways around this link problem. Thanks, Brendon. My configure line looked like: ../../dev/gcc-4.0.4/configure -v --enable-languages=c,c++ --prefix=/home/bcosta/build/install --enable-shared --with-system-zlib --without-included-gettext --enable-threads=posix --enable-nls --program-suffix=-4.0 --enable-clocale=gnu --enable-libstdcxx-debug --enable-objc-gc --enable-mpfr --enable-checking=release --build=x86_64-linux-gnu --host=x86_64-linux-gnu --target=x86_64-linux-gnu The link error: mv 'libgcc/32/tmp-libgcc.map' libgcc/32/libgcc.map /home/bcosta/build/gcc-4.0.4/gcc/xgcc -B/home/bcosta/build/gcc-4.0.4/gcc/ -B/home/bcosta/build/install/x86_64-linux-gnu/bin/ -B/home/bcosta/build/install/x86_64-linux-gnu/lib/ -isystem /home/bcosta/build/install/x86_64-linux-gnu/include -isystem /home/bcosta/build/install/x86_64-linux-gnu/sys-include -O2 -DIN_GCC -W -Wall -Wwrite-strings -Wstrict-prototypes -Wmissing-prototypes -Wold-style-definition -isystem ./include -fPIC -g -DHAVE_GTHR_DEFAULT -DIN_LIBGCC2 -D__GCC_FLOAT_NOT_NEEDED -shared -nodefaultlibs -Wl,--soname=libgcc_s.so.1 -Wl,--version-script=libgcc/32/libgcc.map -o 32/libgcc_s.so.1.tmp -m32 libgcc/32/_muldi3_s.o libgcc/32/_negdi2_s.o libgcc/32/_lshrdi3_s.o libgcc/32/_ashldi3_s.o libgcc/32/_ashrdi3_s.o libgcc/32/_cmpdi2_s.o libgcc/32/_ucmpdi2_s.o libgcc/32/_floatdidf_s.o libgcc/32/_floatdisf_s.o libgcc/32/_fixunsdfsi_s.o libgcc/32/_fixunssfsi_s.o libgcc/32/_fixunsdfdi_s.o libgcc/32/_fixdfdi_s.o libgcc/32/_fixunssfdi_s.o libgcc/32/_fixsfdi_s.o libgcc/32/_fixxfdi_s.o libgcc/32/_fixunsxfdi_s.o libgcc/32/_floatdixf_s.o libgcc/32/_fixunsxfsi_s.o libgcc/32/_fixtfdi_s.o libgcc/32/_fixunstfdi_s.o libgcc/32/_floatditf_s.o libgcc/32/_clear_cache_s.o libgcc/32/_enable_execute_stack_s.o libgcc/32/_trampoline_s.o libgcc/32/__main_s.o libgcc/32/_absvsi2_s.o libgcc/32/_absvdi2_s.o libgcc/32/_addvsi3_s.o libgcc/32/_addvdi3_s.o libgcc/32/_subvsi3_s.o libgcc/32/_subvdi3_s.o libgcc/32/_mulvsi3_s.o libgcc/32/_mulvdi3_s.o libgcc/32/_negvsi2_s.o libgcc/32/_negvdi2_s.o libgcc/32/_ctors_s.o libgcc/32/_ffssi2_s.o libgcc/32/_ffsdi2_s.o libgcc/32/_clz_s.o libgcc/32/_clzsi2_s.o libgcc/32/_clzdi2_s.o libgcc/32/_ctzsi2_s.o libgcc/32/_ctzdi2_s.o libgcc/32/_popcount_tab_s.o libgcc/32/_popcountsi2_s.o libgcc/32/_popcountdi2_s.o libgcc/32/_paritysi2_s.o libgcc/32/_paritydi2_s.o libgcc/32/_powisf2_s.o libgcc/32/_powidf2_s.o libgcc/32/_powixf2_s.o libgcc/32/_powitf2_s.o libgcc/32/_mulsc3_s.o libgcc/32/_muldc3_s.o libgcc/32/_mulxc3_s.o libgcc/32/_multc3_s.o libgcc/32/_divsc3_s.o libgcc/32/_divdc3_s.o libgcc/32/_divxc3_s.o libgcc/32/_divtc3_s.o libgcc/32/_divdi3_s.o libgcc/32/_moddi3_s.o libgcc/32/_udivdi3_s.o libgcc/32/_umoddi3_s.o libgcc/32/_udiv_w_sdiv_s.o libgcc/32/_udivmoddi4_s.o libgcc/32/unwind-dw2_s.o libgcc/32/unwind-dw2-fde-glibc_s.o libgcc/32/unwind-sjlj_s.o libgcc/32/gthr-gnat_s.o libgcc/32/unwind-c_s.o -lc && rm -f 32/libgcc_s.so && if [ -f 32/libgcc_s.so.1 ]; then mv -f 32/libgcc_s.so.1 32/libgcc_s.so.1.backup; else true; fi && mv 32/libgcc_s.so.1.tmp 32/libgcc_s.so.1 && ln -s libgcc_s.so.1 32/libgcc_s.so collect2: ld terminated with signal 11 [Segmentation fault] /usr/bin/ld: skipping incompatible /usr/lib/../lib/libc.so when searching for -lc /usr/bin/ld: skipping incompatible /usr/lib/../lib/libc.a when searching for -lc /usr/bin/ld: i386:x86-64 architecture of input file `/usr/lib/../lib/crti.o' is incompatible with i386 output /usr/bin/ld: i386:x86-64 architecture of input file `/usr/lib/../lib/crtn.o' is incompatible with i386 output make[2]: *** [32/libgcc_s.so] Error 1 make[2]: Leaving directory `/home/bcosta/build/gcc-4.0.4/gcc' make[1]: *** [stmp-multilib] Error 2 make[1]: Leaving directory `/home/bcosta/build/gcc-4.0.4/gcc' make: *** [all-gcc] Error 2
