This is on an old Sun Sparc machine running Solaris 8. I had CFLAGS set thus :
$ echo $CFLAGS -mcpu=v7 -m32 -mno-app-regs -pthreads I was using gcc version 4.2.4 to perform this bootstrap and I set the configure options for non-GNU as and ld thus : $ ../gcc-4.3.3/configure --with-as=/usr/ccs/bin/as \ > --without-gnu-ld --with-ld=/usr/ccs/bin/ld --with-cpu=v7 \ > --enable-threads=posix --disable-nls --prefix=/export/home/dclarke/local \ > --with-local-prefix=/export/home/dclarke/local --enable-shared \ > --enable-languages=c,c++,objc,fortran \ > --with-gmp=/export/home/dclarke/local \ > --with-mpfr=/export/home/dclarke/local \ > --enable-bootstrap Phase one of the boot strap results in this : $ /export/nfs/build/gnu/GCC/gcc-4.3.3-build/gcc/xgcc -v Using built-in specs. Target: sparc-sun-solaris2.8 Configured with: ../gcc-4.3.3/configure --with-as=/usr/ccs/bin/as --without-gnu-ld --with-ld=/usr/ccs/bin/ld --with-cpu=v7 --enable-threads=posix --disable-nls --prefix=/export/home/dclarke/local --with-local-prefix=/export/home/dclarke/local --enable-shared --enable-languages=c,c++,objc,fortran --with-gmp=/export/home/dclarke/local --with-mpfr=/export/home/dclarke/local --enable-bootstrap Thread model: posix gcc version 4.3.3 (GCC) Shortly into what looks like phase 2 I see the process fails thus : /export/nfs/build/gnu/GCC/gcc-4.3.3-build/./gcc/xgcc -B/export/nfs/build/gnu/GCC/gcc-4.3.3-build/./gcc/ -B/export/home/dclarke/local/sparc-sun-solaris2.8/bin/ -B/export/home/dclarke/local/sparc-sun-solaris2.8/lib/ -isystem /export/home/dclarke/local/sparc-sun-solaris2.8/include -isystem /export/home/dclarke/local/sparc-sun-solaris2.8/sys-include -g -fkeep-inline-functions -m64 -O2 -O2 -g -mcpu=v7 -m32 -mno-app-regs -pthreads -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 -I. -I. -I../../.././gcc -I../../../../gcc-4.3.3/libgcc -I../../../../gcc-4.3.3/libgcc/. -I../../../../gcc-4.3.3/libgcc/../gcc -I../../../../gcc-4.3.3/libgcc/../include -DHAVE_CC_TLS -o _muldi3.o -MT _muldi3.o -MD -MP -MF _muldi3.dep -DL_muldi3 -c ../../../../gcc-4.3.3/libgcc/../gcc/libgcc2.c \ xgcc: may not use both -m32 and -m64 make[5]: *** [_muldi3.o] Error 1 make[5]: Leaving directory `/export/nfs/build/gnu/GCC/gcc-4.3.3-build/sparc-sun-solaris2.8/sparcv9/libgcc' make[4]: *** [multi-do] Error 1 make[4]: Leaving directory `/export/nfs/build/gnu/GCC/gcc-4.3.3-build/sparc-sun-solaris2.8/libgcc' make[3]: *** [all-multi] Error 2 make[3]: Leaving directory `/export/nfs/build/gnu/GCC/gcc-4.3.3-build/sparc-sun-solaris2.8/libgcc' make[2]: *** [all-stage1-target-libgcc] Error 2 make[2]: Leaving directory `/export/nfs/build/gnu/GCC/gcc-4.3.3-build' make[1]: *** [stage1-bubble] Error 2 make[1]: Leaving directory `/export/nfs/build/gnu/GCC/gcc-4.3.3-build' make: *** [all] Error 2 I do not know why the option -m64 is in there.
