приветствую! при сборке gcc под arm926 постоянно валятся ошибки. gcc версии 4.7.1 собирал следующим образом:
./configure --host=arm-none-linux-gnueabi --prefix=/home/arm-lfs/tools --enable-shared --with-gnu-as --with-gnu-ld --disable-multilib --enable-threads=posix --with-arch=armv5te --with-abi=aapcs-linux --with-float=soft --with-mode=arm --enable-__cxa_atexit --enable-target-optspace --disable-bootstrap --enable-languages=c --disable-libada --disable-libssp --disable-libgomp --disable-werror --enable-checking --disable-nls --disable-decimal-float --with-mpfr-include=/home/arm-lfs/tools/include --with-mpfr-lib=/home/arm-lfs/tools/lib --with-mpc-include=/home/arm-lfs/tools/include --with-gmp-include=/home/arm-lfs/tools/include --with-mpc-lib=/home/arm-lfs/tools/lib --with-gmp-lib=/home/arm-lfs/tools/lib
собирал CodeSourcery-2011.03-41.
ошибки такие:
