[Clfs-dev] problems cross compiling gcc

[Luís Vitório Cargnini]

well according to the book
http://cross-lfs.org/view/clfs-sysroot/arm/cross-tools/binutils.html:
this is the result after make:
          && mv BLD-POTFILES-t BLD-POTFILES )
cd .. \
          && CONFIG_FILES=po/Makefile.in:po/Make-in \
             CONFIG_HEADERS= /bin/sh ./config.status
config.status: creating po/Makefile.in
config.status: executing depfiles commands
config.status: executing libtool commands
config.status: executing default-1 commands

how to fix this ?
this was  I tried the  binutils 2.17 instead of 2.18
