--- Comment #2 from Zhao Jing <zhaojing2 at longcheer dot com> ---
Dear Richard Biener:

I have already installed gmp/mpfr/mpc before install gcc.

zhaojing2@ubuntu:/opt/gcc-4.6.3$ ls gmp-4.3.2/gmp_install/
include  lib  share
zhaojing2@ubuntu:/opt/gcc-4.6.3$ ls mpfr-2.4.2/mpfr_install/
include  lib  share
zhaojing2@ubuntu:/opt/gcc-4.6.3$ ls mpc-0.8.1/mpc_install/
include  lib  share

I suggest you try building gmp/mpfr/mpc in-tree by invoking
./contrib/download_prerequesites prior to build rather than using (possibly
bogus) libs in /opt.
=3D=3D> What's the next step atfer invoking ./contrib/download_prerequesite=
s?
    Could you please describe more details? How can I install the gcc step =
by
step?
    How should I make the configure?

Thanks.=
