Building and Installing GCC

2 questions on the same day... I'm not doin' to hot. Here's the problem: In section 5.5.1, I'm supposed to install GCC to do this I have to unarchive the GMP and MPFR packages. I've done this. They're in the build directory (gcc-build) with GCC however, when I run the script to prepare for compilation,

CC="gcc -B/usr/bin/" ../gcc-4.3.2/configure --prefix=/tools \
--with-local-prefix=/tools --disable-nls --disable-shared --disable-libssp \
--enable-languages=c

I'm told that I need to include GMP 4.2.0+ and MPFR 2.3.0+. What am I doing wrong?
(Here's the URL to the section of the book if you need to look at that: http://www.linuxfromscratch.org/lfs/...gcc-pass1.html)

LFS 6.4 , § 5.5.1

As you can see, the build directory is made
after you unpack mpfr and gmp.

The starting point for building the (most ?) software in Linux :
Example, gcc
1) tar xvf gcc-4.3.2.tar.bz2
2) cd gcc-4.3.2/
So that is your location, when told to unpack mpfr + gmp.
( Hence the command 'mkdir -v ../gcc-build', which would
be wrong, if your current location wasn't inside gcc-4.3.2/ )

Summary : mpfr, gmp are unpacked into gcc-4.3.2/ , and
you can just move it there, or start from scratch.

Okay, thanks, I'll move them and try it.
