I have Ubuntu linux and I am trying to install Linux
from scratch (LFS).
I have normal pc with intel 686 cpu.
I have gcc 4.1.2 20060928 (prerelease) 

For this I first have to install binutils.

I follow instructions from page :

So I downloaded the latest binutils in gnu.org
directory. It is version

Then I created binutils-build directory.

Then I run :
configure --prefix=/tools --disable-nls
make install

But it makes so many things that I think this pc
doesnt need :

It creates a huge library file :
-rw-r--r-- 1 lfs lfs  4717022 Jan 21 15:08 libbfd.a

It compiled many stuff like vxwork, which isnt usefull
here I guess.

And I look at config.log,
I get those errors :
configure:2192: checking whether compiler driver
understands Ada
configure:2224: checking how to compare bootstrapped
configure:2344: checking for correct version of gmp.h
configure:2357: gcc -c -g -O2   conftest.c 1>&5
configure:2347:17: error: gmp.h: No such file or
configure: In function 'main':
configure:2351: error: 'choke' undeclared (first use
in this function)
configure:2351: error: (Each undeclared identifier is
reported only onc
configure:2351: error: for each function it appears
configure:2351: error: expected ';' before 'me'
configure: failed program was:
#line 2346 "configure"
#include "confdefs.h"

I think these are minor errors because after that ,
compilation works ok.
But anyway, I write them to you :-).

My aim is to have optimized compilation for the
And I am sure if I followed correct steps and options

Thanks in advance
