Error cross-compiling glibc, chapter 5

At "make AUTOCONF=no" for Glibc-2.3.3, in Chapter 5, LFS 5.1.1, i get the error:

Code:

In file included from ../include/libc-symbols.h:56,
                 from <command line>:6:
/mnt/lfs/sources/glibc-build/config.h:3:3: #error "glibc cannot be compiled without optimization"
make[2]: *** [/mnt/lfs/sources/glibc-build/tcb-offsets.h] Error 1

make[1]: Leaving directory `/mnt/lfs/sources/glibc-2.3.3-lfs-5.1'
make: *** [all] Error 2
lfs:/mnt/lfs/sources/glibc-build$

Im following the book, apart from using the cross-compiling hint (http://archive.daniel-baumann.ch/lin...-x86-5.1-1.txt)

The output of env is:

Code:

TERM=xterm
LC_ALL=POSIX
LFS=/mnt/lfs
CXXFLAGS=-march=pentium
PATH=/tools/bin:/bin:/usr/bin
CHOST=i586-pc-linux-gnu
PWD=/mnt/lfs/sources/glibc-build
PS1=\u:\w\$
SHLVL=1
HOME=/home/lfs
CFLAGS=-march=pentium
_=/usr/bin/env
OLDPWD=/mnt/lfs/sources

To configure i used the options as specified in the crosscompiling hint.

How do i cross-compile glibc?

Thanks.

This isn't quite cross-compiling as such, more fooling the build into thinking you are running
on a different processor type (assuming you are using the kernel module).

One thing to note, according to the hint you set CHOST to be your target cpu type
( ie export CHOST="i386" ), not the full target triplet.

For true cross-compilation there are proof-of-concept scripts available under my homedir
for the adventurous, but these aren't for the faint of heart
( http://www.linuxfromscratch.org/~ryan/scripts/cross-lfs )
