Binutils pass 2

[Michael]

In book we have the follow code for preparing Binutils for compilation

CC="$LFS_TGT-gcc -B/tools/lib/" \
AR=$LFS_TGT-ar RANLIB=$LFS_TGT-ranlib \
../binutils-2.21.1/configure --prefix=/tools \
--disable-nls --with-lib-path=/tools/lib

but at kernel 2.6.22.5 we got error after ran configure script at config.log:

...bla-bla-bla...can't run test application ./a.out
use key --host for cross-compiling
Fatal error

if add key (--host=$LFS_TGT)will fix that problem

CC="$LFS_TGT-gcc -B/tools/lib/" \
AR=$LFS_TGT-ar RANLIB=$LFS_TGT-ranlib \
../binutils-2.21.1/configure --prefix=/tools \
--disable-nls --with-lib-path=/tools/lib --host=$LFS_TGT

sorry, I can't attach file

Here is error in config.log

---

configure:4233: checking whether the C compiler works
configure:4242: ./a.out
FATAL: kernel too old
configure:4246: $?=1
configure:4253: error in '/mnt/lfs/sources/binutils-build':
configure:4257: error: cannot run C compiled programs.
If you meant to cross compile, use '--host'.

The issue is that 'FATAL: kernel too old'. ​http://www.linuxfromscratch.org/lfs/view/7.0/prologue/hostreqs.html mentions that you need a host running at least Linux-2.6.25, but you're running Linux-2.6.22.5.
