C compiler cannot create executables when trying to build Binutils

I am trying to build Linux From Scratch, and now I am at chapter 开发者_Python百科5.4, which tells me how to build Binutils. I have binutils 2.20's source code, but when I try to build it:

time { ./binutils-2.20/configure --target=$LFS_TGT --prefix=/tools --disable-nls --disable-werror ; }

it gives me an error:

checking build system type... i686-pc-linux-gnu

See `config.log' for more details.

I have just installed Ubuntu 10.04, and reinstalled GCC and installed G++. Also, the build is done by a non-root, non-admin user called 'lfs' (which is also described in Linux From Scratch), and on a different partition than where the system is installed.

Can anyone help me? Thanks

The /tools directory didn't exist. I created it and now it compiles fine.

Try:

export CC=/usr/bin/gcc

before running configure.
