编译进程适当的费事。并且犯错适当多。搞的我把东西链砍掉重练了好几次～
编译进程：
环境设置:
sudo groupadd armsudo useradd arm -g armsudo passwd arm #设置暗码su - arm #切换帐户export CLFS_HOST="$(echo $MACHTYPE | sed "s/$(echo $MACHTYPE | cut -d- -f2)/cross/")"export CLFS_TARGET="arm-at91-linux"echo export CLFS_HOST=""${CLFS_HOST}"" >> ~/.bashrcecho export CLFS_TARGET=""${CLFS_TARGET}"" >> ~/.bashrc
内核头文件（2.6.35）:
make mrpropermake headers_checkmake INSTALL_HDR_PATH=dest headers_installmkdir -p $CLFS/usr/includecp -rv dest/include/* $CLFS/usr/include
Binutils（2.20）:
mkdir -v ../binutils-buildcd ../binutils-build../binutils-2.20.1/configure --prefix=${CLFS}/cross-tools --host=${CLFS_HOST} --target=${CLFS_TARGET} --with-sysroot=${CLFS} --disable-nls --enable-shared --disable-multilibln -sv /usr/bin/ar $CLFS/cross-tools/bin/${CLFS_HOST)-armake configure-hostmakemake installcp -v ../binutils-2.17/include/libiberty.h ${CLFS}/usr/include
Glibc-Headers(2.11):
tar -xf ../glibc-ports-2.11.tar.bz2mv glibc-ports-2.11 ports #重要，没它就会说the arm is unsupportmkdir -v ../glibc-buildcd ../glibc-buildecho "libc_cv_forced_unwind=yes" > config.cacheecho "libc_cv_c_cleanup=yes" >> config.cacheecho "libc_cv_arm_tls=yes" >> config.cacheecho "libc_cv_arm32_tls=yes" >> config.cacheecho "libc_cv_arm_machine=yes" > config.cacheecho "libc_cv_mlong_double_128=yes" >> config.cacheecho "libc_cv_mlong_double_128ibm=yes" >> config.cacheecho "install_root=${CLFS}" > configparmsCC=gcc ../glibc-2.11/configure --prefix=/usr --host=${CLFS_TARGET} --build=${CLFS_HOST} --with-headers=${CLFS}/usr/include --cache-file=config.cachemake install-headersinstall -dv ${CLFS}/usr/include/bitscp -v bits/stdio_lim.h ${CLFS}/usr/include/bitstouch ${CLFS}/usr/include/gnu/stubs.h

假如一步一步按着这个作的，那么告知你：东西链完成了！
