做9260的交叉工具遇到的问题

编译过程相当的麻烦。而且出错相当多。搞的我把工具链砍掉重练了好几次~

编译过程:

环境设置:

sudo groupadd arm
sudo useradd arm -g arm
sudo passwd arm #设置密码
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}\"" >> ~/.bashrc
echo export CLFS_TARGET=\""${CLFS_TARGET}\"" >> ~/.bashrc

内核头文件(2.6.35):

make mrproper
make headers_check
make INSTALL_HDR_PATH=dest headers_install
mkdir -p $CLFS/usr/include
cp -rv dest/include/* $CLFS/usr/include

Binutils(2.20):

mkdir -v ../binutils-build
cd ../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-multilib
ln -sv /usr/bin/ar $CLFS/cross-tools/bin/${CLFS_HOST)-ar
make configure-host
make
make install
cp -v ../binutils-2.17/include/libiberty.h ${CLFS}/usr/include

Glibc-Headers(2.11):

tar -xf ../glibc-ports-2.11.tar.bz2
mv glibc-ports-2.11 ports #重要,没它就会说the arm is unsupport
mkdir -v ../glibc-build
cd ../glibc-build
echo "libc_cv_forced_unwind=yes" > config.cache
echo "libc_cv_c_cleanup=yes" >> config.cache
echo "libc_cv_arm_tls=yes" >> config.cache
echo "libc_cv_arm32_tls=yes" >> config.cache
echo "libc_cv_arm_machine=yes" > config.cache
echo "libc_cv_mlong_double_128=yes" >> config.cache
echo "libc_cv_mlong_double_128ibm=yes" >> config.cache
echo "install_root=${CLFS}" > configparms
CC=gcc ../glibc-2.11/configure --prefix=/usr \
--host=${CLFS_TARGET} --build=${CLFS_HOST} \
--with-headers=${CLFS}/usr/include --cache-file=config.cache
make install-headers
install -dv ${CLFS}/usr/include/bits
cp -v bits/stdio_lim.h ${CLFS}/usr/include/bits
touch ${CLFS}/usr/include/gnu/stubs.h

Gcc-4.5.1 Pass1:

GCC-Pass3

patch -Np1 -i ../gcc-4.5.1-startfiles_fix-1.patch
tar -xf ../gmp-5.0.1.tar.bz2
tar -xf ../mpc-0.8.2.tar.gz
tar -xf ../mpfr-3.0.0.tar.bz2

--enable-languages=c,c++ --enable-__cxa_atexit \
--enable-c99 --enable-long-long --enable-threads=posix
make all-gcc
make install-gcc #重要!
make
make install
ln -vs libgcc.a `$LFS_TGT-gcc -print-libgcc-file-name | \
    sed 's/libgcc/&_eh/'` #相当重要,没有这个符号连接就别想编译glibc

如果一步一步按着这个作的,那么告诉你:工具链完成了!
