建立自己的linux系统(二)

    从现在开始一直到第五章结束,也就是完成Stripping中间的步骤中如果重新启动的恢复步骤:
  1.重新启动计算机,并从LiveCD启动
  相关知识点:在VMWare中因为磁盘已经有了信息了,所以会从磁盘启动,需要在启动虚拟机中的机器时按F2进入虚拟机的虚拟BIOS,然后在BOOT中设置第一启动为CD-ROM,保存退出即可。


        2.LiveCD启动过程同第一次启动选择一样。
  3.加载分区
  export LFS=/mnt/lfs
  mkdir -pv $LFS
  mount /dev/hda2 $LFS
  4.加载交换分区(如果不想用交换分区或者没有交换分区可跳过此步骤)
  swapon /dev/hda1
  5.建立工具链的链接
  ln -sv $LFS/tools /
  6.创建lfs用户
  groupadd lfs
  useradd -s /bin/bash -g lfs -m -k /dev/null lfs
  passwd lfs
  chown -v lfs $LFS/tools
  chown -v lfs $LFS/sources
  su - lfs
  7.建立lfs用户的环境
  cat > ~/.bash_profile << "EOF"
  exec env -i HOME=$HOME TERM=$TERM PS1='\u:\w\$ ' /bin/bash
  EOF
  cat > ~/.bashrc << "EOF"
  set +h
  umask 022
  LFS=/mnt/lfs
  LC_ALL=POSIX
  PATH=/tools/bin:/bin:/usr/bin
  export LFS LC_ALL PATH
  EOF
  source ~/.bash_profile
  8.检查一下
  export命令查看输出,应该是
  declare -x HOME="/home/lfs"
  declare -x LC_ALL="POSIX"
  declare -x LFS="/mnt/lfs"
  declare -x OLDPWD
  declare -x PATH="/tools/bin:/bin:/usr/bin"
  declare -x PS1="\\u:\\w\\\$ "
  declare -x PWD="/home/lfs"
  declare -x SHLVL="1"
  declare -x TERM="linux"
  9.进入编译目录
  cd $LFS/sources
  基本上就恢复工作状态了。

开始工具链的制作
进入LFS包编译目录
cd $LFS/sources

tar xvf /lfs-sources/binutils-2.17.tar.bz2 cd binutils-2.17
相关知识点:
  大家可以注意到后面所有的解包命令均使用tar xvf来完成,而不管文件的压缩方式是bz2还是gz,这是因为较新的tar程序都具有自动识别后缀名并自动调用相应的解压缩工具的能力,所以可以不需要指定压缩方式,但对于早期的tar命令则可能不具备这个功能因此需要你根据包的压缩方式来指定,如bz2使用j,gz使用z,对应上面的binutils 则是tar xvjf /lfs-sources/binutils-2.17.tar.bz2
  因LFS的LiveCD中提供的tar版本比较新,后面制作的tar版本也比较新,因此支持自动识别的能力,同时为了使文章的解压命令看起来比较统一方便维护(同样对于想制作成脚本的朋友也会比较方便)因此后面统一使用tar xvf来解压。

  接着我们需要建立一个目录,因为binutils建议使用一个空目录来编译
mkdir -v ../binutils-build cd ../binutils-build CC="gcc -B/usr/bin/" ../binutils-2.17/configure --prefix=/tools --disable-nls --disable-werror make make install make -C ld clean make -C ld LIB_PATH=/tools/lib cp -v ld/ld-new /tools/bin cd .. rm -rf binutils-build rm -rf binutils-2.17
tar xvf /lfs-sources/gcc-4.1.2.tar.bz2 mkdir -v gcc-build cd gcc-build CC="gcc -B/usr/bin/" ../gcc-4.1.2/configure --prefix=/tools \ --with-local-prefix=/tools --disable-nls \ --enable-shared --enable-languages=c make bootstrap make install ln -vs gcc /tools/bin/cc cd .. rm -rf gcc-build rm -rf gcc-4.1.2

Linux-2.6.22.5 API Headers
tar xvf /lfs-sources/linux-2.6.22.5.tar.bz2 cd linux-2.6.22.5 make mrproper make headers_check make INSTALL_HDR_PATH=dest headers_install cp -rv dest/include/* /tools/include cd .. rm -rf linux-2.6.22.5

Glibc-2.5.1
tar xvf /lfs-sources/glibc-2.5.1.tar.bz2 cd glibc-2.5.1 mkdir -v ../glibc-build cd ../glibc-build ../glibc-2.5.1/configure --prefix=/tools \ --disable-profile --enable-add-ons \ --enable-kernel=2.6.0 --with-binutils=/tools/bin \ --without-gd --with-headers=/tools/include \ --without-selinux make mkdir -v /tools/etc touch /tools/etc/ld.so.conf make install cd .. rm -rf glibc-build rm -rf glibc-2.5.1

相关知识点:
  这里的参数--enable-kernel=2.6.0,只是为了说明kernel的大版本,所以不需要根据实际的kernel版本来改,即使是用linux-2.6.15也一样只写2.6.0就可以了。

调整工具链
mv -v /tools/bin/{ld,ld-old} mv -v /tools/$(gcc -dumpmachine)/bin/{ld,ld-old} mv -v /tools/bin/{ld-new,ld} ln -sv /tools/bin/ld /tools/$(gcc -dumpmachine)/bin/ld gcc -dumpspecs | sed 's@^/lib/ld-linux.so.2@/tools&@g' > `dirname $(gcc -print-libgcc-file-name)`/specs GCC_INCLUDEDIR=`dirname $(gcc -print-libgcc-file-name)`/include && find ${GCC_INCLUDEDIR}/* -maxdepth 0 -xtype d -exec rm -rvf '{}' \; && rm -vf `grep -l "DO NOT EDIT THIS FILE" ${GCC_INCLUDEDIR}/*` && unset GCC_INCLUDEDIR

相关知识点:
  工具链的调整方法有好几种,而且不同版本GCC的specs可能会有不同,但实际上都是把specs文件中的/lib/ld-linux.so.2替换成了/tools/lib/ld-linux.so.2,所以即使有些文章在调整工具链上的命令和LFS手册上的不一样也不用太奇怪,当然也可以直接用gcc -dumpspecs导出后手工直接编辑specs文件。

测试工具链的调整
echo 'main(){}' > dummy.c
cc dummy.c
readelf -l a.out | grep 'tools'
如果输出大致如下
[Requesting program interpreter: /tools/lib/ld-linux.so.2]
则表示调整成功,因为所有的库已经连接到了/tools/lib下。
rm -rf a.out dummy.c

测试工具安装
说明:这部分将安装3个用于第六章各种源码包编译后的测试的工具,所以如果你不打算做make check之类的事情,那么这3个包可以不装。
Tcl-8.4.15 Expect-5.43.0 DejaGNU-1.4.4
tar xvf /lfs-sources/tcl8.4.15-src.tar.gz cd tcl8.4.15/unix ./configure --prefix=/tools make make install make install-private-headers ln -sv tclsh8.4 /tools/bin/tclsh cd $LFS/sources tar xvf /lfs-sources/expect-5.43.0.tar.gz cd expect-5.43 patch -Np1 -i /lfs-sources/expect-5.43.0-spawn-1.patch cp configure{,.bak} sed 's:/usr/local/bin:/bin:' configure.bak > configure ./configure --prefix=/tools --with-tcl=/tools/lib --with-tclinclude=/tools/include --with-x=no make make SCRIPTS="" install cd $LFS/sources tar xvf /lfs-sources/dejagnu-1.4.4.tar.gz cd dejagnu-1.4.4 ./configure --prefix=/tools make install cd .. rm -rf tcl8.4.15 rm -rf expect-5.43 rm -rf dejagnu-1.4.4

tar xvf /lfs-sources/gcc-4.1.2.tar.bz2 cd gcc-4.1.2 cp -v gcc/Makefile.in{,.orig} sed 's@\./fixinc\.sh@-c true@' gcc/Makefile.in.orig > gcc/Makefile.in cp -v gcc/Makefile.in{,.tmp} sed 's/^XCFLAGS =$/& -fomit-frame-pointer/' gcc/Makefile.in.tmp \ > gcc/Makefile.in patch -Np1 -i /lfs-sources/gcc-4.1.2-specs-1.patch mkdir -v ../gcc-build cd ../gcc-build ../gcc-4.1.2/configure --prefix=/tools \ --with-local-prefix=/tools \ --enable-clocale=gnu --enable-shared \ --enable-threads=posix --enable-__cxa_atexit \ --enable-languages=c,c++ --disable-libstdcxx-pch make make install cd .. rm -rf gcc-build rm -rf gcc-4.1.2

再次测试工具链的调整,以确保刚刚编译的gcc正确工作
echo 'main(){}' > dummy.c
cc dummy.c
readelf -l a.out | grep 'tools'
如果输出大致如下
[Requesting program interpreter: /tools/lib/ld-linux.so.2]
则表示调整成功,因为所有的库已经连接到了/tools/lib下。
rm -rf a.out dummy.c

tar xvf /lfs-sources/binutils-2.17.tar.bz2 mkdir -v binutils-build cd binutils-build ../binutils-2.17/configure --prefix=/tools --disable-nls \ --with-lib-path=/tools/lib make make install make -C ld clean make -C ld LIB_PATH=/usr/lib:/lib cp -v ld/ld-new /tools/bin cd .. rm -rf binutils-build rm -rf binutils-2.17

Texinfo-4.9
tar xvf /lfs-sources/texinfo-4.9.tar.bz2 cd texinfo-4.9 ./configure --prefix=/tools make make install cd .. rm -rf texinfo-4.9

tar xvf /lfs-sources/util-linux-2.12r.tar.bz2 cd util-linux-2.12r sed -i 's@/usr/include@/tools/include@g' configure ./configure make -C lib make -C mount mount umount make -C text-utils more cp -v mount/{,u}mount text-utils/more /tools/bin cd .. rm -rf util-linux-2.12r

Stripping
这步是可有可无的,如果你打算今后还要用/tools里面的东西,那么可以strip一下来减少占用的磁盘空间,但如果做完目标系统后就删除了,不Strip也可以,反正最后也是要删掉的。
strip --strip-debug /tools/lib/* strip --strip-unneeded /tools/{,s}bin/*

info和man里面的内容在制作过程中没什么用处,所以删掉
rm -rf /tools/{info,man}

退出lfs用户
exit

到目前为止,工具链已经制作完成了,接着就要开始制作真正的目标系统了,如果你到目前为止没出什么问题,那么恭喜你成功的通过了一关,不过接着还有相当长的路。

从现在开始不在需要lfs用户来制作系统了
chown -R root:root $LFS/tools
