Build a complete Linux system from LFS official documentation

This article is not a beginner Tutorial!!!

• Parallels Desktop (to prevent the NIC type from being found to be set to Intel (R) pro/1000 MT).
• KALI-LINUX-2.0-AMD64 (i386). ISO (the LIVECD compilation tool is complete, LiveCD start another installation bison, gawk, directly apt-get install can be installed).
• Other virtual machine hardware is set by personal requirements.
• Tool detection required by the host system

• Build method follow the official documentation step-by-step, just copy and paste. Here are some things to watch out for. (After you build tools, enter Chroot)

When you compile and install GCC, you do not check, but you must perform

1 install-v-dm755/usr/lib/bfd-plugins 2 3 ln-sfv. /.. /libexec/gcc/$ (gcc-dumpmachine)/5.2.0/liblto_plugin.so/usr/lib/bfd-plugins/

Otherwise, the problem of the class library and header file cannot be found when the software is subsequently compiled. If you are not at ease, every time you install a software ldconfig a bit.

• After installing the software (before compiling the kernel and installing grub), you can configure the relevant files without following the documentation method. Install the following method to configure the basic system required files, to meet the basic operation of the system, and network connection.

• Logout remember to set the root password passwd before you go to the host system.

For subsequent installation of the software and ease of use, it is recommended to install OpenSSH, OpenSSL and wget according to the Blfs documentation. As for SSH configuration, you can install the following methods to resolve root login and permissions issues

1 vim/etc/ssh/passwordauthentication yes4 permitrootlogin Yes
