Toolchain

• GCC compiler, Binutils, and Glibc.

Basic System:

• Linux kernel
• Coreutils (basic file, shell, and text utilities)
• Bash shell
• GCC (GNU Compiler Collection)
• Binutils (binary tools like the assembler and linker)

LFS for beginners

LFS Source Download

1. Source Code
   In Linux From Scratch, you’ll compile everything from source code. This means you’ll be downloading raw code files and compiling them into binaries that your system can run.
   Understanding how to use compilers like GCC (GNU Compiler Collection) will be essential.

2. Toolchain
   A toolchain is a collection of programming tools used to develop a software project.
   In LFS, you’ll be building a temporary toolchain (consisting of compilers, linkers, and libraries) that will be used to compile the rest of the system.

3. Bootloader
   The bootloader is the first software that runs when your computer starts up.
   In LFS, you’ll need to install and configure a bootloader (like GRUB) to ensure your system can boot into the operating system you’ve built.

4. Kernel
   The Linux kernel is the core of the operating system, managing hardware resources and enabling communication between hardware and software.
   In LFS, you’ll download and compile the kernel yourself.

5. File Systems
   LFS requires a solid understanding of Linux file systems, such as ext4. You’ll need to format partitions, create a root file system, and set up the necessary directories for your system.
