Linux From Scratch - Version 7.0-rc1

Chapter 6. Installing Basic System Software

6.46. GRUB-1.99

The GRUB package contains the GRand Unified Bootloader.

Approximate build time: 0.6 SBU
Required disk space: 76 MB

6.46.1. Installation of GRUB

Prepare GRUB for compilation: 

./configure --prefix=/usr           \
             --sysconfdir=/etc      \
             --disable-grub-emu-usb \
             --disable-efiemu       \
             --disable-werror

The --disable switches minimize what is built by disabling features and testing programs not really needed for LFS.

Compile the package: 

make

This package does not come with a test suite.

Install the package: 

make install

Using GRUB to make your LFS system bootable will be discussed in Section 8.4, “Using GRUB to Set Up the Boot Process”.
