Linux From Scratch - Version 7.9

Chapter 6. Installing Basic System Software

6.54. GRUB-2.02~beta2

The GRUB package contains the GRand Unified Bootloader.

Approximate build time: 0.8 SBU
Required disk space: 140 MB

6.54.1. Installation of GRUB

Prepare GRUB for compilation: 

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

The meaning of the new configure options:

--disable-werror

This allows the build to complete with warnings introduced by more recent Flex versions.

--disable-grub-emu-usb --disable-efiemu

These options minimize what is built by disabling features and testing programs not 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”.
