The GRUB package contains the GRand Unified Bootloader.

7.12.1. Installation of GRUB

GRUB has an issue where it sometimes doesn't detect the disk geometry correctly when used with Linux 2.6, resulting in the error message Error 24: Attempt to access block outside partition. The following patch contains a fix for this issue as well as various fixes for raid controllers and support for the new Intel Mac:

patch -Np1 -i ../grub-0.97-fixes-1.patch

This package is known to have issues when its default optimization flags (including the -march and -mcpu options) are changed. If any environment variables that override default optimizations have been defined, such as CFLAGS and CXXFLAGS, unset them when building GRUB.

Prepare GRUB for compilation:

./configure --prefix=/usr \
   --build=${CLFS_HOST} --host=${CLFS_TARGET}

Compile the package:

make

Install the package:

make DESTDIR=${CLFS} install
mkdir -v ${CLFS}/boot/grub
cp -v ${CLFS}/usr/lib/grub/*/stage{1,2} ${CLFS}/boot/grub

The i386-pc directory contains a number of *stage1_5 files, different ones for different file systems. Review the files available and copy the appropriate ones to the ${CLFS}/boot/grub directory. Most users will copy the e2fs_stage1_5 and/or reiserfs_stage1_5 files.

Details on this package are located in Section 10.54.2, “Contents of GRUB.”
