The GRUB package contains the GRand Unified Bootloader.
GRUB has an issue where it sometimes doesn't detect the disk geometry correctly when used with Linux 2.6. This results in the error message Error 24: Attempt to access block outside partition. The following patch fixes this issue:
patch -Np1 -i ../grub-0.97-disk_geometry-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 \
--host=${LFS_TARGET}
Compile the package:
make
Install the package:
make DESTDIR=${LFS} install
mkdir -v ${LFS}/boot/grub
cp -v ${LFS}/usr/lib/grub/i386-pc/stage{1,2} ${LFS}/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 ${LFS}/boot/grub directory. Most users will copy the e2fs_stage1_5 and/or reiserfs_stage1_5 files.
