GRUB On ARM64 systems, the following instruction builds GRUB for UEFI. But the built GRUB lacks some features because a few optional dependencies of GRUB for UEFI is beyond the scope of LFS and not installed yet. If your system firmware does not support UEFI, you need to skip the content of this page and try to figure out how to boot your system. If your system has UEFI support and you wish to boot LFS with UEFI, you can skip this package in LFS, and install GRUB with UEFI support (and its dependencies) by following the instructions on the BLFS page (with --target=x86_64 removed). Unset any environment variables which may affect the build: unset {C,CPP,CXX,LD}FLAGS Don't try tuning this package with custom compilation flags. This package is a bootloader. The low-level operations in the source code may be broken by aggressive optimization. Fix an issue causing grub-install to fail when the /boot partition (or the root partition if /boot is not a separate partition) is created by e2fsprogs-1.47.0 or later: patch -Np1 -i ../grub-&grub-version;-upstream_fixes-1.patch Apply an upstream change so GRUB will be capable to load compressed kernel image on an ARM64 system: sed '/ARMXX_MAGIC/,+2d' -i grub-core/loader/arm64/linux.c Prepare GRUB for compilation: ./configure --prefix=/usr \ --sysconfdir=/etc \ --disable-efiemu \ --disable-werror --disable-werror This allows the build to complete with warnings introduced by more recent versions of Flex. --disable-efiemu This option minimizes what is built by disabling a feature and eliminating some test programs not needed for LFS. Compile the package: make The test suite for this packages is not recommended. Most of the tests depend on packages that are not available in the limited LFS environment. To run the tests anyway, run make check. Install the package: make install mv -v /etc/bash_completion.d/grub /usr/share/bash-completion/completions Making your LFS system bootable with GRUB will be discussed in .
