GRUB-2.12 for EFI

Installation of GRUB-EFI

First, install font data, if you've downloaded it and you've installed the optional dependency FreeType-2.14.1:

mkdir -pv /usr/share/fonts/unifont
zcat ../unifont-17.0.01.pcf.gz > /usr/share/fonts/unifont/unifont.pcf

Warning

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, with low-level operations in the source code which is likely to be broken by some aggressive optimizations.

Add a file missing from the release tarball:

echo depends bli part_gpt > grub-core/extra_deps.lst

Now Prepare GRUB for compilation with the following commands:

./configure --prefix=/usr        \
            --sysconfdir=/etc    \
            --disable-efiemu     \
            --with-platform=efi  \
            --target=x86_64      \
            --disable-werror

Now Compile GRUB with the following commands:

make

This package does not have a test suite providing meaningful results.

Now, if you've skipped the the section called “GRUB-2.12”, install GRUB and skip the remaining instructions in this section:

make install
mv -v /etc/bash_completion.d/grub /usr/share/bash-completion/completions

If you've not skipped the section called “GRUB-2.12”, only install the components not installed:

make -C grub-core install

If you've installed the optional font data and FreeType-2.14.1, install the grub-mkfont program and the font data files (without the font data files GRUB can still function normally, but the boot menu will be displayed using a coarse font or in a smaller region on the screen).

install -vm755 grub-mkfont /usr/bin/
install -vm644 ascii.h widthspec.h *.pf2 /usr/share/grub/

If both Fuse-3.17.4 and LVM2-2.03.36 are installed, also install the grub-mount program:

install -vm755 grub-mount /usr/bin/
