Installation of efibootmgr
At first, fix an outdated hotfix declaration causing compilation failure:
sed -e '/extern int efi_set_verbose/d' -i src/efibootmgr.c
Fix an issue building this package with efivar-38 or later:
sed 's/-Werror//' -i Make.defaults
Build efibootmgr with the following commands:
make EFIDIR=LFS EFI_LOADER=grubx64.efi
This package does not have a test suite.
Now, as the root user:
make install EFIDIR=LFS
Command Explanations
EFIDIR=LFS: This option
specifies the distro's subdirectory name under /boot/efi/EFI. The building system of this
package needs it to be set explicitly.
EFI_LOADER=grubx64.efi:
This option specifies the name of the default EFI boot loader. It
is set to match the EFI boot loader provided by GRUB .
