Apparently, it is the result of some serious EFI work by the grub
developers.
Dan, I'm looking at upgrading LFS to grub-2.02~beta2. What options do
you use? Right now we have:
./configure --prefix=/usr \
--sbindir=/sbin \
--sysconfdir=/etc \
--disable-grub-emu-usb \
--disable-efiemu \
--disable-werror
We still can't drop the --disable-werror. I get the error:
#warning "_BSD_SOURCE and _SVID_SOURCE are deprecated, use
_DEFAULT_SOURCE" [-Werror=cpp]
I do know that this was fixed upstream. We could either leave in
--disable-werror or sed -i s/BSD/DEFAULT/ grub-core/kern/emu/hostfs.c
What I'm not sure about is the --disable-efiemu switch. Did you need
to enable efiemu?
No I didn't need them. And I think I remember reading in the configure
log that with either --target=x86_64 or --with-platform efi, or both,
efiemu is not available.
Here the options I used:
--prefix=/usr \
--sbindir=/sbin \
--sysconfdir=/etc \
--disable-grub-emu-usb \
--disable-efiemu \
--enable-grub-mkfont \
--enable-device-mapper \
--with-platform=efi \
--target=x86_64 \ [this one and the next one are required for x86_64
and efi
--program-prefix="" \ [really convenient. If not used grub-install
becomes x86_64-grub install]
--with-bootdir="/boot" \
--with-grubdir="grub" \
--disable-werror
I didn't do much experimenting and the group of these is probably
overkill. I don't know anything about emu's and probably didn't need the
usb one. I used mkfont just in case. It depends on freetype2.
What I did learn is that grub won't run in efi if a "suitable graphic"
environment is not found. It depends on having unicode.pf2 available in
/usr/share/grub. I didn't try to build this font with grub but stole it
from my Ubuntu system.
With this in mind, the graphic environment, you will discover that
creating grub.cfg isn't quite as straightforward as it has been. When
you're ready, I'll be more than happy to post my grub.cfg.
Dan
