On x86, with GRUB_PLATFORMS="efi-32 efi-64" or GRUB_PLATFORMS="efi-64", only /usr/lib/grub/i386-efi is built in both cases. beta0 builds both directories for GRUB_PLATFORMS="efi-32 efi-64", as expected (or just /usr/lib/grub/x86_64-efi in the second case). USE-flags: nls.
That was somewhat intentional: I get a configure error when I build grub-2.00_beta0 with GRUB_PLATFORMS=efi-64 on x86. checking whether option -mcmodel=large works... no configure: error: -mcmodel=large not supported. Upgrade your gcc. How did you manage to get it to work?

Well, I just didn't experience any problems building 2.00_beta0 or 1.99-r2 (which I am working with now, since I understand that it's the stable version).

Would you mind attaching those logs? I would really like to figure out if I have something mis-configured in my x86 chroot.

I still didn't figure out how to prevent double compression of attachments -- sorry about that.
Thanks. The following lines are interesting: checking for x86_64-gcc... x86_64-gcc checking for x86_64-objcopy... x86_64-objcopy checking for x86_64-strip... no checking for strip... strip checking for x86_64-nm... x86_64-nm Compare that to mine: checking for x86_64-gcc... no checking for x86_64-egcs... no checking for x86_64-cc... no checking for gcc... gcc checking for x86_64-objcopy... no checking for objcopy... objcopy checking for x86_64-strip... no checking for strip... strip checking for x86_64-nm... no checking for nm... nm Have you set up an x86_64 cross-compiler? That would explain the difference.
(In reply to comment #9) > Have you set up an x86_64 cross-compiler? That would explain the difference. Amazing! Yes, I did -- for the totally unrelated purpose of cross-compiling an x86_64 kernel (ARCH=x86_64 CROSS_COMPILE=x86_64-). ---------- # ls -l /usr/local/bin/x86_64-* lrwxrwxrwx 1 root root 12 Dec 27 02:27 /usr/local/bin/x86_64-ar -> ../../bin/ar -rwxr-xr-x 1 root root 116 Dec 27 02:28 /usr/local/bin/x86_64-gcc lrwxrwxrwx 1 root root 12 Dec 27 02:27 /usr/local/bin/x86_64-ld -> ../../bin/ld lrwxrwxrwx 1 root root 12 Dec 27 02:27 /usr/local/bin/x86_64-nm -> ../../bin/nm lrwxrwxrwx 1 root root 17 Dec 27 02:27 /usr/local/bin/x86_64-objcopy -> ../../bin/objcopy ---------- ---------- # cat /usr/local/bin/x86_64-gcc #!/bin/sh # Emulate x86_64 generic CPU (no corresponding -march switch) exec gcc -m64 -march=nocona -mno-sse3 "$@" ---------- Can something similar be done inside the ebuild?
> Can something similar be done inside the ebuild? I guess that only the x86_64-gcc wrapper is necessary, as x86_64-objcopy and x86_64-nm will fall back to their non-prefixed counterparts, like x86_64-strip did?
I think figured out how to make it work by playing with the TARGET_CC, TARGET_CFLAGS, and TARGET_CPPFLAGS variables. This avoids the need for a wrapper. It seems to work in my chroot. I've committed it to CVS, so it should be available shortly. Please give it a try and let me know if it works for you. + 17 Mar 2012; Mike Gilbert <floppym@gentoo.org> grub-2.00_beta2.ebuild: + Enable building x86_64-efi target on an x86 host. Bug 408545. +
I'm assuming it works.
Hi, I was just waiting for the updates to appear in new portage snapshot. Yes, it does work for me on x86 with GRUB_PLATFORMS="efi-32 efi-64" -- both with the cross-compiling wrappers and without them. By the way, /usr/lib/grub/*/ directories have both .mod and .module files -- I assume that's intended (it doesn't happen with 1.99).
Perhaps the following comparison will also be of interest. grub-1.99-r2: -rw-r--r-- 1 root root 399360 Mar 18 03:40 BOOTIA32.EFI -rw-r--r-- 1 root root 676352 Mar 18 03:40 BOOTx64.EFI grub-2.00_beta2: -rw-r--r-- 1 root root 470528 Mar 18 03:31 BOOTIA32.EFI -rw-r--r-- 1 root root 978432 Mar 18 03:31 BOOTx64.EFI That's quite a difference in size.
I'm not sure why upstream decided to start installing the module files along with the mod files. I made an additional tweak to pass -Os in TARGET_CFLAGS when we set that for efi-64 on x86. That may help reduce the size of your BOOTx64.EFI image.
