We've moved to the newly-stable 4.20.0 branch. There are also other changes:

  • stubdom is fixed by disabling the vtmp and vtpmmgr components. This gets rid of a few source files and our remaining patches.
  • Debug files are only removed if the debug option is not set in makepkg.cfg (or the PKGBUILD itself)
  • pygrub has been removed
  • optdepends are adjusted for the upcoming xen-grub split package for the various Xen flavored builds.

If you're still using pygrub note that it is deprecated. The solution is to build PV grub instead, which used to be in AUR but is now missing. I am asking a couple questions on the mailing list, and I intend to put my current build of xen-grub (which supersedes xen-pvhgrub) on AUR as soon as possible. If you need to build it before that occurs, you can find it in my PKGBUILD repo.

EDIT: 4.20.0-2 adds support for the xen-edk2 package, which has a fixed UEFI for xen

Hello! 4.15.0-3 is here. Here's an update:

1) The current GCC11 patch is updated for 4.15.0 and included here. It was in my github for a bit but I forgot to push it here. Whoops.

2) I've added the recent spate of XSA patches, but one had to be redone for our build environment. It is included.

3) mxca's fixes for EFI have been incorporated, but the directory is set to /boot by default, as I understand this is what is common.

4) On a personal note, my surgery went very well! I am still recovering, but things are looking good for me. Thank you for the well-wishes!

4.15.0-1 doesn't compile. Compilation stops with an error in line 729 of x86_emulate.c because of -Werror=stringop-overflow.

I assume that we see this error due to gcc 11. The command of mxca links to a patch for compiling with gcc 11.

Also, my best wishes go to Refutationalist. I hope the surgery goes well and you can return soon.

I came across this patch to get Xen building with GCC 11.

I also needed to make a few changes to support a system with split /efi and /boot (using XBOOTLDR). I ended up adding the make arguments BOOT_DIR=/boot EFI_DIR=/boot EFI_MOUNTPOINT=/efi. Technically that BOOT_DIR=/boot is redundant because it's the default, but I actually modified the package to set them as variables (e.g., _boot_dir=${boot_dir:-/boot}) and pass "${_common_make_flags[@]} to each make invocation.

EFI_DIR is where the xen.efi symlink farm gets installed along with the actual EFI image, so setting EFI_DIR=/boot looks weird but is the right thing to do on a SystemD bootctl-powered system using XBOOTLDR: the end result is that I don't need a hook to update the EFI system partition.

I also needed to refactor the symlink cleanup; specifically remove all the symlinks at the end after we've done both the multiboot and the EFI image relocations. Otherwise, if BOOT_DIR and EFI_DIR are the same thing you're gonna have a bad time.

I put my changes on github. Built it in a chroot with multilib-build, gonna go test it now.

Update: Works for me.

Thanks for your efforts. I wish you all the best with your surgery and a fast and painless recovery!

1) 4.15.0-1 adds zstd kernel support, so the hook for that is no longer needed, but I'm not sure if ever made it out of my personal repo.

2) The -no-pie problem in linking is present in 4.15, and there's an included patch for that. It is now the only patch needed to compile cleanly on Arch.

3) As promised, stubdom has moved from building by default to not building by default, as no one has spoken up about using it. If I continue maintaining the package, the plan is to remove it in the next major release.

4) I haven't done anything about the SDL2 deps.

5) Unless a co-maintainer is added, this is likely going to be the last release for a few months as I'm going in for surgery to have a brain tumor removed next month.

@juceda must set at top of PKGBUILD

Build Options

_build_stubdom=${build_stubdom:-false} _build_qemu=${build_qemu:-false}

@juceda: how to make the below modification on src/xen-4.14.1/tools/qemu-xen-build/config-host.mak file so that it is taken into account

juceda commented on 2021-02-20 21:48 (UTC)

@Guard - FYI that issue (unable to disambiguate: -no-pie) is caused by a recent binutils package: binutils-2.36-3-x86_64.pkg.tar.zst

If you downgrade it you'll be able to compile again (at least to bypass that point).

the flag is on: src/xen-4.14.1/tools/qemu-xen-build/config-host.mak changing LDFLAGS_NOPIE=-no-pie to LDFLAGS_NOPIE= will also fix the issue.

pkgbuild was successful after changing _build_stubdom and _build_qemu from "build_qemu/stubdom:-true" to "build_qemu/stubdom:-false"

"ld: Error: unable to disambiguate: -no-pie (did you mean --no-pie ?)"

happens every build, regardless of the source. perhaps I am missing a dependency? it fails to build afterwards.
