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.

I had to add this line to the PKGBUILD file:

Compile fixes.
  • sed 's/CFLAGS += -fPIC -Werror -I$(shell ocamlc -where)/CFLAGS += -fPIC -I$(shell ocamlc -where)/' -i tools/ocaml/common.make

@mbroemme First of thanks for getting it working with gcc-9!

Secondly I'm running into the following compile issue: .cache/yay/xen/src/xen-4.12.1/tools/qemu-xen/include/disas/capstone.h:6:10: fatal error: capstone.h: No such file or directory 6 | #include <capstone.h>

I have capstone installed; and /usr/include/capstone/capstone.h exists. Any chance of a suggestion, Also should capstone be listed as a dependency?

mbroemme commented on 2019-08-15 10:08

Package is updated to Xen 4.12.1, ipxe package as well, supporting compilation with gcc-9.

@dhlk thanks for it, added !debug

linuxninja commented on 2019-07-19 07:50

fresh install of arch

attempted to install xen - failed

removed gcc v9, installed gcc-8

symlinked gcc -> gcc-8

re-tried install of xen - failed

/usr/bin/env: 'python': No such file or directory

So, looks like a dependency on python isn't configured properly? python2 is installed...

Installed python (python v3)

re-tried install of xen - failed

ERROR: "cc" either does not exist or does not work

make: Entering directory '/home/user/.cache/yay/xen/src/xen-4.12.0/tools/qemu-xen-build'

make: *** No rule to make target 'all'. Stop.

Not sure how deep this rabbit hole goes. Really don't want to go back to Debian...

"error: taking address of packed member of ..."
Same issue here to build Xen 4.12 w/ kernel 5.1.15, gcc 9.1.0
Solved by downgrading to package gcc8

aiyuchan commented on 2019-06-18 21:14

It seems to not compile at all using the latest GCC (9.1.0, just got out of testing today). I get way too many instances of -Werror=address-of-packed-member.

It's a known bug and afaik has been fixed in xen's git repo for a while now. Might be wise to incorporate the patch into the PKGBUILD until it gets merged into a proper release?

EDIT: I should add that this happens even when adding "--disable-werror" to the config params and "!debug" to the options à la dhlk's commment.

EDIT2: Even the latest, bleeding edge staging versions of xen and ipxe do not compile under GCC 9. I'm sure it'll be fixed in a few days or so, but the official Xen 4.13 release probably won't be coming for a while. If it ends up getting fixed and anyone is interested, I can create a xen-git package.

For anyone else (and my future self) who forgot they enabled debug in makepkg.conf, debug CFLAGS break xen's builds.

Error looks something like this:

<command-line>: error: "__OBJECT_FILE__" redefined [-Werror]
<command-line>: note: this is the location of the previous definition
<command-line>: error: "__OBJECT_LABEL__" redefined [-Werror]
<command-line>: note: this is the location of the previous definition
cc1: all warnings being treated as errors
Makefile:69: recipe for target 'compat/callback.i' failed

Fix requires removing debug in the PKGBUILD:

-options=(!buildflags !strip)
+options=(!buildflags !strip !debug)

Works like a charm, Thank you.
