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

Details are here:

I am getting this error when trying to compile:

@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.

dhlk commented on 2019-03-02 21:09

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.
