[Xen-devel] qemu option

[IAN DELANEY <della5@xxxxxxxxxxxx>]

It appears that the build of qemu and hvm capable options has gone from
optional to obligatory.

From the gentoo ebuild;

.../app-emulation/xen-tools $ ebuild xen-tools-4.3.2.ebuild clean
install

 * Fixing shebang in usr/sbin/xen-ringwatch
 * Fixing shebang in usr/sbin/xenmon.py
>>> Completed installing xen-tools-4.3.2
>>>    into /mnt/gen2/TmpDir/portage/app-emulation/xen-tools-4.3.2/image/

It completes the build without issue.


Then;

.../app-emulation/xen-tools $ ebuild xen-tools-4.4.0.ebuild clean
install

ERROR: pixman not present. Your options:
         (1) Preferred: Install the pixman devel package (any recent
             distro should have packages as Xorg needs pixman too).
         (2) Fetch the pixman submodule, using:
             git submodule update --init pixman

pixman is not installed and the 4.3.2 version builds, then the 4.4.0
release fails on configure in the absence of pixman.

The options are;

1. Install pixman, or
2. Install pixman.

On inquiring @ ##xen, I was more confused when a user informed me his
build also failed, but in the 4.3.2 version, in the absence of an
installed pixman, however all things are not equal since he clearly
uses a different distro.  The configure run is presumably different.

It appears the configure options have sustained some re-writing.  It
appears the build dictates a default selection of a qemu / hvm capable
build.  Is this by accident or intent?

See https://bugs.gentoo.org/show_bug.cgi?id=506072

Thx in anticipation.
