[libvirt] [PATCH] build: silence configure warning if ksh is missing
by Eric Blake 26 Oct '10

26 Oct '10

* configure.ac (lv_cv_wrapper_shell): Fix logic error if candidate shell is not available. Reported by Matthias Bolte. --- On IRC, Matthias reported a noisy configure run: eblake: checking for shell that supports <> redirection... ./configure: line 31581: ksh: command not found Worse, if a shell is missing, it doesn't change the contents of conftest.a, so that missing shell would be selected in the loop.

[libvirt] [PATCH] qemu: Fix detection of drive readonly option
by Jiri Denemark 26 Oct '10

26 Oct '10

[libvirt] [PATCH] docs: make the location of the xml catalog file a configure option
by Justin Clift 26 Oct '10

26 Oct '10

The default location for the XML catalog file, /etc/xml/catalog, used when validating the generated html docs, isn't correct for MacOS X. This commit adds an option to the configure script, allowing the default to be overridden: --with-xml-catalog-file=/path/to/xml/catalog/file --- Tested on MacOS X 10.6 (using overridden locatin), and Fedora 13 (using the default location).

[libvirt] [PATCH] Fix build for SystemTap 1.0

With SystemTap 1.0 a part of the generated macros in probes.h expands to: volatile __typeof__(((name))) arg2 = (name); GCC reports an 'invalid initialize' error when name has type char[].
