Two regressions:
Commit df1011ca broke builds for systems that lack devmapper
(non-Linux, as well as Linux with ./autogen.sh --without-libvirtd
and without the libraries present).
Commit ce6fd650 broke cross-compilation, due to a gnulib bug.
* .gnulib: Update to latest, for cross-compilation fix.
* src/util/util.c (virIsDevMapperDevice): Provide stub for
platforms not using storage driver.
* configure.ac (devmapper): Arrange to define HAVE_LIBDEVMAPPER_H.
devmapper issue reported by Wen Congyang.
---
Thankfully, neither regression was in the 0.8.7 release.
Pushing this under the build-breaker rule, as verified by
./autobuild.sh.
* .gnulib aa0f5d7...17adb5d (9):
> longlong: skip, rather than fail, on cross-compilation
> * NEWS: Mention 2011-02-08 change to stdlib.
> getloadavg: Add comments about platforms.
> getloadavg: Fix link error on Solaris 2.6.
> * lib/getloadavg.c (getloadavg) [sgi]: Make ldav_off of type ptrdiff_t.
> Oops, fix syntax error in last config.rpath commit.
> havelib: Fix comments.
> havelib: Update config.rpath.
> getloadavg test: Add some plausibility checks.
