Jonathan Leban reported an issue to me off-list about his build failing to use qemu because he failed to install yajl-devel. But I recalled specifically tweaking configure.ac to die in that situation (commits 350583c, ba9c38b). After a bit more head-scratching, we found the cause of the regression: commit 654c709 rearranged things so that the qemu version check now occurs before AC_ARG_WITH has had a chance to set either $with_qemu or $with_yajl. Coincidentally, this fix aligns with a documentation patch that was just posted to the autoconf mailing list :) http://thread.gmane.org/gmane.comp.sysutils.autoconf.patches/8324 * m4/virt-lib.m4 (LIBVIRT_CHECK_LIB, LIBVIRT_CHECK_LIB_ALT) (LIBVIRT_CHECK_PKG): Populate defaults earlier. * configure.ac (AC_ARG_WITH): Likewise for drivers.
