[libvirt] [PATCH] build: avoid RHEL 5 build failure on LXC

Per the discussion here, LXC on RHEL 5 makes no sense. https://www.redhat.com/archives/libvir-list/2011-September/msg01169.html * configure.ac (with_lxc): Reject RHEL 5.x LXC as too old. --- Pushing under the build-breaker rule. I tested that this has no impact on RHEL 6 or Fedora 14, but that on RHEL 5 it properly skips building the entire lxc driver, letting the build get further (it still died, but on a html file creation error rather than compilation-related). configure.ac | 3 ++- 1 files changed, 2 insertions(+), 1 deletions(-) diff --git a/configure.ac b/configure.ac index 6a0936a..5753c08 100644 --- a/configure.ac +++ b/configure.ac @@ -687,8 +687,9 @@ fi if test "$with_lxc" = "yes" || test "$with_lxc" = "check"; then AC_TRY_LINK([ #include <sched.h> + #include <linux/loop.h> ], [ - unshare (1); + unshare (!LO_FLAGS_AUTOCLEAR); ], [ with_lxc=yes ], [ -- 1.7.4.4
