Trying to enable automake's subdir-objects option resulted in the creation of literal directories such as src/$(srcdir)/remote/. I traced this to the fact that we had used a literal $(srcdir) in a location that later fed an automake *_SOURCES variable. This has also been reported as an automake bug: http://debbugs.gnu.org/cgi/bugreport.cgi?bug=13928 but it's better to fix our code than to wait for an automake fix. Some things to remember that affect VPATH builds, and where an in-tree build is blissfully unaware of the issues: if a VPATH build fails to find a file that was used as a prereq of any other target, then the rule for that file will expand $@ to prefer the current build dir (bad because a VPATH build on a fresh checkout will then stick $@ in the current directory instead of the desired srcdir); conversely, if a VPATH build finds the file in srcdir but decides it needs to be rebuilt, then the rule for that file will expand $@ to include the directory where it was found out-of-date (bad for an explicit listing of $(srcdir)/$@ because an incremental VPATH build will then expand srcdir twice). As we want these files to go into srcdir unconditionally, we have to massage or avoid $@ for any recipe that involves one of these files. Therefore, this patch removes all uses of $(srcdir) from any generated file name that later feeds a *_SOURCES variable, and then rewrites all the recipes to generate those files to hard-code their creation into srcdir without the use of $@. * src/Makefile.am (REMOTE_DRIVER_GENERATED): Drop $(srcdir); VPATH builds know how to find the files, and automake subdir-objects fails with it in place. (LXC_MONITOR_PROTOCOL_GENERATED, (LXC_MONITOR_GENERATED) (ACCESS_DRIVER_GENERATED, LOCK_PROTOCOL_GENERATED): Likewise. (*_client_bodies.h): Hard-code rules to write into srcdir, as VPATH tries to build $@ locally if missing. (util/virkeymaps.h): Likewise. (lxc/lxc_monitor_dispatch.h): Likewise. (access/viraccessapi*): Likewise. (locking/lock_daemon_dispatch_stubs.h): Likewise. * daemon/Makeflie.am (DAEMON_GENERATED, remote_dispatch.h): Likewise.

LibVirt : simple API for virtualization
Libvirt is a C toolkit to interact with the virtualization capabilities
of recent versions of Linux (and other OSes). It is free software
available under the GNU Lesser General Public License. Virtualization of
the Linux Operating System means the ability to run multiple instances of
Operating Systems concurrently on a single hardware system where the basic
resources are driven by a Linux instance. The library aim at providing
long term stable C API initially for the Xen paravirtualization but
should be able to integrate other virtualization mechanisms if needed.
