What happens is that prior to the problem point, gnulib-tool was installing binary-io.h in the test directory, as it was a dependency for tests but not for files used directly by libvirt. After the problem point, one of our gnulib updates picked up some dependency changes that graduated binary-io.h into our normal include space, for use as part of libvirt (or at least as part of the gnulib modules compiled directly into libvirt and not just the testsuite). Meanwhile, version skew between the two versions of binary-io.h mean that if you pick up the wrong version, you get a compilation failure. Nuke the file in gnulib/tests/ to proceed. That can be done with a clean build, rather than an incremental build. I'm cc'ing bug-gnulib, though, in case there is a way to make 'gnulib-tool --update' (and/or ./bootstrap) remove old files from the tests directory once they have been graduated into the main directory as a result of some other module dependency change. -- Eric Blake eblake@xxxxxxxxxx +1-919-301-3266 Libvirt virtualization library http://libvirt.org
