I don't see anything obvious that's wrong. I've just checked it now on 
my own system with the commit I rebased against and it's compiling ok.
I'm on F20 with 3.16. The part of the patch that adds the fuse library 
is below, so you could check to make sure it has applied ok.

master when I'm back in the office on Wednesday.

I can confirm this problem, at least on Ubuntu (14.10). I believe it is due to the fact that dependencies on shared objects (-lfuse) are not captured in .la files. Hence when executables are linked with libopenvswitch.a, the -lfuse link flag doesn't get added automatically.
I've seen this on another project but I'm not sure what is the proper solution. The difference with other shared objects (e.g. -ldl) is that those get added during configure step and land into $(LIBS) that then gets widely applied.

The easy workaround though is to add -lfuse to LIBS at ovs make invocation time:
 make LIBS=-lfuse
diff mbox
