I added a couple more print statements and turned on the debugging flags for ViennaCL, and now get the following output, if it helps to shed some light on what's going on. I'll now proceed to dive into the gmres source to try and figure things out! (Still baffled by Karl's compilation issues...) ViennaCL: Initializing new ViennaCL context.
