Thanks - I downloaded the maint branch (so I am 11 hours out of date!)
and built that - the advection diffusion example now runs. Somewhat
annoyingly, it doesn't seem to produce any output. Time to add a few
printf statements I guess.

Sorry for the noise. I understand why I got the above error
message but now I get a different one where previously the example
used to work. I have no idea what I have done differently.

The argument list for PetscOptionsGetInt() changed in this release (so
we could have reentrant option functions). It added an
additional argument at the beginning. I am guessing there is a
mismatch here between the version from which ex1.c comes
and the version you are linking.

Here's how I built the example
