[petsc-users] PetscOptionsBegin

[iwaddington .]

Hi everybody, I compiled the file
src/ksp/ksp/examples/tutorials/ex29.c.html<http://www.mcs.anl.gov/petsc/petsc-3.4/src/ksp/ksp/examples/tutorials/ex29.c.html>in
order to see how PetscOptionsBegin and PetscOptionsEnd work, but it
looks like nothing happens. There are no options popping on the terminal
for me to set. Thanks.
