[petsc-users] Petsc versions

[Mark Adams]

I have this code:

#if PETSC_VERSION_GT(3,4,0) || !PETSC_VERSION_RELEASE
  ierr = KSPSetOperators(m_ksp,m_mat,m_mat);CHKERRQ(ierr);
#else
          ierr =
KSPSetOperators(m_ksp,m_mat,m_mat,SAME_NONZERO_PATTERN);CHKERRQ(ierr);
#endif

And it fails with a v3.4 at TACC (eg /opt/apps/intel13/mvapich2_1
_9/petsc/3.4/sandybridge/include).  It fails with too few arguments in the
first call.  So my #ifdefs are not working correctly.  I want the second
branch.  What would be the correct syntax for this?
