[petsc-users] Error in creating compressed data using HDF5

[Smith, Barry F.]

  You could try the master branch of PETSc that uses a much more recent branch of hdf5 

  When you did the --download-hdf5 did you also do --download-zlib and --download-szlib (though I would hope hdf5 would give you a very useful error message that they need to be installed instead of the vague error message they do provide.)
