Re: [ferret_users] HDF5 error when loading .nc files

Hi Neil,

A user (Henry) from Taiwan was also seeing this issue.  The HDF5 library is statically linked into the prebuilt Ferret package, if that is what you are using, so changes in the dynamic libraries won't have an affect.  Henry was able to build Ferret from the GitHub repository using Homebrew packages built/installed on his system, and that build worked fine for him.  So if you are build it yourself and seeing this issue, let me know.

I will be adding a document in the GitHub repository on how to build Ferret on Mac OS X using Homebrew that is similar to that given for PyFerret.  (And yes, a Homebrew recipe would be better.)  So if you are comfortable using GitHub and Homebrew, this might be the best solution for getting (and updating) Ferret for your system.

Kind regards,

Hi All

Having just upgraded to Ferret 7.4 (on a Mac, OSX 10.11.6), I now seem unable to use netcdf files in Ferret. I have tried reinstalling both HDF5 and netcdf, and as well as a few different versions of HDF5 (1.10.1 and 1.8.18), and have also reinstalled Ferret. However, I still get the error below:  

(I can get to crash using the tutorial, which I suppose is handy in keeping things reproducible!)

  FERRET v7.4 (optimized)
  Darwin 15.6.0 - 04/16/18

! To begin we inform FERRET of the "data set" of interest using the
! SET DATA command.  The ETOPO60 data set contains the relief of the
! surface of the earth at 120 minute resolution


SET DATA etopo120
**ERROR Ferret crash; signal = 4
HDF5: infinite loop closing library

Has anyone else come across this issue?

Kind regards
