Hi All,
I have a bunch of HDF4 files that I would like to convert to HDF5. So I head to the site to get "H4 / H5 Conversion Library: 2.1.1"
http://www.hdfgroup.org/ftp/HDF5/h4toh5/bin/H4H5Tools-2.1.1-win64.zip
Then I also downloaded HDF5 and HDF4 from
http://www.hdfgroup.org/ftp/HDF5/hdf5-1.8.5/bin/windows/HDF5-1.8.5-win64.zip
http://www.hdfgroup.org/ftp/HDF/HDF_Current/bin/windows/HDF4.2.5-win64-vs2005-ivf101.zip
After putting the directories into my PATH envrionment and trying to run "h4toh5.exe" from a command line, I got "The program can't start because szlibdll.dll is missing from your computer..." message. So I made a copy of szip.dll and szip.lib and renamed the copy as szlibdll.dll and szlibdll.lib. Then I tried "h4toh5.exe" again. Everything looks fine with usage message printed. However, when I tried with a HDF4 data file as "h4toh5.exe hdf4_file hdf5_file", I got "h4toh5.exe has stopped working A problem caused the program to stop working correctly..." The program crashed.

HDFView has no problem viewing that file. And I tested h4toh5.exe with the out.hdf in the ChunkBinary example at
http://www.hdfgroup.org/training/hdf4_chunking/ChunkBinary.tar
h4toh5.exe worked smoothly. I have uploaded the troubled HDF4 file at
ftp://ftp.renci.org/outgoing/dbltrbl100m.hdfgrdbas
Would you please take a look? I couldn't tell whether it is the h4toh5's limitation.

Thanks a lot.

Best,
xunlei
