Greetings,

I would like to export the L2_LAC_OC file to HDF5 file via gpt.sh (v7.5) in command line, but it didn't work. The error is :

[optics@localhost tmp]$ /home/optics/seadas-7.5/bin/gpt.sh /home/optics/tmp/A2017243214000_gpt.xml -t /mnt/da81fa5a-016e-4718-a7ed-b89f4cd59da5/saltonsea/A2017243214000_niglas.h5 -f 'HDF5' /home/optics/tmp/A2017243214000_QKM.L2_LAC_OC

Error: No data product writer for the 'HDF5' format available


This command works well in the v7.4. According to the previous post, I find the jhdf5.jar and libjhdf5.so in ~/optics/seadas-7.4/modules/lib-hdf-2.7/lib
But the ~/seadas-7.5/modules/lib-hdf-2.7 was a jar file in v7.5, not a directory. In the jar file, jhdf5.jar and libjhdf5.so did be located under lib,
lib/jdf.jar
lib/jhdf5.jar
lib/linux64/libjhdf.so
lib/linux64/libjhdf5.so

However, I can not find these files in my system:
[optics@localhost modules]$ which libjhdf.so
/usr/bin/which: no libjhdf.so in (/home/optics/seadas/lcps:/home/optics/ocssw/run/bin3/linux_64:/home/optics/ocssw/run/scripts:/home/optics/ocssw/run/bin/linux_64:/home/optics/seadas-7.5/bin:/usr/local/bin:/usr/bin:/usr/local/sbin:/usr/sbin:/home/optics/.local/bin:/home/optics/bin)

And, in fact, the exporting as a NetCDF4-CF file works in, only the HDF-5 file can not be exported.

I'm not sure if the lost these files caused the problem, or something else? Could someone give me some suggestions?

Yes, we have had trouble with the HDF5 libraries not being found.  Which is really strange since NetCDF4 uses the HDF5 libraries to write its file.
We will look into this.  In the interim, you can easily read a NetCDF4 file with an HDF5 program.

Thanks, Don. So, for now, I have to write a NetCDF4 file.

Yes, until we can resolve the HDF5 lib problem
