Hi, HDF5 experts,

I found out some information on *Scientific Data Sets* (SD API)
<http://www.hdfgroup.org/training/HDFtraining/UsersGuide/SDS_SD.fm1.html>,
but I can't build its examples at this link.

https://www.hdfgroup.org/training/HDFtraining/UsersGuide/UG_BookLOE.html#13731

Thanks for any help!

Hello Jianxin,

The mfhdf.h header file is provided with the HDF4 software, and is required for invoking SD interface routines.
If you do not have the HDF4 software, you can obtain it from this location:

    https://www.hdfgroup.org/release4/obtain.html

Pre-built HDF4 binaries for Linux and Windows are provided there, and you can also obtain the HDF4 source code to build.

ASCII versions of the examples in the HDF4 User’s Guide can be obtained from here:

   https://www.hdfgroup.org/release4/examples/ug-examples.html

For more information about HDF4, see the HDF4 home page:

    https://www.hdfgroup.org/products/hdf4/

You mentioned “HDF5”. Please note that HDF4 and HDF5 are different formats.

HDF5 can be obtained from this page: https://www.hdfgroup.org/HDF5/release/obtain5.html
The HDF5 home page is located here: https://www.hdfgroup.org/HDF5/

If you need help installing and/or using HDF4 or HDF5 just let me know!

Hi, Barara,

Thanks for your quick reply.

I need to implement a data logger feature and SD is very close to what I
want. But, based on the HDF5 introduction, any new development should use
HDF5 instead of HDF4, so is there any plan to support SD interface in HDF5
or users have to implement themselves?

Regards,

JC

Hi JC,

Yes, if you are developing new software please use HDF5 and do not use HDF4. You should be able to do in HDF5
what you can do with the SD interface in HDF4 (and more).

Feel free to contact the HDF Helpdesk (help@hdfgroup.org) if you encounter any issues learning HDF5.

We have a tutorial here:

   https://www.hdfgroup.org/HDF5/Tutor/introductory.html

We also have many example programs here:

   https://www.hdfgroup.org/HDF5/examples/

You can obtain the HDF5 software here:

   https://www.hdfgroup.org/HDF5/release/obtain5.html

Let us know if we can help!
