How can I use functions for reading and writing in HDF5?

[HA_10767036]

I am a beginner who is currently using PTC MathCAD on a 30 day trial version.

I have two questions about how to use functions for reading and writing in HDF5.

①I have read the article published in 2016(https://www.ptc.com/ja/support/article/CS189647).

However I cannot use "ReadHDF", "WriteHDF" to read/write HDF5.

I obtained the HDF environment by following the workflow described in the word file in the zip.
(I downloaded the latest version 1.14.2, not ver 1.8.11 as described)

I have finished up to 2.) in the "Install and run the Mathcad_HDF.dll" in the word file,

but when I open Mathcad_HDF.mcdx file and type Mathcad_ReadHDF (or Mathcad_WriteHDF),
Mathcad crashes and the operation screen disappears.

Please tell me how to solve this problem.

②PTC told me that in order to use custom functions in the latest version of Mathcad,

we would need to rebuild DELL using Visual Studio or other software from the provided source,

but since custom functions are not a standard feature of Mathcad,

our support cannot provide detailed support.

Please tell me how to do what they say to do, which is to rebuild the DELL.

Hi,

you have to contact https://www.hdfgroup.org/ and discuss your problem with them.

If you have an access to Mathcad Prime 3.0 installation media, you can install it and test it.

I changed the HDF5 driver and it worked. Thank you!
