HDFView-3.3.0-win10_64-vs16 crashes opening a HDF4 file.

[hyoklee]

Test with the attached file. I tested it on Windows 10.

AIRS.2023.03.24.240.L2.SUBS2SUP.v7.0.7.0.G23084133451.hdf.gz

Looks like the HDF4 library is failing to load properly

Did install the HDFView with Installer or the Application Image version? The Application Image version requires you to setup all paths on windows for finding dlls.

[hyoklee]

@byrnHDF , you can tell from the file name in the title of this issue, can't you? App images has App in the zip file name.

[byrnHDF]

Assuming that the title indicates you used the installer, and from the first line of the capture output which indicates the AppImage install - it seems that the problem is independent of the install type.

[byrnHDF]

Upon further testing on a linux machine, this file crashes on opening as well. Must be something in the type of object trying to be opened.

[oyarzun]

@byrnHDF FYI, I've tried both the HDFView Windows installer and the application image. Both result in the same exception when trying to open any HDF4 file.

[byrnHDF]

Thanks, I am trying to figure out the scope of the failure as well as determine how it passed the small but useful testing we did do on hdf4.

[byrnHDF]

A quick fix is to install the hdf-4.2.16 release - this will add whatever is missing from hdf in hdfview.
There must be a dll that needs to be copied.

[hyoklee]

@loricooperhdf , @byrnHDF 's quick fix is an HDF Newsletter item.

[byrnHDF]

xdr.dll - that is the missing dll - copying that over to the folder with mfhdf.dll allows it to open.

However, the file provided at the top of this issue will open but crash opening a dataset. This is a different problem.

[byrnHDF]

xdr.dll - that is the missing dll - copying that over to the folder with mfhdf.dll allows it to open.

@loricooperhdf , @byrnHDF 's quick fix is an HDF Newsletter item.

Not yet, please. Just installing HDF4 is not a good answer - providing xdr.dll to download would be better, but not ideal.
There are other things that need to be discussed today that then could go in a newsletter.

The problem with the file is a hdf4 JNI issue See HDFGroup/hdf4#355

[byrnHDF]

Fix will be in next release
