hdf5 1.14.1-1.5.9 is broken on Windows for hdf.hdf5lib.H5 bindings

[mkitti]

hdf5-1.14.1-1.5.9-windows-x86_64.jar contains only three DLLs:

1. hdf5_java.dll
2. jni_hdf5.dll
3. jni_hdf5_java.dll

hdf5_java.dll depends on hdf5.dll which does not exist. The other two DLLs do not seem to depend on hdf5.dll but perhaps statically link it?

[saudet]

Works fine for me, but that can always be enhanced

[mkitti]

I do not see a clear option in the build to statically include the library. This also poses an issue for plugins.

The quickest fix I can think of would be to preload hdf5.dll in

javacpp-presets/hdf5/src/main/java/org/bytedeco/hdf5/hdf5_java.java

Line 43 in bdba6a2

@Platform(preload = {"hdf5_java"}),

Would it also be possible to have the JNI libraries also dynamically link that?

I'm confused about what makes Windows distinct from the other platform builds here. Why are the jni* libs statically linked to HDF5 on Windows?

[saudet]

It didn't work before, if it works now, great!

[saudet]

I've tried it again with HDF5 1.14.3 and it still doesn't work. The problem on Windows is that most symbols don't get exported from the DLLs, so they are not actually usable. This isn't something related to JavaCPP, so it should be fixed upstream.

[mkitti]

I'm unclear which DLL we are talking about. The main hdf5.dll, which should export the symbols is not being packaged.

[saudet]

That DLL doesn't contain the C++ API.

[mkitti]

• hdf5.dll contains and exports the C API.
• hdf5_cpp.dll contains and exports the C++ API.

hdf5_cpp.dll exports only some of the C++ API. It's not actually usable. That needs to be fixed.
