HDF5 header files

[Alexander-Barth]

I would like to build the NetCDF library which requires HDF5. Unfortunately, the current HDF5_jll, does not install the header files. The windows msys2 package (http://repo.msys2.org/mingw/i686/mingw-w64-i686-hdf5-1.10.5-1-any.pkg.tar.xz) does actually include the necessary header files, but the python whl do not. But apparently, they correspond to HDF5 1.10.4, and presumably they can be extract from https://bitbucket.hdfgroup.org/projects/HDFFV/repos/hdf5/branches?base=hdf5-1_10_4, unless there is some better idea...

Thanks!

$ strings  libhdf5.103.dylib | grep 'HDF5 library version'

If only HDF5 could be properly cross-compiled... It looks like they're working on it, but last time I tried (a couple of weeks ago) I didn't see any concrete improvement.

It's a bit off-topic here, but I need this as a reminder: @sairus7 has built HDF5 for Raspberry Pi: https://yadi.sk/d/DnepMvNrYm77iw

Actually my previous message was not that unrelated: the tarball provided contains the header files, I'm using them to provide the headers for all platforms in #386

Unfotunately, the HDF5 header files from Linux-ARM require the existence of a feature.h file which is not the case for x86_64-w64-mingw32. The hdf5.h file in the updated HDF5_jll file can thus not be used on Windows.

configure:17968: cc -c -I/workspace/destdir/include  conftest.c >&5

Here I compare the H5pubconf.h from ARM (currently installed) and from mingw64:

sandbox:${WORKSPACE}/srcdir/netcdf-c-4.7.2/mingw64/include # grep -i feature /workspace/srcdir/netcdf-c-4.7.2/mingw64/include/H5pubconf.h /workspace/destdir/include/H5pubconf.h 
/workspace/srcdir/netcdf-c-4.7.2/mingw64/include/H5pubconf.h:/* Define to 1 if you have the <features.h> header file. */
/workspace/srcdir/netcdf-c-4.7.2/mingw64/include/H5pubconf.h:/* #undef H5_HAVE_FEATURES_H */
/workspace/destdir/include/H5pubconf.h:/* Define to 1 if you have the <features.h> header file. */
/workspace/destdir/include/H5pubconf.h:#define H5_HAVE_FEATURES_H 1

Actually, the mingw64 package includes the header files. I would propose to use these on Windows.

Why are the header files platform-dependent in the first place? Why is HDF5 so messy?
