Hi,

During a test rebuild of HDF5's reverse dependcies against HDF5 2.1.0
currently in experimental, r-cran-hdf5r FTBFS with:

Wrapper_auto_H5FDfamily.c: In function ‘R_H5FD_family_init’:
Wrapper_auto_H5FDfamily.c:23:22: error: implicit declaration of function ‘H5FD_family_init’; did you mean ‘R_H5FD_family_init’? [-Wimplicit-function-declaration]
   23 |   hid_t return_val = H5FD_family_init();
      |                      ^~~~~~~~~~~~~~~~
      |                      R_H5FD_family_init


I know nothing about R unfortunately, so I cannot fix it by myself.

Thanks in advance,
_g.

Hi Gilles,

thank you for the patch.

How urgent is the issue?  Can I ask you to forward your patch upstream
at https://github.com/hhoeflin/hdf5r and give them a week or two to see
if they make a new release?

Have a nice day,

Charles
