Package: libhdf5-dev
Version: 1.8.16+docs-8+b1
Severity: normal
Hi.
The libhdf5-dev package ships a single .pc file: hdf5-serial.pc, which
contains
Libs: -L/usr/lib/x86_64-linux-gnu/hdf5/serial -lhdf5
This serves to link in the C interface to the HDF5 library by adding to
the LDLIBS in GNU Make:
$(shell pkg-config --libs hdf5-serial)
If, however, you have a project that uses the C++ interface, then you
need something uglier:
$(shell pkg-config --libs-only-L hdf5-serial) -lhdf5_cpp
This is also bad because it goes against the whole purpose of
pkg-config: the user now has to know about the internal layout of the
package.
It looks like we have 6 flavors of shared objects for hdf5-serial:
/usr/lib/x86_64-linux-gnu/hdf5/serial/libhdf5.so
/usr/lib/x86_64-linux-gnu/hdf5/serial/libhdf5_cpp.so
/usr/lib/x86_64-linux-gnu/hdf5/serial/libhdf5_fortran.so
/usr/lib/x86_64-linux-gnu/hdf5/serial/libhdf5_hl.so
/usr/lib/x86_64-linux-gnu/hdf5/serial/libhdf5_hl_cpp.so
/usr/lib/x86_64-linux-gnu/hdf5/serial/libhdf5hl_fortran.so
Would it make sense to ship a .pc file for each one?
Thanks!

I'm sorry for this very late answer.
Upstream provides pkg-config files for cmake builds only. The current
pkg-config for HDF5 in Debian were added by me, and are just minimalist
ones. They are not expected to work for every use case.
I've opened a feature request at the upstream github project:
https://github.com/HDFGroup/hdf5/issues/5194
Meanwhile, patches are welcome.
This was fixed in release 2.1.0+repack-1.
Best,
