[Octave-bug-tracker] [bug #38928] configure -> hdf5 doesn't handle path through

[Mike Miller]

Follow-up Comment #10, bug #38928 (project octave):

Sure, a clean build with


--with-hdf5-includedir=/usr/include/hdf5/serial
--with-hdf5-libdir=/usr/lib/x86_64-linux-gnu/hdf5/serial


fails in many, many places.

I get the same missing header file error with generation of the .df files in
corefcn, octave-value, with libinterp/octave.cc, libinterp/builtins.cc,
libinterp/corefcn/oct-errno.cc, just to name a few.

I think the problem is basically because hdf5.h is included in the public API
and leaks into all ov*.h header files. After a successful (patched) build, I
count almost 400 files that depend on hdf5.h, looking in the generated .Plo
and .Po files. So it may have to be added to essentially all CPPFLAGS in
libinterp and libgui.
