hdf5 @1.10.6 +openmpi: error: implicit declaration of function 'H5CX_set_coll_metadata_read' is invalid in C99

[chaochinyang (Chao-Chin Yang)]

I need to build a parallel HDF5 to work with my C++ code, so I try to install hdf5 with all three of +cxx, +hl, and +openmpi on. But it fails to build due to some error in t_cache.c:

:info:build t_cache.c:7253:9: error: implicit declaration of function 'H5CX_set_coll_metadata_read' is invalid in C99 [-Werror,-Wimplicit-function-declaration]
:info:build         H5CX_set_coll_metadata_read(TRUE);
:info:build         ^
:info:build t_cache.c:7253:9: note: did you mean 'H5Pset_coll_metadata_write'?
:info:build ../src/H5Ppublic.h:365:15: note: 'H5Pset_coll_metadata_write' declared here
:info:build H5_DLL herr_t H5Pset_coll_metadata_write(hid_t plist_id, hbool_t is_collective);
:info:build               ^
:info:build 1 error generated.

The full log is attached.

My openmpi (default) is @4.0.1_1 with +gcc10 and my MacOS is 10.15.6.

Implicit declaration of function errors are new in Xcode 12. We need to fix them, but until we do, if you want to avoid the problem, downgrade to Xcode 11 and/or the Xcode 11 version of the command line tools.

There was a previous attempt to deal with implicitly defined functions, but maybe there is more needed for non-default variants: [691e48ba5e/macports-ports]

[chrstphrchvz (Christopher Chavez)]

There is a recent update available (1.10.7, 2020-09-15); it looks like it might address this issue.

[chaochinyang (Chao-Chin Yang)]

When will be the update published for downstream upgrade?

PR opened to update to 1.10.7: ​https://github.com/macports/macports-ports/pull/8530

I can confirm that a parallel HDF5 can be installed with 1.10.7.
