and released in 2.4.4 in 2014.
When the library detects and builds in support for the _Float16 datatype, an
issue has been observed on at least one MacOS 14 system where the library
fails to initialize due to not being able to detect the byte order of the
_Float16 type (https://github.com/HDFGroup/hdf5/issues/4310):
#5: H5Tinit_float.c line 308 in H5T__fix_order(): failed to detect byte order
major: Datatype
minor: Unable to initialize object
If this issue is encountered, support for the _Float16 type can be disabled
with a configuration option:
CMake: HDF5_ENABLE_NONSTANDARD_FEATURE_FLOAT16=OFF
Autotools: --disable-nonstandard-feature-float16
When HDF5 is compiled with NVHPC versions 23.5 - 23.9 (additional versions may
also be applicable) and with -O2 (or higher) and -DNDEBUG, test failures occur
in the following tests:
