===================
- HDF5 supports the latest macOS versions, including the current and two
preceding releases. As new major macOS versions become available, HDF5
will discontinue support for the oldest version and add the latest
version to its list of compatible systems, along with the previous two
releases.

Known Problems
==============
- When building with the NAG Fortran compiler using the Autotools and libtool
2.4.2 or earlier, the -shared flag will be missing '-Wl,', which will cause
compilation to fail. This is due to a bug in libtool that was fixed in 2012
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:
H5PLUGIN-filter_plugin
H5TEST-flush2
H5TEST-testhdf5-base
MPI_TEST_t_filters_parallel
Sporadic failures (even with lower -O levels):
Java JUnit-TestH5Pfapl
Java JUnit-TestH5D
Also, NVHPC will fail to compile the test/tselect.c test file with a compiler
error of 'use of undefined value' when the optimization level is -O2 or higher.
This is confirmed to be a bug in the nvc compiler that has been fixed as of
23.11. If you are using an affected version of the NVidia compiler, the
work-around is to set the optimization level to -O1.

- CMake files do not behave correctly with paths containing spaces.
Do not use spaces in paths because the required escaping for handling spaces
results in very complex and fragile build files.
- At present, metadata cache images may not be generated by parallel
applications. Parallel applications can read files with metadata cache
images, but since this is a collective operation, a deadlock is possible
if one or more processes do not participate.
- The subsetting option in ph5diff currently will fail and should be avoided.
The subsetting option works correctly in serial h5diff.
- Flang Fortran compilation will fail (last check version 17) due to not yet
implemented: (1) derived type argument passed by value (H5VLff.F90),
and (2) support for REAL with KIND = 2 in intrinsic SPACING used in testing.
- Fortran tests HDF5_1_8.F90 and HDF5_F03.F90 will fail with Cray compilers
greater than version 16.0 due to a compiler bug. The latest version verified
as failing was version 17.0.
- Several tests currently fail on certain platforms:
MPI_TEST-t_bigio fails with spectrum-mpi on ppc64le platforms.
MPI_TEST-t_subfiling_vfd and MPI_TEST_EXAMPLES-ph5_subfiling fail with
cray-mpich on theta and with XL compilers on ppc64le platforms.
MPI_TEST_testphdf5_tldsc fails with cray-mpich 7.7 on cori and theta.
- File space may not be released when overwriting or deleting certain nested
variable length or reference types.
- Known problems in previous releases can be found in the HISTORY*.txt files
in the HDF5 source. Please report any new problems found to
help@hdfgroup.org.
CMake vs. Autotools installations
=================================
While both build systems produce similar results, there are differences.
Each system produces the same set of folders on Linux (only CMake works
on standard Windows); bin, include, lib and share. Autotools places the
COPYING and RELEASE.txt file in the root folder, CMake places them in
the share folder.
The bin folder contains the tools and the build scripts. Additionally, CMake
creates dynamic versions of the tools with the suffix "-shared". Autotools
installs one set of tools depending on the "--enable-shared" configuration
option.
build scripts
-------------
Autotools: h5c++, h5cc, h5fc
CMake: h5c++, h5cc, h5hlc++, h5hlcc
The include folder holds the header files and the fortran mod files. CMake
places the fortran mod files into separate shared and static subfolders,
while Autotools places one set of mod files into the include folder. Because
CMake produces a tools library, the header files for tools will appear in
the include folder.
The lib folder contains the library files, and CMake adds the pkgconfig
subfolder with the hdf5*.pc files used by the bin/build scripts created by
the CMake build. CMake separates the C interface code from the fortran code by
creating C-stub libraries for each Fortran library. In addition, only CMake
installs the tools library. The names of the szip libraries are different
between the build systems.
The share folder will have the most differences because CMake builds include
a number of CMake specific files for support of CMake's find_package and support
for the HDF5 Examples CMake project.
The issues with the gif tool are:
HDFFV-10592 CVE-2018-17433
HDFFV-10593 CVE-2018-17436
HDFFV-11048 CVE-2020-10809
These CVE issues have not yet been addressed and are avoided by not building
the gif tool by default. Enable building the High-Level tools with these options:
autotools: --enable-hlgiftools
cmake: HDF5_BUILD_HL_GIF_TOOLS=ON
