New Features
|
|
============
|
|
|
|
Configuration:
|
|
-------------
|
|
- Renamed the option: HDF5_ENABLE_Z_LIB_SUPPORT
|
|
|
|
The option has been renamed to HDF5_ENABLE_ZLIB_SUPPORT to be consistent
|
|
with the naming of other options.
|
|
|
|
- Added support for MinGW + MSYS2 when building with CMake
|
|
|
|
We previously added support for this to the Autotools and the appropriate
|
|
configure-time checks have been added to CMake.
|
|
|
|
CMake + MinGW + MSYS2 is now tested with the following environments:
|
|
|
|
* mingw32
|
|
* mingw64
|
|
* ucrt64
|
|
* clang64
|
|
|
|
- Added CMake build mode flags to the libhdf5.settings file
|
|
|
|
Flags from the CMake build mode (e.g., optimization) are not a part of
|
|
CMAKE_<language>_FLAGS and were not exported to the libhdf5.settings file. This
|
|
has been fixed and the C, Fortran, and C++ build mode flags are now exported to
|
|
the file.
|
|
|
|
This also affects the text output of H5check_version() and the libhdf5.settings
|
|
string stored in the library (for those who use strings(1), etc. to get
|
|
build info from the binary).
|
|
|
|
- CMake: Split compiler specific flags into separate files
|
|
|
|
The compiler specific flags have been split into separate files to make
|
|
it easier to maintain and add new compiler flags. The flags for NVHPC,
|
|
Intel, GNU and Clang compilers are now in separate files included from
|
|
the current compiler flags files; HDFCompiler<language>Flags.cmake.
|
|
|
|
- Added a configuration option for internal threading/concurrency support:
|
|
|
|
CMake: HDF5_ENABLE_THREADS (ON/OFF) (Default: ON)
|
|
Autotools: --enable-threads (yes/no) (Default: yes)
|
|
|
|
This option enables support for threading and concurrency algorithms
|
|
within the HDF5 library. It is required for, but separate from, the
|
|
'threadsafe' configure option, which makes the HDF5 API safe to call from
|
|
multiple threads. It is possible to enable the 'threads' option and
|
|
disable the 'threadsafe' option, but not vice versa. The 'threads' option
|
|
must be on to enable the subfiling VFD.
|
|
|
|
- Added support for native zlib-ng compression.
|
|
|
|
Changed the zlib-ng CMake logic to prefer the native zlib-ng library. Added
|
|
#ifdef around the compression function calls. Added including the correct
|
|
header file with the same #ifdef.
|
|
|
|
- Renamed remaining HDF5 library CMake options except for CMake BUILD* variables
|
|
|
|
DEFAULT_API_VERSION to HDF5_DEFAULT_API_VERSION
|
|
DISABLE_PDB_FILES to HDF5_DISABLE_PDB_FILES
|
|
ONLY_SHARED_LIBS to HDF5_ONLY_SHARED_LIBS
|
|
ALLOW_UNSUPPORTED to HDF5_ALLOW_UNSUPPORTED
|
|
TEST_SHELL_SCRIPTS to HDF5_TEST_SHELL_SCRIPTS
|
|
|
|
All other HDF5 library CMake options are prefixed with HDF5_
|
|
|
|
- bin/cmakehdf5 has been removed
|
|
|
|
This was an unsupported build script that made building HDF5 via CMake
|
|
work like building HDF5 via the Autotools. It has been unmaintained
|
|
for a long time, has been marked deprecated, and is being removed.
|
|
|
|
- Generated files in src are now checked into version control
|
|
|
|
These files are infrequently updated and generating them adds a
|
|
dependency on Perl. The listed files are now checked in and do
|
|
not need to be recreated when checking out development branches.
|
|
|
|
* H5Edefin.h
|
|
* H5Einit.h
|
|
* H5Emajdef.h
|
|
* H5Emindef.h
|
|
* H5Epubgen.h
|
|
* H5Eterm.h
|
|
* H5overflow.h
|
|
* H5version.h
|
|
|
|
- Dropped some old Solaris Studio work-arounds
|
|
|
|
Solaris Studio no longer seems to be maintained and the last version
|
|
(12.4, circa 2015) doesn't seem to fully support C11. We've removed
|
|
some hacks that work around things like __attribute__() support.
|
|
|
|
- Dropped support for the traditional MSVC preprocessor
|
|
|
|
Visual Studio has recently started using a standards-compliant
|
|
preprocessor (In VS2019+) and this is the default in C11.
|
|
|
|
https://learn.microsoft.com/en-us/cpp/preprocessor/preprocessor-experimental-overview?view=msvc-170
|
|
|
|
Because of this, we've dropped support for the traditional
|
|
MSVC preprocessor.
|
|
|
|
- The standard for building the library is now C11
|
|
|
|
We have updated the build files to set the C standard to C11, though
|
|
some platforms use gnu11 to get some GNU things to work.
|
|
|
|
|
|
|
|
Library:
|
|
--------
|
|
- H5F_LIBVER_LATEST is now an enum value
|
|
|
|
This was previously #defined to the latest H5F_libver_t API version, but
|
|
is now an enum value with an integer value equal to the latest H5F_libver_t
|
|
API version's value. e.g.:
|
|
|
|
<snip>
|
|
H5F_LIBVER_V200 = 5,
|
|
H5F_LIBVER_LATEST = 5,
|
|
</snip>
|
|
|
|
- Added support for complex number datatypes
|
|
|
|
Support for the C99 "float _Complex", "double _Complex" and "long double _Complex"
|
|
(with MSVC, "_Fcomplex", "_Dcomplex" and "_Lcomplex") types has been added for
|
|
platforms/compilers that support them. These types have been implemented with a
|
|
new datatype class, H5T_COMPLEX. Note that any datatypes of class H5T_COMPLEX
|
|
will not be readable with previous versions of HDF5. If a file is accessed with
|
|
a library version bounds "high" setting less than H5F_LIBVER_V200, an error will
|
|
occur if the application tries to create an object with a complex number datatype.
|
|
If compatibility with previous versions of HDF5 is desired, applications should
|
|
instead consider adopting one of the existing conventions at
|
|
https://nc-complex.readthedocs.io/en/latest/#conventions-used-in-applications.
|
|
|
|
The following new macros have been added:
|
|
|
|
- H5_HAVE_COMPLEX_NUMBERS
|
|
|
|
This macro is defined in H5pubconf.h and will have the value 1 if native
|
|
support for complex numbers is available. It will not be defined otherwise.
|
|
|
|
- H5_HAVE_C99_COMPLEX_NUMBERS
|
|
|
|
This macro is defined in H5pubconf.h and will have the value 1 if native
|
|
support for C99 complex numbers is available. It will not be defined otherwise.
|
|
If this macro is not defined but H5_HAVE_COMPLEX_NUMBERS is defined, the
|
|
complex number types supported are the MSVC types.
|
|
|
|
- H5_SIZEOF_FLOAT_COMPLEX
|
|
|
|
This macro is defined in H5pubconf.h and will have a value corresponding
|
|
to the size of the native float complex datatype, as computed by sizeof().
|
|
If C99 complex number support is available, this will be the size of the
|
|
"float _Complex" type. Otherwise, it will be the size of the "_Fcomplex"
|
|
type. It will have the value 0 if support for a native float complex datatype
|
|
is not available.
|
|
|
|
- H5_SIZEOF_DOUBLE_COMPLEX
|
|
|
|
This macro is defined in H5pubconf.h and will have a value corresponding
|
|
to the size of the native double complex datatype, as computed by sizeof().
|
|
If C99 complex number support is available, this will be the size of the
|
|
"double _Complex" type. Otherwise, it will be the size of the "_Dcomplex"
|
|
type. It will have the value 0 if support for a native double complex datatype
|
|
is not available.
|
|
|
|
- H5_SIZEOF_LONG_DOUBLE_COMPLEX
|
|
|
|
This macro is defined in H5pubconf.h and will have a value corresponding
|
|
to the size of the native long double complex datatype, as computed by sizeof().
|
|
If C99 complex number support is available, this will be the size of the
|
|
"long double _Complex" type. Otherwise, it will be the size of the "_Lcomplex"
|
|
type. It will have the value 0 if support for a native long double complex
|
|
datatype is not available.
|
|
|
|
- H5T_NATIVE_FLOAT_COMPLEX
|
|
|
|
This macro maps to the ID of an HDF5 datatype representing the native C
|
|
float complex datatype (either "float _Complex" or "_Fcomplex") for the
|
|
platform. If support for a native float complex datatype is not available
|
|
(H5_HAVE_COMPLEX_NUMBERS is not defined), the macro will map to
|
|
H5I_INVALID_HID and should not be used.
|
|
|
|
- H5T_NATIVE_DOUBLE_COMPLEX
|
|
|
|
This macro maps to the ID of an HDF5 datatype representing the native C
|
|
double complex datatype (either "double _Complex" or "_Dcomplex") for the
|
|
platform. If support for a native double complex datatype is not available
|
|
(H5_HAVE_COMPLEX_NUMBERS is not defined), the macro will map to
|
|
H5I_INVALID_HID and should not be used.
|
|
|
|
- H5T_NATIVE_LDOUBLE_COMPLEX
|
|
|
|
This macro maps to the ID of an HDF5 datatype representing the native C
|
|
long double complex datatype (either "long double _Complex" or "_Lcomplex")
|
|
for the platform. If support for a native long double complex datatype is
|
|
not available (H5_HAVE_COMPLEX_NUMBERS is not defined), the macro will map
|
|
to H5I_INVALID_HID and should not be used.
|
|
|
|
- H5T_COMPLEX_IEEE_F16LE / H5T_COMPLEX_IEEE_F16BE
|
|
|
|
These macros map to IDs of HDF5 datatypes representing a complex number of
|
|
two parts, each of which is an IEEE 754 16-bit floating-point datatype in
|
|
little- or big-endian order. These datatypes are available regardless of
|
|
whether complex number support is available or not.
|
|
|
|
- H5T_COMPLEX_IEEE_F32LE / H5T_COMPLEX_IEEE_F32BE
|
|
|
|
These macros map to IDs of HDF5 datatypes representing a complex number of
|
|
two parts, each of which is an IEEE 754 32-bit floating-point datatype in
|
|
little- or big-endian order. These datatypes are available regardless of
|
|
whether complex number support is available or not.
|
|
|
|
- H5T_COMPLEX_IEEE_F64LE / H5T_COMPLEX_IEEE_F64BE
|
|
|
|
These macros map to IDs of HDF5 datatypes representing a complex number of
|
|
two parts, each of which is an IEEE 754 64-bit floating-point datatype in
|
|
little- or big-endian order. These datatypes are available regardless of
|
|
whether complex number support is available or not.
|
|
|
|
The following new API function has been added:
|
|
|
|
hid_t H5Tcomplex_create(hid_t base_type_id);
|
|
|
|
Creates a new complex number datatype from the base datatype specified
|
|
by the given HDF5 ID `base_type_id`. The base datatype must be a
|
|
floating-point datatype.
|
|
|
|
The following new hard datatype conversion paths have been added, but
|
|
will only be used when complex number support is available:
|
|
|
|
H5T_NATIVE_SCHAR <-> H5T_NATIVE_FLOAT_COMPLEX | H5T_NATIVE_UCHAR <-> H5T_NATIVE_FLOAT_COMPLEX
|

|
|
H5T_NATIVE_LLONG <-> H5T_NATIVE_FLOAT_COMPLEX | H5T_NATIVE_ULLONG <-> H5T_NATIVE_FLOAT_COMPLEX
|
|
H5T_NATIVE_FLOAT16 <-> H5T_NATIVE_FLOAT_COMPLEX | H5T_NATIVE_FLOAT <-> H5T_NATIVE_FLOAT_COMPLEX
|
|
H5T_NATIVE_DOUBLE <-> H5T_NATIVE_FLOAT_COMPLEX | H5T_NATIVE_LDOUBLE <-> H5T_NATIVE_FLOAT_COMPLEX
|
|
|

|
|
H5T_NATIVE_LONG <-> H5T_NATIVE_DOUBLE_COMPLEX | H5T_NATIVE_ULONG <-> H5T_NATIVE_DOUBLE_COMPLEX
|

|
|
|
|
Alternative software implementation conversion paths have been added for all of
|
|
the above for use when native complex number support is not available. All of these
|
|
conversion paths follow the behavior outlined in the C standard for conversions of
|
|
complex number values.
|
|
|
|
Additionally, a special datatype conversion path has been added between complex number
|
|
datatypes and array or compound datatypes where the in-memory layout of data is the
|
|
same between the datatypes and data can be directly converted. This conversion path
|
|
is subject to the following rules:
|
|
|
|
- An array datatype must consist of exactly two elements where each element is of
|
|
the same floating-point datatype as the complex number datatype's base floating-point
|
|
datatype.
|
|
|
|
- A compound datatype must consist of exactly two fields where each field is of the
|
|
same floating-point datatype as the complex number datatype's base floating-point
|
|
datatype. The compound datatype must not have any leading or trailing structure
|
|
padding or any padding between its two fields. The fields must also have compatible
|
|
names, must have compatible offsets within the datatype and must be in the order
|
|
of "real" part -> "imaginary" part, such that the compound datatype matches the
|
|
following representation:
|
|
|
|
H5T_COMPOUND {
|
|
<float_type> "r(e)(a)(l)"; OFFSET 0
|
|
<float_type> "i(m)(a)(g)(i)(n)(a)(r)(y)"; OFFSET SIZEOF("r(e)(a)(l)")
|
|
}
|
|
|
|
where "r(e)(a)(l)" means the field may be named any substring of "real", such as
|
|
"r", or "re" and "i(m)(a)(g)(i)(n)(a)(r)(y)" means the field may be named any
|
|
substring of "imaginary", such as "im" or "imag".
|
|
|
|
Support for complex numbers has been added to the h5dump, h5ls and h5diff/ph5diff
|
|
tools. The h5dump command-line option '-m' can be used to change the floating-point
|
|
printing format for the float complex and double complex datatypes, as well as
|
|
the long double complex datatype if it has the same size as a double complex
|
|
datatype.
|
|
|
|
Support for the predefined complex number datatypes and the H5Tcomplex_create
|
|
function has been added to the Java wrappers. However, Java does not have
|
|
official types for complex numbers, so an application must be sure that
|
|
data is in an appropriate format in-memory when using these datatypes.
|
|
|
|
Support for the Fortran wrappers has not yet been added.
|
|
|
|
Support for the predefined complex number datatypes and the H5Tcomplex_create
|
|
function has been added to the high level library, allowing them to work
|
|
with the H5LTtext_to_dtype and H5LTdtype_to_text functions.
|
|
|
|
Simple example programs showing how to use complex number datatypes have
|
|
been added in the following files:
|
|
|
|
- HDF5Examples/C/H5T/200/h5ex_t_complex.c (Uses C99 complex number types)
|
|
- HDF5Examples/C/H5T/200/h5ex_t_complex_msvc.c (Uses MSVC complex number types)
|
|
- HDF5Examples/C/H5T/200/h5ex_t_complex_custom.c (Uses H5Tcomplex_create to create
|
|
a custom complex number type)
|
|
|
|
- FOR VOL DEVELOPERS: Renamed H5VLstart_lib_state and H5VLfinish_lib_state
|
|
|
|
The APIs H5VLstart_lib_state and H5VLfinish_lib_state have been renamed to
|
|
H5VLopen_lib_context and H5VLclose_lib_context, respectively, with the addition
|
|
of a "context" argument.
|
|
|
|
- Removed H5FDperform_init API routine. Virtual File Driver (VFD)
|
|
developers who wish to provide an ID for their driver should create
|
|
a routine specific to their individual implementation.
|
|
|
|
- H5Pset_external() now uses HDoff_t, which is always a 64-bit type
|
|
|
|
The H5Pset_external() call took an off_t parameter in HDF5 1.14.x and
|
|
earlier. On POSIX systems, off_t is specified as a 64-bit type via
|
|
POSIX large-file support (LFS). On Windows, however, off_t is defined
|
|
as a 32-bit type, even on 64-bit Windows.
|
|
|
|
HDoff_t has been added to H5public.h and is defined to be int64_t on
|
|
Windows and the library has been updated to use HDoff_t in place of
|
|
off_t throughout. The H5Pset_external() offset parameter has also been
|
|
updated to be HDoff_t.
|
|
|
|
There is no API compatibility wrapper for this change.

Tools:

------
|
|
- Added h5dump command option to set the floating point format for long double
|
|
|
|
The new option is --lformat, which allows the user to set the
|
|
floating point format for long double. The default format is %Lg.
|
|
There is already an option --format to set the floating point format
|
|
for double and float. The default format is %g.
|
|
|
|
- Remove the high-level GIF tools
|
|
|
|
The high-level GIF tools, h52gif and gif2h5, have unfixed CVE issues
|
|
(with no proof-of-concept files). They are not critical tools, are not
|
|
well maintained, and are an odd fit for building with the library.
|
|
Because of this, they have been removed. We may move them to a separate
|
|
repository in the future.
|
|
|
|
This also removes the following configure options:
|
|
|
|

Bug Fixes since HDF5-2.0.0 release
|
|
===================================
|
|
Library
|
|
-------
|
|
- Fixed a bug in the H5Oexists and H5Oexists_by_name API routines that
|
|
would cause those routines to return FAIL instead of FALSE when checking
|
|
the existence of a non-existent object with a file ID instead of a
|
|
group ID.
|
|
|
|
- Fixed a segfault in h5dump when a B-tree node level is corrupted
|
|
|
|
h5dump produced a segfault on a mal-formed file because a B-tree node
|
|
level was corrupted.
|
|
|
|
An internal function was modified to help detecting when a decoded B-tree
|
|
node level has an unexpected value and an error will be produced.
|
|
|
|
Fixes GitHub issue #4432
|
|
|
|
- Fixed H5Ovisit2 to recursively visit all objects
|
|
|
|
H5Ovisit2 visited only the root group and not all the nested groups.
|
|
|
|
This behavior occurred when the fields are not H5O_INFO_BASIC or
|
|
H5O_INFO_ALL because an internal function did not obtain the basic
|
|
information needed by its caller. This problem is now fixed.
|
|
|
|
Fixes GitHub issue #4941
|
|
|
|
- Only clear FE_INVALID when that symbol is present on the system
|
|
|
|
When we initialize the floating-point types at library startup, it's
|
|
possible to raise floating-point exceptions when we check which things
|
|
are supported. Normally, we clear these floating-point exceptions via
|
|
feclearexcept(FE_INVALID), but FE_INVALID may not be present on all
|
|
systems. Specifically, this was reported as being a problem when using
|
|
Emscripten 3.1.68 to compile HDF5 1.14.5 to WebAssembly.
|
|
|
|
We've added an #ifdef FE_INVALID block around the exception clearing
|
|
code to correct this.

|
-------------
|
|
- Changed name of libhdf5hl_fortran installed by autotools to libhdf5_hl_fortran. The
|

new name is consistent with the name of the lib when installed by CMake and with the
|
|
other hl libs.

Platforms Tested
|
|
===================
|
|
|
|
- HDF5 is tested with the two latest macOS versions that are available
|
|
on github runners. As new major macOS versions become available, HDF5
|
|
will discontinue support for the older version and add the new latest
|
|
version to its list of compatible systems, along with the previous
|
|
version.

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
|
|
LICENSE 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
|
