Optimize Doxygen build process by skipping rebuilds when input files are unchanged, using timestamp checks in CMake configuration.
Behavior:
Skip Doxygen build if input files unchanged using timestamp check in CMakeLists.txt, hl/src/CMakeLists.txt, and src/CMakeLists.txt.
Introduces stamp files (hdf5lib_doc.stamp, hdf5hllib_doc.stamp) to track changes.
Documentation:
add_custom_command and add_custom_target used to manage Doxygen builds.
Shared Doxygen content inputs defined in top-level CMakeLists.txt for reuse.
Misc:
Reorder add_subdirectory(src) in CMakeLists.txt for visibility of Doxygen variables.
Build-tree exports can't diverge from install-tree exports — the export(EXPORT ...) reads directly from the install export sets. No manual list to keep in sync.
Removed 3 global variables (HDF5_STATIC_LIBRARIES_TO_EXPORT, HDF5_JAVA_LIBRARIES_TO_EXPORT, HDF5_UTILS_TO_EXPORT) and their ~21 set_global_variable calls across tool/utility files.
Fixed the static-only build bug in the PR where the base export set was guarded by BUILD_SHARED_LIBS, breaking tools export.
Removed redundant utils in export files — the PR was dumping tools into all three build-tree export files (java, static, shared). Now they correctly appear only in the base export.
Refactor the cross-compilation infrastructure to rely on the standard
CMAKE_CROSSCOMPILING_EMULATOR variable instead of the custom
CROSSCOMPILING_PATH environment hack.
Key changes:
- Removed `ENVIRONMENT "${CROSSCOMPILING_PATH}"` from all test definitions.
- Updated custom commands (e.g., H5match_types, H5_gen) to invoke the
emulator explicitly when cross-compiling.
- Updated ConfigureChecks.cmake and HDF5UseFortran.cmake to enable
`try_run` checks when an emulator is defined.
- Added config/toolchain/mingw-w64-x86-64-wine.sh wrapper to automatically
locate MinGW runtime libraries (like libgfortran) for Wine execution.
- Cleaned up toolchain files to remove hardcoded emulator paths, deferring
configuration to the build environment.
Adds predefined datatypes for FP6 data in E2M3 and E3M2 formats
Does not add support for any native FP6 types; datatype conversions are performed in software
Adds predefined datatypes for FP8 data in E4M3 and E5M2 formats
Does not add support for any native FP8 types; datatype conversions are performed in software
Change default file format to 1.8 across various tests and examples, updating file creation and access logic accordingly.
Behavior:
Default file format version changed to 1.8 in H5Pfapl.c.
Updated file creation and access to use 1.8 format in h5ex_g_compact.c and test_file_image.c.
Set earliest file format in multiple test files including cache_tagging.c, dtypes.c, and links.c.
Tests:
Modified expected output in tools/test/misc/expected/*.ls files to reflect new file format locations.
Adjusted test logic in test_file_image.c and cache_tagging.c to accommodate format changes.
Misc:
Added comments and TODOs for future format testing in test_file_image.c.
Minor variable renaming for clarity in test_file_image.c.
Behavior:
Modify HDF5UseFortran.cmake to handle cross-compilation by providing default KINDs and sizes when CMAKE_CROSSCOMPILING is true.
Default values for INTEGER and REAL KINDs and their sizes are set when cross-compiling.
Error messages are adjusted to reflect cross-compilation scenarios.
Logic:
Conditional checks added for CMAKE_CROSSCOMPILING to determine if default values should be used.
Default values include INTEGER KINDs {1,2,4,8,16} and REAL KINDs {4,8,10,16}.
Default sizes for native kinds are set to 4 for INTEGER and REAL, and 8 for DOUBLE PRECISION when cross-compiling.
Misc:
Adjustments to verbose messages to indicate when defaults are used during cross-compilation.
Adds predefined datatypes for little- and big-endian bfloat16 data
Does not add support for any native bfloat16 types; datatype conversions are performed in software
Also adds missing float16 predefined types to fortran
* Remove hbool_t from the public API
This was previously removed from the source code, but the API calls
retained hbool_t in the public API calls. This commit removes
hbool_t from the public APIs.
hbool_t is retained as a typedef for bool in H5public.h so existing
code doesn't break.
Implemented missing --help/-h, -c, -echo and -shlib/-noshlib options
Added new -nohl option to avoid building and linking against
high-level HDF5 libraries if desired
Implemented adding of HDF5 installation library directory to rpath of
resulting executable/library and added new -norpath option to avoid
this behavior if desired
Added parsing of HDF5_USE_SHLIB environment variable to determine
whether to link against shared or static HDF5 libraries
Added parsing of HDF5_PKG_CONFIG_ARGS environment variable to separate
pkg-config-specific options from compiler-specific options and prevent
conflicts
* Refactor warning macros
Replaces the scheme in H5warnings.h with a more compiler-agnostic
one that relocates ifdef complexity to the warnings header file
and uses better naming.

* Simplify H5api_adpt.h
This change also uses the shared markup (e.g., __declspec) in both
static and shared libraries as the shared markup is ignored when
building static libs.
* Renamed some API decorations
Some API decorations (used to hide __declspec on Windows, among other
things) have been renamed:
H5_DLLCPP(VAR) --> H5CPP_DLL(VAR)
H5_HLDLL(VAR) --> H5HL_DLL(VAR)
H5_HLCPPDLL(VAR) --> H5CPP_HL_DLL(VAR)
H5_FCDLL(VAR) --> H5FC_DLL(VAR)
H5_FCTESTDLL(VAR) --> H5FC_TEST_DLL(VAR)
HDF5_HL_F90CSTUBDLL(VAR) --> H5FC_HL_DLL(VAR)
The shared library decorations are also now used when building static
libraries (where they are meaningless and ignored).
* h5cc: Allow overriding the compilers written into the file
Add a set of `HDF5_H5CC_C_COMPILER`, `HDF5_H5CC_CXX_COMPILER`
and `HDF5_H5CC_Fortran_COMPILER` CMake variables that can be used to
override the compiler string written into `h5cc`, `h5c++`, etc. This is
particularly useful when e.g. using ccache during the build,
as the ccache path otherwise ends up in `h5cc`.
Makes testing parameters specified with AddTest non-const again when
passed to test functions. This allows test functions to update their
parameters during execution and is particularly useful for tests
which use those parameters to accumulate statistics, error counts,
etc. without resorting to global variables.
The hash_size parameter of H5Iregister_type() hasn't been used since 1.8.
It's been removed and the API call has been versioned.
This PR also updates the make_vers script to handle v2.0.0.
Fixes#4344

number datatype from an ID of a base floating-point datatype
Adds the new feature check macros H5_HAVE_COMPLEX_NUMBERS and
H5_HAVE_C99_COMPLEX_NUMBERS
Adds the new datatype size macros H5_SIZEOF_FLOAT_COMPLEX,
H5_SIZEOF_DOUBLE_COMPLEX and H5_SIZEOF_LONG_DOUBLE_COMPLEX
Adds the new datatype ID macros H5T_NATIVE_FLOAT_COMPLEX,
H5T_NATIVE_DOUBLE_COMPLEX, H5T_NATIVE_LDOUBLE_COMPLEX,
H5T_CPLX_IEEE_F16LE, H5T_CPLX_IEEE_F16BE,
H5T_CPLX_IEEE_F32LE, H5T_CPLX_IEEE_F32BE,
H5T_CPLX_IEEE_F64LE and H5T_CPLX_IEEE_F64BE
Adds hard and soft datatype conversion paths between complex number
datatypes and all the integer and floating-point datatypes, as well as
between other complex number datatypes
Adds a special conversion path 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 converted directly
Adds support for complex number datatypes to the h5dump, h5ls and
h5diff/ph5diff tools. Allows h5dump '-m' option to change floating-point
printing format for float complex and double complex datatypes, as well
as long double complex if it has the same size as double complex
Adds minimal support to the h5watch and h5import tools
Adds support for the predefined complex number datatypes and
H5Tcomplex_create function to the Java wrappers. Also adds initial,
untested support to the JNI for future use with HDFView
Adds support for just the H5T_COMPLEX datatype class to the Fortran
wrappers
Adds support for the predefined complex number datatypes and
H5Tcomplex_create function to the high level library H5LT interface
for use with the H5LTtext_to_dtype and H5LTdtype_to_text functions
Changes some usages of "complex" in the library since it conflicts with
the "complex" keyword from the complex.h header. Also changes various
usages of the word "complex" throughout the library to distinguish
compound datatypes from complex datatypes.
This is where most people will expect to find license information. The
COPYING_LBNL_HDF5 file has also been renamed to LICENSE_LBNL_HDF5.
The licenses are unchanged.
* Fix for issue #4849 that settings in fapl libver bounds causes unexpected H5Fopen failures.
File with non-SWMR-write access can now be opened without regard for superblock version.
Due to the fix, H5Fstart_swmr_write() also needs to be modified as well as the tests for libver bounds.
The "RFC: Setting Bounds for Object Creation in HDF5 1.10.0" is also updated to reflect the changes.
* Fix c++ libver bound test failure.
Added setup and cleanup callback parameters to TestInit() to perform
setup and cleanup tasks once for whole test program
Removed TestCleanup() function since its functionality is covered by
PerformTests()
Added check of the HDF5_NOCLEANUP environment variable in
GetTestCleanup()

split them away from h5test.h and from test programs that don't
integrate with the testframe.c testing framework
Added new test setup callback to testframe.c testing framework
Added parameters to AddTest() to specify size of test parameters so they
can be copied for later use
