New Features
|
|
============
|
|
|
|
Configuration:
|
|
-------------
|
|
- Update CMake tests to use FIXTURES
|
|
|
|
CMake test fixtures allow setup/cleanup tests and other dependency
|
|
requirements as properties for tests. This is more flexible for
|
|
modern CMake code.
|
|
|
|
(ADB - 2019/07/23, HDFFV-10529)
|
|
|
|
- Windows PDB files are always installed
|
|
|
|
There are build configuration or flag settings for Windows that may not
|
|
generate PDB files. If those files are not generated then the install
|
|
utility will fail because those PDB files are not found. An optional
|
|
variable, DISABLE_PDB_FILES, was added to not install PDB files.
|
|
|
|
(ADB - 2019/07/17, HDFFV-10424)
|
|
|
|
- Add mingw CMake support with a toolchain file
|
|
|
|
There has been a number of mingw issues that has been linked under
|
|
HDFFV-10845. It has been decided to implement the CMake cross-compiling
|
|
technique of toolchain files. We will use a linux platform with the mingw
|
|
compiler stack for testing. Only the C language is fully supported, and
|
|
the error tests are skipped. The C++ language works for static but shared
|
|
builds has a shared library issue with the mingw Standard Exception Handling
|
|
library, which is not available on Windows. Fortran has a common cross-compile
|
|
problem with the fortran configure tests.
|
|
|
|
(ADB - 2019/07/12, HDFFV-10845, HDFFV-10595)
|
|
|
|
- Windows PDB files are installed incorrectly
|
|
|
|
For static builds, the PDB files for windows should be installed next
|
|
to the static libraries in the lib folder. Also the debug versions of
|
|
libraries and PDB files are now correctly built using the default
|
|
CMAKE_DEBUG_POSTFIX setting.
|
|
|
|
(ADB - 2019/07/09, HDFFV-10581)
|
|
|
|
- Add option to build only shared libs
|
|
|
|
A request was made to prevent building static libraries and only build
|
|
shared. A new option was added to CMake, ONLY_SHARED_LIBS, which will
|
|
skip building static libraries. Certain utility functions will build with
|
|
static libs but are not published. Tests are adjusted to use the correct
|
|
libraries depending on SHARED/STATIC settings.
|
|
|
|
(ADB - 2019/06/12, HDFFV-10805)
|
|
|
|
- Add options to enable or disable building tools and tests
|
|
|
|
Configure options --enable-tests and --enable-tools were added for
|
|
autotools configure. These options are enabled by default, and can be
|
|
disabled with either --disable-tests (or tools) or --enable-tests=no
|
|
(or --enable-tools=no). Build time is reduced ~20% when tools are
|
|
disabled, 35% when tests are disabled, 45% when both are disabled.
|
|
Reenabling them after the initial build requires running configure
|
|
again with the option(s) enabled.
|
|
|
|
(LRK - 2019/06/12, HDFFV-9976)
|
|
|
|
- Change tools test that test the error stack
|
|
|
|
There are some use cases which can cause the error stack of tools to be
|
|
different then the expected output. These tests now use grepTest.cmake,
|
|
this was changed to allow the error file to be searched for an expected string.
|
|
|
|
(ADB - 2019/04/15, HDFFV-10741)
|
|
|
|
- Keep stderr and stdout separate in tests
|
|
|
|
Changed test handling of output capture. Tests now keep the stderr
|
|
output separate from the stdout output. It is up to the test to decide
|
|
which output to check against a reference. Also added the option
|
|
to grep for a string in either output.
|
|
|
|
(ADB - 2018/12/12, HDFFV-10632)
|
|
|
|
- Add toolchain and cross-compile support
|
|
|
|
Added info on using a toolchain file to INSTALL_CMAKE.txt. A
|
|
toolchain file is also used in cross-compiling, which requires
|
|
CMAKE_CROSSCOMPILING_EMULATOR to be set. To help with cross-compiling
|
|
the fortran configure process, the HDF5UseFortran.cmake file macros
|
|
were improved. Fixed a Fortran configure file issue that incorrectly
|
|
used #cmakedefine instead of #define.
|
|
|
|
(ADB - 2018/10/04, HDFFV-10594)
|
|
|
|
- Add warning flags for Intel compilers
|
|
|
|
Identified Intel compiler specific warnings flags that should be used
|
|
instead of GNU flags.
|
|
|
|
(ADB - 2018/10/04, TRILABS-21)
|
|
|
|
- Add default rpath to targets
|
|
|
|
Default rpaths should be set in shared executables and
|
|
libraries to allow the use of loading dependent libraries
|
|
without requiring LD_LIBRARY_PATH to be set. The default
|
|
path should be relative using @rpath on osx and $ORIGIN
|
|
on linux. Windows is not affected.
|
|
|
|
(ADB - 2018/09/26, HDFFV-10594)
|
|
|
|
- Add missing USE_110_API_DEFAULT option.
|
|
|
|
Option USE_110_API_DEFAULT sets the default version of
|
|
versioned APIs. The bin/makevers perl script did not set
|
|
the maxidx variable correctly when the 1.10 branch was
|
|
created. This caused the versioning process to always use
|
|
the latest version of any API.
|
|
|
|
(ADB - 2018/08/17, HDFFV-10552)
|
|
|
|
- Added configuration checks for the following MPI functions:
|
|
|
|
MPI_Mprobe - Used for the Parallel Compression feature
|
|
MPI_Imrecv - Used for the Parallel Compression feature
|
|
|
|
MPI_Get_elements_x - Used for the "big Parallel I/O" feature
|
|
MPI_Type_size_x - Used for the "big Parallel I/O" feature
|
|
|
|
(JTH - 2018/08/02, HDFFV-10512)
|
|
|
|
- Added section to the libhdf5.settings file to indicate
|
|
the status of the Parallel Compression and "big Parallel I/O"
|
|
features.
|
|
|
|
(JTH - 2018/08/02, HDFFV-10512)
|
|
|
|
- Add option to execute swmr shell scripts from CMake.
|
|
|
|
Option TEST_SHELL_SCRIPTS redirects processing into a
|
|
separate ShellTests.cmake file for UNIX types. The tests
|
|
execute the shell scripts if a SH program is found.
|
|
|
|
(ADB - 2018/07/16)
|
|
|
|
|
|
Library:
|
|
--------
|
|
- Add new H5R_ref_t type for object, dataset region and _attribute_
|
|
references. This new type will deprecate the current hobj_ref_t
|
|
and hdset_reg_ref_t types for references. Added H5T_REF datatype
|
|
to read and write new reference types. As opposed to previous
|
|
reference types, reference creation no longer modifies existing
|
|
files. New reference types also now support references to external
|
|
files.
|
|
|
|
(JS - 2019/10/08)
|
|
|
|
- Add S3 and HDFS VFDs to HDF5 maintenance
|
|
|
|
Fix windows requirements and java tests. Windows requires CMake 3.13.
|
|
Install openssl library (with dev files);
|
|
from "Shining Light Productions". msi package preferred.
|
|
|
|
PATH should have been updated with the installation dir.
|
|
set ENV variable OPENSSL_ROOT_DIR to the installation dir.
|
|
set ENV variable OPENSSL_CONF to the cfg file, likely %OPENSSL_ROOT_DIR%\bin\openssl.cfg
|
|
Install libcurl library (with dev files);
|
|
download the latest released version using git: https://github.com/curl/curl.git
|
|
|
|
Open a Visual Studio Command prompt
|
|
change to the libcurl root folder
|
|
run the "buildconf.bat" batch file
|
|
change to the winbuild directory
|
|
nmake /f Makefile.vc mode=dll MACHINE=x64
|
|
copy libcurl-vc-x64-release-dll-ipv6-sspi-winssl dir to C:\curl (installation dir)
|
|
set ENV variable CURL_ROOT to C:\curl (installation dir)
|
|
update PATH ENV variable to %CURL_ROOT%\bin (installation bin dir).
|
|
the aws credentials file should be in %USERPROFILE%\.aws folder
|
|
set the ENV variable "HDF5_ROS3_TEST_BUCKET_URL=https://s3.us-east-2.amazonaws.com/hdf5ros3"
|
|
|
|
(ADB - 2019/09/12, HDFFV-10854)
|
|
|
|
- Added new chunk query functions
|
|
|
|
The following public functions were added to discover information about
|
|
the chunks in an HDF5 file.
|
|
herr_t H5Dget_num_chunks(dset_id, fspace_id, *nchunks)
|
|
herr_t H5Dget_chunk_info_by_coord(dset_id, *coord, *filter_mask, *addr, *size)
|
|
herr_t H5Dget_chunk_info(dset_id, fspace_id, index, *coord, *filter_mask, *addr, *size)
|
|
|
|
(BMR - 2019/06/11, HDFFV-10677)
|
|
|
|
- Improved the performance of virtual dataset I/O
|
|
|
|
Refactored the internal dataspace routines used by the virtual dataset
|
|
code to improve performance, especially when one of the selections
|
|
involved is very long and non-contiguous.
|
|
|
|
(NAF - 2019/05/31, HDFFV-10693)
|
|
|
|
- Added the ability to open files with UTF-8 file names on Windows.
|
|
|
|
The POSIX open(2) API call on Windows is limited to ASCII
|
|
file names. The library has been updated to convert incoming file
|
|
names to UTF-16 (via MultiByteToWideChar(CP_UTF8, ...) and use
|
|
_wopen() instead.
|
|
|
|
(DER - 2019/03/15, HDFFV-2714, HDFFV-3914, HDFFV-3895, HDFFV-8237, HDFFV-10413, HDFFV-10691)
|
|
|
|
- Add new API H5M for map objects. Currently not supported by native
|
|
library, can be supported by VOL connectors.
|
|
|
|
(NAF - 2019/03/01)
|
|
|
|
- Remove H5I_REFERENCE from the library
|
|
|
|
This ID class was never used by the library and has been removed.
|
|
|
|
(DER - 2018/12/08, HDFFV-10252)
|
|
|
|
- Allow pre-generated H5Tinit.c and H5make_libsettings.c to be used.
|
|
|
|
Rather than always running H5detect and generating H5Tinit.c and
|
|
H5make_libsettings.c, supply a location for those files.
|
|
|
|
(ADB - 2018/09/18, HDFFV-10332)
|
|
|
|
|
|
Parallel Library:
|
|
-----------------
|
|
- Changed the default behavior in parallel when reading the same dataset in its entirely
|
|
(i.e. H5S_ALL dataset selection) which is being read by all the processes collectively.
|
|
The dataset mush be contiguous, less than 2GB, and of an atomic datatype.
|
|
The new behavior is the HDF5 library will use an MPI_Bcast to pass the data read from
|
|
the disk by the root process to the remain processes in the MPI communicator associated
|
|
with the HDF5 file.
|
|
|
|
(MSB - 2019/01/02, HDFFV-10652)
|
|
|
|
Fortran Library:
|
|
----------------
|
|
- Added new Fortran derived type, c_h5o_info_t, which is interoperable with
|
|
C's h5o_info_t. This is needed for callback functions which
|
|
pass C's h5o_info_t data type definition.
|
|
|
|
(MSB, 2019/01/08, HDFFV-10443)
|
|
|
|
- Added new Fortran API, H5gmtime, which converts (C) 'time_t' structure
|
|
to Fortran DATE AND TIME storage format.
|
|
|
|
(MSB, 2019/01/08, HDFFV-10443)
|
|
|
|
- Added new Fortran 'fields' optional parameter to: h5ovisit_f, h5oget_info_by_name_f,
|
|
h5oget_info, h5oget_info_by_idx and h5ovisit_by_name_f.
|
|
|
|
(MSB, 2019/01/08, HDFFV-10443)
|
|
|
|
C++ Library:
|
|
------------
|
|
- Added new wrappers for H5Pset/get_create_intermediate_group()
|
|
LinkCreatPropList::setCreateIntermediateGroup()
|
|
LinkCreatPropList::getCreateIntermediateGroup()
|
|
|
|
(BMR - 2019/04/22, HDFFV-10622)
|
|
|
|
- Added new wrapper for H5Ovisit2()
|
|
H5Object::visit()
|
|
|
|
(BMR - 2019/02/14, HDFFV-10532)
|
|
|
|
|
|
Java Library:
|
|
----------------
|
|
- Fix a failure in JUnit-TestH5P on 32-bit architectures
|
|
|
|
(JTH - 2019/04/30)
|
|
|
|
- Duplicate the data read/write functions of Datasets for Attributes.
|
|
|
|
Region references could not be displayed for attributes as they could
|
|
for datasets. Datasets had overloaded read and write functions for different
|
|
datatypes that were not available for attributes. After adding similar
|
|
functions, attribute region references work normally.
|
|
|
|
(ADB - 2018/12/12, HDFVIEW-4)
|
|
|
|
- Removed H5I_REFERENCE from the Java wrappers
|
|
|
|
This ID class was never used by the library and has been removed
|
|
from the Java wrappers.
|
|
|
|
(DER - 2018/12/08, HDFFV-10252)
|
|
|
|
|
|
Tools:
|
|
------
|
|
- h5repack was fixed to repack datasets with external storage
|
|
to other types of storage.
|
|
|
|
New test added to repack files and verify the correct data using h5diff.
|
|
|
|
(JS - 2019/09/25, HDFFV-10408)
|
|
(ADB - 2019/10/02, HDFFV-10918)
|
|
|
|
- h5dump was fixed for 128-bit floats, but was missing a test.
|
|
|
|
New test greps for the first 15 numbers of the 128-bit value.

Bug Fixes since HDF5-1.10.3 release
|
|
==================================
|
|
|
|
Library
|
|
-------
|
|
- Improved performance when creating a large number of small datasets by
|
|
retrieving default property values from the API context instead of doing
|
|
skip list searches.
|
|
|
|
(CJH - 2019/12/10, HDFFV-10658)
|
|
|
|
- Fixed user-created data access properties not existing in the property list
|
|
returned by H5Dget_access_plist. Thanks to Steven Varga for submitting a
|
|
reproducer and a patch.
|
|
|
|
(CJH - 2019/12/9, HDFFV-10934)
|
|
|
|
- Fixed the iteration error in test_versionbounds() in test/dtypes.c
|
|
|
|
The test was supposed to loop through all valid combinations of
|
|
low and high bounds in the array versions[], but they were set to
|
|
H5F_LIBVER_EARLIEST always without changing.
|
|
|
|
The problem was fixed by indexing low and high into the array versions[].
|
|
|
|
(VC - 2019/09/30)
|
|
|
|
- Fixed the slowness of regular hyperslab selection in a chunked dataset
|
|
|
|
It was reported that the selection of every 10th element from a 20G
|
|
chunked dataset was extremely slow and sometimes could hang the system.
|
|
The problem was due to the iteration and the building of the span tree
|
|
for all the selected elements in file space.
|
|
|
|
As the selected elements are going to a 1-d contiguous single block
|
|
memory space, the problem was fixed by building regular hyperslab selections
|
|
in memory space for the selected elements in file space.
|
|
|
|
(VC - 2019/09/26, HDFFV-10585)
|
|
|
|
- Fixed a bug caused by bad tag value when condensing object header
|
|
messages
|
|
|
|
There was an assertion failure when moving messages from running a
|
|
user test program with library release hdf5.1.10.4. It was because
|
|
the tag value (object header's address) was not set up when entering
|
|
the library routine H5O__chunk_update_idx(), which will eventually
|
|
verifies the metadata tag value when protecting the object header.
|
|
|
|
The problem was fixed by replacing FUNC_ENTER_PACKAGE in H5O__chunk_update_idx()
|
|
with FUNC_ENTER_PACKAGE_TAG(oh->cache_info.addr) to set up the metadata tag.
|
|
|
|
(VC - 2019/08/23, HDFFV-10873)
|
|
|
|
- Fixed the test failure from test_metadata_read_retry_info() in
|
|
test/swmr.c
|
|
|
|
The test failure is due to the incorrect number of bins returned for
|
|
retry info (info.nbins). The # of bins expected for 101 read attempts
|
|
is 3 instead of 2. The routine H5F_set_retries() in src/H5Fint.c
|
|
calculates the # of bins by first obtaining the log10 value for
|
|
(read attempts - 1). For PGI/19, the log10 value for 100 read attempts
|
|
is 1.9999999999999998 instead of 2.00000. When casting the log10 value
|
|
to unsigned later on, the decimal part is chopped off causing the test
|
|
failure.
|
|
|
|
This was fixed by obtaining the rounded integer value (HDceil) for the
|
|
log10 value of read attempts first before casting the result to unsigned.
|
|
|
|
(VC - 2019/8/14, HDFFV-10813)
|
|
|
|
- Fixed an issue where creating a file with non-default file space info
|
|
together with library high bound setting to H5F_LIBVER_V18.
|
|
|
|
When setting non-default file space info in fcpl via
|
|
H5Pset_file_space_strategy() and then creating a file with
|
|
both high and low library bounds set to
|
|
H5F_LIBVER_V18 in fapl, the library succeeds in creating the file.
|
|
File creation should fail because the feature of setting non-default
|
|
file space info does not exist in library release 1.8 or earlier.
|
|
|
|
This was fixed by setting and checking the proper version in the
|
|
file space info message based on the library low and high bounds
|
|
when creating and opening the HDF5 file.
|
|
|
|
(VC - 2019/6/25, HDFFV-10808)
|
|
|
|
- When iterating over an old-style group (i.e., when not using the latest
|
|
file format) of size 0, a NULL pointer representing the empty links
|
|
table would be sent to qsort(3) for sorting, which is undefined behavior.
|
|
|
|
Iterating over an empty group is explicitly tested in the links test.
|
|
This has not caused any failures to date and was flagged by gcc's
|
|
-fsanitize=undefined.
|
|
|
|
The library no longer attempts to sort an empty array.
|
|
|
|
(DER - 2019/06/18, HDFFV-10829)
|
|
|
|
- Fixed an issue where copying a version 1.8 dataset between files using
|
|
H5Ocopy fails due to an incompatible fill version
|
|
|
|
When using the HDF5 1.10.x H5Ocopy() API call to copy a version 1.8
|
|
dataset to a file created with both high and low library bounds set to
|
|
H5F_LIBVER_V18, the H5Ocopy() call will fail with the error stack indicating
|
|
that the fill value version is out of bounds.
|
|
|
|
This was fixed by changing the fill value message version to H5O_FILL_VERSION_3
|
|
(from H5O_FILL_VERSION_2) for H5F_LIBVER_V18.
|
|
|
|
(VC - 2019/6/14, HDFFV-10800)
|
|
|
|
- Some oversights in the index iterating area of the library caused
|
|
a callback function to continue iterating even though it's supposed
|

- Fix hangs with collective metadata reads during chunked dataset I/O
|
|
|
|
In the parallel library, it was discovered that when a particular
|
|
sequence of operations following a pattern of:
|
|
|
|
"write to chunked dataset" -> "flush file" -> "read from dataset"
|
|
|
|
occurred with collective metadata reads enabled, hangs could be
|
|
observed due to certain MPI ranks not participating in the collective
|
|
metadata reads.
|
|
|
|
To fix the issue, collective metadata reads are now disabled during
|
|
chunked dataset raw data I/O.

When deleting the attribute nodes from the name index v2 B-tree,

(ADB - 2018/09/05, HDFFV-9059)
|
|
|
|
- A bug was discovered in the parallel library where an application
|
|
would hang if a collective read/write of a chunked dataset occurred
|
|
when collective metadata reads were enabled and some of the ranks
|
|
had no selection in the dataset's dataspace. The ranks which had no
|
|
selection in the dataset's dataspace called H5D__chunk_addrmap() to
|
|
retrieve the lowest chunk address in the dataset. This is because we
|
|
require reads/writes to be performed in strictly non-decreasing order
|
|
of chunk address in the file.
|
|
|
|
When the chunk index used was a version 1 or 2 B-tree, these
|
|
non-participating ranks would issue a collective MPI_Bcast() call
|
|
that the participating ranks would not issue, causing the hang. Since
|
|
the non-participating ranks are not actually reading/writing anything,
|
|
the H5D__chunk_addrmap() call can be safely removed and the address used
|
|
for the read/write can be set to an arbitrary number (0 was chosen).

- fcntl(2)-based file locking incorrectly passed the lock argument struct
|
|
instead of a pointer to the struct, causing errors on systems where
|
|
flock(2) is not available.
|
|
|
|
File locking is used when files are opened to enforce SWMR semantics. A
|
|
lock operation takes place on all file opens unless the
|
|
HDF5_USE_FILE_LOCKING environment variable is set to the string "FALSE".
|
|
flock(2) is preferentially used, with fcntl(2) locks as a backup if
|
|
flock(2) is unavailable on a system (if neither is available, the lock
|
|
operation fails). On these systems, the file lock will often fail, which
|
|
causes HDF5 to not open the file and report an error.
|
|
|
|
This bug only affects POSIX systems. Win32 builds on Windows use a no-op
|
|
locking call which always succeeds. Systems which exhibit this bug will
|
|
have H5_HAVE_FCNTL defined but not H5_HAVE_FLOCK in the configure output.
|
|
|
|
This bug affects HDF5 1.10.0 through 1.10.5.
|
|
|
|
fcntl(2)-based file locking now correctly passes the struct pointer.

|
|
|
|
Created two local class variables to hold the values obtained during

|
|
the class values rather then calling the native functions.
|
|
The native functions were renamed and called only during execution

MPI-3 functions in the Parallel Compression and "big Parallel I/O"

|
|
step would pass but the build itself would fail when it could not
|
|
locate the MPI-3 functions used.
|
|
|
|
As a result of these new checks, HDF5 can again be built with MPI-2,
|
|
but the Parallel Compression feature will be disabled as it relies
|
|
on the MPI-3 functions used.

The bug was not caught during testing because all of the current

- A bug was discovered in the parallel library which caused parallel

writes of filtered datasets to trigger an assertion failure in the

|
file free space manager.
|
|
|
|
This occurred when the filter used caused chunks to repeatedly shrink
|
|
and grow over the course of several dataset writes. The previous chunk
|
|
information, such as the size of the chunk and the offset in the file,
|
|
was being cached and not updated after each write, causing the next write

to the chunk to retrieve the incorrect cached information and run into

issues when reallocating space in the file for the chunk.

- A bug was discovered in the parallel library which caused the

H5D__mpio_array_gatherv() function to allocate too much memory.
|
|
|
|
When the function is called with the 'allgather' parameter set
|
|
to a non-true value, the function will receive data from all MPI
|
|
ranks and gather it to the single rank specified by the 'root'
|
|
parameter. However, the bug in the function caused memory for
|
|
the received data to be allocated on all MPI ranks, not just the
|
|
singular rank specified as the receiver. In some circumstances,
|
|
this would cause an application to fail due to the large amounts
|
|
of memory being allocated.

Known Problems
|
|
==============
|
|
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.
|
|
ADB - 2019/05/07
|
|
|
|
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.
|
|
|
|
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.
