-------
|
|
|
|
* Fixed bug with contiguous hyperslabs not being detected, causing
|
|
|
|
slower I/O than necessary.
|
|
|
|
* Fixed bug where non-aligned hyperslab I/O on chunked datasets was
|
|
|
|
causing errors during I/O
|
|
|
|
* The RCSID string in H5public.h was causing the C++ compiling problem
|
|
|
|
because when it was included multiple times, C++ did not like multiple
|
|
|
|
definitions of the same static variable. All occurance of RCSID
|
|
|
|
definition are removed since we have not used it consistently before.

Configuration
|
|
|
|
-------------
|
|
|
|
* Changed the default value of $NPROCS from 2 to 3 since 3 processes
|
|
|
|
have a much bigger chance catching parallel errors than just 2.

Known Problems

2000-03-24 05:34:06 +08:00
|
|
|
==============
|
|
|
|
|
2001-02-21 03:35:07 +08:00
|
|
|
* The stream-vfd test uses ip port 10007 for testing. If another application
|
|
|
|
is already using that port address, the test will hang indefinitely and
|
|
|
|
has to be terminated by the kill command. To try the test again, change
|
|
|
|
the port address in test/stream_test.c to one not being used in the host.
|
|
|
|
|
2001-02-01 01:28:57 +08:00
|
|
|
* The --enable-static-exec configure flag fails to compile for Solaris
|
|
|
|
platforms. This is due to the fact that not all of the system
|
|
|
|
libraries on Solaris are available in a static format.
|
|
|
|
|
|
|
|
The --enable-static-exec configure flag also fails to correctly compile
|
|
|
|
on Linux platforms using the gcc-2.95.2 compiler.
|
|
|
|
|
2001-02-21 03:35:07 +08:00
|
|
|
The --enable-static-exec configure flag also fails to correctly compile
|
|
|
|
on IBM SP2 platform for the serial mode. The parallel mode works fine
|
|
|
|
with this option.
|
|
|
|
|
2001-02-01 01:28:57 +08:00
|
|
|
It is suggested that you don't use this option on these platforms
|
|
|
|
during configuration.
|
|
|
|
|
2001-01-19 05:11:33 +08:00
|
|
|
* With the gcc 2.95.2 compiler, HDF 5 uses the `-ansi' flag during
|
|
|
|
compilation. The ANSI version of the compiler complains about not being
|
|
|
|
able to handle the `long long' datatype with the warning:
|
2001-01-12 06:47:33 +08:00
|
|
|
|
2001-01-19 05:11:33 +08:00
|
|
|
warning: ANSI C does not support `long long'
|
|
|
|
|
|
|
|
This warning is innocuous and can be safely ignored.
|
2001-01-12 06:47:33 +08:00
|
|
|
|
2000-12-19 06:06:13 +08:00
|
|
|
* SunOS 5.6 with C WorkShop Compilers 4.2: Hyperslab selections will
|
2000-03-24 05:34:06 +08:00
|
|
|
fail if library is compiled using optimization of any level.
|
2000-02-10 05:36:37 +08:00
|
|
|
|
2001-02-03 03:38:13 +08:00
|
|
|
* When building hdf5 tools and applications on windows platform, a linking
|
2001-02-09 01:03:03 +08:00
|
|
|
warning: defaultlib "LIBC" conflicts with use of other libs will appear
|
|
|
|
on debug version when running VC++6.0. This warning doesn't affect building
|
2001-02-10 06:37:18 +08:00
|
|
|
and testing hdf5 applications. We will continue investigating this.
|
|
|
|
|
|
|
|
* h5toh4 converter fails two cases(tstr.h5 and tmany.h5) for release dll version on
|
2001-02-20 03:37:14 +08:00
|
|
|
windows 2000 and NT. The reason is possibly due to windows NT DLL
|
|
|
|
convention on freeing memory. It seems that memory cannot be free
|
|
|
|
across library or DLL. It is still under investigated.
|
2001-02-10 06:37:18 +08:00
|
|
|
|
2000-12-19 06:06:13 +08:00
|
|
|
* The Stream VFD was not tested yet under Windows.
|
|
|
|
It is not supported in the TFLOPS machine.
|
|
|
|
|
2000-12-22 00:17:05 +08:00
|
|
|
* Shared library option is broken for IBM SP and some Origin 2000 platforms.
|
|
|
|
One needs to run ./configure with '--disable-shared'
|
2000-12-19 06:06:13 +08:00
|
|
|
|
|
|
|
* The ./dsets tests failed in the TFLOPS machine if the test program,
|
|
|
|
dsets.c, is compiled with the -O option. The hdf5 library still works
|
2000-12-20 01:44:28 +08:00
|
|
|
correctly with the -O option. The test program works fine if it is
|
|
|
|
compiled with -O1 or -O0. Only -O (same as -O2) causes the test
|
|
|
|
program to fail.
|
2000-12-20 00:08:47 +08:00
|
|
|
|
|
|
|
* Certain platforms give false negatives when testing h5ls:
|
|
|
|
- Solaris x86 2.5.1, Cray T3E and Cray J90 give errors during testing
|
|
|
|
when displaying object references in certain files. These are benign
|
|
|
|
differences due to the difference in sizes of the objects created on
|
|
|
|
those platforms. h5ls appears to be dumping object references
|
|
|
|
correctly.
|
|
|
|
- Cray J90 (and Cray T3E?) give errors during testing when displaying
|
|
|
|
some floating-point values. These are benign differences due to the
|
|
|
|
different precision in the values displayed and h5ls appears to be
|
|
|
|
dumping floating-point numbers correctly.
|
2001-01-30 06:52:32 +08:00
|
|
|
|
|
|
|
* Before building HDF5 F90 Library from source on Crays (T3E and J90)
|
|
|
|
replace H5Aff.f90, H5Dff.f90 and H5Pff.f90 files in the fortran/src subdirectory
|
|
|
|
in the top level directory with the Cray-specific files from the
|
|
|
|
ftp://hdf.ncsa.uiuc.edu/pub/ougoing/hdf5/hdf5-1.4.0-beta/F90_source_for_Crays
|
|
|
|
directory.
|
2001-02-10 01:39:16 +08:00
|
|
|
|
|
|
|
* The h4toh5 utility produces images that do not correctly conform
|
|
|
|
to the HDF5 Image and Palette Specification.

Several required HDF5 attributes are omitted, and the dataspace

is reversed (i.e., the ht. and width of the image dataset is

incorrectly described.) For more information, please see:
