Known Problems
|
|
==============
|
|
* "make check" fails on CYGWIN when building shared lib files is enabled. The
|
|
default on Cygwin has been changed to disable shared. It can be enabled with
|
|
the --enable-shared configure option but is likely to fail "make check"
|
|
with GCC compilers. (LK -2015/04/16)
|
|
|
|
* CLANG compiler with the options -fcatch-undefined-behavior and -ftrapv
|
|
catches some undefined behavior in the alignment algorithm of the macro DETECT_I
|
|
in H5detect.c (Issue 8147). Since the algorithm is trying to detect the alignment
|
|
of integers, ideally the flag -fcatch-undefined-behavior shouldn't to be used for
|
|
H5detect.c. In the future, we can separate flags for H5detect.c from the rest of
|
|
the library. (SLU - 2013/10/16)
|
|
|
|
* The 5.9 C++ compiler on Sun failed to compile a C++ test ttypes.cpp. It
|
|
complains with this message:
|
|
"/home/hdf5/src/H5Vprivate.h", line 130: Error: __func__ is not defined.
|
|
|
|
The reason is that __func__ is a predefined identifier in C99 standard. The
|
|
HDF5 C library uses it in H5private.h. The test ttypes.cpp includes
|
|
H5private.h (H5Tpkg.h<-H5Fprivate.h<-H5Vprivate.h<-H5private.h). Sun's 5.9
|
|
C++ compiler doesn't support __func__, thus fails to compile the C++ test.
|
|
But 5.11 C++ compiler does. To check whether your Sun C++ compiler knows this
|
|
identifier, try to compile the following simple C++ program:
|
|
#include<stdio.h>
|
|
|
|
int main(void)
|
|
{
|
|
printf("%s\n", __func__);
|
|
return 0;
|
|
}
|
|
(SLU - 2012/11/5)
|
|
|
|
* The C++ and FORTRAN bindings are not currently working on FreeBSD with the
|
|
native release 8.2 compilers (4.2.1), but are working with gcc 4.6 from the
|
|
ports (and probably gcc releases after that).
|
|
(QAK - 2012/10/19)
|
|
|
|
* The data conversion test dt_arith.c has failures (segmentation fault) from
|
|
"long double" to other datatypes during hard conversion when the library
|
|
is built with the default GCC 4.2.1 on Mac Lion system. It only happens
|
|
with optimization (-O3, -O2, and -O1). Some newer versions of GCC do not
|
|
have this problem. Users should disable optimization or try newer version
|
|
of GCC. (Issue 8017. SLU - 2012/6/12)
|
|
|
|
* The data conversion test dt_arith.c fails in "long double" to integer
|
|
conversion on Ubuntu 11.10 (3.0.0.13 kernal) with GCC 4.6.1 if the library
|
|
is built with optimization -O3 or -O2. The older GCC (4.5) or newer kernal
|
|
(3.2.2 on Fedora) doesn't have the problem. Users should lower down the
|
|
optimization level (-O1 or -O0) by defining CFLAGS in the command line of
|
|
"configure" like:
|
|
|
|
CFLAGS=-O1 ./configure
|
|
|
|
It will overwrite the library's default optimization level. (Issue 7829.
|
|
SLU - 2012/2/7)
|
|
|
|
* --with-mpe configure option does not work with Mpich2. AKC - 2011/03/10)
|
|
|
|
* While working on the 1.8.6 release of HDF5, a bug was discovered that can
|
|
occur when reading from a dataset in parallel shortly after it has been
|
|
written to collectively. The issue was exposed by a new test in the parallel
|
|
HDF5 test suite, but had existed before that. We believe the problem lies with
|
|
certain MPI implementations and/or filesystems.
|
|
|
|
We have provided a pure MPI test program, as well as a standalone HDF5
|
|
program, that can be used to determine if this is an issue on your system.
|
|
They should be run across multiple nodes with a varying number of processes.
|
|
These programs can be found at:
|
|
http://www.hdfgroup.org/ftp/HDF5/examples/known_problems/
|
|
|
|
* Parallel mode in AIX will fail some of the testcheck_version.sh tests where
|
|
it treats "exit(134) the same as if process 0 had received an abort signal.
|
|
This is fixed and will be available in the next release. AKC - 2009/11/3
|
|
|
|
* The PathScale MPI implementation, accessing a Panasas file system, would
|
|
cause H5Fcreate() with H5F_ACC_EXCL to fail even when the file is not
|
|
existing. This is due to the MPI_File_open() call failing if the amode has

|
the MPI_MODE_EXCL bit set. (See bug 1468 for details.) AKC - 2009/8/11
|
|
|
|
* Parallel tests failed with 16 processes with data inconsistency at testphdf5
|
|
/ dataset_readAll. Parallel tests also failed with 32 and 64 processes with
|
|
collective abort of all ranks at t_posix_compliant / allwrite_allread_blocks
|
|
with MPI IO. (CMC - 2009/04/28)
|
|
|
|
* For SNL, spirit/liberty/thunderbird: The serial tests pass but parallel
|
|
tests failed with MPI-IO file locking message. AKC - 2007/6/25.
|
|
* On Intel 64 Linux cluster (RH 4, Linux 2.6.9) with Intel 10.0 compilers use
|
|
-mp -O1 compilation flags to build the libraries. Higher level of optimization
|
|
causes failures in several HDF5 library tests.
|
|
* For HPUX 11.23 many tools tests failed for 64-bit version when linked to the
|
|
shared libraries (tested for 1.8.0-beta2)
|
|
* For SNL, Red Storm: only paralle HDF5 is supported. The serial tests pass
|
|
and the parallel tests also pass with lots of non-fatal error messages.
|
|
* on SUN 5.10 C++ test fails in the "Testing Shared Datatypes with Attributes" test
|
|
* configuring with --enable-debug=all produces compiler errors on most
|
|
platforms. Users who want to run HDF5 in debug mode should use
|
|
--enable-debug rather than --enable-debug=all to enable debugging
|
|
information on most modules.
|
|
* On Mac OS 10.4, test/dt_arith.c has some errors in conversion from long
|
|
double to (unsigned) long long and from (unsigned)long long to long double.
|
|
* On Altix SGI with Intel 9.0 testmeta.c would not compile with -O3
|
|
optimization flag.
|
|
* On VAX, Scaleoffset filter isn't supported. The filter cannot be applied to
|
|
HDF5 data generated on VAX. Scaleoffset filter only supports IEEE standard
|
|
for floating-point data.
|
|
* On Cray X1, a lone colon on the command line of h5dump --xml (as in
|
|
the testh5dumpxml.sh script) is misinterpereted by the operating system
|
|
and causes an error.
|
|
* On mpich 1.2.5 and 1.2.6, we found that if more than two processes
|
|
contribute no IO and the application asks to do IO with collective, we found
|
|
that when using 4 processors, a simple collective write will be hung
|
|
sometimes. This can be verified with t_mpi test under testpar.
|
|
* The dataset created or rewritten with the v1.6.3 library or after can't
|
|
be read with the v1.6.2 library or before when Fletcher32 EDC(filter) is
|
|
enabled. There was a bug in the calculating code of the Fletcher32
|
|
checksum in the library before v1.6.3. The checksum value wasn't consistent
|
|
between big-endian and little-endian systems. This bug was fixed in
|
|
Release 1.6.3. However, after fixing the bug, the checksum value is no
|
|
longer the same as before on little-endian system. The library release
|
|
after 1.6.4 can still read the dataset created or rewritten with the library
|
|
of v1.6.2 or before. SLU - 2005/6/30
|
|
* For the version 6(6.02 and 6.04) of Portland Group compiler on AMD Opteron
|
|
processor, there's a bug in the compiler for optimization(-O2). The library
|
|
failed in several tests but all related to multi driver. The problem has
|
|
been reported to the vendor.
|
|
* On IBM AIX systems, parallel HDF5 mode will fail some tests with error
|
|
messages like "INFO: 0031-XXX ...". This is from the command poe.
|
|
Set the environment variable MP_INFOLEVEL to 0 to minimize the messages
|
|
and run the tests again.
|
|
The tests may fail with messages like "The socket name is already
|
|
in use". HDF5 does not use sockets (except for stream-VFD). This is
|
|
due to problems of the poe command trying to set up the debug socket.
|
|
Check if there are many old /tmp/s.pedb.* staying around. These are
|
|
sockets used by the poe command and left behind due to failed commands.
|
|
Ask your system administrator to clean them out. Lastly, request IBM
|
|
to provide a mean to run poe without the debug socket.
|
|
|
|
* The C++ library's tests fails when compiling with PGI C++ compiler. The
|
|
workaround until the problem is correctly handled is to use the
|
|
flag "--instantiate=local" prior to the configure and build steps, as:
|
|
setenv CXX "pgCC --instantiate=local" for pgCC 5.02 and higher
|
|
|
|
|
|
* 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.
|
|
|
|
* The --enable-static-exec configure flag will only statically link libraries
|
|
if the static version of that library is present. If only the shared version
|
|
of a library exists (i.e., most system libraries on Solaris, AIX, and Mac,
|
|
for example, only have shared versions), the flag should still result in a
|
|
successful compilation, but note that the installed executables will not be
|
|
fully static. Thus, the only guarantee on these systems is that the
|
|
executable is statically linked with just the HDF5 library.
|
|
|
|
* 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:
|
|
|
|
warning: ANSI C does not support `long long'
|
|
|
|
This warning is innocuous and can be safely ignored.
|
|
|
|
* Certain platforms give false negatives when testing h5ls:
|
|
- Cray J90 and Cray T90IEEE 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.
|
|
|
|
* Not all platforms behave correctly with szip's shared libraries. Szip is
|
|
disabled in these cases, and a message is relayed at configure time. Static
|
|
libraries should be working on all systems that support szip, and should be
|
|
used when shared libraries are unavailable. There is also a configure error
|
|
on Altix machines that incorrectly reports when a version of szip without
|
|
an encoder is being used.
|
|
|
|
* On some platforms that use Intel and Absoft compilers to build HDF5 fortran library,
|
|
compilation may fail for fortranlib_test.f90, fflush1.f90 and fflush2.f90
|
|
complaining about exit subroutine. Comment out the line
|
|
IF (total_error .ne. 0) CALL exit (total_error)
|
|
|
|
* Information about building with PGI and Intel compilers is available in
|
|
INSTALL file sections 5.7 and 5.8
|
|
|
|
* On at least one system, (SDSC DataStar), the scheduler (in this case
|
|
LoadLeveler) sends job status updates to standard error when you run
|
|
any executable that was compiled with the parallel compilers.
|
|
|
|
This causes problems when running "make check" on parallel builds, as
|
|
many of the tool tests function by saving the output from test runs,
|
|
and comparing it to an exemplar.
|
|
|
|
The best solution is to reconfigure the target system so it no longer
|
|
inserts the extra text. However, this may not be practical.
|
|
|
|
In such cases, one solution is to "setenv HDF5_Make_Ignore yes" prior to
|
|
the configure and build. This will cause "make check" to continue after
|
|
detecting errors in the tool tests. However, in the case of SDSC DataStar,
|
|
it also leaves you with some 150 "failed" tests to examine by hand.
|
|
|
|
A second solution is to write a script to run serial tests and filter
|
|
out the text added by the scheduler. A sample script used on SDSC
|
|
DataStar is given below, but you will probably have to customize it
|
|
for your installation.
|
|
|
|
Observe that the basic idea is to insert the script as the first item
|
|
on the command line which executes the the test. The script then
|
|
executes the test and filters out the offending text before passing
|
|
it on.
|
|
|
|
#!/bin/csh
|
|
|
|
set STDOUT_FILE=~/bin/serial_filter.stdout
|
|
set STDERR_FILE=~/bin/serial_filter.stderr
|
|
|
|
rm -f $STDOUT_FILE $STDERR_FILE
|
|
|
|
($* > $STDOUT_FILE) >& $STDERR_FILE
|
|
|
|
set RETURN_VALUE=$status
|
|
|
|
cat $STDOUT_FILE
|
|
|
|
tail +3 $STDERR_FILE
|
|
|
|
exit $RETURN_VALUE
|
|
|
|
You get the HDF make files and test scipts to execute your filter script
|
|
by setting the environment variable "RUNSERIAL" to the full path of the
|
|
script prior to running configure for parallel builds. Remember to
|
|
"unsetenv RUNSERIAL" before running configure for a serial build.
|
|
|
|
Note that the RUNSERIAL environment variable exists so that we can
|
|
can prefix serial runs as necessary on the target system. On DataStar,
|
|
no prefix is necessary. However on an MPICH system, the prefix might
|
|
have to be set to something like "/usr/local/mpi/bin/mpirun -np 1" to
|
|
get the serial tests to run at all.
|
|
|
|
In such cases, you will have to include the regular prefix in your
|
|
filter script.

|
* H5Ocopy() does not copy reg_ref attributes correctly when shared-message
|
|
is turn on. The value of the reference in the destination attriubte is
|
|
wrong. This H5Ocopy problem will affect h5copy tool
|
