12.5-0 64-bit target on x86-64 Linux -tp shanghai + + +Known Problems +============== +* Several HDF5 command-line tools and tests leave behind generated files + that are not cleaned up with "make clean" or "make distclean" when software + is built in place. The issue will be addressed in the 1.8.13 release. We + recommend to use build directory to compile and test HDF5 as described + in the INSTALL file, section 4.2. + +* Source directory names with spaces in them will cause failures in configure + or make on Mac (HDFFV-8152), Linux, and probably all other platforms. If a + configure command with a space is run from a build directory, it will exit + with an error message: "checking whether build environment is sane... + configure: error: unsafe srcdir value: '/scr/lrknox/hdf5 v1.8.12'". If + configure is run inside or below the directory with the space in the name, + libtool will get the directory path from the system, put the part of the + path before the space in the libdir variable in .../src/libhdf5.la, and + then fail to find the nonexistent directory. This is a known libtool issue + and the suggested workaround is to rename the directory without spaces. + (LRK - 2013/10/22) + +* 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 (HDFFV-8147). This issue will be addressed in the + next release. (SLU - 2013/10/16) + +* Running make check for the tools can fail in the tools tests if make was not + run prior. The tests for the tools use other tools in the tests, therefore + all the tools should be built before testing the tools. (ADB - 2013/10/09) + +* Make provided by Solaris fails in "make check". Solaris users should use + gmake to build and install HDF5 software. (AKC - 2013/10/08 - HDFFV-8534) + +* On OpenVMS, two soft conversion functions (H5T__conv_i_f and H5T__conv_f_i) + have bugs. They convert data between floating-point numbers and integers. + But the library's default is hard conversion. The user should avoid + explicitly enabling soft conversion between floating-point numbers and + integers. (Issue VMS-8; SLU - 2013/09/19) + +* On OpenVMS, ZLIB 1.2.8 library doesn't work properly. ZLIB 1.2.5 works + fine. So please use ZLIB 1.2.5 to build HDF5 library. (Issue VMS-5; + SLU 2013/09/19) + +* When building using the Cray compilers on Cray machines, HDF5 + configure mistakenly thinks the compiler is an intel compiler and + sets the -std=c99 flag which breaks configure on Cray. To build HDF5 + properly on a Cray machine, please consult with the instructions in + INSTALL_parallel for building on Hopper. + (MSC - 2013/04/26 - HDFFV-8429) + +* The h5dump and h5diff utilities occasionally produce different output + between Linux and Windows systems. This is caused by lower-level library + routines that fail to write fill values to the user's buffer when reading + unallocated chunks from datasets that have a fill value set to + H5D_FILL_VALUE_DEFAULT. Due to platform differences the return of + spurious data values has only been encountered on Windows 32-bit systems. + (Issue HDFFV-8247; JP - 2013/03/27) + +* 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 Sun's 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 following h5dump test case fails in BG/P machines (and potentially other + machines that use a command script to launch executables): + + h5dump --no-compact-subset -d "AHFINDERDIRECT::ah_centroid_t[0] it=0 tl=0" + tno-subset.h5 + + This is due to the embedded spaces in the dataset name being interpreted + by the command script launcher as meta-characters, thus passing three + arguments to h5dump's -d flag. The command passes if run by hand, just + not via the test script. + (AKC - 2012/05/03) + +* On hopper, the build failed when RUNSERIAL and RUNPARALLEL are set + to aprun -np X, because the H5lib_settings.c file was not generated + properly. Not setting those environment variables works, because + configure was able to automatically detect that it is a Cray system + and used the proper launch commands when necessary. + (MSC - 2012/04/18) + +* The data conversion test dt_arith.c fails in "long double" to integer + conversion on Ubuntu 11.10 (3.0.0.13 kernel) with GCC 4.6.1 if the library + is built with optimization -O3 or -O2. The older GCC (4.5) or newer kernel + (3.2.2 on Fedora) do not have the problem. Users should lower the + optimization level (-O1 or -O0) by defining CFLAGS in the command line of + "configure" like: + + CFLAGS=-O1 ./configure + + This will overwrite the library's default optimization level. + (SLU - 2012/02/07 - HDFFV-7829) + This issue is no longer present on Ubuntu 12.10 (3.5.0 kernel) with + gcc 4.7.2. + +* The STDIO VFD does not work on some architectures, possibly due to 32/64 + bit or large file issues. The basic STDIO VFD test is known to fail on + 64-bit SunOS 5.10 on SPARC when built with -m64 and 32-bit OS X/Darwin + 10.7.0. The STDIO VFD test has been disabled while we investigate and + a fix should appear in a future release. + (DER - 2011/10/14 - HDFFV-8235) + +* h5diff can report inconsistent results when comparing datasets of enum type + that contain invalid values. This is due to how enum types are handled in + the library and will be addressed in a future release. + (DER - 2011/10/14 - HDFFV-7527) + +* The links test can fail under the stdio VFD due to some issues with external + links. This will be investigated and fixed in a future release. + (DER - 2011/10/14 - HDFFV-7768) + +* After the shared library support was fixed for some bugs, it was discovered + that "make prefix=XXX install" no longer works for shared libraries. It + still works correctly for static libraries. Therefore, if you want to + install the HDF5 shared libraries in a location such as /usr/local/hdf5, + you need to specify the location via the --prefix option during configure + time. E.g, ./configure --prefix=/usr/local/hdf5 ... + (AKC - 2011/05/07 - HDFFV-7583) + +* The parallel test, t_shapesame, in testpar/, may run for a long time and may + be terminated by the alarm signal. If that happens, one can increase the + alarm seconds (default is 1200 seconds = 20 minutes) by setting the + environment variable, $HDF5_ALARM_SECONDS, to a larger value such as 3600 + (60 minutes). Note that the t_shapesame test may fail in some systems + (see the "While working on the 1.8.6 release..." problem below). If + it does, it will waste more time if $HDF5_ALARM_SECONDS is set + to a larger value. + (AKC - 2011/05/07) + +* The C++ and FORTRAN bindings are not currently working on FreeBSD. + (QAK - 2011/04/26) + +* Shared Fortran libraries are not quite working on AIX. While they are + generated when --enable-shared is specified, the fortran and hl/fortran + tests fail. We are looking into the issue. HL and C++ shared libraries + should now be working as intended, however. + (MAM - 2011/04/20) + +* The --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 file systems. + + 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/ + (NAF - 2011/01/19) + +* All the VFL drivers aren't backward compatible. In H5FDpublic.h, the + structure H5FD_class_t changed in 1.8. There is new parameter added to + get_eoa and set_eoa callback functions. A new callback function + get_type_map was added in. The public function H5FDrealloc was taken + out in 1.8. The problem only happens when users define their own driver + for 1.6 and try to plug in 1.8 library. Because there's only one user + complaining about it, we (Elena, Quincey, and I) decided to leave it as + it is (see bug report #1279). Quincey will make a plan for 1.10. + (SLU - 2010/02/02) + +* 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. + (MAM - 2009/11/04) + +* 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) + +* On an Intel 64 Linux cluster (RH 4, Linux 2.6.9) with Intel 10.0 compilers, + use -mp -O1 compilation flags to build the libraries. A higher level of + optimization causes failures in several HDF5 library tests. + +* A dataset created or rewritten with a v1.6.3 library or after cannot be read + with the v1.6.2 library or before when the Fletcher32 EDC filter is enabled. + There was a bug in the calculation of the Fletcher32 checksum in the + library before v1.6.3; the checksum value was not 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 was no longer the same as + before on little-endian system. Library releases after 1.6.4 can still read + datasets created or rewritten with an HDF5 library of v1.6.2 or before. + (SLU - 2005/06/30) + %%%%1.8.11%%%% HDF5 version 1.8.11 released on 2013-05-08 |
