(2) Using mpt and mpich. (3) When configured with static-exec enabled, tests fail in serial mode. (4) No HDF4-related tools. (5) Shared libraries are provided only for the C library. Known Problems ============== * When a dataset with the variable-legth datatype is overwritten, the library can develop memory leaks that cause the file to become unnecessarily large. This is planned to be fixed in the next release. * On the SV1, the h5ls test fails due to a difference between the SV1 printf precision and the printf precision on other platforms. * The h5dump tests may fail to match the expected output in some platforms (e.g. SP2 parallel, Windows) where the error messages directed to "stderr" do not appear in the "right order" with output from stdout. This is not an error. * The --enable-static-exec configure flag fails to compile for HP-UX 11.00 platforms. * The executables are always dynamic on IRIX64 6.5(64 and n32) and IRIX 6.5 even if they are configured with --enable-static-exec. * IRIX 6.5 fails to compile if configured with --enable-static-exec. * For 24-bit image conversion from H4->H5, the current conversion is not consistent with HDF5 image specification. * In some cases, and SDS with an UNLIMITED dimension that has not been written (current size = 0) is not converted correctly. * After "make install" or "make install-doc" one may need to reload the source from the tar file before doing another build. * The HDF5_MPI_OPT_TYPES optimization code in the parallel HDF5 will cause a hang in some cases when chunked storage is used. This is now set to be off by default. One may turn it on by setting environment variable HDF5_MPI_OPT_TYPES to a non-zero value such as 1.
