[svn-r6550] Purpose:
To support szip compression in HDF5 Description: szip compression support is required by NASA ESDIS. The compression algorithm is a good compression algorithm for scientific data. In HDF5, we add another filter function to make szip as a default compression package as we did for gzip(or zlib). H5config.in needs to be regenerated by autoheader for SZIP flags. Solution: A new file called H5Zszip.c will be added in the Makefile.in Flags like: HAVE_FILTER_SZIP should be auto-generated by autoheader. Platforms tested: Since there are changes of configure.in and configure,I didn't use h5committest. I tested with four platforms. 1) Linux 2.4 (eirene) 2) Solaris 2.7(arabica) 3) windows 2000(VS 6.0) 4) SGI IRIX6.5-64(modi4) For test 1)-3), only basic C tests were done For modi4 test, I tested 64-bit C,parallel and fortran. All tests passed, except a warning message from szip library when checksum is used in some order, which doesn't cause any real problems. Misc. update:
