This is the first check-in message related to szip support at HDF5 1.6 release 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). Solution: In the configure.in and configure, I handled szip exactly the same as what zlib was built into the HDF5. Currently if you don't specify in the configure command line with: ./configure --with-szlib=/..... Unless you put your szip library in your path,you will build the same HDF5 library like before. Also, I only use static szip library to test with HDF5. 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:
HDF5 version 1.5.50 currently under development
Please refer to the release_docs/INSTALL file for installation instructions.
------------------------------------------------------------------------------
This release is almost fully functional for the entire API defined in the
documentation, see the RELEASE.txt file in this directory for information
specific to this release of the library. The INSTALL file contains
instructions on compiling and installing the library. The INSTALL_parallel
file contains instructions on installing the parallel version of the
library. The INSTALL* files can be found in the release_docs/ directory.
Documentation for this release is in the html directory. Start with the
"index.html" in that directory.
Four mailing lists are currently set up for use with the HDF5
library.
hdf5 - For general discussion of the HDF5 library with
other users.
hdf5dev - For discussion of the HDF5 library development
with developers and other interested parties.
hdf5announce - For announcements of HDF5 related developments,
not a discussion list.
hdf5cvs - For checkin notices of code development on the library,
not a discussion list.
To subscribe to a list, send mail to "majordomo@ncsa.uiuc.edu",
with "subscribe <list>" in the _body_, not the Subject, of the message.
E.g., subscribe hdf5
Messages to be sent to the list should be sent to "<list>@ncsa.uiuc.edu".
Nearly daily code snapshots are now being provided at the following URL:
ftp://hdf.ncsa.uiuc.edu/pub/outgoing/hdf5/snapshots
Please read the readme file in that directory before working with a library
snapshot.
