I have a CMakeLists.txt for both SZip and Zip.
Can we just integrate both SZip and Zip sources into the HDF5 sources?
Would make configuration much easier. Or is there license issues with that.SZIP (http://www.hdfgroup.org/doc_resource/SZIP/) has some restrictions.

John and All,I had some discussions today with the Windows support team here. We
agreed that we should try Cmake for Windows. Cmake looks very powerful, and
we also think it will address some of the issues we are dealing with in our
daily regression testing of multiple Windows configurations.If Cmake works (and it looks like from the discussions here, it should),
we will be willing to incorporate Cmake with HDF5 and support it for Windows
(and get rid of our current infrastructure for Windows). It would be great
if we can work with the community to support Cmake/HDF5 on other systems.
But looking into support beyond Windows is little-bit premature at this
point; we have to evaluate it first. Your help will be highly appreciated.On Nov 17, 2009, at 2:47 AM, Biddiscombe, John A. wrote:
I’m prepared to volunteer to help and I will be happy to setup an svn
repository and a TWiki page for Hdf5-Cmake. I can start with Solomon’s
generous contribution and get working on a more robust cmakeified hdf5. I
can test it with ParaView/Xdmf on linux, windows (including intel
C++/fortran 11.x), and Cray XT5. I suspect the cmake cross compilation on
HPC machines may be the trickiest to get smoothly working. (Though my
success in the past with CMake+Intel fortran on windows has been ‘poor’ at
best)The proposal looks great. If we can get, for example, 1.8.4 code with
Cmake that works for Windows (let's start with MSVS and Cygwin; HDF5 C, some
tests for C library and command line utilities (can be just h5dump and
h5diff for the first try), it will be very helpful. We will also need SZIP
port to Cmake (Solomin has it for his software, can it be given back to us?
For SZIP, I can go ahead and add Cmake files to SVN right away).Thank you,
Elena
P.S. Does anyone has experience with Cmake on Alpha OpenVMS?
Does it
work there? (probably too good to be trueIf the HDF group give their blessing and adopt cmake in the future, I’ll
be a happy bunny. I probably can’t help with the myriad other tools that the
HDF group are supporting, but basic lib functionality shouldn’t be a
problem.JB

By rudimentary, I mean that it has only ever been tested on Windows/VS
and it does not perform all of the configuration tasks. In particular, the
architecture detection code in H5Detect is not run.If you are interested in looking at it or using it as a starting point,
my SVN tree is visible on Google Code:
http://code.google.com/p/permafrost/source/browse/The project itself is BSD licensed, but I'm willing to donate anything

What if one of _our_ paying customers has requested it and we went
forward creating the CMake build system for HDF5 1.8.x. Would the HDF Group
give their backing? By that I mean, is it possible to get CVS read/write
access to the HDF5 source codes?
How willing is the HDF5 group to make some small tweaks to the HDF5
source codes to accommodate CMake if it were needed? I would much rather go
down the road of creating a CMake version of HDF5 _if_ I had the official
backing of the HDF5 group, rather than "forking" the code base and putting
it up on another server. My goal is NOT to cause any type of rift in the
HDF5 community but I am curios what The HDF Group's position is on this?As I mentioned in my previous email, we do consider Cmake as one of the
possible build systems for the HDF software. Since no one in our group has
expertise in Cmake, it is very hard for us to give an answer because of many
things we do not know.As you all probably aware, build system for HDF (and I am talking here
not only about HDF5 but HDF4, h4toh5, HDF Java products, etc.) has to work
on many platforms and in many environments (some are listed below plus some
unique platforms we support at the National Labs and other places), has to
support Fortran(77,90,2003), C++, and Java, has to work well with MPI I/O,
support shared libraries, support statically linked binaries, support
universal binariesfor Mac, support cross-compilation, etc. To keep our
maintenance cost low, we cannot consider only moving HDF5 to Cmake, but need
to think about other software we support and implication of this move on
other packages that depend on HDF (may be none, I simply do not know)Said this, we will be more than happy to work with the community on
evaluating Cmake capability for HDF5. One of the platforms that desperately
needs improvements for the build process is Windows. If we can make Cmake to
work on Windows forMSVS compilers+ Intel Fortran compilers + SZLIB + provide static
libraries and DLLs
Cygwin
MinGWit will be worth adding it to HDF5. (Do I contradict myself
Bottom line:
We will be glad to work with someone (Mike? as we planned?) to evaluate
Cmake for HDF5; we would like to target Windows platforms first. After we
finish evaluation, we will be able to answer many questions your raised in
this email.Thank you!
Elena
Also, what are the HDF Groups requirements as in Operating Systems that
need to be verified/working? What testing infrastructure is needed? (MPI,
Cluster, PCs, Macs, Linux, Solaris.. )I am guessing that Kitware would be willing to host a "Dashboard" for
HDF5 so that people can submit test results for their configurations.Guessing, but I am thinking ParaView would be an immediate beneficiary
of the work. I know I have more than a few projects that would benefit.
Others may as well.Thoughts?

And do the hdf group have plans to move to a cmake based build? The
subject has come up once or twice on the list, but I wonder if a decision
has been made.Thanks
