[request] win32-py2.6 binary release

[dopplershift]

From csi...@gmail.com on October 24, 2009 04:45:23

Please make a python 2.6 build for win32, it would be a great help - I
don't have the time to build it myself but I should install netCDF on
many workstations with activepython 2.6...

Original issue: http://code.google.com/p/netcdf4-python/issues/detail?id=27

I don't have access to a Windows machine to make binary releases for that platform.
The binary 2.5 releases on the download page were contributed by a user, and he is
not ready to install 2.6 yet.

So, the bottom line is that there will be no Python26 windows binary installer until
someone steps up to contribute one.

I can do this. Not now, but I'll try to get that done by next week.

That will be really helpful. Even I am looking for a python 2.6 compatible binary.
Thanks!

There are unofficial binaries at < http://www.lfd.uci.edu/~gohlke/pythonlibs/#netcdf4 >
if you don't mind trying. They were compiled against netcdf 4.1 and numpy 1.4.0.
Unfortunately, they crash during the tst_compound*.py tests.

Christoph: Thanks for making those available. Did you build against HDF 1.8.4? If not,
that would explain the crash on tst_compound*py.

I have compiled netcdf4-python 0.9 (svn), netcdf 4.1 (final), hdf5 1.8.4 (final), and
numpy 1.4.0 from sources using msvc9. The 32 bit netcdf and hdf5 binaries pass all
selftests. When using the netcdf 4.1-rc1 DLL with netcdf4-python 0.9, the compound
tests pass and do not crash.

Is netcdf4-python 0.9 confirmed to work with netcdf 4.1 (final) on other platforms?

Btw, the Win32/MSVC projects were pulled from netcdf 4.1 (final) on the day it was
released...

I've verified svn head passes all tests on macos x and linux x86_64. I

Thanks! Turned out the netcdf 4.1 dll was built with the /MT switch instead of /MD.

Only one serious test failure remains:

ERROR: testing variable slicing

No idea what's causing that one. It's dying trying to create the file. I wonder if it's a
filesystem issue. Is it repeatable (does it always fail on the same test in the same place?
).

[dopplershift]

From cjgoh...@gmail.com on February 08, 2010 20:23:36

OK. There are some other failures of this type that I have also seen in other package
tests:

WindowsError: [Error 32] The process cannot access the file because it is being used
by another process: ...

A 32 bit Windows installer for Python 2.6 is attached. It was compiled against numpy
1.3 (1.4 was pulled today) and is missing opendap support.

Attachment: netCDF4-0.9.win32-py2.6.exe

Thanks! Just curious - how hard would it be to get dap support working on windows?

[dopplershift]

From cjgoh...@gmail.com on February 09, 2010 14:00:33

I guess not too hard. If I understood correctly, the libncdap source is now included
in the netCDF 4.1 release and the only external requirement is libcurl, which is
trivial. Can you confirm this?
However 1) the configure script does not run in a Win32 environment, 2) libncdap was
not included in the MSVC solution provided in rc1, and 3) support for building netcdf
on Windows does not seem to exist.
When I find the time I will try configure netcdf in cygwin with DAP support and build
my own VC project files for libncdap from the configure output.

From whitaker.jeffrey@gmail.com on February 09, 2010 14:56:56

Yes, it is true that libcurl is the only external requirement.

It sounds like it may be quite a bit of work though. Thanks for letting me know. I'll
post your non-dap windows exe on the download site.

Christoph/David: If either of you has time to build a new windows installer for version 0.9.1, built against hdf5
1.8.4-patch1 and netcdf-4.1.1, I would be very grateful.

From cjgoh...@gmail.com on April 08, 2010 12:46:29

I just built new binaries against hdf5 1.8.4-patch1, netcdf-4.1.1 (without DAP), and
numpy 1.4.1rc1: http://www.lfd.uci.edu/~gohlke/pythonlibs/#netcdf4 . These are msvc9
builds. Feel free to test and redistribute the files.

Netcdf-4.1.1 comes without Visual Studio projects. I used the project files from
4.1rc, which still seem to produce working libraries after some small changes.

Test/run_all.py fails the same tests on 32 and 64 bit, mostly due to file access issues:

...EE...........E....EHDF5-DIAG: Error detected in HDF5 (1.8.4-patch1) thread 0:

Christoph: That's great - thanks! David - could you test on windows and see if you get those some file access
errors?
