Dear PyTables developers,
I ran into two problems with 64-bit tables-2.2rc1.win-amd64-py2.6.
Pytables and all its dependencies were built from sources using Visual
Studio 2008. There were no build errors. Part of the test_all.py output
is attached.
1) Even though the bzip2 and lzo libraries are present and apparently
linked to the pyd extensions, filters.py claims that those compression
methods are not available.
2) Many (all?) hdf5 file write operations fail during the tests. Dozens
of h5 files are created in the %TEMP% directory before the python
process would eventually crash in hdf5dll.dll.
For comparison, the 32-bit version, tables-2.2rc1.win32-py2.6, built
from exactly the same sources, passes all tests and bzip2 and lzo are
getting used.
I have tried the following without success:
1) using the official HDF5 1.8.4-patch1 libraries and DLLs
2) using a 64 bit pthreads patch from
http://old.nabble.com/Pthreads-64bit-patches-td27399857.html
3) test the binaries on another Windows 7 computer.
I read that the hdf write problem might be due to a zlib/hdf5 version
mismatch. However, the hdf5 binaries test OK and do work with the h5py
and netcdf4 packages.
Any help would be appreciated.
Thank you.

Performing only a light (yet comprehensive) subset of the test suite.
If you want a more complete test, try passing the --heavy flag to this
script
(or set the 'heavy' parameter in case you are using tables.test() call).
The whole suite will take more than 2 minutes to complete on a relatively
modern CPU and around 80 MB of main memory.
