Package: hdf5-filter-plugin
Version: 0.0~git20221111.49e3b65-2
Severity: serious
Tags: patch
Hello,
hdf5 cannot load the plugin dynamically:
>>> import h5py
>>> h5py.h5z.filter_avail(32004)
False
This is because the library cannot be loaded due to missing HDF5 symbols:
$ python3
Python 3.10.8 (main, Nov 4 2022, 09:21:25) [GCC 12.2.0] on linux
Type "help", "copyright", "credits" or "license" for more information.
>>> import ctypes
>>> lib =
ctypes.CDLL("/usr/lib/x86_64-linux-gnu/hdf5/serial/plugins/libh5lz4.so")
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
File "/usr/lib/python3.10/ctypes/__init__.py", line 374, in __init__
self._handle = _dlopen(self._name, mode)
OSError: /usr/lib/x86_64-linux-gnu/hdf5/serial/plugins/libh5lz4.so:
undefined symbol: H5E_PLINE_g
I filed a PR upstream that fixes the problem:
https://github.com/nexusformat/HDF5-External-Filter-Plugins/pull/27
I'm attaching the corresponding patch.
Thanks,
Enrico
