Hi,
I am working on a python3 binding of a C++ lib. This lib is installed in
my system but the latest version of this lib introduce several
incompatibilities. So I need to update my python binding.
I'm working into a virtual environment (py370_venv) python-3.7.0 is
installed into ./localpythons/lib/python3.7
So, the paths are:
# python-3.7.0
~/./localpythons/lib/python3.7/
# my binding python -> libexiv2
~/./localpythons/lib/python3.7/site-packages/pyexiv2/*.py
~/./localpythons/lib/python3.7/site-packages/pyexiv2/libexiv2python.cpython-37m-x86_64-linux-gnu.so
# and the latest version of libexiv2
~/CPython/py370_venv/lib/libexiv2.so.0.27.0
All theses path are in the sys.path
Now I test my binding:
>>> import pyexiv2
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
File
"/home/vincent/CPython/py370_venv/lib/python3.7/site-packages/py3exiv2-0.1.0-py3.7-linux-x86_64.egg/pyexiv2/__init__.py",
line 60, in <module>
import libexiv2python
ImportError:
/home/vincent/CPython/py370_venv/lib/python3.7/site-packages/py3exiv2-0.1.0-py3.7-linux-x86_64.egg/libexiv2python.cpython-37m-x86_64-linux-gnu.so:
undefined symbol: _ZN5Exiv27DataBufC1ERKNS_10DataBufRefE
>>>
Checking the libexiv2.so the symbol exists
~/CPython/py370_venv/lib$ objdump -T libexiv2.so.0.27.0
....
000000000012c8d0 g DF .text 000000000000000f Base
_ZN5Exiv27DataBufC1ERKNS_10DataBufRefE
....
But it is not present into my old libexiv2 system, so I presume python use
/usr/lib/x86_64-linux-gnu/libexiv2.so.14.0.0 (The old 0.25) instead of
~/CPython/py370_venv/lib/libexiv2.so.0.27.0 (The latest 0.27)
How can I solve that ?
My sys.path:
['', '/home/vincent/.localpythons/lib/python37.zip',
'/home/vincent/.localpythons/lib/python3.7',
'/home/vincent/.localpythons/lib/python3.7/lib-dynload',
'/home/vincent/CPython/py370_venv/lib/python3.7/site-packages',
'/home/vincent/CPython/py370_venv/lib/python3.7/site-packages/py3exiv2-0.1.0-py3.7-linux-x86_64.egg',
'/home/vincent/CPython/py370_venv/lib/']
Thanks, Vincent
