what's the problem...... PyErr_Print() print the error info below: Traceback (most recent call last): File "./myModule111.py", line 3, in ? import base64 File "/usr/lib/python2.3/base64.py", line 7, in ? import binascii ImportError: /usr/lib/python2.3/lib-dynload/binascii.so:
undefined
symbol: PyExc_TypeError
i check the binascii.so, ldd -r binascii.so, this lib really has
many undefined symbols include PyExc_TypeError, but the problem
is
when the program is executable, it can goes fine......
when i compile the program as .so lib, i add -Xlinker -export- dynamic, it doesn't solve the problem.........
Ah, the joys of dynamic linkers...
You'll need to specify the exact version of your operating system
(probably Linux, but maybe MacOSX or some other unix variant?), and,
for completeness, your compiler and linker version.Sometimes symbols in the base executable are available to all
dynamically loaded modules, but symbols in modules that are themselves
loaded dynamically not. This seems to be what's biting you.Oh yes: can you try a newer version of Python? I fixed a similar error
for Python on MacOSX at some point in the past, it could be that
you're looking at an error has been fixed in the mean time, 2.3 ispretty old by now.
