Some problem when i use Python C/API to embed python script, need Help......
when the program run as exe, everything goes right, but if i compile the program as a .so lib, use other program to load the .so lib and run, it goes wrong,in the lib i also use PyRun_SimpleString("import base64"); it goes wrong.....my python version is 2.3, i want to know 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 is
pretty old by now.

Thank you very much!!I resolved the problem after i install the new version Python(2.6.1).After i installed the new version, i check the binascii.so again, ldd -r binascii.so, everything goes right.... thank you very much.....
