[C++-sig] what do I need to correctly port boost python extensions

[Alexey Akimov]

Hello to everyone,

I get confused trying to port my boost python extension module. So I've made
a shared object file test.so which actually perfectly works in the original
development directory. However, when I copy this file to another Linux
machine (I also copy some extra libraries such as
libboost_python-gcc344-1_39.so.1.39.0 and make sure that both .so files are
in PATH and LD_LIBRARY_PATH) I recieve "Import Error: undefined symbol:
/home/username/bin/libboost_python-gcc34-1_39.so.1.39.0:
PyUnicodeUCS4_FromEncodedObject". I aslo istalled the same version (compared
to one which was used for creation of the module) of Python to the Linux
machine where I try to use my extension.
Can anyone explain me where could the problem be. Also I would clarify what
is the general way to export just created modules? As I understand the order
is following: 1) create .so object (look for it in
/bin/compiler-name/release-or-debug/module-name.so directory) 2) copy this
file as well as other necessary library to some /bin or /lib directory (for
convenience) - and make sure they are in PATH and LD_LIBRARY_PATH variables.
3) import the module in python interpreter.
Do I need to do something else (define some other variables or make some
other changes) in order to make my module work?

Thanks a lot

Alexey
