[Swig-user] Swig noob question

[tronix <bha...@gm...>]

Hi all,

http://old.nabble.com/file/p28800490/testincrement.i testincrement.i 
http://old.nabble.com/file/p28800490/testincrement.h testincrement.h 
http://old.nabble.com/file/p28800490/testincrement.cc testincrement.cc 

I'm trying to implement this function which just increments (please find the
source attached) a value in c++. and then using swig trying to get this
python extension. I'm doing this so that I can use swig for my project.
First trying to get to terms with swig. I do not need extensive swig though. 

I used the following commands (referred to many tutorials found upon
googling). 

swig -python -c++ testincrement.i 
g++ -c testincrement.cc testincrement_wrap.cxx -I/usr/include/python2.5
-I/usr/lib/python2.5 -I/usr/include/c++/4.2/
ld -shared -o _testincrement.so testincrement.o testincrement_wrap.o
-lpython2.5

I do this after that in the same directory I start the python shell 
#python
>>import testincrement

This shows the error message :

Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "testincrement.py", line 7, in <module>
    import _testincrement
ImportError: ./_testincrement.so: undefined symbol: _ZNKSs4sizeEv

Please let me know what is the problem here. Any pointers to this problem is
also appreciated.

Thanks
