Question

I am trying to install ONIPY on ubuntu 11.10. I am using python 2.7. After modifying (I replaced python2.6 with python2.7) the makefile and installing it I can’t import the wrapper library.

ERROR:

>>> import OpenNIPythonWrapper

Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
ImportError: /usr/lib/pymodules/python2.7/OpenNIPythonWrapper.so: undefined symbol: _ZNK5boost6python7objects21py_function_impl_base9max_arityEv

Answer 1

I fixed it after trying some modifications on the makefile. So changes are as follows…

BEFORE :

$(TARGET): $(OBJ)
    $(CXX) -fPIC -shared -Wl,--export-dynamic $(LIBS) -o $@ $^ 

AFTER:

$(TARGET): $(OBJ)
    $(CXX) -fPIC -shared -Wl,-soname,OpenNIPythonWrapper.so -o $@ $^ $(LIBS)
