Ld wrong symbol - c++

Question

I'm buildnig application with boost.python library. I want to link it. Here is the code:
#include <boost/python.hpp>
using namespace boost::python;
// Boost.python definitions to expose classes to Python
BOOST_PYTHON_MODULE(arrayClasses) {
}
And makefile for it:
PYTHON = /usr/include/python2.7
BOOST_INC = /usr/include
BOOST_LIB = /usr/lib
TARGET = arrayClasses
$(TARGET).so: $(TARGET).o
g++ -shared -Wl,--export-dynamic \
$(TARGET).o -L$(BOOST_LIB) -lboost_python \
-L/usr/lib/python2.7/config -lpython2.7 \
-o $(TARGET).so
$(TARGET).o: $(TARGET).cpp
g++ -I$(PYTHON) -I$(BOOST_INC) -c -fPIC $(TARGET).cpp
When I compile it I get:
g++ -shared -Wl,--export-dynamic \
arrayClasses.o -L/usr/lib -lboost_python \
-L/usr/lib/python2.7/config -lpython2.7 \
-o arrayClasses.so
/usr/bin/ld: arrayClasses.o: relocation R_X86_64_32 against `init_module_arrayClasses()' can not be used when making a shared object; recompile with -fPIC
arrayClasses.o: could not read symbols: Bad value
collect2: ld returned 1 exit status
What's wrong is there?

Answer 1

You have -fPIC for your .o target, but not
for the .so target. See if adding it helps.
Edit: Ignore that. This compiles for me on a 32-bit Ubuntu system using Python 2.6 and Boost 1.44. As Ignacio Vazquez-Abrams pointed out, you should probably check if your Python and Boost libraries were compiled for the same architecture.
