[C++-sig] boost::python on Linux

[Jim Treadway]

I'm having trouble getting a simple boost::python sample program to
work properly on Linux.  It compiles and seems to link properly, but the Python
interpreter is unable to call my C++ function.  On Mac OS X the
program works as expected.

Any help would be appreciated, hopefully I'm missing something obvious.

The program output is:

-- BEGIN --
Traceback (most recent call last):
 File "<string>", line 1, in <module>
Boost.Python.ArgumentError: Python argument types in
   Test.test(int)
did not match C++ signature:
   test(int)
-- END --

Here is the code.  It's compiled and linked using "g++
-I/usr/include/python2.5 -lpython2.5 -lboost_python -Wall -o test
test.cpp".  On the Linux box I'm using boost-1.37.0 and python-2.5.2.

-- BEGIN --
#include <stdlib.h>
#include <string>
#include <boost/python.hpp>

using namespace boost::python;

/* g++ -I/usr/include/python2.5 -lpython2.5 -lboost_python -Wall -o
test test.cpp */

int test(int i)
{
       fprintf(stderr, "%s:\n", __FUNCTION__);
       return i * 5;
}

BOOST_PYTHON_MODULE(Test)
{
       using namespace boost::python;
       def("test", test);
}

int main(int argc, char *argv[])
{
       Py_Initialize();

       try {
               initTest();

               PyRun_SimpleString("import Test");
               PyRun_SimpleString("print 'calling test function'");
               PyRun_SimpleString("print Test.test(5)");
       } catch (boost::python::error_already_set) {
               PyErr_Print();
       }

       Py_Finalize();
       return 0;
}
-- END --
