Hi all,
right now I'm doing my first stepps in wrapping C++ code by ude of Boost.
So, there's a
template<class TYPE> class _Variable
with ctor, dtor, an inspector
TYPE value() const
and a mutator
void value( const TYPE& value).
The boost wrapper looks like this:
#include <Python.h>
#include <boost/python.hpp>
using namespace boost::python;
#include "./src/varbls.h"
#include <string>
using namespace std;
typedef _Variable<double> VariableDouble;
BOOST_PYTHON_MODULE(_varbls)
{
class_<VariableDouble>("VariableDouble")
.def( init<>())
.def( init<const double&>())
;
}
Nothing special so far. However, what I get upon import is this:
ImportError:
/usr/lib/python2.7/site-packages/tau4.DDG/tau4/tau4misc/varbls/cpp/boost/_varbls.so:
undefined symbol: _ZN9_VariableIdEC1Ev
The ctor is decl'ed as
_Variable();
and ist's def'ed like so:
template <typename TYPE>
_Variable<TYPE>::_Variable()
: _value( 0)
{
//ctor
}
To me, everything looks good, but obiously there's something wrong. What
do I miss?
Paul
