Not sure what you mean:
The ctor is decl'ed in varbls.h as
_Variable();
and it's def'ed in varbls.cpp like so:
template <typename TYPE>
_Variable<TYPE>::_Variable()
: _value( 0)
{
//ctor
}
I did a typedef in the wrapper and wrote
BOOST_PYTHON_MODULE(_varbls)
{
class_<VariableDouble>("VariableDouble")
.def( init<>())
.def( init<const double&>())
;
}
in the wrapper.
Any instance of VariableDouble should then be def'ed in the importing Python
module.
Everything works fine if I do not use templates but plain C++ classes
instead.
