As Alex said, this seems to be a C++ issue. Hope you'll help me
nevertheless. There can't be that much that's missing.
How do I do that export?
This whole mess is caused by the use of a template class. You see, there's a
class VariableFloat. It is not a template class and is not derived from a
template class. And it works, I can use it from w/i my Python modules. Well,
it's deactivated for now to prevent "side effects".
Yes, I have to provide a TYPE to the tempate to enable the compiler to
generate code. Isn't
typedef _Variable<double> VariableDouble;
BOOST_PYTHON_MODULE(_varbls)
{
class_<VariableDouble>("VariableDouble")
.def( init<>())
.def( init<const double&>())
;
}
doing that?
