You either need to inline the ctor in the header or do an explicit
instantiation of _Variable somewhere

That doesn't work. When the compiler compiles varbls.cpp, it doesn't

Where is the definition of your _Variable template instances ? Your
newly compiled Python module can't find them. The likely cause is that
you forgot to link
Hi all,
right now I'm doing my first stepps in wrapping C++ code by ude of Boost.
So, there's a
template 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
#include
using namespace bo
