Re: [boost] Exporting C++ class with py_cpp problem

Adrien,

That's a compiler bug. There's not supposed to be a difference between the
signatures
    void set(const float f);
and
    void set(float f);

If you want to work around this bug and keep the parameter const within the
function body, separate the interface from the implementation:

    void set(float f); // declaration
    ...
    void set(const float f) { ; }

Regards,
Dave
