[Swig-user] problems with static const data (redux)

[Mark T. <mt...@gm...>]

My apologies for the double send (stupid tab key)

so ... my class looks like:

namespace A
{
  namespace B
  {
    class C
    {
    public:

      static const unsigned int flag = 0x00000001;
    };
  }
}


There's obviously a bunch of other stuff though.  In the swig
interface file I have something like:

%module raytrace

%{
#include "c.h"
%}

%include "c.h"

When I build this for python and import it I get a linker error in the so as:

ImportError: _module.so: undefined symbol: _ZN3A8B3C10f_distanceE

Using c++filt I confirm that it's the flag that's missing.

My link line looks like:

g++ -Xlinker -export-dynamic -shared c.o <snip python crap> -o _c.so

I've tried RTFMing and googling, unfortunately despite the fact that
this must be a very common issue, I haven't stumbled on an answer.
I'm unsure if it's a result of the way I have written the swig
interface, or am linking all the objects.  Admittedly, I  don't
normally create .so's for general use, so it might be a fundamental
misunderstanding there.

Any help appreciated,

Mark.
