Wrapping static member functions

[ptao]

I'm trying to use cython to wrap an existing c/c++ library. One
problem I'm having right now is with static member functions. For
example, the following:

namespace Test
{
class Test
{
public:
static int getInt();
};
}

If I try the following in my pyx:

cdef extern from "../c/test.h" namespace "Test":
cdef cppclass Test:
static int getInt()

def pgetInt():
print Test.getInt()

I get the following error:
test/cython/test.pyx:3:19: Syntax error in C variable declaration
building 'test' extension

If I leave off the static modifier in the pyx, it generates the wrong
c code.

What's the proper way to do this?

I think I would do some dirty hack to make cython believe getInt() is just a simple function in a namespace. I'm not sure if cython has a notion of "static" methods or not.

I can't test right now, but I would do something like this:

cdef extern from "../c/test.h" namespace "Test::Test":
    int getInt()

def pgetInt():
   print getInt()

I would be interested in a cleaner solution though :)

No, it doesn't have that notion, at least not for C++.

Yep. That's the only way to do it now.

Thanks guys, that solution is a bit hacky but it's working.
