[C++-sig] static/dynamic boost::python conflicts?

[Koichi Tamura]

Hello,
I'm using boost::python and I've got a problem now.

 I'm writing a shared library(bundle, I'm using MacOSX10.5, and it's a
plug-in for some
application) where I have a code like this.

    //....on init....
    if ( ! Py_IsInitialized())
    {
        int a = PyImport_AppendInittab("MyModule", &initMyModule);
        Py_Initialize();
        PyEval_InitThreads();
        PyEval_ReleaseLock();
    }

    //....somewhere else...
    PyGILState_STATE state = PyGILState_Ensure();
    module = object(handle<>(PyModule_New(moduleName)));
    myMod = object(handle<>(PyImport_ImportModule("MyModule")));
    module.attr("mymod") = myMod;
    PyGILState_Release(state);

I statically linked boost::python, and it works fine. When imported,
MyModule is
filled with classes that boost::python has wrapped.

But when I use another shared library(#) which dynamically links
boost::python
together with mine, PyImport_ImportModule("MyModule") returns a module which
dict
is empty but __doc__ and __name__.

Instead of (#) I made a test shared library that does nothing but linking
boost::python dynamically, and it still fails.

Why does all statically linked boost::python and extension is affected by a
dynamically
linked boost::python? I'm really puzzled.


I would really appreciate if anybody could help.
