https://svn.boost.org/trac10/ticket/5283 <p> In the following code, extracted from libs/python/src/module.cpp, I think that "BOOST_PYTHON_DECL" has been omitted from the declaration of init_module(...). It was present in version 1.43 of Boost and without it I get unresolved symbol errors when linking against Boost::Python. </p> <p> In summary, I suspect that the third line in the fragment below should read: </p> <pre class="wiki">BOOST_PYTHON_DECL PyObject* init_module(PyModuleDef&amp; moduledef, void(*init_function)()) </pre><p> My apologies if this has, in fact, been removed deliberately. </p> <pre class="wiki">#if PY_VERSION_HEX &gt;= 0x03000000 PyObject* init_module(PyModuleDef&amp; moduledef, void(*init_function)()) { return init_module_in_scope( PyModule_Create(&amp;moduledef), init_function); } #else namespace { PyMethodDef initial_methods[] = { { 0, 0, 0, 0 } }; } BOOST_PYTHON_DECL PyObject* init_module(char const* name, void(*init_function)()) { return init_module_in_scope( Py_InitModule(const_cast&lt;char*&gt;(name), initial_methods), init_function); } </pre> en-us /htdocs/site/boost.png https://svn.boost.org/trac10/ticket/5283 Trac 1.4.3 Ralf W.
