Ah, I lied. The def's were happening in a different module. Would that be the cause? -----Original Message----- From: boost-users-bounces@lists.boost.org on behalf of Sohail Somani Sent: Wed 5/23/2007 7:30 AM To: boost-users@lists.boost.org Subject: [Boost-users] [Python] Exposing foo(std::vector<double>) Hi, Given: foo(const std::vector<double> &) Is there anything special I need to do to expose foo above? I have: ..MODULE(test) { def("foo",foo); } I've also tried: ...MODULE(test) { class_("vector_d") .def(vector_indexing_suite<...>) ; def("foo",foo); } In both cases, I get Boost.Python throwing an error saying that the signature doesn't match when being called from Python. If there is some documentation I have overlooked, I would appreciate a pointer. Sohail
