[C++-sig] Indexing suite v2 multiple module problem
Hi, I'm using a version of the indexing suite I believe I copied from Roman's codebase some time ago. I've recently refactored my project into multiple modules and now I'm have some runtime errors when iterating over sequences in python. At runtime I get the cryptic message: RuntimeError: get It is proving a little difficult to track down as it only happens on my server not on my development machine although it is reproducible every time. Not all std::vectors that are exposed trigger the error. If I change the order that my C++ modules are imported then the std::vector that triggers the error changes. I'm building a debug python on my server to try to investigate further but meanwhile I wonder if anyone had any suggestions or had seen this sort of thing before? Also where is the latest version of the indexing suite v2 code that I could use?

Do you use dlopen? import sys sys.setdlopenflags(RTLD_NOW | RTLD_GLOBAL) In multi-module environment you have to share boost python registry. I would start with this. You can google for "boost python dlopen" and find a lot of information about the subject. If I remember right, Py++ contains (generates) some code that queries the registry and registers the class conditionally.

(Sorry if this is a duplicate post, the last one seemed to disappear) Thanks, your advice fixed it: # # Need to set dlopen flags for multi-module boost.python environment # import sys, DLFCN sys.setdlopenflags(DLFCN.RTLD_NOW | DLFCN.RTLD_GLOBAL) ___ Cplusplus-sig mailing list Cplusplus-sig@python.org http://mail.python.org/mailman/listinfo/cplusplus-sig
