I did come across IronPython, which is supposed to run off the .NET CLR. Rather surprisingly it seems more efficient than the Python VM (except for compilation/eval). Nick

Aggggggghhhhhhhh. And arrrghhhhgghhhh again. You need to put: #pragma unmanaged before the Boost headers and around any code that uses Boost. Jeez.

Embedding in .NET architecture
by Nick Trout June 4, 2004

June 4, 2004

Hello! I'm trying to embed Python into Windows Forms Application I'm working on. .NET is relatively new to me and having just got over the Managed objects vs unmanaged objects problems I'm now having trouble getting Boost working. My objective is to start up an application and then use Python scripts to customise the application and do various processing. I want to expose various features of the application to Python to enable this. Given what I am trying to do I think it's more appropriate to embed than to extend. I've been through the archives and looked at the embedding.cpp test example that is in the Boost source but I can't seem to find any information which fixes my problem. When I run the test suite the embedding.cpp example works when bjam compiles and runs it. However, when I copy the example into my code and run it throws and exception which crashes the application. I'm trying to get my application running using multithreaded DLL support. I've tried linking Boost against libboost statically linked libraries and against the boost_python dynamic libraries but I keep getting exceptions of various kinds (TEH, missing types etc). I know Boost works with MSVC 7.1 because other people seem to be using it and all the tests suite worked for me. What I haven't been able to do is get Boost.Python working in a MSVC app that uses managed objects. I'm therefore assuming that I don't have the correct settings, am missing some configuration #define or am just too much of a novice at the .NET framework to understand what the problem is. One thing I haven't tried, which is repeated on the mailing list is to build my application using bjam. I haven't tried this as I don't know how it would work with all the "assemblies" and stuff that goes into a WFA. I really don't want to have to do this if I can avoid it. Current problem I am having: When I run the embedded code in my app: if (python::handle_exception( test )) { if (PyErr_Occurred()) PyErr_Print(); return 1; } The exception handler fails because apparently test provides an invalid (NULL) pointer so f() has nothing to call in the try-catch handler. If I call test() directly in: <<<< // Register the module with the interpreter if (PyImport_AppendInittab("embedded_hello", initembedded_hello) == -1) throw std::runtime_error("Failed to add embedded_hello to the interpreter's " "builtin modules"); // Initialize the interpreter Py_Initialize(); // Retrieve the main module python::object main_module = python::extract<python::object>( PyImport_AddModule("__main__") )(); // Retrieve the main module's namespace python::object main_namespace(main_module.attr("__dict__")); >>>> Execution gets as far as "python::object main_module..." and I get the following error: <<<< An unhandled exception of type 'System.TypeLoadException' occurred in WorldEditor.exe Additional information: Could not load type boost.python.detail.new_non_null_reference_t from assembly WorldEditor, Version=1.0.1616.28683, Culture=neutral, PublicKeyToken=null. >>>> I've tried to set all of the correct project settings. I have asynchronous exeception handling turned on (/EHa) as opposed to the default (/EHsc) and RTTI is on. I hope you can help please. It may be obvious to a .NET expert. If not, I'll probably give this another day and move to PyCXX (and then Lua!) Nick

A problem here would be what to do in the differing cases of: - building a single pyste file into a module : in this case specifying exception handlers in the pyste file is sufficient - building many pyste files into a single module : in this case you probably want exception handlers to be specified in a module-level file, or perhaps you could put them in an arbitrary pyste file I think Pyste has some deficiencies in organising modules from multiple files. It is wonderful that this can be done, but I don't like that so much has to be specified on the command-line (and that the meaning of command-line options changes depending on --multiple or not). I think a better organisation would involve a module-level file, which could then contain such things as exception handlers. This would also make building modules out of several pyste files cleaner. (A disadvantage is that it expands the scope of the tool into something of a build tool). What do others think?

Linker errors with VC7.1 (.NET) and Python.Boost 1.31.0
by Igor Lapshin June 2, 2004

June 2, 2004

Hello all, I solved the problem: I added python_boost.lib library into the project. I am still wondering why this library was not put into Boost/lib directory and why my project worked on Linux without that library (I also used non-standard build mechanism and only a single boost_python-gcc-mt-d library) Regards, Igor

Linker errors with VC7.1 (.NET) and Python.Boost 1.31.0
by Igor Lapshin June 2, 2004

June 2, 2004

Hi, I'm trying to compile the following code within MS Visual Studio IDE .NET 2003. I compiled Boost 1.31.0 usign bjam, but I have the requirement that all exposed into Python classes must be compiled within IDE. "no_init" was specified because the original class has pure virtual functions, but I get the same errors even without them. The original class links and works fine on Linux/gcc, so I suppose I have problems specific to VC7.1 and Windows. class myclass { const char* name; public: myclass(); const char* getName(); }; myclass::myclass(): name("I'm a class") {} const char *myclass::getName() { return name; } using namespace boost::python; BOOST_PYTHON_MODULE(testme) { class_<myclass,boost::noncopyable>("myclass", no_init) .def("getName", &myclass::getName) ; } I specified libboost_python-vc71-mt-gd.lib as link library. test_boost.obj : error LNK2019: unresolved external symbol "__declspec(dllimport) void __cdecl boost::python::objects::register_dynamic_id_aux(struct boost::python::type_info,struct std::pair<void *,struct boost::python::type_info> (__cdecl*)(void *))" (__imp_?register_dynamic_id_aux@objects@python@boost@@YAXUtype_info@23@P 6A?AU?$pair@PAXUtype_info@python@boost@@@std@@PAX@Z@Z) referenced in function "void __cdecl boost::python::objects::register_dynamic_id<class myclass>(class myclass *)" (??$register_dynamic_id@Vmyclass@@@objects@python@boost@@YAXPAVmyclass@@ @Z) Am I missing something? Do I always need to write a wrapper class for "no_init"? Thanks, Igor

Pyste patch to generate default policy for virtual methods
by paul.bridger June 1, 2004

June 1, 2004

Nicodemus, For virtual methods, Pyste doesn't a) complain when they aren't given a policy, and b) give them the default return_value_policy(copy_const_reference) Here's a patch for that. I also made Pyste insert comments in generated code to show where various elements are exported. I have found this useful in editing my pyste files, but I don't care if you don't want that for mainstream Pyste.
