Re: Embedding/Extending Python in/with C++: non-static members?

(I thought I'd follow up on this post so as not to send unsuspecting readers down a hopeless path) duh! I've obviously spent too much time with dynamic languages. The problem with what I'm trying to do is obvious: In C++ you simply can't pass pointers to call a particular instance of a C++ class

Embedding/Extending Python in/with C++: non-static members?

Hi Folks: I have a question about the use of static members in Python/C extensions. Take the simple example from the "Extending and Embedding the Python Interpreter" docs: A simple module method: static PyObject * spam_system(PyObject *self, PyObject *args) { ... } listed in a method table: s

Re: Embedded and extending python 2.5: trouble with __main__ in PyRun_SimpleFileExFlags?

I am going to answer this question myself, but perhaps this will be useful for someone else. My original C++ code was fine, the PyRun_SimpleFile was failing due to errors in my python code. To get a console and display the python interpreter errors I allocated a console, and redirected stdout and

Embedded and extending python 2.5: trouble with __main__ in PyRun_SimpleFileExFlags?

Hi Python fans, I am developing a DLL that is loaded by a host application on windows. I'm using python 2.5. My DLL uses an embedded python interpreter which can access the host application through an API which I have exposed using SWIG 1.3.31. Therefore I have both extended and embedded Python

return tuple from C to python (extending python)

Hi all, I want to make python call some C functions, process them and return them. Ok, I got all the wrapper functions and everything setup right. Here is my problem. What I need to do is to return a tuple from C to python. To go about doing this, I first create a tuple object in C doing the fo

Re: beginner questions on embedding/extending python with C++

Hi All, I am in the process also of trying to call Python script from a C++ windows app. I have looked at the Boost site and am currently reading over the Embedding portion of the tutorial. A question I have is that there appear to be about 4 or 5 Boost items avaiable for download. Which one should

Thanks for all the good pointers! I am still reading throught them, but Boost seems to be the way to go! Roman Yakovenko wrote: > On 8 Aug 2006 02:28:31 -0700, Qun Cao <[EMAIL PROTECTED]> wrote: > > Hi Everyone, > > > > I am a beginner on cross language development. My problem at hand is to > > bu

Re: beginner questions on embedding/extending python with C++

Thanks Diez, It is a good relief that I only need to wrap the classes I need. I decide to try Boost first because it seems to have a wider audience than SIP, but I would definately look into SIP if I want to do Qt development in the future. Diez B. Roggisch wrote: > > Since the main program is s
