thanks for reply. i already tried bring a python31.dll with my application,but when i copy them to a computer without python installed,the initialization will fail,and i got a error message as: Fatal Python error: Py_Initialize: can't initialize sys standard streams ImportError: No module named encodings.utf_8 This application has requested the Runtime to terminate it in an unusual way. Please contact the application's support team for more information. i think maybe i have to take more than just a dll with my distribution... and this is not so comfortable for a application which just want some python scripting ability... 2009/9/13 <capi-sig-request(a)python.org> > Send capi-sig mailing list submissions to > capi-sig(a)python.org > > To subscribe or unsubscribe via the World Wide Web, visit > http://mail.python.org/mailman/listinfo/capi-sig > or, via email, send a message with subject or body 'help' to > capi-sig-request(a)python.org > > You can reach the person managing the list at > capi-sig-owner(a)python.org > > When replying, please edit your Subject line so it is more specific > than "Re: Contents of capi-sig digest..." > > > Today's Topics: > > 1.

how to distribute a application which with python scriptting ability?

by cloudage＠gmail.com

i use win32 and msvc9,i have installed the python3.1 on my computer,and i played with it for several days.i also played the Boost.Python that enable me easily export classes into python,but now when i want to distribute my application to another computer without python installed,i `m confused. so plz consider an application which: 1. Exported some packages from itself to python and have a UI like a script editor window that enable user type python script in and excute it. 2. Users can only use these packages supported by application it self to maintain the application,they are limited to use the dangerous default packages like io things provided by original python distribution. i thought there may be a python.dll that i just need take it with my application,but seems i`m wrong,there isn`t such a file looks like a python redistribute runtime.and about the question 2,the computer without python installed can not have a python path that i should copy my pyd into. so how should i do these?i totally have no idea. thanks for any help.

ANN: PyBindGen 0.12 released

by Gustavo Carneiro

PyBindGen is a Python module that is geared to generating C/C++ code that binds a C/C++ library for Python. It does so without extensive use of either C++ templates or C pre-processor macros. It has modular handling of C/C++ types, and can be easily extended with Python plugins. The generated code is almost as clean as what a human programmer would write. It can be downloaded from: http://code.google.com/p/pybindgen/ Bug reports should be filed here: https://bugs.launchpad.net/pybindgen === pybindgen 0.12 === - Now we can catch C++ exceptions and translate them into Python - New API to add container iteration powers to wrapped C++ classes - Unary minus operator support (J. Michael Owen) - CppMethod: is_pure_virtual=True should imply is_virtual=True - More polish for numeric operators with non-class right operand - Virtual methods regressions fixed - gccxmlparser: don't try to wrap private/protected operators - MSVC compilation fix - unsigned long type handlers (J. Michael Owen) - tp_len/__len__ works now with overloaded methods (J. Michael Owen) - Add foreign_cpp_namespace option to Function wrappers - Misc. cleanup and bug fixes -- Gustavo J. A. M.
