python-embedding

I am trying to embed a python program inside a C program. My OS is Ubuntu 14.04 I try to embed python 2.7 and python 3.4 interpreter in the same C code base (as separate applications). The compilation and linking works when embedding python 2.7 but not for the python 3.4. It fails during the linker stage. Here is my C code (just an example not real code) simple.c #include <stdio.h> #include <Python.h> int main(int argc, char *argv[]) { PyObject *pName, *pModule, *pFunc, *pValue; char module[] = "get_version"; char func[] = "get_version"; char module_path[] = "."; Py_Initialize(); PyObject *sys

I would like to embed Python interpreter in to a Qt 5 application. I have a working application in Qt 5 but when I put #include <Python.h> at the top (below Qt headers) the compilation breaks with ../sample/python3.3m/object.h:432:23: error: expected member name or ';' after declaration specifiers PyType_Slot *slots; /* terminated by slot==0. */ ~~~~~~~~~~~ ^ When I put Python header above the Qt headers it breaks with In file included from ../Qt5.0.1/5.0.1/clang_64/include/QtGui/QtGui:59: ../Qt5.0.1/5.0.1/clang_64/include/QtGui/qpagedpaintdevice.h:63:57: error: expected '}' A0, A1, A2, A3, A5

When messing around with Python.h I got this error: AttributeError: 'module' object has no attribute 'argv' C++ code: #include "stdafx.h" #include "C:/Python27/include/Python.h" #include <iostream> using namespace std; int main() { Py_Initialize(); PyRun_SimpleString("import sys\nprint sys.argv[0]"); } Which in Python is: import sys print sys.argv[0] What am I missing? Conceptually, sys.argv should contain the arguments that Python was called with (and what it was called under). What should it have if it were called like this, though? You can load the calling program's argv into sys , if you

If I embed the Python interpreter in a C or C++ program, as in this example , is there any way to limit how long the interpreter runs for? Is there anything to stop the Python code from entering an infinite loop and thus preventing PyObject_CallObject (or equivalent) from ever returning? Similarly, if the Python code creates a new thread, is there anything to stop this thread from entering an infinite loop and running forever? Peter Brittain As you can see in the docs , PyObject_CallObject has no mechanism for limiting how long the function runs. There is also no Python C API function that I

what are your advices on building a very minimalistic version of Python(2.x) for my application's scripting needs. My main motive here is to keep the foot print (both memory and disk wise) as low as possible so that my native application won't suffer from any major performance hit. Even the Python DLL size is in consideration because of the possibility of increasing boot up time of my application. Can we go as low as Lua or other lightweight solutions? Have you tried Tiny Python ? You can use only the dll 来源： https://stackoverflow.com/questions/356452/minimal-python-build-for-my-applications
