(python study) C Module for using in python using distutils (and Unable to find vcvarsall.bat problem)
The method to make C module for using in python using Visual Studio IDE is introduced on the http://feelmare.blogspot.kr/2014/02/python-study-c-module-for-using-in.html
In this page, I will introduce to make c module using distutils.
The method to use distutils is more simple than VS version.
Firstly, we have to make setup.py file like this.
...
type "python setup.py install" on the command line.
Note, python.exe, setup.py, spammodule.c is placed in same folder.
In this page, I will introduce to make c module using distutils.
The method to use distutils is more simple than VS version.
Firstly, we have to make setup.py file like this.
...
# -*- coding: cp949 -*- # python # install method : setup.py install # setup.py -help #from distutils.core import setup, Extension from distutils.core import setup, Extension spam_mod = Extension('spam', sources = ['spammodule.c']) setup (name = "spam", version = "1.0", description = "A sample extension module", ext_modules = [spam_mod], )---
type "python setup.py install" on the command line.
Note, python.exe, setup.py, spammodule.c is placed in same folder.
After running, Our .pyd (lib) is made in the python\Lib\site-packages
Now, we can import spam
!!!
If you meet "unable to find vcvarsall.bat" error, dont be worry, 't is not serious error.
I also meet this error and solve.
The problem is occurred python find vs 9.0 version even though my computer installed vs 11.
so correct this miss-match.
firstly, try this method
if you cannot solve error
try this method
open python/Lib/distutils/msvc9compiler.py
and modify code like figure.
I solved this error by second method.
good luck~!!
(python study) C Module for using in python , in Visual Studio
Firstly, I describe to make C module in Visual Studio.
...
rename ~.dll to spam.pyd
If module name is not matched, cannot use module, error occurred when run in python.
copy spam.pyd into python\LIB folder
In the python, programing following source and run~!
...
And introduce using distutils -> http://feelmare.blogspot.kr/2014/02/python-study-c-module-for-using-in_11.html
open visual studio
make project -> win32 console application
check DLL, Empty project on setting page
make new .c file and set property
select Include directories and Library directories on the VC++ Directories page.
In my case, My installed python is located
Include -> C:\Python33_32\include
Library -> C:\Python33_32\libs (Caution, not LIB folder)
Notice, my compile option is release, because I have only release version lib(python32.lib),
Python32_d.lib file is not support default.
If you compile by debug version, you rebuild python source code to debug version by CMake.
programing this source code and compile~!
#include "Python.h" #pragma comment(lib, "python33.lib") static PyObject * spam_strlen(PyObject *self, PyObject *args) { const char * str = NULL; int len = 0; if(!PyArg_ParseTuple(args, "s", &str)) return NULL; //main source code len = strlen(str); return Py_BuildValue("i", len); } static PyMethodDef SpamMethods[] = { {"strlen", spam_strlen, METH_VARARGS, "count a string length."}, {NULL, NULL, 0, NULL} //represent end of array }; static struct PyModuleDef spammodule = { PyModuleDef_HEAD_INIT, "spam", //name of module "It is test module.", //description -1, SpamMethods }; PyMODINIT_FUNC PyInit_spam(void) { return PyModule_Create( &spammodule); }---
rename ~.dll to spam.pyd
If module name is not matched, cannot use module, error occurred when run in python.
copy spam.pyd into python\LIB folder
In the python, programing following source and run~!

Concise code

fast execution of a function
The module in python is similar with #include in C
To make module, make .py file.

(Window 2008) disable port 80 on the window 2008 os
I have to close the programs using port 80 to setup APM(Apache, PHP, Mysql)
But I cannot find which program use port 80 on the window 2008 environment.
After a long time later, I figured out the solution.
The method is like that
Control Panel> Administrative Tools> Services to find information about the following 'stop'
Properties in 'Manual' to change.
World Wide Web Publishing Service
SQL Server Integration Services 10.0
SQL Server Reporting Services (MSSQL SERVER)
If not this should not conflict with port 80, the user of MS SQL
1. Start> Programs> Microsoft SQL Server 2008> Configuration Tools> Reporting Services Configuration Manager, run
2. Server Connection
3. In the left menu 'Web service URL', the right to use port 80. -> Change to a different port
good luck~!!
