構建Python的擴展（3.2），但得到錯誤「找不到-lmsvcr90」

Question

我想在Windows上使用distutils構建Python的Python 3.2擴展（3.2）。下面 是代碼：（從在Python（3.1.3）源分佈演示/嵌入/ demo.c）

/* Example of embedding Python in another program */ 

#include "Python.h" 

PyObject* PyInit_xyzzy(void); /* Forward */ 

main(int argc, char **argv) 
{ 
    /* Ignore passed-in argc/argv. If desired, conversion 
     should use mbstowcs to convert them. */ 
    wchar_t *args[] = {L"embed", L"hello", 0}; 

    /* Pass argv[0] to the Python interpreter */ 
    Py_SetProgramName(args[0]); 

    /* Add a static module */ 
    PyImport_AppendInittab("xyzzy", PyInit_xyzzy); 

    /* Initialize the Python interpreter. Required. */ 
    Py_Initialize(); 

    /* Define sys.argv. It is up to the application if you 
     want this; you can also let it undefined (since the Python 
     code is generally not a main program it has no business 
     touching sys.argv...) 

     If the third argument is true, sys.path is modified to include 
     either the directory containing the script named by argv[0], or 
     the current working directory. This can be risky; if you run 
     an application embedding Python in a directory controlled by 
     someone else, attackers could put a Trojan-horse module in the 
     directory (say, a file named os.py) that your application would 
     then import and run. 
    */ 
    PySys_SetArgvEx(2, args, 0); 

    /* Do some application specific code */ 
    printf("Hello, brave new world\n\n"); 

    /* Execute some Python statements (in module __main__) */ 
    PyRun_SimpleString("import sys\n"); 
    PyRun_SimpleString("print(sys.builtin_module_names)\n"); 
    PyRun_SimpleString("print(sys.modules.keys())\n"); 
    PyRun_SimpleString("print(sys.executable)\n"); 
    PyRun_SimpleString("print(sys.argv)\n"); 

    /* Note that you can call any public function of the Python 
     interpreter here, e.g. call_object(). */ 

    /* Some more application specific code */ 
    printf("\nGoodbye, cruel world\n"); 

    /* Exit, cleaning up the interpreter */ 
    Py_Exit(0); 
    /*NOTREACHED*/ 
} 

/* A static module */ 

/* 'self' is not used */ 
static PyObject * 
xyzzy_foo(PyObject *self, PyObject* args) 
{ 
    return PyLong_FromLong(42L); 
} 

static PyMethodDef xyzzy_methods[] = { 
    {"foo",    xyzzy_foo,  METH_NOARGS, 
    "Return the meaning of everything."}, 
    {NULL,    NULL}   /* sentinel */ 
}; 

static struct PyModuleDef xyzzymodule = { 
    {}, /* m_base */ 
    "xyzzy", /* m_name */ 
    0, /* m_doc */ 
    0, /* m_size */ 
    xyzzy_methods, /* m_methods */ 
    0, /* m_reload */ 
    0, /* m_traverse */ 
    0, /* m_clear */ 
    0, /* m_free */ 
}; 

PyObject* 
PyInit_xyzzy(void) 
{ 
    return PyModule_Create(&xyzzymodule); 
} 

我建立 「setup.py」 文件是這樣的：

from distutils.core import setup, Extension 

module1 = Extension('xyzzy', 
        sources = ['demo.c']) 

setup (name = 'xyzzy', 
     version = '1.0', 
     description = 'This is a demo package', 
     ext_modules = [module1]) 

和他們，我運行 「的setup.bat」：

python.exe setup.py build -c mingw32 
pause 

，我得到了以下錯誤消息：

請按任意鍵繼續. . . 

我不明白「找不到-lmsvcr90」是什麼意思？順便說一下，我使用DEV C++的編譯器（是否有問題？）

有人可以幫助我，謝謝。

msvcr90是Microsoft Visual C運行時。 instructions for building on Windows僅描述使用Visual Studio;我不知道它是否可以與dev C++一起使用。您可以免費下載「Visual Studio Express」here。
