根据swig教程，很简单的例子程序 example.c（后面付有），就差最后一步，请指点：

方法一、MingW / DEV C++ 中的错误：
>swig -python example.i  (ok，得到example_wrap.c)
>gcc -c example.c example_wrap.c -I d:\python24\  (ok，得到两个.o文件）
>ld -shared example.o example_wrap.o -o _example.so (没通过，报错如下）：
......
example_wrap.o(.text+0x2b34):example_wrap.c: undefined reference to
`_imp__PyOS_snprintf'
example_wrap.o(.text+0x2bac):example_wrap.c: undefined reference to
`_imp__PyObject_Str'
example_wrap.o(.text+0x2bc2):example_wrap.c: undefined reference to
`_imp__PyString_AsString'
......

在DEV C++中加入了\python\libs, \python\include\, 编译错误通上：
......
  [Linker error] undefined reference to `_imp__PyExc_MemoryError'
  [Linker error] undefined reference to `_imp__PyExc_IOError'
......

python24为sf上下载的执行版，非本人编译，libs目录中不仅有python24.dll , 还有libpython24.a

方法二、Visual C++ 2005
python的include, libs都加入目录

编译错误：
Linking...
   Creating library d:\Ctest\t2\\test2.lib and object
d:\GF7\DigitalFilm\Ctest\t2\\test2.exp
example_wrap.obj : error LNK2001: unresolved external symbol "int
__cdecl fact(int)" (?fact@@YAHH在Z)

-----------------------------------------------

 /* File : example.c */

 #include 
 double My_variable = 3.0;

 int fact(int n) {
     if (n <= 1) return 1;
     else return n*fact(n-1);
 }

 int my_mod(int x, int y) {
     return (x%y);
 }

 char *get_time()
 {
     time_t ltime;
     time(<ime;);
     return ctime(<ime;);
 }

-------------------------------------

 /* example.i */
 %module example
 %{
 /* Put header files here or function declarations like below */
 extern double My_variable;
 extern int fact(int n);
 extern int my_mod(int x, int y);
 extern char *get_time();
 %}

 extern double My_variable;
 extern int fact(int n);
 extern int my_mod(int x, int y);
 extern char *get_time();
