Dear Numerical Python Users,

I have writen an extension using  GSL (Gnu Scientific Library) and
Numerical Python.
This extension work fine under Linux and I would to do the same under
Windows. For that I use Cygwin.
When I would create the module

$ gcc -shared Example.o -o Example.pyd

I receive this message :


Example.o<.text+0x58>:Example.c: undefined reference to
'PyArg_ParseTuple'
Example.o<.text+0x15e>:Example.c: undefined reference to 'Py_BuildValue'

Example.o<.text+0x1b1>:Example.c: undefined reference to
'Py_InitModule4'
Example.o<.text+0x1c1>:Example.c: undefined reference to
'PyImport_ImportModule'
Example.o<.text+0x1db>:Example.c: undefined reference to
'PyModule_GetDict'
Example.o<.text+0x1f4>:Example.c: undefined reference to
'PyDict_GetItemString'
Example.o<.text+0x206>:Example.c: undefined reference to
'PyCObject_Type'
Example.o<.text+0x214>:Example.c: undefined reference to
'PyCObject_AsVoidPtr'

Perhaps this command is wrong.

Perhaps, anyone could explain or show me a document which explain the
procedure clearly ?

Thanks in advance for your help

Omar
