hi .. I was reading the tutorial "Extending and Embedding the python interpreter" available with python ..
http://www.python.org/doc/2.2.3/ext/ext.html As per given in the tutorial i created an interface to the system() system call. this is the code of my module Code: #include<Python.h> static PyObject * spam_system(self,args) { PyObject * self; PyObject * args; char * command; int sts; if ( !PyArg_ParseTuple(args, "s" , &command)) return NULL; sts = system(command); return Py_BuildValue("i",sts); } static PyMethodDef SpamMethods[] = { { "system", spam_system , METH_VARARGS,"Execute a shell command"}, {NULL,NULL,0,NULL} }; void initspam(void){ (void) Py_InitModule("spam", SpamMethods); } int main(int argc,char **argv) { // Py_SetProgName(argv[0]); /* I COMMENTED THE ABOVE CALL AS IT GAVE ME SOME WIERD ERROR */ Py_Initialize(); initspam(); } i was able to compile the above code using disutils package available with python . http://www.python.org/doc/2.2.3/ext/building.html I was even able to import the module into the python interpreter but caling the function gave me the following error Code: >>>import spam >>>spam.system("ls -l") python: Python/getargs.c:90: vgetargs1: Assertion `compat || (args != (PyObject*)((void *)0))' failed.
