Importing modules in embedded Python
|
|
Hello everyone,
I can embed Python interpreter in C code now, but now there's another
problem, importing modules in Python code doesn't work:
Exception exceptions.ImportError:
'/usr/lib/python2.4/lib-dynload/timemodule.so: undefined symbol:
PyModule_AddObject' in 'garbage collection' ignored
Fatal Python error: unexpected exception during garbage collection
Aborted
The (autogenerated) C code:
---cut---
#include <Python.h>
#include <stdio.h>
#include <stdlib.h>
#include <syslog.h>
#include <unistd.h>
#include <signal.h>
void userbreak(int sig)
{
Py_Finalize();
printf("Interrupted..\n");
exit(sig);
}
void terminaterun(int sig)
{
Py_Finalize();
printf("Received SIGTERM. Terminating.\n");
exit(sig);
}
int main(int argc, char **argv)
{
Py_Initialize();
PyObject *pyCode, *mainmodule, *maindict;
mainmodule = PyImport_AddModule("__main__");
maindict = PyModule_GetDict(mainmodule);
unsigned int size = 272;
unsigned char python_code[] = { 0x63,0x00,0x00,

pyCode = PyMarshal_ReadObjectFromString((PyObject *)
python_code, size);
(void) signal(SIGINT, userbreak);
(void) signal(SIGTERM, terminaterun);
PyEval_EvalCode(pyCode, maindict, maindict);
Py_Finalize();
}
---cut---
The Python code:
import time
def test():
time.sleep(1)
print "success"
time.sleep(90)
How do I manage to get modules imported? Anybody?
