Hello,
I'm trying to use some C code I've written, using the ctypes module.
So, I've compile my C code into a shared object and written the
following code into the sage notebook :
from ctypes import *
myobj=CDLL("/home/mourad/Documents/PSTL/Simulator/simulator.so")
#I specify the return type of my functions
myobj.load_matrice_from_file.restype = c_void_p
myobj.load_card_from_file.restype = c_void_p
myobj.load_measure_device_from_file.restype = c_void_p
myobj.fuite_carte_to_gnuplot.argtypes = [c_char_p, c_void_p, c_void_p,
c_void_p]
#I run my functions
#on teste nos fonctions
mat = myobj.load_matrice_from_file("/home/mourad/Documents/PSTL/
fichier_tests/msg_test.msg")
card = myobj.load_card_from_file("/home/mourad/Documents/PSTL/
fichier_tests/msg_test.msg")
md = myobj.load_measure_device_from_file("/home/mourad/Documents/PSTL/
fichier_tests/msg_test.msg")
myobj.fuite_carte_to_gnuplot("/home/mourad/test.gnu", mat, card, md)
This code rise a segmentation fault.
I think the problem is that, even if I specified the return type of my
functions, they return a Python int.
I'm using Sage 3.4.2
Thank you.
