I am calling a small C++ executable taking some commad line arguments in the Python. In C++ code i am tring to open a file it works fine if i execute the code form the shell but if i call it through python code the file cannot be opened.
Python Code
*********************************************
#! /usr/bin/env python
import os
import sys
test = ['qtl']
f = open('settings.ini','r')
for line in f.readlines():
print line
test.append(line)
f.close()
print test[0]
print test[1]
print test[2]
os.execv("qtl",test)
********************************************
should i use anyother command to rum this "qtl"
C code (qtl.cpp)
********************************************
#include <iostream.h>
#include <stdlib.h>
#include <fstream.h>
int main(int argc, char *argv[])
{
char buffer[256];
char* name;
int number;
//cout << "argc = " <<argc <<endl;
if(argc < 2)
{
cout << "Enter 2 arguments ...."<<endl;
return 0;
}
cout<<"argv[0] "<<argv[0]<<endl;
cout<<"argv[1] "<<argv[1]<<endl;
cout<<"argv[2] "<<argv[2]<<endl;
name = argv[2];
number = atoi(argv[1]);
cout <<"file name = "<<name<<endl;
ifstream examplefile(name);
cout <<"number is >> "<< number<<endl;
if(!examplefile.is_open())
{
cout <<"problem in openning of file";
return 0;
}
while (examplefile.getline(buffer,256))
cout <<buffer<<endl;
examplefile.close();
return 0;
}
********************************************
Result if i run python code ./run.py
********************************************
-bash-3.00$ ./run.py
12
abc.txt
qtl
12
abc.txt
argv[0] qtl
argv[1] 12
argv[2] abc.txt
file name = abc.txt
number is >> 12
problem in openning of file
********************************************
Thanks in advance
