When I try and "copy" a basic_ifstream<uint8_t> into a vector<uint8_t> I
recieve a bad cast exception. If the uint8_t is replaced with "unsigned char"
explicitly the problem persists, but if it is replaced with "char" the problem
goes away.
This has been confirmed not only on my system (GCC 4.1.1), but an Ubuntu system
running GCC 4.0.3 and another running GCC 4.1.2.
The code compiles and works fine under Microsoft Visual Studio .NET 2005. The
g++ problem has not been tested on a Windows system.
------
#include <vector>
#include <iterator>
#include <fstream>
#include <iostream>
#include <sstream>
#ifndef WIN32
#include "stdint.h"
#else
typedef unsigned char uint8_t;
#endif
using namespace std;
int main(int argc, char **argv)
{
if (argc != 2)
{
cout << "Usage: " << argv[0] << " <log filename>" << endl;
return 1;
}
// Open the input file
basic_ifstream<uint8_t> inputFile(argv[1], ios::binary);
if (inputFile.fail())
{
cout << "Failed to open the input file" << endl;
return 2;
}
// Read the file into a vector
vector<uint8_t> inputData;
istreambuf_iterator<uint8_t> inputDataStartIterator(inputFile),
inputDataEndIterator;
copy(inputDataStartIterator, inputDataEndIterator,
back_inserter(inputData));
}
