Dev-C++/gcc compile question

[mikejfe]

Hi all. I've written a program that dynamically allocates memory for a 3dim array, reads a file into that array, does some stuff to the data in the array and then outputs the array to a file.

I can compile my program with Dev-C++ and run it all day long on my laptop (Windows XP). The problem with this is my laptop is slow. So, I tried to compile the code with gcc on my Linux box. gcc, however, doesn't seem to like my code.

The error I get says: "In function `__static_initi alization_and_d estruction_0(in t, int':." Then errors go on for another page or two. I've included the code that makes the array (if I need to include more code, I'll be more than happy).

I know about enough C++ to get done what I need, and am a new Linux user.

Thanks in advance for your help.

#include<fstream>
#include<iostream>
#include<math.h>
#include<string>

using namespace std;

// Voxel information array
float ***xyz = NULL;

int main()
{
// Ask user for input file
string filename;
cout << "File, array size (*.* DIM DIM DIM): ";
int numOfVoxelsX;
int numOfVoxelsY;
int numOfVoxelsZ;
cin >> filename >> numOfVoxelsX >> numOfVoxelsY >> numOfVoxelsZ;
string outputFileName;
cout << endl;
cout << "Output File Name (*.*): ";
cin >> outputFileName; 

cout << "Initializing" << endl;

xyz = new float**[numOfVoxelsX];
for (i = 0; i<numOfVoxelsX; i++)
  {
    xyz[i] = new float*[numOfVoxelsY];
    for (j = 0; j<numOfVoxelsY; j++)
      {
        xyz[i][j] = new float[numOfVoxelsZ];
      }
  }
cout << "Space allocated." << endl;

You didn't post this function: __static_initia lization_and_de struction_0.

And you didn't post the errors you are getting. Generally, only the first error is important. Fix it and the others may go away.

Honestly, I don't even know what function that is. I didn't knowingly call it. This program is so simplistic; there is no header file and everything I do is completely contained in int main().

The first few lines of the errors are:

/tmp/ccN8BUK4.o: In function `__static_initialization_and_destruction_(int, int)':
VoxelizedPhantomResizer.cpp:(.test+0x23): undefiend reference to 'std::ios_base:Init:Init()'

VoxelizedPhantomResizer.cpp:(.test+0x23): undefiend reference to 'std::ios_base:Init:~Init()'

The rest of my code follows (continuing from my first post):

int j = 0;
int k = 0;

      while(!fin.eof())
        {          
          ws(getline(fin,filevalue, ' '));
          filevalueConstChar = filevalue.c_str();
