I’m trying to load an openGL texture for a game. The texture is an image that has been exported as a .C source file from GIMP. When I #include this file in my project (using Visual C++ 2010 Ultimate), I get a compiler error saying fatal error C1091: compiler limit: string exceeds 65535 bytes in length

Is there any workaround ?

The reason I wanted to export the image as a C header file was so that the program compiles with the image, and I dont have to provide raw image files along with the executable.

Code:

#include <iostream>
#include <Windows.h>
#include <glfw.h>
#include "X.c"

#define X 1
#define O 2

#pragma comment(lib, "glfw.lib")
#pragma comment(lib, "opengl32.lib")
#pragma comment(lib, "gdi32.lib")

using namespace std;

float render();
void stepGame(float);
void keyboard(int, int);

int main(int argv, int *argc[])
{
    glfwInit();
    glfwOpenWindow(480, 480, 16, 16, 16, 16, 16, 16, GLFW_WINDOW);
    glfwSetKeyCallback(keyboard);
    glfwSetWindowTitle("Tic Tac Toe!");
    glClearColor(1.0, 1.0, 1.0, 1.0);
    float dT;

    while(glfwGetWindowParam(GLFW_OPENED) > 0)
    {
        glfwPollEvents();
        dT = render();
        stepGame(dT);
    }
    return 0;
}

Image file:
X.c

    Here is an alternative solution. Export the image as a raw data file, then use bin2hex to convert it to a C/C++ array. This will work fine because instead of a huge string this script generates a char array. Here is an example:

    $ bin2hex.pl
bin2hex.pl by Chami.com

usage:
  perl bin2hex.pl <binary file> <language id>

  <binary file> : path to the binary file
  <language id> : 0 = Perl, 1 = C/C++/Java, 2 = Pascal/Delphi

$ bin2hex.pl x.bin 1

/* begin binary data: */
char bin_data[] = /* 112 */
{0x23,0x69,0x6E,0x63,0x6C,0x75,0x64,0x65,0x20,0x3C,0x73,0x74,0x64,0x69,0x6F
