OpenGL texture loading with soil help need - c++

Question

Here is the code. Please help guys
#include <GL/glut.h>
#include <iostream>
#include <math.h>
#include "SOIL.h"
using namespace std;
GLuint texture[1];
int LoadGLTextures()
{
texture[0] = SOIL_load_OGL_texture
(
"NeHe.bmp",
SOIL_LOAD_AUTO,
SOIL_CREATE_NEW_ID,
SOIL_FLAG_INVERT_Y
);
if(texture[0] == 0)
return false;
glBindTexture(GL_TEXTURE_2D, texture[0]);
glTexParameteri(GL_TEXTURE_2D,GL_TEXTURE_MIN_FILTER,GL_LINEAR);
glTexParameteri(GL_TEXTURE_2D,GL_TEXTURE_MAG_FILTER,GL_LINEAR);
return true;
}
void ChangeSize(int w, int h)
{
if(h == 0)
{
h = 1;
}
float ratio = 1.0f * w/h;
glMatrixMode(GL_PROJECTION);
glLoadIdentity();
glViewport(0,0,w,h);
gluPerspective(45,ratio,1,1000);
glMatrixMode(GL_MODELVIEW);
glLoadIdentity();
gluLookAt(0.0,0.0,6.0,
0.0,0.0,0.0,
0.0f,1.0f,0.0f);
}
void display(void)
{
glClear(GL_COLOR_BUFFER_BIT | GL_DEPTH_BUFFER_BIT);
glEnable(GL_TEXTURE_2D);
glBindTexture(GL_TEXTURE_2D, texture[0]);
glBegin(GL_QUADS);
glTexCoord2f(0.0f, 0.0f); glVertex3f(-1.0f, -1.0f, 1.0f);
glTexCoord2f(1.0f, 0.0f); glVertex3f( 1.0f, -1.0f, 1.0f);
glTexCoord2f(1.0f, 1.0f); glVertex3f( 1.0f, 1.0f, 1.0f);
glTexCoord2f(0.0f, 1.0f); glVertex3f(-1.0f, 1.0f, 1.0f);
glEnd();
glFlush();
}
void idle(void)
{
glutPostRedisplay();
}
int main(int argc, char *argv[])
{
glutInit(&argc, argv);
glutInitWindowSize(640,480);
glutInitWindowPosition(10,10);
glutInitDisplayMode(GLUT_RGB | GLUT_SINGLE | GLUT_DEPTH);
glutCreateWindow("ZC");
glutReshapeFunc(ChangeSize);
glutDisplayFunc(display);
glutIdleFunc(idle);
glEnable(GL_DEPTH_TEST);
glutMainLoop();
}
I dont get errors, but not loading the texture.

You forgot to call LoadGLTextures in your main program. I ran your program with this change:
glEnable(GL_DEPTH_TEST);
LoadGLTextures(); //<-- added this
glutMainLoop();
}
and things worked fine.
I provided my own NeHe.bmp file, since you didn't link to one. It could also fail if your .bmp file is bad in some way.
