Getting a LINK Error:1104 can''t open file. When recompiling my App. It seems the process is not getting killed when the program recieves the WM_CLOSE message. The process still runs in the background and I can''t re-compile till I re-start my computer. This is getting frustrating to say the least! The app runs fine the first time then if I make changes to the code and recompile I get this error. Any suggestions? My code is based on HeHe''s Tutorials #10...and...#32. It loads a Milkshape model and Several Quadratics that have their own image maps. Not sure where to start looking or I would post my code here. I assume it''s somewhere in KillGLWindow() or WinMain()? Sparky Robert Snyder

You''ll want to be careful how closely you are copying code between the two. For #32 I basically ripped out bits of tut #6 to use and adapted them so they have the NeHe tutorial style.

To kill the process, use CTRL-ALT-DEL. But you shouldn''t have to. How are you closing the app.?

There might be a bit too much code to post, but if you can narrow it down and post that information it would make it easier to figure out what is wrong.

Thanks for the reply Brett. I made no changes to the code that origianly closed the tutorials. And the process isn''t visible with Ctrl+Alt+Del. It seems to be leaving something behind. Could I have a memory leak somwhere? Some memory space not getting deallocated? Still learning about dynamic allocation.

One thing that might be a problem is that I am using your Texture Loading code from Lesson 32 and the Texture loading code from Lesson 10 combined in one call to LoadGLTexture(). I have to think there is a better way to do this!

GLuint LoadGLTexture( const char *filename )
{
AUX_RGBImageRec *TextureImage[5];
memset(TextureImage,0,sizeof(void *)*5);
if ((TextureImage[0]=LoadBMP("Data/earth2.bmp")) &&
(TextureImage[1]=LoadBMP("Data/moon2.bmp")) &&
(TextureImage[2]=LoadBMP("Data/mars.bmp")) &&
(TextureImage[3]=LoadBMP("Data/venus.bmp")) &&
(TextureImage[4]=LoadBMP("Data/jupiter.bmp"))

{
glGenTextures(5, &texture[0]);

for (int loop1=0; loop1<5; loop1++)
{
glBindTexture(GL_TEXTURE_2D,texture[loop1]);
glTexParameteri(GL_TEXTURE_2D,
GL_TEXTURE_MAG_FILTER,GL_LINEAR);
glTexParameteri(GL_TEXTURE_2D,
GL_TEXTURE_MIN_FILTER,
GL_LINEAR_MIPMAP_NEAREST);
gluBuild2DMipmaps(GL_TEXTURE_2D, 3, TextureImage[loop1]->sizeX,
TextureImage[loop1]->sizeY,
GL_RGB, GL_UNSIGNED_BYTE,
TextureImage[loop1]->data);
}

for (loop1=0; loop1<5; loop1++)
{
if (TextureImage[loop1])
{
if (TextureImage[loop1]->data)
{
free(TextureImage[loop1]->data);
}

free(TextureImage[loop1]);
}
}
}



AUX_RGBImageRec *pImage;
GLuint texture = 0;

pImage = LoadBMP( filename );
if ( pImage != NULL && pImage->data != NULL )
{
glGenTextures(1, &texture);
glBindTexture(GL_TEXTURE_2D, texture);
gluBuild2DMipmaps(GL_TEXTURE_2D, 3, pImage->sizeX, pImage->sizeY, GL_RGB,
GL_UNSIGNED_BYTE, pImage->data);
glTexParameteri(GL_TEXTURE_2D,
GL_TEXTURE_MIN_FILTER,
GL_LINEAR_MIPMAP_NEAREST);
glTexParameteri(GL_TEXTURE_2D,
GL_TEXTURE_MAG_FILTER,GL_LINEAR);

free(pImage->data);
free(pImage);
}

return texture;
}

By the way, I downloaded your PortaLib3D and when compiling, it tells me I''m missing "png.h".
