I have installed devil. But when I run my program, I am not able to see the texture mapped, it shows plane surface. And the following error:

 

/********************************************/

1291:invalid extension/n1290: could not open file /n

/*********************************************************/

 

Please provide me suggestion to fix the error.

Need more info... post some code...

 

How are you opening the file?

Here is my code detail. I can compile and run, but can't see the texture. I have attached the texture file.

Hmm, looks alright to me... there is a textures folder beneath the exe location, and you're not changing the working directory are you?

 

What happens if you use the fully qualified path instead (e.g. "c:\\myapps\\textures\\1.bmp" or whatever)?

 

And you want to be using \n not /n in your printf, \n is a newline.

If I use absolute path as you have said, I find the same error. If I run the object file with the texture in same directory, similar error is shown.

 

 I have fixed '/n' to '\n'.

 

I am not sure what the rpoblem is. Please help me identify my problem.

First of all don't use glut, use freeGLUT or glfw.

 

GLUT is decades old and not supported any more, and it's not open source.

 

Second, it maybe because you didn't use code tags and this is a forum but your spacing and tabs is horrible.

 

Third, you may want to use freeImage instead of devIL because it's been updated more and makes it even easier to load pretty much any common format.

If you built the devIL code yourself (and added it to the solution as a project, assuming Visual Studio) you should be able to step into the ilutGLLoadImage function and see why it is failing. That's all I can think of right now...
