link error - not accessible in profile

[skvinay]

Hello,

A very dummy program gives the following error:

Fragment info

(0) : error C5052: gl_Vertex is not accessable in this profile
(0) : error C5052: gl_Position is not accessable in this profile

What could i be doing wrong ?

Thanks

Can you say more things, like posting your dummy sources ?

Hi,

Here is my vertex program:

 
	"\
	void main()
\
	{
	\
	 	gl_Position = ftransform();
\
	}
\
	"

My fragment program:

  
	"\
	void main()
\
	{
\
		gl_FragColor = vec4(0.4,0.4,0.8,1.0);
\
	}
\
	"

My function call is:

glLinkProgram( m_Program );

where m_Program is the program id

On a NVidia GO 6800 card, I get the error:

Fragment info

(0) : error C5052: gl_Vertex is not accessable in this profile
(0) : error C5052: gl_Position is not accessable in this profile

On a fx 5900, I get a more verbose error:

Vertex info

I hope someone has some idea on whats wrong.

Thanks,

If you post a exe I’ll have a look.
I bet you are incorrectly supplying the strings to OpenGL…

[Relic]

Looks like the compiler generated empty programs.
If that is C you don’t need to put \ at the end of lines to concatenate strings, just put " " around each line.
You can use glGetShaderSource to see if source strings OpenGL has are what you think you sent.

[jide]

Just to ensure (sorry if it’s so easy, but we never know), did you well compiled the shaders first before linking them ?

(sorry again if that’s noway)

Hi folks,

I got past that So now I am storing programs as strings in classes.

I have to declare

 
     private:
		static const char* vertexShader;
		static const char* fragmentShader;
 

and fill it up in the cpp file. If I try to init in header, things mess up.

Thanks all.
