Question

Hi Friends
I am new to openGLES, trying to work with HelloArrow program using shaders from a
Site

but when i compiled i got the following error,

Source code
Download HelloArrow.zip

ERROR: 0:1: '<' : syntax error syntax error
ERROR: Parser found no code to compile in source strings.

//  VERTEX SHADER


const char* SimpleVertexShader = STRINGIFY(
    attribute vec4 Position; 
    attribute vec4 SourceColor;
    varying vec4 DestinationColor; 
    uniform mat4 Projection; 
    uniform mat4 Modelview;

void main(void)
    {
        printf("fragment shader");
        DestinationColor = SourceColor; 
        gl_Position = Projection * Modelview * Position;
    }
);

//  FRAGMENT SHADER

const char* SimpleFragmentShader = STRINGIFY( 
    varying lowp vec4 DestinationColor;
    void main(void)
    {
    printf("fragment shader");
        gl_FragColor = DestinationColor;`
    } 
);

I don't have any idea.

Your suggestions are important to me so don't leave without a comment or answer

Answer 1

have a very close look at this line:

 gl_FragColor = DestinationColor;`

the character behind the ; should not be there
