Linux/AM4379: OpenGL ES compilation errors

Part Number:AM4379

Tool/software: Linux

Hi forum,

I am using am437xgpevm and i am trying to render a simple rectangle using sitara sdk.

#include<GLES/gl.h>
#include <GLES/glplatform.h>

void colored_rect(GLfloat left, GLfloat bottom, GLfloat right, GLfloat top, GLfloat R, GLfloat G, GLfloat B)
{
    GLfloat rect[] = {
        left, bottom,
        right, bottom,
        right, top,
        left, top
    };
    glEnableClientState(GL_VERTEX_ARRAY);
    glColor3f(R,G,B);
    glVertexPointer(2, GL_FLOAT, 0, rect);
    glDrawArrays(GL_TRIANGLE_FAN, 0, 4);
}
void main(){
	colored_rect(0,50,150,0,255,0,0);
}

I can see that the libraries are in the header files specfied but when i compile i get the following errors.

10:22:39 **** Incremental Build of configuration Debug for project gles ****

Any help would be appreciated or am i missing something here ?
