This is my code and I am working on Macbook with OpenGL with
- freeglut 3.0.0
- glew 2.1.0
- glfw 3.3
- gsl 2.6
but still I am getting the error as posted in the error image. The code is about displaying a triangle using c++ and OpenGL library if someone can
So here is the code If someone can help please
#include <GL/glew.h>
#include <GL/freeglut.h>
#include <iostream>
// Macro for indexing vertex buffer
#define BUFFER_OFFSET(i) ((char *)NULL + (i))
using namespace std;
// Vertex Shader (for convenience, it is defined in the main here, but we will be using text files for shaders in future)
// Note: Input to this shader is the vertex positions that we specified for the triangle.
// Note: gl_Position is a special built-in variable that is supposed to contain the vertex position (in X, Y, Z, W)
// Since our triangle vertices were specified as vec3, we just set W to 1.0.
static const char* pVS = " \n\
#version 330 \n\
\n\
in vec3 vPosition; \n\
in vec4 vColor; \n\
out vec4 color; \n\
\n\
\n\
void main() \n\
{ \n\
gl_Position = vec4(vPosition.x, vPosition.y, vPosition.z, 1.0); \n\
color = vColor; \n\
}";
// Fragment Shader
// Note: no input in this shader, it just outputs the colour of all fragments, in this case set to red (format: R, G, B, A).
static const char* pFS = " \n\
#version 330 \n\
\n\
out vec4 FragColor; \n\
\n\
void main() \n\
{ \n\
FragColor = vec4(1.0, 0.0, 0.0, 1.0); \n\
}";
