Funkcja której z której nie korzystam sprawia problem

Witam, czytam książkę "OpenGL księga eksperta wydanie 5" z racji tego, że już wcześniej łyknąłem podstawowych podstaw OpenGLa, to początkowe programy są dla mnie zrozumiałe, lecz problem jest w tym, że w książce jest przedstawiony nowy standard i klasa GLBatch sprawia mi zawód już w momencie wywołania konstruktora. Może ktoś wie w czym tkwi problem?

#include <GLTools.h>
#include <GLShaderManager.h>

#ifdef __APPLE__
#include <glut/glut.h>
#else
#define FREEGLUT_STATIC
#include <GL\glut.h>
#endif

GLBatch triangleBatch;
GLShaderManager shaderManager;

void ChangeSize(int w, int h)
{
	glViewport(0, 0, w, h);
}

void SetupRC()
{
	glClearColor(0.0f , 0.0f, 1.0f, 1.0f);

	shaderManager.InitializeStockShaders();

	GLfloat vVerts[] = {	-0.5f, 0.0f, 0.0f,
							0.5f, 0.0f, 0.0f,
							0.0f, 0.5f, 0.0f	};

	triangleBatch.Begin(GL_TRIANGLES, 3);
	//triangleBatch.CopyVertexData3f(vVerts);
	triangleBatch.End();
}

void RenderScene()
{
	glClear(GL_COLOR_BUFFER_BIT | GL_DEPTH_BUFFER_BIT | GL_STENCIL_BUFFER_BIT);

	GLfloat vRed[] = {	1.0f, 0.0f, 0.0f, 0.0f	};
	shaderManager.UseStockShader(GLT_SHADER_IDENTITY, vRed);
	triangleBatch.Draw();

	glutSwapBuffers();
}

int main(int argc, char* argv[])
{
	gltSetWorkingDirectory(argv[0]);

	glutInit(&argc, argv);
	glutInitDisplayMode(GLUT_DOUBLE | GLUT_RGBA | GLUT_DEPTH | GLUT_STENCIL);
	glutInitWindowSize(800, 600);
	glutCreateWindow("Trójkąt");
	glutReshapeFunc(ChangeSize);
	glutDisplayFunc(RenderScene);

	GLenum err = glewInit();
	if(GLEW_OK != err)
	{
		fprintf(stderr, "Błąd GLEW: %s\n", glewGetErrorString(err));
		return 1;
	}

	SetupRC();

	glutMainLoop();
	return 0;
}

a problem wyskakuje mi w pliku GLBatch.cpp przy funkcji pogrubionej
