, поэтому я слежу за "OpenGL superbible 5" и столкнулся с еще одной проблемой:
Я пытаюсь использовать GLTools.h, GLShaderManager, math3d.h и т. Д., Чтобы получить пример кода для книги, только что из Google Code, но
Все, что я получаю, это пустое белое окно.
Вот код, который я запускаю:
// Objects.cpp
// OpenGL SuperBible, Chapter 4
// Demonstrates GLTools built-in objects
// Program by Richard S. Wright Jr.
#include <GL/glew.h>
#include <GLTools.h> // OpenGL toolkit

#include <GLFrame.h>
#include <GLFrustum.h>
#include <GLBatch.h>
#include <GLGeometryTransform.h>
#include <math.h>
#ifdef __APPLE__
#include <glut/glut.h>
#else
#define FREEGLUT_STATIC

И вот ошибки, появляющиеся в текстовом поле вывода в VS2010:
Множество файлов PDB не найдено (но я сомневаюсь, что это проблема)
