Opengl superbible示例compliation错误源代码：绘制三角形库

Question

我是OpenGL的新手，我现在正在尝试示例，我已经正确地包含了所有的库，但似乎还有些东西不正确。

两个库：freeglut_static.lib gltools.lib包含在项目中。

这是代码：

// Triangle.cpp 
// Our first OpenGL program that will just draw a triangle on the screen. 
#include <GLTools.h> // OpenGL toolkit 
#include <GLShaderManager.h> // Shader Manager Class 
#ifdef __APPLE__ 
#include <glut/glut.h> // OS X version of GLUT 
#else 
#define FREEGLUT_STATIC 
#include <GL/glut.h> // Windows FreeGlut equivalent 
#endif 
GLBatch triangleBatch; 
GLShaderManager shaderManager; 
/////////////////////////////////////////////////////////////////////////////// 
// Window has changed size, or has just been created. In either case, we need 
// to use the window dimensions to set the viewport and the projection matrix. 
void ChangeSize(int w, int h) 
{ 
    glViewport(0, 0, w, h); 
} 
/////////////////////////////////////////////////////////////////////////////// 
// This function does any needed initialization on the rendering context. 
// This is the first opportunity to do any OpenGL related tasks. 
void SetupRC() 
{ 
    // Blue background 
    glClearColor(0.0f, 0.0f, 1.0f, 1.0f); 
    shaderManager.InitializeStockShaders(); 
    // Load up a triangle 
    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(); 
} 
/////////////////////////////////////////////////////////////////////////////// 
// Called to draw scene 
void RenderScene(void) 
{ 
    // Clear the window with current clearing color 
    glClear(GL_COLOR_BUFFER_BIT | GL_DEPTH_BUFFER_BIT | GL_STENCIL_BUFFER_BIT); 
    GLfloat vRed[] = { 1.0f, 0.0f, 0.0f, 1.0f }; 
    shaderManager.UseStockShader(GLT_SHADER_IDENTITY, vRed); 
    triangleBatch.Draw(); 
    // Perform the buffer swap to display the back buffer 
    glutSwapBuffers(); 
} 

/////////////////////////////////////////////////////////////////////////////// 
// Main entry point for GLUT based programs 
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(“Triangle”); 
    glutReshapeFunc(ChangeSize); 
    glutDisplayFunc(RenderScene); 
    GLenum err = glewInit(); 
    if (GLEW_OK != err) { 
     fprintf(stderr, “GLEW Error: %s\n”, glewGetErrorString(err)); 
     return 1; 
    } 
    SetupRC(); 
    glutMainLoop(); 
    return 0; 
} 

错误形式交往给出：

Answer 1

你有你的输入库？在项目/属性/链接器/输入/附加依赖

Answer 2

unresolved external symbol _glewGetErrorString 

这意味着编译器不会在您的环境中找到glew32库。尝试安装它并确保它在LDPATH中，以便您的编译器可以看到它。
