我正在尝试在Visual Studio 2013中测试一些示例代码。
如果我只使用glut.h和gl.h中的函数,它可以成功构建:
#include <stdlib.h>
#include <math.h>
#include <stdio.h>
#include <glut.h>
static int year = 0, spin = 0, day = 0;
static GLint fogMode;
const int n = 100;
const GLfloat R = 1.0f;
const GLfloat Pi = 3.1415926536f;
void init(void)
{
GLfloat position[] = { 0.5, 0.5, 3.0, 0.0 };
glEnable(GL_DEPTH_TEST);
glLightfv(GL_LIGHT0, GL_POSITION, position);
glEnable(GL_LIGHTING);
glEnable(GL_LIGHT0);
{
GLfloat mat[3] = { 0.1745, 0.01175, 0.01175 };
glMaterialfv(GL_FRONT, GL_AMBIENT, mat);
mat[0] = 0.61424; mat[1] = 0.04136; mat[2] = 0.04136;
glMaterialfv(GL_FRONT, GL_DIFFUSE, mat);
mat[0] = 0.727811; mat[1] = 0.626959; mat[2] = 0.626959;
glMaterialfv(GL_FRONT, GL_SPECULAR, mat);
glMaterialf(GL_FRONT, GL_SHININESS, 0.6*128.0);
}
glEnable(GL_FOG);
{
GLfloat fogColor[4] = { 0.5, 0.5, 0.5, 1.0 };
fogMode = GL_EXP;
glFogi(GL_FOG_MODE, fogMode);
glFogfv(GL_FOG_COLOR, fogColor);
glFogf(GL_FOG_DENSITY, 0.35);
glHint(GL_FOG_HINT, GL_DONT_CARE);
glFogf(GL_FOG_START, 1.0);
glFogf(GL_FOG_END, 5.0);
}
glClearColor(0.5, 0.9, 0.9, 1.0);
}
void display(void)
{
glClear(GL_COLOR_BUFFER_BIT | GL_DEPTH_BUFFER_BIT);
glColor3f(0.0, 1.0, 1.0);
glPushMatrix();
glutSolidSphere(1.0, 20, 16);
glRotatef(spin, 0.0, 1.0, 0.0);
glTranslatef(2.0, 1.0, 0.0);
glRotatef(spin, 1.0, 0.0, 0.0);
glRectf(0.1, 0.1, 0.5, 0.5);
glColor3f(0.0, 0.0, 1.0);
glutWireSphere(0.2, 8, 8);
glColor3f(1.0, 0.0, 0.0);
glTranslatef(2.0, 1.0, 0.0);
glRotatef(2 * spin, 0.0, 1.0, 0.0);
glutSolidSphere(0.5, 16, 8);
glPopMatrix();
glutSwapBuffers();
}
void spinDisplay(void)
{
spin = spin + 2;
if (spin > 360)
spin = spin - 360;
glutPostRedisplay();
}
void mouse(int button, int state, int x, int y)
{
switch (button)
{
case GLUT_LEFT_BUTTON:
if (state == GLUT_DOWN)
glutIdleFunc(spinDisplay);
break;
case GLUT_MIDDLE_BUTTON:
if (state == GLUT_DOWN)
glutIdleFunc(NULL);
break;
default:
break;
}
}
void reshape(int w, int h)
{
glViewport(0, 0, (GLsizei)w, (GLsizei)h);
glMatrixMode(GL_PROJECTION);
glLoadIdentity();
//gluPerspective(60.0, (GLfloat)w / (GLfloat)h, 0.5, 20.0);
glMatrixMode(GL_MODELVIEW);
glLoadIdentity();
//gluLookAt(0.0, 10.0, 10.0, 0.0, 0.0, 0.0, 0.0, 1.0, 0.0);
}
int main(int argc, char** argv)
{
glutInit(&argc, argv);
glutInitDisplayMode(GLUT_DOUBLE | GLUT_RGB);
glutInitWindowSize(400, 400);
glutInitWindowPosition(100, 100);
glutCreateWindow("OpengGL Programming");
init();
glutDisplayFunc(display);
glutReshapeFunc(reshape);
glutMouseFunc(mouse);
glutMainLoop();
return 0;
}
但是,如果我想使用来自glu.h的gluPerspective或gluLookAt,它会说:
error LNK2001:unresolved external symbol _gluPerspective@32
error LNK2001:unresolved external symbol _gluLookAt@72
我已将所需目录添加到Include目录和库目录,以及glu32.lib / glaux.lib / glut32.lib / freeglut.lib / glew32.lib / opengl32.lib /链接器下的lib,但它仍然没有工作。
抱歉英语不好,如果我没有清楚地描述问题,请告诉我。
答案 0 :(得分:1)
确保您添加在:(project right click -> properties-> configuration properties->linker->input
这两个库:opengl32.lib;glu32.lib;
你喜欢:
#include <gl/GLU.h>
更多 如果你想使用过剩库和头文件:
在此处添加头文件的路径:
project right click -> properties-> configuration properties->C/C++->gneral->Additional include directories
在此处添加库路径:
project right click -> properties-> configuration properties->linker->general
在此处添加库名称:
project right click -> properties-> configuration properties->linker->input
这对我有用。
