这是我的程序
#pragma comment(lib, "opengl32.lib")
#pragma comment(lib, "glu32.lib")
#pragma comment(lib, "glut32.lib")
#include "include\Angel.h"
const int NumPoints = 3;
void
init( void )
{
// Specifiy the vertices for a triangle
vec2 vertices[3] = {
vec2( -0.75, -0.75 ), vec2( 0.0, 0.75 ), vec2( 0.75, -0.75 )
};
// Create a vertex array object
GLuint vao[1];
glGenVertexArrays( 1, vao );
glBindVertexArray( vao[0] );
// Create and initialize a buffer object
GLuint buffer;
glGenBuffers( 1, &buffer );
glBindBuffer( GL_ARRAY_BUFFER, buffer );
glBufferData( GL_ARRAY_BUFFER, sizeof(vertices), vertices, GL_STATIC_DRAW );
// Load shaders and use the resulting shader program
GLuint program = InitShader( "vshader21.glsl", "fshader21.glsl" );
glUseProgram( program );
// Initialize the vertex position attribute from the vertex shader
GLuint loc = glGetAttribLocation( program, "vPosition" );
glEnableVertexAttribArray( loc );
glVertexAttribPointer( loc, 2, GL_FLOAT, GL_FALSE, 0,
BUFFER_OFFSET(0) );
glClearColor( 1.0, 1.0, 1.0, 1.0 ); // white background
}
void
display( void )
{
glClear( GL_COLOR_BUFFER_BIT ); // clear the window
glDrawArrays( GL_TRIANGLES, 0, NumPoints ); // draw the points
glFlush();
}
void
keyboard( unsigned char key, int x, int y )
{
switch ( key ) {
case 033:
exit( EXIT_SUCCESS );
break;
}
}
int
main( int argc, char **argv )
{
glutInit( &argc, argv );
glutInitDisplayMode( GLUT_RGBA );
glutInitWindowSize( 512, 512 );
glutCreateWindow( "Red Triangle" );
glewExperimental=GL_TRUE;
glewInit();
init();
glutDisplayFunc( display );
glutKeyboardFunc( keyboard );
glutMainLoop();
return 0;
}
我认为我已经正确安装了glut，freeglut和glew，我已经编辑了链接器，但仍然出错.我在项目和Visual Studio中放入了glut，freeglut和glew文件夹，但它仍然显示该错误.对于我可以编译的第一个项目，现在我使用的是Angle.h，它无法编译
I think I already install glut,freeglut and glew correctly, I already edit my linker but its still error. I put glut, freeglut, and glew folder in my project and in my visual studio but it still show that error. for the first project I can compile, now I'm using Angle.h and it cannot compile
推荐答案
由于您正在使用预处理程序黑客来链接其余库，因此我想您可能想要这样做:
Since you are using pre-processor hacks to link against the rest of your libraries, I imagine you probably want to do this:
#pragma comment(lib, "glew32.lib")
通常，您将使用项目设置来设置链接库，但是许多教程使用预处理器指令，因为它避免了引导用户完成配置Visual Studio项目的工作(每个新版本都不同).
Usually you would use project settings to set up linked libraries, but a lot of tutorials use the pre-processor directive because it avoids having to walk users through configuring Visual Studio projects (which differs with every new version).
