compiling errors in gl.h

dj_vc

#include <GL/gl.h>
#include <GL/glaux.h>

void main(void)
{
        auxInitDisplayMode(AUX_SINGLE|AUX_RGBA);
        auxInitPosition(0,0,500,500);
        auxInitWindow("simple");
        glClearColor(0.0,0.0,0.0,0.0);
        glClear(GL_COLOR_BUFFER_BIT);
        glColor3f(1.0,0.0,0.0);
        glRectf(-0.5,-0.5,0.5,0.5);
        glFlush();
        _sleep(1000);
}

the trouble is that  fatal errors occured in gl.h when compiled with vc++
errors as follow:
1. error C2144: syntax error : missing ';' before type 'void';
2. error C2501: 'WINGDIAPI' : missing storage-class or type specifiers;
3. fatal error C1004: unexpected end of file found.
who can help me ? maye this program have some wrongs.
os:winxp sp2
lib and include path have no problem.

看样子没包含<windows.h>

huawenguang

#include <windows.h>
#include <GL/gl.h>
#include <GL/glaux.h>

funcman

一些老的文档的例程吧
"标准"的做法是包含一个这样的头

// GLOS.H

// This is an OS specific header file

#include <windows.h>

// disable data conversion warnings

#pragma warning(disable : 4244)     // MIPS
#pragma warning(disable : 4136)     // X86
#pragma warning(disable : 4051)     // ALPHA

thank you all!
but problem hasn't been solved.
the source as below:

#include <windows.h>
#include <GL/gl.h>
#include <GL/glaux.h>
#include <glos.h>

void main(void)
{
auxInitDisplayMode(AUX_SINGLE|AUX_RGBA);
auxInitPosition(0,0,500,500);
auxInitWindow("simple");
glClearColor(0.0,0.0,0.0,0.0);
glClear(GL_COLOR_BUFFER_BIT);
glColor3f(1.0,0.0,0.0);
glRectf(-0.5,-0.5,0.5,0.5);
glFlush();
_sleep(1000);
}

compiled in vc 6.0
error occurred in main.obj,compiling was success!error is in link.
error code as below:

i really don't know that compiling is right but linking is wrong!
who knows reason?help me!!!

dj_vc

thank godness!
i find the solution :
put the sentense as below:
#pragma comment(lib, "opengl32.lib" )
#pragma comment(lib, "glu32.lib" )
#pragma comment(lib, "GLAUX.LIB" )
in your code .all will be right!!!
问个肤浅的问题我试着找了好久,没找到)
谁能告诉怎么在vc里把这些lib库加到工程里去???就是不在程序里用以上那些语句.

dj_vc

in addition,i find another problem,the program above can't be compiling successfully in vc with "win32 application"
who can help me ????
