Question

关于用OpenGL绘制三维图的问题 以下代码为显示一立方体

#include <windows.h>
#include <gl/gl.h>
#include <gl/glu.h>
#include <gl/glaux.h>
void myinit(void);
void CALLBACK myreshape(GLsizei w,GLsizei h);
void CALLBACK display(void);
void myinint(void)
{
glClearColor(0.0,0.0,0.0,0.0);
}
void CALLBACK display(void)
{
glClear(GL_COLOR_BUFFER_BIT);
glColor4f(0.2,0.6,1.0,1.0);
glRotatef(60.0,1.0,1.0,1.0);
auxWireCube(1.0);
glFlush();
}
void CALLBACK myreshape(GLsizei w,GLsizei h)
{
glViewport(0,0,w,h);
}
void main(void)
{
auxInitDisplayMode(AUX_SINGLE|AUX_RGBA);
auxInitPosition(0,0,400,400);
auxInitWindow("sample");
myinit();
auxReshapeFunc(myreshape);
auxMainLoop(display);
}

有一以下错误23.obj : error LNK2001: unresolved external symbol "void __cdecl myinit(void)" (?myinit@@YAXXZ)
Debug/asd.exe : fatal error LNK1120: 1 unresolved externals
执行 link.exe 时出错.

Answer 1

void myinit(void);
void myinint(void)
声明和定义的名称不一样
{
glClearColor(0.0,0.0,0.0,0.0);
}
