Mac上的OpenGL C ++构建失败' GL / glut.h'文件未找到

标签: c++ xcode macos opengl glut

尝试使用xCode在OSX Yosemite上运行示例OpenGL C ++程序。

在运行程序时,我得到了GL / glut.h'找不到文件截图:

'GL/glut.h' file not found

但是,我在项目中有glut.h标题:

glut.h header in the project

在另一个论坛上,我读到它应该是' GLUT / glut.h'所以我做了,但得到了以下信息:

GLUT/glut.h

如何配置带有C ++的OpenGL,我需要做什么?

这是我试图运行的代码。如果我可以运行这个,那么我应该准备好一切:

#include <GLUT/glut.h>
#include <math.h>
//#include <stdlib.h>

const double TWO_PI = 6.2831853;

/*  Initial display-window size.  */
GLsizei winWidth = 400, winHeight = 400;
GLuint regHex;

class screenPt
{
private:
    GLint x, y;

public:
    /*  Default Constructor: initializes coordinate position to (0, 0).  */
    screenPt ( )  {
        x = y = 0;
    }

    void setCoords (GLint xCoord, GLint yCoord)  {
        x = xCoord;
        y = yCoord;
    }

    GLint getx ( ) const  {
        return x;
    }

    GLint gety ( ) const  {
        return y;
    }
};

static void init (void)
{
    screenPt hexVertex, circCtr;
    GLdouble theta;
    GLint k;

    /*  Set circle center coordinates.  */
    circCtr.setCoords (winWidth / 2, winHeight / 2);

    glClearColor (1.0, 1.0, 1.0, 0.0);   //  Display-window color = white.

    /*  Set up a display list for a red regular hexagon.
     *  Vertices for the hexagon are six equally spaced
     *  points around the circumference of a circle.
     */
    regHex = glGenLists (1);   //  Get an identifier for the display list.
    glNewList (regHex, GL_COMPILE);
    glColor3f (1.0, 0.0, 0.0);   //  Set fill color for hexagon to red.
    glBegin (GL_POLYGON);
    for (k = 0; k < 6; k++) {
        theta = TWO_PI * k / 6.0;
        hexVertex.setCoords (circCtr.getx ( ) + 150 * cos (theta),
                             circCtr.gety ( ) + 150 * sin (theta));
        glVertex2i (hexVertex.getx ( ), hexVertex.gety ( ));
    }
    glEnd ( );
    glEndList ( );
}

void regHexagon (void)
{
    glClear (GL_COLOR_BUFFER_BIT);

    glCallList (regHex);

    glFlush ( );
}

void winReshapeFcn (int newWidth, int newHeight)
{
    glMatrixMode (GL_PROJECTION);
    glLoadIdentity ( );
    gluOrtho2D (0.0, (GLdouble) newWidth, 0.0, (GLdouble) newHeight);

    glClear (GL_COLOR_BUFFER_BIT);
}

void main (int argc, char** argv)
{
    glutInit (&argc, argv);
    glutInitDisplayMode (GLUT_SINGLE | GLUT_RGB);
    glutInitWindowPosition (100, 100);
    glutInitWindowSize (winWidth, winHeight);
    glutCreateWindow ("Reshape-Function & Display-List Example");

    init ( );
    glutDisplayFunc (regHexagon);
    glutReshapeFunc (winReshapeFcn);

    glutMainLoop ( );
}

当您将其更改为'GLUT / glut.h`时,它会正确找到标题。不幸的是,现在您收到有关已弃用函数的所有警告消息。

有关已弃用的功能消息的修正,请参阅xcode 5 deprecation warning about glut functionsGlut deprecation in Mac OSX 10.9, IDE: QT Creator

您还有一条错误消息,指出您的main函数需要返回一个int。这将阻止您的代码编译,而不是警告。

修改 您应该将main函数更改为返回类型为int。

int main(int argc, char *argv[])
{
  /* code */
  return 0;
}

有些编译器会接受void作为main的返回类型,但这是一个非标准扩展。

尝试#include <GLUT/glut.h> 因为框架的链接名称是GLUT。
