警告：「結構GLUquadric」

Question

的提前聲明我得到以下

x.cpp: In member function ‘X’: 
x.cpp:153:10: warning: possible problem detected in invocation of delete operator: 
x.cpp:146:19: warning: ‘quadric’ has incomplete type /usr/include/GL/glu.h:271:7: warning: forward declaration of ‘struct GLUquadric’ 
x.cpp:153:10: note: neither the destructor nor the class-specific operator delete will be called, even if they are declared when the class is defined. 

有了這個代碼

146: GLUquadricObj * quadric; 
147: quadric = gluNewQuadric(); 
148: gluQuadricNormals(quadric, GLU_SMOOTH); 
149: gluQuadricTexture(quadric, GL_TRUE); 
150: 
151: gluSphere(quadric, object.radius(), slices, stacks); 
152: 
153: delete quadric; 

我明白爲什麼這樣做，GLUquadricObj事實上是盼着聲明，但

我想避免這個警告。

我想抑制這個唯一函數的警告。

或者通過包含正確的標題解決警告。我在/ usr/include/GL中使用了grep，但沒有找到完整的類型。

我使用Arch Linux的

檯面7.8.2-3

和

GCC 4.5.1-1

Answer 1

GLUquadricObj需要使用被刪除：

gluDeleteQuadric(GLUquadricObj *); 

Answer 2

對於未分配對象的對象，不得使用delete h new。在不瞭解OpenGL的情況下，我相信你必須在這裏使用gluDeleteQuadric。
