警告：“struct GLUquadric”的前向声明；

我得到以下内容

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.

通过这段代码

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;

，我明白为什么它会这样做，GLUquadricObj 实际上是一个前向声明，但

我想避免这个警告。

我想要么抑制这个单一功能的警告。

或者通过包含正确的标题来解决警告。我在/usr/include/GL中使用了grep，但没有找到完整的类型。

我正在使用 Arch Linux

mesa 7.8.2-3

和

gcc 4.5.1-1

原文

I get the following

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.

With this code

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;

I understand why it does that, GLUquadricObj is in fact a foward declaration, BUT

I want to avoid this warning.

I would like either to suppress this warning for that sole function.

Or resolve the warning by including the right header. I used grep in /usr/include/GL and didn't find the complete type.

I'm using Arch Linux

mesa 7.8.2-3

and

gcc 4.5.1-1
