在Xcode 6 for iOS8中显示OES OpenGL语句的错误 [英] Errors showing for OES OpenGL statements in Xcode 6 for iOS8

问题描述

Yosemite中的Xcode 6 iOS SDK 8.0给出了OpenGL ES2代码的错误，该代码在Xcode 5下编译得很好

  GLuint depthStencilRenderbuffer ; 
 glBindRenderbufferOES（GL_RENDERBUFFER_OES，depthStencilRenderbuffer）; 
 glRenderbufferStorageOES（GL_RENDERBUFFER_OES，
 GL_DEPTH24_STENCIL8_OES，
 self.view.bounds.size.width，
 self.view.bounds.size.height）; 
  

产生错误：

第2行：

'glBindRenderBufferOES'的冲突类型

使用未声明的标识符'GL_RENDERBUFFER_OES'

第3行：

包含'glBindRenderBufferOES'的隐式声明在C99中无效

<编辑：好的，我可以通过替换来重新开始工作：

  GLuint depthStencilRenderbuffer; 
 glBindRenderbuffer（GL_RENDERBUFFER，depthStencilRenderbuffer）; 
 glRenderbufferStorage（GL_RENDERBUFFER，
 GL_STENCIL_INDEX8，
 self.view.bounds.size.width，
 self.view.bounds.size.height）; 
  

仍然 - 我不知道为什么需要这种改变，我会更加欣赏一些进一步的见解这是怎么回事。

解决方案

尝试：

  #import< OpenGLES / ES2 / glext.h> 
  

或

  #import< OpenGLES / ES3 / glext.h> 
  

适合我。

没有它，正确处理xco​​de 6 + ios7的app可以找到GL_FALSE和其他..

Xcode 6 iOS SDK 8.0 in Yosemite is giving me errors for OpenGL ES2 code which compiles fine under Xcode 5

GLuint depthStencilRenderbuffer;
glBindRenderbufferOES(GL_RENDERBUFFER_OES, depthStencilRenderbuffer);
glRenderbufferStorageOES(GL_RENDERBUFFER_OES,
                         GL_DEPTH24_STENCIL8_OES,
                         self.view.bounds.size.width,
                         self.view.bounds.size.height);

Generates errors:

line 2:

Conflicting types for 'glBindRenderBufferOES'

Use of undeclared identifier 'GL_RENDERBUFFER_OES'

line 3:

implicit declaration of contain 'glBindRenderBufferOES' is invalid in C99

Edit: OK, I can get things working again by substituting:

GLuint depthStencilRenderbuffer;
glBindRenderbuffer(GL_RENDERBUFFER, depthStencilRenderbuffer);
glRenderbufferStorage(GL_RENDERBUFFER,
                      GL_STENCIL_INDEX8,
                      self.view.bounds.size.width,
                      self.view.bounds.size.height);

Still - I don't know why this change is needed and I'd appreciate some further insight as to what's going on here.

解决方案

Try:

#import <OpenGLES/ES2/glext.h>

or

#import <OpenGLES/ES3/glext.h>

works for me.

Without it, app which correctlyworking on xcode 6 + ios7 can find GL_FALSE and others..
