为什么我无法在 iPhone 上编译引用 vImage 库的代码？

我正在尝试在我的代码中包含基于 vImage 的功能。但编译失败 - 它甚至似乎根本无法识别函数/变量。

但与此同时，基于 vDSP 的代码似乎运行良好。此外，代码在模拟器中编译，但在设备中失败。

示例代码（失败）如下所示

#import "test.h"
#include <Accelerate/Accelerate.h>

@implementation test 

-(void) test1{
  DSPComplex d ={1.0, 2.0};
  d;
  vImagePixelCount x = 3;
  x;
}
@end

，DSPComplex（基于 DSP 的代码）在同一框架中工作正常，而 vImagePixelCount（基于 vImage 的代码）则失败。有人能帮我解决这个问题吗？ iOS4 中不包含 vImage 吗？

我在设备中使用iOS4.2。

I am trying to include vImage based functionality in my code. But compile fails - it doesnt even seem to recognize the functions/variables at all.

But at the same time vDSP based code seems to work fine. Also, the code compiles in simulator but fails in the device.

A sample code (which fails) is as follows

#import "test.h"
#include <Accelerate/Accelerate.h>

@implementation test 

-(void) test1{
  DSPComplex d ={1.0, 2.0};
  d;
  vImagePixelCount x = 3;
  x;
}
@end

Here, DSPComplex which is DSP based code, in the same framework - works fine, while vImagePixelCount - which is vImage based code - it fails. Can anyone help me on this? Is vImage not included in iOS4 ?

I am using iOS4.2 in the device.
