尝试通过Eclipse

尝试通过Eclipse-AVR使用Arduino的HardwareSerial(Trying to use Arduino's HardwareSerial via Eclipse-AVR)

我正在尝试移植现在随Arduino 1.0 IDE一起提供的硬件串行库。我正在编译ATMega2560处理器并使用一个简单的“Hello World”示例测试Arduino USART库“HardwareSerial”，但我留下了这个奇怪的声音错误。

它告诉我，我是： attempt[ing] to use poisoned "SIG_USART0_RECV" ......我以前从未听说过这样的错误。我试图找出它的定义，eclipse给了我这个：

#define SIG_USART0_RECV _VECTOR(25) ，它位于iomxx0_1.h 。

然后从那里_VECTOR(n)通过#define _VECTOR(N) __vector_ ## N重定向到__vector_25 。但那些是在系统路径中，我认为它们仍然有效，因为当前的Arduino库仍然使用它们。

为什么他们会毒害自己的定义？在尝试编译项目之前，是否需要声明其他内容？

编辑：

我在iomxx0_1.h发现了毒药，说明： #pragma GCC poison SIG_USART0_RECV 。那他们为什么要毒害这个呢？

I am trying to port over the Hardware Serial library that now comes with the Arduino 1.0 IDE. I am compiling on a ATMega2560 processor and testing the Arduino USART library "HardwareSerial" with a simple "Hello World" example, but I am left with this strange sounding error.

It tells me that I am: attempt[ing] to use poisoned "SIG_USART0_RECV"... I have never heard of such an error before. I tried to find out what it was defined to and eclipse gave me this:

#define SIG_USART0_RECV _VECTOR(25) which was found in iomxx0_1.h.

Then from there _VECTOR(n) redirected to __vector_25 via #define _VECTOR(N) __vector_ ## N. But those are in system paths, and I assume they are still valid since the current Arduino libraries still uses them.

Why would they poison their own defines? Do I need to declare something else before I try compiling the project?

Edit:

I found the poison in iomxx0_1.h stating: #pragma GCC poison SIG_USART0_RECV. So why would they poison this?
