XC8 Printf不会调用putch

Heloi有一个类似于线程XC8 Primtf不调用PutCH的问题（http://www. McCyc.com /论坛/ M982444 .ASPX）。在我的代码中，我调用PrtTf函数将一些字符写入RS232终端。我已经实现了PoCH函数，以预先定义的波特率将预定义端口设置为高或低。我在不同的图片中使用了很多不同的图片。现在我想用PIC18F46K40（XC8V1.41）来使用它，但是PrtTF不调用PoCH函数。我已经检查了EBTRX配置位，这是前面提到的线程中的问题。看起来这些设置是可以的。我使用了“配置位”生成器，并确保在自己的代码中没有On/OFF定义。以确保我已经用“0”和“1”替换了我的“语法”中的“开/关”。现在我还不知道下一步该怎么办。编译器设置中有什么会产生影响吗？

    Hello

I've got a problem similar to the one in the thread 'XC8 Printf doesn't call putch' (http://www.microchip.com/forums/m982444.aspx).

In my code I call the printf function to write some characters to a RS232 terminal. I've implemented the putch function to set a predefined port to high or low at a predefined baud rate. I've used this implementation a lot in various projects with different PICs.
Now I want to use it with the PIC18F46K40 (XC8 v1.41) but the printf doesn't call the putch function. I've checked the EBTRx config bits as that was the problem in the thread mentioned earlier. It looks like those settings are ok. I've used the 'Configuration Bits' generator and made sure I have no #define ON / OFF in my own code. To make sure I've replaced the ON/OFF's in my #pragma with '0' and '1'. Still no call of putch.

Now I am a bit at a loss as to what to do next. Is there anything in the compiler settings that could have an influence?
