包含来自其他文件夹的头文件时出错

我们有多个项目使用一些共同的代码。有些项目有不同的时钟速率。通用代码段之一使用UART。UART相关文件位于.\CudioSerialcom中的目录中，在UART1.C文件中定义BRG：FoSC定义在St.h中的项目文件中：…ProjestProjordNo.固件SR\驱动程序。这两个文件都是项目的一部分。两个目录都包含在Project Pro/Realth/Stand文件夹中。两个目录都包含在ProjtProjts/xC16 GCC中，下拉框中选择“预处理和消息”，C包括DRE。显然，如果我在UART1.C文件中不包括Syt.h，我会得到：“错误：‘FoSC’未被删除”。但是当我包含Syt.h时，我得到了一个奇怪的（似乎不相关的）第一个错误如下：“从……/SRC/驱动程序/系统中包含的文件。h：30:0，从….. /…/No./SerialCu/UART1.C：51：…///…/No./Serialcom／Serialcom。h：18:20:错误：预期''”在“TopRunt”“系统”h之前明显使用EL WHE。在项目中，没有这个“FoSC”的要求，它没有问题地建立起来。查看论坛帖子“M77 8606 .ASPX”（抱歉，我还不允许链接），我想它与目录结构有关。有没有办法让这个工作？



      以下为原文

    We have multiple projects using some common code.  Some of the projects have different clock rates.  One of the common code sections uses the UART.  The UART related files are located in the directory:
..CommonSerialCom

To define a BRG in the uart1.c file I have:
    // Baud Rate = 115200;
    U1BRG = (int)((FOSC / (2 * 4 * 115200)) - 1);

FOSC is defined in the project files in system.h located in the directory:
..ProjectsProjectNamefirmwaresrcdrivers

Both files are part of the project.  Both directories are included in Project Proerties/General/Source Folders. Both directories are included in Project Properties/XC16-gcc, Drop down box select "Preprocessing and messages", C include dirs.

Obviously, if I don't include system.h in the uart1.c file I get: "error: 'FOSC' undelared".  But when I include system.h, I get a weird (seemingly unrelated) first error as follows.

"In file included from ../src/drivers/system.h:30:0,
                 from ../../../Common/SerialCom/uart1.c:51:
../../../Common/SerialCom/SerialCom.h:18:20: error: expected ')' before 'toPrint'"


System.h is obviously used elsewhere in the project and without this "FOSC" requirement it builds without issue.  After looking at forum post "m778606.aspx" (Sorry, I'm not allowed to link yet) I think it has to do with the directory structure.  Is there a trick to get this to work?

很显然，您在投影的其他地方使用了System.h，没有人能看到您所做的。这不是目录错误，而是代码错误。您看过SerialCom.h中的第18行吗？什么是托普林特？它是宏吗？前面有什么问题？前面系统中包含的标题有问题吗？h



      以下为原文

    System.h is obviously used elsewhere in the project 
only obvious to you, noone can see what you did
 
That is not a directory error it is a code error.
Did you look at line 18 in SerialCom.h? what is 'toPrint?  Is it a Macro?  what is immediately before it.
Is there a problem with the header included before system.h

可以。。。我不想张贴更多的帖子，因为帖子已经长了。我会尝试给予更多，但这是一个好规模的项目，我只想给尽可能多的信息，因为需要。我在找人说……”是的，我遇到过这样的问题。“St.h在项目中的其他12个文件中使用。如果我用常量替换FOSC（在原始文章中）并将system.h从uart1.c中的include中移除，那么项目构建得很好。system.h中的第29-31行：“SerialComOn”被定义。uart1.c中的第47-52行：以及SerialCom.h的整个文件：



      以下为原文

    Okay... I was trying to not post more than is needed, because the post was already getting long.  I'll try giving more, but this is a good sized project and I only want to give as much info as is needed.  I was fishing for someone to say... "yeah I've had a problem like that."
 
system.h is used in 12 other files in the project.  If I replace FOSC (in original post) with a constant and remove the system.h from the include in uart1.c then the project builds fine.
 
Line 29-31 in system.h:
#ifdef SerialComOn
    #include "SerialCom.h"
#endif
"SerialComOn" is defined.
 
Line 47-52 in uart1.c:
/**
  Section: Included Files
 */

#include "system.h"
#include "uart1.h"
 
And the entire file of SerialCom.h:
/*
 * File:   SerialCom.h
 * Author: A Wolfe
 *
* Created on March 2, 2016, 5:42 PM
 */

#ifndef SERIALCOM_H
#define    SERIALCOM_H

#ifdef    __cplusplus
extern "C" {
#endif
    
void SerialCom_Initialize (void);
void PrintString(char *String);
void PrintDecimal(int toPrint);
void PrintHex(BYTE toPrint);
void PrintHex16(int toPrint);

#ifdef    __cplusplus
}
#endif

#endif    /* SERIALCOM_H */

谢谢。在这个作用域中没有定义字节。我忽略了它。

    Thanks.  BYTE was not defined in this scope.  I had overlooked it.
