Question

我有这个文件：

// File.cpp

int main() {
   FuncToChange(4, 6, 9, 12);
}

现在，我需要获得此行为：

// Config.h

#define FuncToChange($1, $2, $3, $4) NewFunc($1, $3, $4)

// File.cpp

#include "Config.h"

int main() {
   FuncToChange(4, 6, 9, 12);
}

如何在不修改原始“File.cpp”文件的情况下执行此操作，即不显式#include“Config.h”？

是否可以从makefile或IDE强制包含头文件（在本例中为CodeBlocks）？

谢谢！

平台：
CodeBlocks 10.05
GCC / MinGW的
Windows 7

在preprocessor options页面上的GCC页面：

-include file
    Process file as if #include "file" appeared as the first line of the
    primary source file. However, the first directory searched for file is
    the preprocessor's working directory instead of the directory containing
    the main source file. If not found there, it is searched for in the remainder
    of the #include "..." search chain as normal. If multiple -include options
    are given, the files are included in the order they appear on the command line.

如何从CodeBlocks或Makefile强制包含头？
