Question

我正在尝试在现有应用程序上运行一个名为crest的工具。我的第一个目标应用程序是Apache。输出（如下所示）表示找不到某些头文件。它们位于源文件夹中的其他目录中。其中一个是\ httpd-2.2.14 \ srclib \ apr \ include。我不想更改apache的源代码，因为我想对Apache中的大量文件运行此命令，然后将相同的技术应用于其他几个应用程序。

我的问题是：

1）我怎样才能这样做，只要找到这些引用的包含文件，它就会找到它们所在的正确目录并将使用它。我可以定义目录。有朋友提到了改变命令行输入或构建环境变量的事情吗？

其他想法/建议将不胜感激。

谢谢大家。

运行波峰的命令是： ../bin/crestc ../../httpd-2.2.14/server/request.c -dfs

我得到以下输出：

您可以设置C_INCLUDE_PATH环境变量（使用:分隔多个路径）：

 export C_INCLUDE_PATH=/path/to/include/files:/path/to/more/include/files

自动引用不同目录中的头文件
