我刚刚使用 sudo port install boost 安装了来自macports的boost 1.42.0。

I just installed boost 1.42.0 from macports using sudo port install boost.

一切都很好。现在我有一个项目，我试图使用makefile。一切构建正常，直到它涉及到需要boost库的文件。

Everything worked fine. Now I have a project that I'm trying to build using a makefile. Everything builds fine until it comes to the file that needs the boost library.

它说： src / graph.h：20：42：错误：boost / graph / adjacency_list.hpp：没有这样的文件或目录

It says: src/graph.h:20:42: error: boost/graph/adjacency_list.hpp: No such file or directory

该文件实际位于两个地方： /opt/local/include/boost/graph/adjacency_list.hpp 和 /opt/local/var/macports/software/boost/1.42.0_0/opt/local/include/boost/graph/adjacency_list.hpp

That file is actually located in two places: /opt/local/include/boost/graph/adjacency_list.hpp and /opt/local/var/macports/software/boost/1.42.0_0/opt/local/include/boost/graph/adjacency_list.hpp

在文件src / graph.h中，它正在寻找boost / graph / adjacency_list.hpp，include语句在这里： ＃include< boost / graph /adjacency_list.hpp>

In the file src/graph.h where it's looking for boost/graph/adjacency_list.hpp, the include statement is here: #include<boost/graph/adjacency_list.hpp>

如何使这项工作？

推荐答案

您需要告诉编译器Boost的基本目录。您可以使用编译器的 -I 命令行选项：

You need to tell the compiler the base directory where Boost is intalled. You can do that with the compiler's -I command line option:

g++ -I/opt/local/include ...
