【问题描述】：

我是使用 Boost C++ 库的新手，我正在尝试编译此处给出的正则表达式示例代码 (http://www.boost.org/doc/libs/1_46_1/more/getting_started/unix- variables.html#link-your-program-to-a-boost-library)

这是我得到的输出：

不幸的是，我有限的知识意味着我不太明白这一切意味着什么。有人可以解释一下吗？非常感谢 ：） -技术

【参考方案1】：

g++ -I /boost/include/ src/main.cpp -o main -L/boost/lib/ -lboost_regex -lpthread -static
                                                                        ^^^^^^^^^

【讨论】：

哦，谢谢！对于使用 Boost 库的任何应用程序，我是否需要 libpthread？我觉得我必须多读一些文档...感谢您的帮助:)

@Technosites：boost 的某些部分依赖于 pthread，所以这取决于你使用什么。
