c++ - boost_regex 库的静态链接

Question

我在 CentOS 5.2 环境下使用 boost_regex library(ver 1.33.1) 写了一个程序。我用 yum 命令安装了 Boost 库。

我的程序接受使用以下这组选项进行编译:

g++ -O2 -g -lm -lboost_regex main.cpp

但是，这组选项出错了:

g++ -static -O2 -g -lm -lboost_regex main.cpp

错误代码如下:

编辑:删除 -g 选项没有帮助。

hmjd 的回答是正确的。

实际上，同时，我从一个日本网站上得到了我的解决方案。

根据回答，正确的命令如下:

g++ -static -O2 main.cpp -lm -lboost_regex -lpthread

hmjd是这么说的
