无法链接 Boost 正则表达式

我目前正在尝试编译一个KIT 的收缩层次实现 http://algo2.iti.kit.edu/english/routeplanning.php这需要 Boost::Regex。提供的 Makefile 已经确保（并且我还手动仔细检查了这一点）g++ 是随-lboost_regex转变。如果未安装该库，g++ 会抱怨。

因此，我从包源安装了该库并尝试再次编译。这次我收到了大量有关 Boost::Regex 的链接器错误。这是一个简短的摘录：

这看起来很像编译器根本没有找到该库。事实上，当我不提供-lboost_regex切换输出保持不变（我对其进行了哈希处理）。

但是，使用以下命令运行链接器-Wl,--verbose按照中的建议进行切换nuwen MinGW + Boost-链接 boost_regex 时出错 https://stackoverflow.com/questions/7950038/nuwen-mingw-boost-error-linking-boost-regex/7950281#7950281显示已找到该库：

attempt to open /usr/lib/gcc/x86_64-linux-gnu/4.8/../../../../lib/libboost_regex.so succeeded
-lboost_regex (/usr/lib/gcc/x86_64-linux-gnu/4.8/../../../../lib/libboost_regex.so)

我所知道的是，这可能是一个与软件编写时不同的 boost 版本（我不知道是哪个。我现在使用的是 1.53。）但从查看代码来看，它似乎仍然可以工作。另外，我正在使用此 boost 版本中的标头，因此如果函数签名已更改，编译器应该已经抱怨。

我怎样才能得到这个链接？我错过了什么吗？

链接器开关的顺序错误。make尝试这样做：

g++ -lboost_regex -lboost_iostreams -o main main.o

这是实际有效的（至少对于 gcc 4.8.1）：

g++ -o main main.o -lboost_regex -lboost_iostreams

因此，要修复编译错误，您应该将 Makefile 中的第 6 行替换为以下内容：

    $(CXX) -o $@ $^ $(LIBS) $(LINK)
