我所知道的是,这可能是一个与软件编写时不同的boost版本(我不知道是哪个版本,我现在使用的是1.53)。但是从代码来看,它似乎仍然可以工作。此外,我正在使用这个boost版本的头文件,因此如果函数签名发生了更改,编译器应该已经开始抱怨了


我怎样才能把这个链接到link?我遗漏了什么吗?

链接器开关顺序错误<代码>生成尝试执行以下操作:

g++ -lboost_regex -lboost_iostreams -o main main.o
这是实际可行的(至少在gcc 4.8.1中是这样):

因此,要修复编译错误,应使用以下内容替换Makefile中的第6行:

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

非常感谢你的提示。顺序对于cmake(目标链接库)来说非常重要,在读到这篇文章之前,我一直在努力链接我的程序。我对这个主题有一点疑问。您是否知道如何使用该库进行一对一和多对多查询?我使用电脑有困难it@Alex如果您有新问题,请使用“提问”功能。可能重复
g++ -o main main.o -lboost_regex -lboost_iostreams
    $(CXX) -o $@ $^ $(LIBS) $(LINK)
