mal*_*yeb 5 c++ regex boost boost-regex
我试图使用Boost库但是我失败了,看到我的代码:
#include "listy.h"
#include <boost/regex.hpp>
using namespace boost;
ListyCheck::ListyCheck() {
}
ListyCheck::~ListyCheck() {
}
bool ListyCheck::isValidItem(std::string &__item) {
regex e("(\\d{4}[- ]){3}\\d{4}");
return regex_match(__item, e);
}

当我尝试编译它时,我得到了这些消息:
/usr/include/boost/regex/v4/regex_match.hpp:50:未定义引用`boost :: re_detail :: perl_matcher <__ gnu_cxx :: __ normal_iterator,std :: allocator >>,std :: allocator,std :: allocator >>>>>,boost :: regex_traits>
::比赛()'
/usr/include/boost/regex/v4/basic_regex.hpp:425:未定义的引用`boost :: basic_regex>

等等...
