Question

我正在尝试在我的C ++代码中编译一些正则表达式。

我已经跑过ln -s /usr/lib64/libboost_regex.so.1.53.0 /usr/lib/libboost_regex.so 这样才能正确链接。

我正在运行的命令是：g++-4.9 -std=c++11 -O2 -Wall -I/usr/local/include/boost load_and_search.cpp -o bkSearch -L/usr/local/lib/ /usr/local/lib/libboost_serialization.a -lboost_regex

我遇到以下错误：

我相信这仍然意味着编译器在libboost_regex文件方面存在问题

这是我要运行的代码示例：

#include <iostream>
#include <string>
#include <map>
#include <vector>
#include <fstream>
#include <sstream>
#include <iterator>
#include <cstdlib>
#include <cstring>
#include <chrono>
#include <iostream>
#include <boost/regex.hpp>
#include <regex>
#include "BKTree.h"
#include <algorithm>
#include <locale>

#include <boost/archive/text_oarchive.hpp>
#include <boost/archive/text_iarchive.hpp>
#include <boost/lexical_cast.hpp>
#include <boost/algorithm/string.hpp>

using namespace std::chrono;

void prematch(std::vector<std::vector<std::string> > &parsedCsv, int &i, boost::regex &digitReg, boost::regex &flatNumReg)
{
    boost::regex digitReg ("^[^\\d]*(\\d+)");  
    boost::regex flatNumReg ("(?<=\\bflat\\s|\\bfl\\s|\\bapartment\\s)([a-z0-9]{1,})");  
    std::string add1 (parsedCsv[i][0]);
    boost::smatch digitMatch;       
    boost::smatch typeMatch;
    boost::regex_search (add1,digitMatch,digitReg);
    std::string add1String = boost::lexical_cast<std::string>(parsedCsv[i][0]);
    boost::regex_search (add1,typeMatch,flatNumReg);
}

有人可以指出我哪里出问题了吗？我只是在尝试使用boost lib，以便能够使用肯定的回溯。

谢谢，丹尼尔

您似乎在针对两个不同版本的boost进行编译和链接：

/usr/include/boost和/usr/lib64/中的一个。
另一个来自/usr/local/include/boost和/usr/local/lib的人。

这可能是您收到链接器错误的原因。

我已经运行ln -s /usr/lib64/libboost_regex.so.1.53.0 /usr/lib/libboost_regex.so以便正确链接。

/usr目录由系统软件包管理器管理，在那里手动管理文件会导致麻烦。不要那样做。

可能发生的情况是您没有安装boost-devel或libboost-all-dev或在系统中调用任何boost开发包。该软件包提供了标题和要链接的库。（您手动创建的链接可能会阻止软件包的安装。）

libboost_regex无法编译
