libboost_regex未编译

Question

我正试图在我的c++代码中编译一些正则表达式。

我已经运行了ln -s /usr/lib64/libboost_regex.so.1.53.0 /usr/lib/libboost_regex.so，以便正确地链接它。

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

我得到以下错误：

我认为这仍然意味着编译器对libboost_regex文件有问题。

这是我试图运行的代码示例：

#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);
}

有人能告诉我我哪里出错了吗？我只是尝试使用boost lib，以便能够使用正回溯。

谢谢，丹尼尔

Answer 1

看起来，您编译并链接到了两个不同版本的boost：

1. 一个来自/usr/include/boost和/usr/lib64/。
2. 另一个来自/usr/local/include/boost和/usr/local/lib。

这可能是导致链接器错误的原因。

我已经运行了ln -s /usr/lib64/libboost_regex.so.1.53.0 /usr/lib/libboost_regex.so，以便正确地链接它。

/usr目录由您的系统包管理器管理，手动管理文件会导致麻烦。别那么做。

可能发生的情况是，您没有安装boost-devel或libboost-all-dev，也没有在系统中调用任何boost开发包。该包提供了要链接的标题和库。(手动创建的链接可能会阻止包的安装。)
