Question

我最近从PC切换到Mac，从Visual Studio切换到Netbeans，从Java切换到C ++。我试图在我的程序中包含一个boost库，当我构建我的代码时，我收到一个构建错误。有人可以告诉我这个构建错误说的是什么吗？我跟着this post to add the libraries。我也跟着this Boost getting start tutorial，Boost文件夹位于“Netbeans Projects”文件夹中，这是“/Users/Nate/NetBeansProjects/boost_1_60_0/boost”目录。升压文件是否应放在其他地方？

"/usr/bin/make" -f nbproject/Makefile-Debug.mk QMAKE= SUBPROJECTS= .build-conf
"/usr/bin/make"  -f nbproject/Makefile-Debug.mk dist/Debug/GNU-MacOSX/stockapp
mkdir -p dist/Debug/GNU-MacOSX
g++     -o dist/Debug/GNU-MacOSX/stockapp build/Debug/GNU-MacOSX/main.o -L../boost_1_60_0/boost -l boost
ld: library not found for -lboost

我正在尝试构建一个程序，它将下载网站HTML并解析HTML以从fiance.yahoo.com检索股票价格，这是未完成的代码：

using namespace std;

#include <cstdlib>
#include <iostream>
#include <fstream>
#include <string>
#include <vector>
#include <boost/asio.hpp> //code worked before adding this include

static string Index;      //initialize string hosting Index Name
static vector<string> Symbol;

int ReadIndexFile()
{
    string FileRead;
    string FileName;
    //string Temp;
    int count = 0;

    FileName = Index + "Symbols.csv";
    cout << FileName << "\n";

    ifstream source(FileName.c_str());//establishes source file
    while (!source.eof())           //reads source until end of file
    {
        while (getline(source, FileRead, ','))//retrieves source data to ',' and stores in temp
        {
            Symbol.push_back(FileRead);     //writes to array line by line
            cout << Symbol.at(count);
            count++;
        }
    }
}

int DownloadHTML()
{
    cout << "HTML Downloaded";
}

int main(int argc, char** argv) {
    cout << "Name your Index: ";
    cin >> Index;
    ReadIndexFile();
    DownloadHTML();
    return 0;
}

正如您可以在错误消息中清楚地看到未找到“Boost”库。

ld: library not found for -lboost

所以你需要使用以下命令安装它;

sudo apt-get install libboost-all-dev

希望这有帮助。

编辑：由于MAC不支持apt-get，因此您需要使用http://brew.sh/。有关Homebrew的详细信息，请查看此网址http://stackoverflow.com/questions/19688424/why-is-apt-get-function-not-working-in-terminal-on-mac-osx-10-9。
