Question

我下载了c ++ boost 1_46_1。解压缩并遵循安装说明。

我试图获得一个基本的升级程序来编译和链接，但到目前为止没有运气。

这里是加速计划

#include <boost/program_options.hpp>
namespace po = boost::program_options;

#include <iostream>
#include <iterator>
using namespace std;

int main(int ac, char* av[])
{
  try {

    po::options_description desc("Allowed options");
    desc.add_options()
    ("help", "produce help message")
    ("compression", po::value<int>(), "set compression level")
    ;

    po::variables_map vm;        
    po::store(po::parse_command_line(ac, av, desc), vm);
    po::notify(vm);    

    if (vm.count("help")) {
        cout << desc << "\n";
        return 1;
    }

    if (vm.count("compression")) {
        cout << "Compression level was set to " 
        << vm["compression"].as<int>() << ".\n";
    } else {
        cout << "Compression level was not set.\n";
    }
}
catch(exception& e) {
    cerr << "error: " << e.what() << "\n";
    return 1;
}
catch(...) {
    cerr << "Exception of unknown type!\n";
}

return 0;
}

这是我的makefile

# compiler to use
CC = c++

INC = -I ~/usr/local/boost_1_46_1 
#-I /usr/include/c++/4.2.1
LIB=-L~/usr/local/boost_1_46_1/stage/lib
#LIB =-Lusr/local/lib 
#LIBNAME =-libboost_program_options.dylib
SOURCE = main.cpp

OUTPUT = out
all:
    $(CC) $(INC) $(SOURCE) -o $(OUTPUT) -v $(LIB) -dynamic

这是我得到的错误

Answer 1

你缺少-lboost_program_options

all:
    $(CC) $(INC) $(SOURCE) -o $(OUTPUT) $(LIB) -lboost_program_options -dynamic

Answer 2

您为链接器提供了错误的路径：

警告：目录'〜/ usr / local / boost_1_46_1 / stage / lib'跟踪-L未找到

导致无法关联您的对象

Answer 3

链接器输出包括以下行：

ignoring nonexistent directory "/Users/smith/usr/local/boost_1_46_1"

因此，您期望库的位置与实际位置之间存在一些不匹配...

在OSX 10.6.6上c ++ boost 1_46_1。没有链接
