c++ OSX 10.6.6 上提升 1_46_1。不链接

Question

我下载了c++ boost 1_46_1。解压它并按照安装说明进行操作。

我试图获得一个基本的增强程序来编译和链接，但到目前为止还没有运气。

这是 boost 程序

#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

您缺少 -lboost_program_options

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

Answer 2

您提供的链接器路径错误：

警告：目录 '~/usr/local/boost_1_46_1/stage/lib' 以下 -L 未找到

导致不链接您的对象

Answer 3

链接器输出包括以下行：

忽略不存在的目录“/Users/smith/usr/local/boost_1_46_1”

因此您期望库所在的位置与它们实际所在的位置之间存在一些不匹配...
